If you’re searching “raccoon in attic Richardson, TX”, there’s a good chance a raccoon has found a way into your attic and is using it for shelter, especially during colder months or when it’s raising babies. AAAC Wildlife Removal Dallas helps homeowners in Richardson and the greater Dallas area remove raccoons safely and humanely, with a process designed to stop the problem from coming right back. A raccoon in the attic can do more than make noise. They can tear insulation, damage ductwork, bend vents, rip soffits, and leave behind waste that creates strong odors and health concerns. The biggest mistake is waiting too long or trying DIY methods that scare the animal deeper into the attic. The smart move is a professional inspection to confirm entry points, identify nesting areas, and remove the raccoon the right way, especially if babies are involved. If you’re in Richardson or nearby areas like Plano, Garland, Addison, or North Dallas, reach out to AAAC Wildlife Removal Dallas to schedule an inspection. We’ll help you understand what’s happening, what the removal process looks like, and what practical prevention steps can help protect your attic long-term.

Even small amounts of these everyday ingredients can cause serious health issues—or be fatal—for these sensitive rodents.” Squirrels may look harmless scampering across your fence or chasing each other up a tree, but when they show up in your attic or tear through your garden, that charm disappears fast. In leafy neighborhoods where parks are close by and backyard bird feeders are everywhere, it’s no surprise that squirrels are regular visitors—and sometimes uninvited tenants. While many people enjoy watching them or even tossing out food, what you leave behind can actually be dangerous to squirrels—and a bigger headache for you without proper squirrel control . This article isn’t about harming wildlife. It’s about knowing what food is poisonous to squirrels so you don’t accidentally invite them in or make them sick. If you’ve been leaving out scraps, filling feeders, or composting without thinking twice, there’s a good chance you’re creating a squirrel buffet without even realizing it. Let’s break down what to avoid, what to secure, and how to protect both your home and the squirrels from a bad encounter. What Is The Most Dangerous Foods for Squirrels? Chocolate and Caffeinated Products Chocolate is one of the most toxic substances you can accidentally leave out for squirrels or any rodent. It contains theobromine—a stimulant that these small animals can’t metabolize effectively. Just a small amount from a brownie, chocolate almond bar, or sugar-filled candy can trigger tremors, elevated heart rate, or seizures in squirrels. Since they have such fast metabolisms and tiny bodies, the toxic effects hit hard and fast, often with serious consequences. Caffeinated foods and drinks are equally dangerous. Coffee grounds , soda spills, or chocolate-covered espresso beans tossed into a compost pile can be life-threatening if a squirrel gets into them. Where outdoor parties and backyard BBQs are common, it’s easy for sugary or caffeine-rich snacks to end up where rodents roam. To keep squirrels safe and your property clear of unwelcome visitors, make it a habit to clean up thoroughly and store all sweet or stimulant-laced foods securely. Avocados Avocados contain persin, a fungicidal toxin found in the fruit’s skin, pit, and even its leaves. While persin might not harm humans, it can be toxic to many animals, including squirrels. The risk isn’t just in eating an avocado—squirrels that nibble on a discarded peel, chewed seed, or exposed pit can experience digestive issues or worse. What makes this even more concerning is how easily avocado waste can be overlooked, especially in compost bins. If you’re growing avocado trees or preparing guacamole from scratch, this is something to stay mindful of. As urban farming and composting become more popular, the risk of accidentally exposing squirrels to this toxic fruit increases. Make sure avocado scraps are properly sealed or discarded, and if you have a tree, regularly clear fallen fruit from the yard. It’s better to be safe than to unknowingly poison a local animal. Onions, Garlic, and Spicy Foods While these aromatic kitchen staples may keep your chili full of flavor, they spell serious trouble for squirrels. Onions and garlic contain compounds that can damage red blood cells, leading to anemia and other health complications. The danger extends to cooked dishes, too. If a squirrel gets into leftover food seasoned with garlic or onions, even in small amounts, it can suffer lasting effects. In worst cases, repeated exposure can be fatal over time. Spicy foods also pack a punch that squirrels can’t handle. Hot sauce remnants, chili powder, or discarded tacos can cause severe digestive distress. Where spicy dishes are a staple, food waste often ends up in outdoor bins or compost piles. Make sure spicy scraps are stored in critter-proof containers, and avoid tossing seasoned leftovers near your patio or yard. The goal isn’t just to avoid harming squirrels—it’s to stop inviting them altogether. Alcohol and Fermented Fruit Alcohol might seem like an unlikely threat to wildlife, but squirrels are highly sensitive to it. Whether it’s beer spills from a tailgate, wine left out on the porch, or sugary cocktails left on patio tables, these drinks can lead to disorientation, slowed reaction time, and eventually liver failure in squirrels. Their small bodies can’t handle even trace amounts, and it doesn’t take much to put them in serious danger. Another sneaky culprit? Overripe or fermenting fruit, especially in backyards with peach, fig, or persimmon trees. As the fruit falls and begins to break down, it can release natural alcohols that attract squirrels and get them intoxicated. They may stagger, fall from trees, or become easy prey for predators. Regularly clean up fruit from the ground and keep alcoholic beverages secure during outdoor events. Salty Snacks and Chips Salt is another ingredient that can easily disrupt a squirrel’s internal balance. While humans can handle a salty snack during a football game or backyard hangout, squirrels don’t process salt well. Even a few bites of junk food like chips, pretzels, or salted walnut snacks can dehydrate them and overwork their kidneys. These types of treats also contain added sugar and artificial ingredients that offer zero nutritional value for squirrels—making them both harmful and useless from a dietary perspective. Many of these items—especially sugary breakfast cereals or processed snack mixes—are casually dropped or tossed outside without much thought. But to a hungry squirrel, that forgotten bowl of cereal or spilled trail mix is a full meal. Where outdoor events, food trucks, and weekend cookouts are part of the culture, squirrels quickly learn where the good stuff is. Cleaning up sugary crumbs and sealing snack waste tightly are easy steps that help discourage squirrels from turning your yard into their favorite buffet line. Surprising “Healthy” Foods That Still Poisonous To Squirrels Not all squirrel-dangerous foods are obviously harmful. Some look totally natural or even nutritious—but for squirrels, they can cause more harm than good. These foods often show up in gardens, bird feeders, compost piles, or well-meaning attempts to “feed the wildlife.” Here’s what to watch for. Raw Corn (Especially Moldy Corn) Corn might seem harmless—it’s a common ingredient in bird seed, livestock feed, and even human snacks. But when corn starts to mold, it can develop aflatoxins, which are highly toxic to squirrels and many other animals. Aflatoxins are produced by certain types of fungi and can affect liver function, immune systems, and even lead to cancer in wildlife. A squirrel doesn’t have to eat much moldy corn for it to cause serious internal damage. The risk goes up during warm, humid stretches—especially in summer—when moisture speeds up mold growth. Corn that’s left outside for too long, stored improperly in feeders, or tossed into compost piles can quickly become a hidden hazard. If you’re putting out corn in a feeder, store it in a dry place, change it frequently, and never offer anything that smells off or looks discolored. It’s not just about nutrition—it’s about safety. Bread and Processed Carbs Bread might feel like a safe, throwaway snack for critters—but it’s actually a poor and potentially harmful food choice for squirrels. Bread, crackers, and other refined carbs offer little to no nutrition, and they can expand in a squirrel’s stomach, leading to bloating or discomfort. In some cases, processed bread products contain preservatives and additives that are hard for squirrels to digest, weakening their system over time. Squirrels that eat too much bread often end up malnourished despite feeling full. This is especially common in neighborhoods where residents leave out food “just to be nice.” Unfortunately, the kindness backfires. Instead of helping, you may be attracting squirrels that grow dependent on an unhealthy food source—and more likely to take up permanent residence in your attic. If you want to be squirrel-friendly, stick to natural deterrents and avoid the bread basket. Peanuts (Especially Salted or Moldy) Peanuts are a bit of a wildcard. While they’re often seen in squirrel food blends or used to lure wildlife for photos, they aren’t actually nuts—they’re legumes. And when they’re salted, roasted, or worse, moldy, they become a serious risk. Moldy peanuts, like corn, can carry aflatoxins that attack a squirrel’s liver and immune system. Salted peanuts, on the other hand, can cause dehydration and kidney stress. This matters because many people use peanuts to feed birds or squirrels without realizing the risks. In fact, some birdseed mixes from big-box stores still include them. If you’re trying to keep squirrels away from your yard—or avoid poisoning them by accident—skip the peanuts. And if you must use them, go for raw, unsalted, and fresh, and use a squirrel-proof bird feeder so your effort to help one species doesn’t endanger another. Foods That Attract Squirrels (But Shouldn’t) Some foods might not be poisonous, but they’re basically neon signs saying “Free Snacks Here!” for squirrels. These attractants can lead to more frequent visits, nesting, and eventual infestations. If you’re trying to squirrel-proof your yard or keep them from invading your home, these are the items to manage carefully. Bird Seed and Pet Food Bird feeders are one of the top culprits for squirrel problems. Many blends contain sunflower seeds, millet, corn, and peanuts—aka squirrel candy. Once they find a reliable food source, squirrels will return again and again, sometimes destroying the feeder in the process. The same goes for pet food left outside. Dry kibble and wet food alike are high-protein, calorie-dense meals that squirrels will happily devour. Where backyard birdwatching is popular and outdoor pet bowls are commo

For environmentally transmitted pathogens, the host space use interacts with both the host social structure and the pathogen’s environmental persistence (which determines the timelag across which two hosts can transmit). Together, these factors shape the epidemiological dynamics of environmentally transmitted pathogens. While the importance of both social and spatial structures and environmental pathogen persistence has long been recognized in epidemiology, they are often considered separately. A better understanding of how these factors interact to determine disease dynamics is required for developing robust surveillance and management strategies. Here, we use a simple agent-based model where we vary host mobility (spatial), host gregariousness (social) and pathogen decay (environmental persistence), each from low to high levels to uncover how they affect epidemiological dynamics. By comparing epidemic peak, time to epidemic peak and final epidemic size, we show that longer infectious periods, higher group mobility, larger group size and longer pathogen persistence lead to larger, faster growing outbreaks, and explore how these processes interact to determine epidemiological outcomes such as the epidemic peak and the final epidemic size. We identify general principles that can be used for planning surveillance and control for wildlife host–pathogen systems with environmental transmission across a range of spatial behavior, social structure and pathogen decay rates.

Mayor) Malaria parasites of nonhuman primates (NHPs) are increasingly recognized for their zoonotic potential and complicate malaria control efforts ( 1 ). The first report of a zoonotic malaria parasite capable of infecting humans was Plasmodium knowlesi , which emerged as a major cause of human malaria in Southeast Asia ( 2 ). In South America, P. brasilianum (morphologically, genetically, and immunologically indistinguishable from P. malariae ) ( 3 ) and P. simium (closely related to P. vivax ) ( 4 ) parasites have been detected in NHPs and implicated in zoonotic infections ( 5 , 6 ). The Amazon basin harbors high biodiversity and dense human–wildlife overlap, particularly within Indigenous territories ( 7 ). Indigenous Peoples and local communities live in malaria-endemic areas with limited access to health systems and maintain close contact with wildlife ( 8 ), which creates favorable conditions for cross-species transmission of pathogens, including malaria parasites ( 9 ). This convergence of factors amplifies the risk for zoonotic and anthroponotic malaria transmission. Reports of natural infections with P. vivax , P. simium , P. brasilianum , P. malariae , and P. falciparum parasites in all neotropical NHP families underscore their potential reservoir role ( 8 , 10 – 12 ). Furthermore, experimental infections of neotropical NHPs with zoonotic malaria parasites from Asia raise concerns about the vulnerability of NHPs to emerging zoonoses ( 13 ). Despite global declines in malaria incidence ( 14 ), progress in the Amazon is hindered by ecologic complexity, vector diversity, and high rates of subpatent infections ( 15 ). A recent study conducted in a remote community in the northeastern Peruvian Amazon reported a P. vivax prevalence of 56.0% based on quantitative PCR (qPCR) results; nearly half of the infections were submicroscopic, highlighting the persistence of hidden reservoirs despite ongoing control interventions ( 16 ). Subclinical and mixed infections, common in malaria-endemic areas, evade standard diagnostics and are rarely captured in surveillance systems ( 17 ). Despite this fact, malaria-control efforts remain focused on P. falciparum and P. vivax parasites, and little attention is given to NHP-associated species such as P. brasilianum or P. malariae ( 18 ). Detecting hidden transmission dynamics requires highly sensitive, specific molecular tools and ethical field strategies ( 19 , 20 ). In remote forest settings, community-based methods, such as analyzing blood from legal subsistence hunting, can provide access to hard-to-reach wildlife populations while respecting Indigenous sovereignty ( 21 ). We investigated the molecular epidemiology of Plasmodium infections in sympatric humans and NHPs within a remote Indigenous territory in the Peruvian Amazon. By using blood samples from 141 Indigenous inhabitants and 341 neotropical NHPs (from 10 species) hunted for subsistence during an 11-year long-range wildlife collection program, we applied multigene molecular diagnostics and phylogenetic analysis to assess parasite prevalence, diversity, and evidence of cross-species transmission. Study Area Figure 1 Figure 1 . Geographic location of study of zoonotic and anthroponotic Plasmodium spp. circulation between wild primates and Indigenous community, Peruvian Amazon, 2007–2020. Red dot indicates Yagua Indigenous community of Nueva Esperanza,... We conducted this study in the Yavari-Mirin River basin, a remote upland forest region in the northeastern Peruvian Amazon. The area spans 107,000 hectares and includes a single Indigenous Yagua community, Nueva Esperanza, inhabited by 343 people in 2020. The community is located 302 km from the city of Iquitos and is surrounded by high biodiversity, including preserved populations of 14 NHP species ( 22 ). Malaria is endemic in the region; P. vivax is the most prevalent species. Villagers depend on subsistence activities (e.g., hunting, fishing, other forestry resources, and small-scale agriculture) and opportunistically trade wood, fish, wild meat, and agricultural products ( Figure 1 ). Ethical Considerations All human study procedures were approved by the Ethics Committees of Universidad Peruana Cayetano Heredia (approval no. 102142), Universitat Autònoma of Barcelona (Comisión de Ética en la Experimentación Animal y Humana approval no. 4829), and Hospital Clínic of Barcelona (approval no. HCB/2019/1107) and authorized by local and regional authorities of Nueva Esperanza (approval no. 267–2019-GRL-DRSL/30.09.01). NHP sampling was approved by the Peruvian Forest and Wildlife Service (approval no. 258–2019-MINAGRI-SERFOR-DGGSPFFS) and the Institutional Animal Use Ethics Committee of the Universidad Peruana Cayetano Heredia. We exported wildlife samples under Servicio Nacional Forestal y de Fauna Silvestre permits (nos. 003258/SP, 003260/SP, 003568-SERFOR, and 003579-SERFOR). Study Design and Blood Samples In February 2020, we conducted a cross-sectional survey in Nueva Esperanza. We obtained whole blood samples through venipuncture from 141 participants (41.1% of the population) with informed consent, assent, or both. We referred participants with microscopic or clinical suspicion of malaria during the study to the community health center and treated them according to malaria management guidelines of Peru’s Ministry of Health (Supreme Decree no. 273–2025-MINSA). In addition, we collected 17 samples from field workers; 5 were microscopically positive for P. vivax and had symptoms compatible with P. vivax infection; we molecularly analyzed samples of 3 of those workers and included results for sequence comparison only. Given the frequent malaria reports in Nueva Esperanza, field researchers received doxycycline as malaria chemoprophylaxis, in accordance with US Centers for Disease Control and Prevention (CDC) recommendations ( 23 ). During 2007–2020, we collected dried blood spots (DBS) from 341 free-ranging NHPs (representing 10 species and 4 families) as part of a long-term wildlife monitoring program. Local hunters, trained in ethical sample collection, collected blood onto filter paper during postmortem handling of legally hunted animals. Species, sex, and date were recorded. The procedure was performed for all groups of mammals and birds (not only for wild NHPs) to avoid encouraging hunting of NHPs. The species sampled included 143 Poeppig’s woolly monkeys ( Lagothrix lagothrica poeppigii ), 57 large-headed capuchin monkeys ( Sapajus macrocephalus ), 43 black spider monkeys ( Ateles chamek ), 29 Ucayali bald uakaris ( Cacajao calvus ucayalii ), 21 red howler monkeys ( Alouatta seniculus ), 19 Humboldt’s white-fronted capuchin monkeys ( Cebus albifrons ), 16 monk saki ( Pithecia monachus ), 8 Ecuadorian squirrel monkeys ( Saimiri macrodon ), 4 coppery titi monkeys ( Plecturocebus cupreus ), and 1 brown-mantled tamarin ( Leontocebus fuscicollis ). Microscopic Examination We examined thick blood smears for 135 participants; 10 were positive and all confirmed by molecular assays. Because of low positivity and variable slide quality, we excluded microscopic examination results from analyses. Molecular Diagnosis of Plasmodium Species We extracted DNA from whole blood and DBS by using the AllPrep DNA/RNA Mini Kit (QIAGEN, https://www.qiagen.com ). We collected all DBS from NHP in remote field conditions during 2007–2020, often with low DNA concentration and partial degradation. Therefore, we selected molecular targets to maximize sensitivity in cases of low parasitaemia and degraded material. We detected parasites by using 2 nested PCRs and 2 commercial VIASURE qPCR diagnostic kits (Certest Biotec, https://www.certest.es ) targeting mitochondrial cytochrome oxidase b ( cytb ), cytochrome c oxidase III ( cox3 ), and 18S SSU rRNA genes. For quantitative analyses, we generated a standard curve by using serial dilutions of the kit’s Malaria Quantitative Standard (≈2 × 10 7 copies/µL) to estimate genome copy number. We converted cycle threshold values to DNA copies/µL and log 10 -transformed for statistical comparisons. Because of gene 18S rRNA copy number variability among Plasmodium species, our estimates reflect relative (not absolute) parasitemia. Partial Amplification of cytb Gene We performed nested PCR (nPCR) for cytb to detect Plasmodium spp. parasites in both humans and NHP samples, as described previously ( 24 ). PCRs included appropriate positive and negative controls and were processed under protocols that prevented contamination. We sequenced amplicons for species confirmation. Validation of Plasmodium spp. Detection Figure 2 Figure 2 . Workflow for molecular detection and validation of Plasmodium spp. infections in study of zoonotic and anthroponotic Plasmodium spp. circulation between wild primates and Indigenous community, Peruvian Amazon,... We validated a subset of 54 human and 81 NHPs samples at Leibniz Institute for Zoo and Wildlife Research (Berlin, Germany) ( Figure 2 ) by using cox3 nPCR and sequencing. The cox3 nPCR uses genus-specific primers for the primary PCR, whereas the secondary PCR uses species-specific primers. The genus-specific primers were desi

Credit: Oregon Department of Transportation Lawmakers have included funding for wildlife crossings in a bipartisan transportation package that the U.S. House of Representatives will vote on in the coming weeks. The House Transportation and Infrastructure Committee plans to introduce the Building Unrivaled Infrastructure and Long-term Development for America’s 250 th , also known as the BUILD America 250 Act, which, if passed, would invest in roads, bridges and transit infrastructure nationwide while reauthorizing the Wildlife Crossings Pilot Program. The BUILD America 250 Act would provide $80 million annually for the program from fiscal years 2027 through 2031. The bill also looks to increase access to transport grant programs by removing the requirement that Tribes match federal funds. Instead, the federal government would fully fund approved projects. The change would increase Tribal access to the Wildlife Crossings Pilot Program as well as Aquatic Organism Passage and Better Utilizing Investments to Leverage Development, otherwise known as BUILD grants. “You can’t have a big-league economy with little-league infrastructure,” said Rep. Rick Larsen (D-WA). “The BUILD America 250 Act makes key investments in the nation’s transportation—from restoring aging bridges and repairing crumbling roads to building out safe, accessible transit and bike infrastructure.” Read more in the press release from the Committee on Transportation and Infrastructure .

Scientists at UC Riverside have identified a cheaper, highly effective way to kill western drywood termites by drawing them toward insecticide instead of trying to track down every hiding place. In experiments tied to a study in the Journal of Economic Entomology , the team used pinene, a pleasant-smelling compound released by forest trees, to make the insects move toward treated wood. The result was a major jump in effectiveness, from about 70% mortality with insecticide alone to more than 95% when pinene was added. "We saw significant differences in the death rates using insecticide alone versus the insecticide plus pinene," said UCR entomologist Dong-Hwan Choe, who led the discovery. "Without pinene, we got about 70% mortality. When we added it in, it was over 95%." Why western drywood termites are such a problem Western drywood termites are native to North America and play a real role in nature by helping break down dead wood above ground with help from microorganisms in their guts. "They are recyclers," Choe said. "And they're very common." That ecological role becomes a serious headache when the same insects move from dead trees into houses. They do not distinguish between natural wood and structural lumber, which is why they are a persistent concern in places such as California and Florida, as well as parts of Canada and Mexico. "It's only a matter of time before termites attack a house, especially in warmer parts of the states," Choe said. The limits of fumigation One of the most widely used treatments for drywood termites is fumigation, in which a home is sealed under a tent and filled with gas to kill the insects. California relies on this approach more than any other U.S. state, according to UC Riverside. But fumigation has drawbacks. The industry has been under pressure to find alternatives because sulfuryl fluoride, the chemical used in fumigation, is toxic to humans and also acts as a greenhouse gas. It is also costly, and it does not stop a home from becoming reinfested later. "Even though it is very thorough, a home can be infested again soon after fumigation is completed," Choe said. "Some people fumigate every three to five years because it doesn't protect structures from future infestations." How pinene helps insecticide work better Another option is localized injection. In this method, pest control workers drill into infested wood, reach the termite "gallery" or hiding area, and inject insecticide directly inside. Because it targets a smaller area, localized treatment can use fewer chemicals and cost less than fumigation. It may also leave treated wood better protected against future infestations. "This is a more localized treatment, and in theory, it is a better strategy when you want to control drywood termites with fewer chemicals. It's less expensive, and the treated wood may also stay protected from future infestations," Choe said. The big challenge is finding where the termites actually are inside the wood. These insects can spread through complex tunnel systems, and standard contact insecticides only work if the termites physically touch the treated area. That is where pinene changed the equation. The scent appears to draw termites from a distance, reducing the need to pinpoint every hidden pocket before treatment. "Even at low concentrations, pinene is good at attracting termites from a distance," Choe said. "We don't think it's functioning as a pheromone," Choe said. "We think the scent is more associated with their food. Smells nice… dinner time! That's the concept that we had in mind." The insecticide used in the study The insecticide used in the 2024 study was fipronil, which is also used against ants. Fipronil can harm aquatic insects and pollinators if it escapes into the environment, but in this case it was injected into wood, which lowers the chance of off-target effects. Choe's lab focuses on how urban insect pests communicate chemically, with the goal of turning that knowledge into smarter control strategies for pests such as western drywood termites. "Our study shows that if you understand insect behavior better, it's interesting by itself," Choe said. "Then there are also important implications for more effective pest management, so we can use fewer chemicals without compromising efficiency."

At this very moment, long-standing programs and staff are being slashed from the agency charged with this very purpose: the Environmental Protection Agency (EPA). Environmental protections are critical for the health of our ecosystems and communities, and the science and regulatory capacity of the EPA exists to prevent the dire adverse health outcomes caused by environmental pollution–for people and wildlife. Without efforts to protect us, we risk exposure to toxins of the past and present–a fight that has been going on in the United States for decades. In the spirit of celebrating the National Wildlife Federation (NWF)’s 90th anniversary, it is important to reflect on both the progress and the challenges that the environmental and conservation movements have faced over the last century. When NWF was founded in 1936 at the first North American Wildlife Conference in Washington D.C., the goal was to “unite the voices of conservationists” and work to advance conservation policies at the national level, setting the stage for federal protections for wildlife and the environment, particularly with respect to unregulated hunting and over-exploitation of natural resources. When the second World War began, a few years after NWF’s founding, much of society’s focus shifted to human survival and preventing avoidable disease and death. DDT (dichloro-diphenyl-trichloroethane), a chemical insecticide that was initially thought to be relatively safe, was introduced and widely used to combat insect-borne diseases like malaria and typhus that were killing soldiers and civilians , and later used for agricultural pest control. With the 1962 release of Rachel Carson’s influential Silent Spring , the public became aware that DDT had devastating effects on bird populations. As described in Carson’s book, a “silent spring” is a season without birdsong, as DDT decimated egg shells of several bird species, leading to plummeting populations. Concerned about the loss of beloved species like bald eagles and peregrine falcons, the American people united in organizations like NWF to demand national-level bans on toxins like DDT. When giving his State of the Union address in January of 1970, President Nixon stated that “restoring nature to its natural state is a cause beyond political party and beyond factions… it has become a common cause of all the people of this country.” So, thanks to the widespread advocacy and support from organizations and the general public across the country, the Environmental Protection Agency (EPA) was established in December of 1970–34 years after NWF was founded. It wasn’t until DDT was banned in 1972 by the EPA that bird populations were able to begin recovering. For humans, DDT is now associated with increased risk of certain cancers and is harmful to the reproductive and nervous systems . Just think about it: how many lives–and species–could have been lost if the EPA hadn’t banned DDT? Bald eagle. The same year that the EPA was established, the Clean Air Act of 1970 was passed, expanding the role the federal government had in regulating pollution in the United States. Under the Clean Air Act, the EPA sets National Ambient Air Quality Standards (NAAQS) for six common air pollutants known as criteria air pollutants. Particulate matter (PM), one of the six criteria air pollutants, is a mixture of solid particles and liquid droplets found in the air, produced largely by industrial activities and motor vehicles. Particulate matter is categorized into two size classes: PM2.5 (less than 2.5 micrometers in diameter) and PM10 (2.5 – 10 micrometers in diameter). While PM10 is a primary pollutant, which comes directly from a polluting source (like a dusty road or a factory), PM2.5 can be both primary and secondary (resulting from chemical reactions of gases in the atmosphere). The extremely small size of these particles allows them to travel deep into our bodies, including our lungs, bloodstream, and more, and cause significant harm to the health of people and wildlife. In January of 2026 , the EPA announced that it will weaken air pollution standards for new power plants and no longer factor the economic cost of human health into decisions about pollution regulations. This is dangerous for our health and the health of wildlife, because it means greater exposure to pollutants like PM, which sickens wildlife as well as people . And with increasing energy demand in the United States driving up electricity generation, it is all the more important that regulations protecting the air we breathe are strengthened, not weakened. PFAS (per- and polyfluoroalkyl substances) are a group of thousands of synthetic chemicals that have been widely used in consumer products since the 1950s. They are man-made, long-lasting chemicals that are found nearly everywhere, from the water we drink and the food we eat to our lands, homes and workplaces . Scientists have found that PFAS are in the blood of nearly 97% of Americans that have been tested, and in wildlife across the globe, from alligators in North Carolina to polar bears in the Arctic . Similar to DDT, and even more recent pesticides like neonicotinoids , PFAS “bioaccumulates,” or increases in concentration in the tissues of organisms as it moves up the food web, which not only harms wildlife, but also the people who hunt and fish them. Also, once they have entered the environment, they are nearly impossible to eradicate. PFAS differs from DDT in its use cases–while DDT was originally used to protect humans from insect-borne diseases, PFAS are largely utilized for convenience in commercial products, such as textiles, cleaning products, personal care products, and other household items . The impacts of PFAS are only recently beginning to come to light, with studies linking exposure to certain levels of PFAS to increased risk of cancer, developmental impacts in children, reduced immune system function, and more . Similar impacts have been reported in wildlife species . Even still, scientists do not yet have a full picture of the long-term impacts of PFAS on human health and wildlife. Despite this, the administration is loosening PFAS regulations , and the Office of Research and Development at EPA is being entirely dismantled , hampering the nation’s ability to further investigate and regulate the impacts of emerging pollutants like PFAS. Looking back on our very recent history–during which we narrowly avoided catastrophe by effectively researching and then banning DDT–we know we must now act swiftly to ensure we don’t repeat the past, or worse. It is our duty as Americans to stand up for the rights and protections that allow us to live healthy lives–for ourselves, wildlife, and future generations. The EPA’s ability to conduct independent research and inform and enforce environmental policy is what brought us out of a dangerously polluted past. In the face of continued industrial and non-point source pollution, the future health of people, wildlife and the environment depends on the future of the EPA. For decades, Americans have benefited from the EPA’s ability to implement environmental protections such as the Clean Water Act, the Clean Air Act, and the Federal Insecticide, Fungicide, and Rodenticide Act. The recent repeal of the Endangerment Finding , and elimination of the Office of Research and Development are some examples of actions that reduce the credibility of the EPA. If the EPA isn’t enforcing these policies, who is? Air, water, and chemical toxins are a continuous threat, and we need the enforcement of protections now more than ever. Just as President Nixon asserted in 1970, public and environmental health should be a non-partisan issue. Our representatives in Congress have the power to ensure that the EPA carries out its mission: to protect human health and the environment. These policies affect all of us, just as they did during the founding of NWF and the EPA. You can continue to be informed, advocate for these critical protections, and use your vote to protect human and wildlife health.

Courtesy of UBC Okanagan Four decades of satellite image analysis have revealed that some of Canada’s regions most resilient to the impact of climate change lack protections. Meanwhile, national parks and other areas may experience quicker change in the future. In a study published recently in Communications Earth & Environment , TWS member Michael Noonan, an assistant professor in biology at the University of British Columbia Okanagan, and his colleagues examined daily satellite vegetation data from 1981 to 2025. This information helped them determine the relative unpredictability of weather patterns across the country. While unpredictable weather has generally increased over this time, it isn’t spread evenly. The researchers found that protected areas often had unpredictable weather, while predictable weather patterns often occurred in unprotected areas. “Some parts of Canada tend to be relatively stable year after year, while others swing wildly,” Noonan said. “What we’ve shown is that this pattern of instability has real, measurable consequences for biodiversity. And our protected areas weren’t designed with any of this in mind.” Noonan said that when considering future areas to protect, authorities should consider protecting these resilient areas.

As commercial hives across the United States struggle to survive attacks from deadly parasites, a distinct hybrid bee found in this region is showing a surprising ability to endure. Beekeepers across the country reported losing as much as 62% of their managed honeybee colonies in 2025, raising serious concerns about food production. These losses are linked to several pressures, including pesticide exposure, climate stress, shrinking habitats, and паразites. Among the most damaging threats is the Varroa mite. How Varroa Mites Damage Honeybees Varroa mites weaken bees by feeding on their fat body tissue, an essential organ that supports immune function, metabolism, and energy storage. If you were comparing it to human biology, it performs roles similar to the liver, pancreas, and immune system. As a result of this damage, bees lose weight, become more vulnerable to disease, and have shorter lifespans. The mites also spread dangerous viruses such as Deformed Wing Virus and Acute Bee Paralysis Virus by injecting them directly into a bee's bloodstream. To combat infestations, beekeepers often rely on chemical treatments, but these solutions can become less effective over time. Study Finds Natural Mite Resistance in Hybrid Bees New research from UC Riverside, published in Scientific Reports , offers a rare piece of good news. The study is the first to demonstrate that a locally adapted group of honeybees can consistently and naturally keep mite populations under control. "We kept hearing anecdotally that these Californian honeybees were surviving with way fewer treatments. I wanted to test them rigorously and understand the driving force behind what the beekeepers were seeing," said Genesis Chong-Echavez, a UCR graduate student and lead author of the study. Working with entomologists from UCR's Center for Integrative Bee Research (CIBER), Chong-Echavez tracked 236 honeybee colonies from 2019 through 2022. Fewer Mites and Less Need for Treatment The results showed that these bees are not completely resistant, but they perform far better than typical commercial colonies. Colonies led by locally raised hybrid queens carried about 68% fewer mites on average compared to those led by commercial queens. They were also more than five times less likely to reach levels where chemical intervention becomes necessary. These bees are not part of any commercial breeding program. Instead, they come from a naturally mixed population in Southern California, often originating from feral colonies living in trees. Genetic studies reveal that they combine traits from at least four honeybee lineages, including African, Eastern European, Middle Eastern, and Western European bees. Larval Stage May Hold the Key To understand why these bees perform better, researchers conducted lab experiments focusing on developing larvae. Varroa mites must enter brood cells to reproduce, so the team tested whether mites were equally attracted to larvae from different types of colonies. They were not. Mites showed less interest in larvae from the hybrid Californian bees, especially at around seven days old, when larvae are usually most vulnerable. This suggests that the bees' defense may begin early in development, before adult behaviors play a role. "What surprised me most was the differences showed up even at the larval stage," Chong-Echavez said. "This suggests the resistance mechanism may go deeper than some kind of behavior and may be genetically built into the bees themselves." Implications for Global Honeybee Health The findings could have significance far beyond Southern California. Honeybees are essential pollinators responsible for crops worth billions of dollars, yet they continue to face mounting environmental pressures. This research points to the possibility that natural biological traits could help strengthen bee populations. Boris Baer, a UCR entomology professor and co-author of the study, emphasized the importance of collaboration with beekeepers. "This question did not start in the lab. It started in conversations with beekeepers," Baer said. "They were not just observers; they helped shape the questions behind this research." What Comes Next Researchers stress that these hybrid bees are not completely free of mites, and current management practices should not be abandoned. Instead, the goal is to identify the specific traits that allow these bees to keep mite levels lower and explore how those traits could support breeding efforts or reduce reliance on chemicals. Future studies will focus on uncovering the genetic, behavioral, and chemical signals that may make the larvae less attractive to mites. "At a time when pollinators are facing global decline, this work offers a hopeful message: solutions may already be emerging in the field, and we just need to understand them," Chong-Echavez said.
