USDA Pesticide Data Program Continues to Mislead the Public on Pesticide Residue Exposure

Thursday, February 15th, 2024

(Beyond Pesticides, February 15, 2024) The latest U.S. Department of Agriculture (USDA) pesticide residue report, the 32nd Pesticide Data Program (PDP) Annual Summary report, released in January, finds that over 72 percent of tested commodities contain pesticide residues (27.6 percent have no detectable residues), mostly below the level the U.S. Environmental Protection Agency (EPA) has set for tolerances (allowable residues) whose safety standards have been called into question by advocates. USDA spins its report findings as a positive safety finding because, as the Department says, “[m]ore than 99 percent of the products sampled through PDP had residues below the established EPA tolerances.” USDA continues, “Ultimately, if EPA determines a pesticide use is not safe for human consumption, EPA will mitigate exposure to the pesticide through actions such as amending the pesticide label instructions, changing or revoking a pesticide residue tolerance, or not registering a new use.” As Beyond Pesticides reminds the public annually when USDA uses the report to extol the safety of pesticide-laden food, the tolerance setting process has been criticized as highly deficient because of a lack of adequate risk assessments for vulnerable subpopulations, such as farmworkers, people with compromised health or preexisting health conditions, children, and perhaps, […]

Study Finds Pyrethroid Insecticide Levels in Newborns that Increase in First Year of Life

Friday, January 26th, 2024

(Beyond Pesticides, January 26, 2024) In addition to maternal (mothers) exposure, children experience exposure to pyrethroid insecticides earlier in life as levels significantly increase post-natal (after birth), according to a study published in Frontiers in Public Health. This study is one of the few studies to investigate pyrethroid exposure concentrations in the urine of newborns and children within their first year of life. However, this research reiterates what many other studies demonstrate on pyrethroids’ impacts on children’s health, primarily due to their notorious neurotoxic properties. The findings indicate that exposure to pyrethroids during pregnancy and early childhood exposure has links to adverse health effects, including neurodevelopmental delays (e.g., autism), behavioral issues (e.g., attention deficit [hyperactivity] disorder), and endocrine disruption (e.g., delay in puberty). Pesticide exposure during pregnancy is of specific concern as health effects for all life stages can be long-lasting. Just as nutrients are transferable between mother and fetus, so are chemical contaminants. Studies find pesticide compounds in the mother’s blood can transfer to the fetus via the umbilical cord. Therefore, pesticide exposure during pregnancy affects both the mother and child’s health. Beyond Pesticides has covered a variety of pregnancy risks from pesticides and other toxic chemicals, including these in just […]

Field Study of Bumble Bees Finds Exposure to Chemical Mixtures, High Hazard, Flawed Regulation

Tuesday, January 9th, 2024

(Beyond Pesticides, January 9, 2024) A “landscape-level” study finds that typical risk assessment studies used by the U.S. Environmental Protection Agency (EPA) and European regulators fail to “safeguard bees and other pollinators that support agricultural production and wild plant pollination.” The study, published in Nature (November 2023), evaluates the health of bumble bees (Bombus terrestris) as a sentinel species placed in 106 agricultural landscapes across Europe. The authors’ conclusions challenge “the current assumption of pesticide regulation—that chemicals that individually pass laboratory tests and semifield trials are considered environmentally benign”—calling into question EPA’s persistent failure to adequately regulate mixtures of chemicals to which organisms are exposed in the real world. This study adds to the body of science on pesticide mixtures adversely affecting bee and pollinator health. See here, here, and here. The failure to capture real-world exposure to pesticide mixtures in its regulatory assessments extends to EPA’s systemic failure to evaluate a range of serious adverse impacts, as noted by the agency’s Office of Inspector General (OIG) report. And, aquatic environments also have documented mixtures of pesticides, with the U.S. Geological Survey finding 90 percent of water samples containing at least five or more different pesticides. “We can take no comfort […]

Neonicotinoids Combined with Other Pesticides Elevate Hazards to Honey Bee

Wednesday, February 22nd, 2023

(Beyond Pesticides, February 22, 2023) Combining neonicotinoid insecticides with other commonly used pesticides can result in synergistic effects on honey bees, increasing toxicity more than any individual chemical could, according to research published in Scientific Reports earlier this month. The data highlight the grave inadequacy of the U.S. Environmental Protection Agency’s (EPA) process for evaluating pesticide risks. Under current regulations, EPA requires chemical manufacturers to submit data only on singular active ingredients. Yet, pesticide products may be packaged or â€tank mixed’ with other, equally toxic pesticides without any obligation to determine the toxicity of the material that is actually being applied. Independent research is left to fill in these gaps, and the data increasingly shows that toxicity with pesticide mixtures amounts to a roll of the dice: sometimes combinations are less toxic, sometimes their toxicities are merely additive. But more often than not, pesticide mixtures result in synergistic effects that make the product significantly more toxic than either individual chemical alone. To understand how pesticide combinations are harming pollinators, scientists began with baseline data on the individual toxicity range  that common pesticides pose to honey bee colonies. Research was conducted on honey bees reared in the Stoneville Wildlife Management Area […]

Indoor Air Pollution: Pesticides Continue to Make their Way Into Homes

Wednesday, February 1st, 2023

(Beyond Pesticides, February 1, 2023) A study published in Environment International concurs with previous reports that agricultural pesticide treatment can contaminate nearby residential areas, resulting in indoor chemical exposure via concentrations of insecticide active ingredients in house dust. Pesticide contamination in homes has ties to higher levels of pesticide residue in both human and pet bodies. Some pesticides, like organochlorine compounds, have poor elimination from the body, leading to accumulation over a lifetime. Pesticide exposure can heighten risks of various cancers (i.e., prostate, hepatic, liver, etc.), mental health problems (i.e., depression), respiratory illnesses (asthma), endocrine disruption, and many other pesticide-induced diseases. Extensive pesticide use can predispose human pathogenic to antibiotic resistance, bolstering bacterial virulence. Studies like this are concerning as it reveals that individuals do not have to be in close contact (e.g., chemical manufacturers, farmworker, gardener, custodian, etc.) with pesticides for risky, health-harming exposures to occur. Despite stricter regulations and technological changes beginning to decrease air pollution from cars and other vehicles, scientists are finding that the use of pesticides and other household chemicals represents an increasing proportion of U.S. smog-forming air pollution. Personal care products, cleaning agents, perfumes, paints, printing ink, and pesticides warrant greater attention from regulators for their ability to form toxic fumes that can eventually make their way […]

Reduced Productivity in Strawberries Pollinated by Neonic-Exposed Bees, Research Finds

Wednesday, September 21st, 2022

(Beyond Pesticides, September 21, 2022) Strawberry plants pollinated by wild bees exposed to neonicotinoid insecticides produce smaller berries than those pollinated by unexposed bees, finds research published in the journal PLOS One. The findings are yet another piece of evidence pointing to the need for major reforms in the way pesticides are evaluated and pollinators are protected in the United States. As decades of evidence have piled up on the dangers posed by long-lived, systemic, neonicotinoid insecticides, the U.S. Environmental Protection Agency (EPA) has done little to address the damage to pollinator populations, while needed legislation, the Saving America’s Pollinators Act, has languished in Congress without a hearing or a vote, despite having over 75 cosponsors. This new study describes a novel consideration for how neonicotinoids may harm pollinators and impact the food supply. “Previous studies have shown that clothianidin affects wild bees negatively in terms of foraging speed, development and reproduction. Our results indicate that it can also impair the bees’ ability to pollinate strawberry flowers,” says study coauthor Lina Herbertsson, PhD. Scientists established 12 outdoor cages each with 10 strawberry plants and 11 canola plants. For half of the cages, the canola plants were grown with seeds coated […]

Exposure to Synthetic Pyrethroids During Infancy Associated with Developmental Delays in Toddlers

Thursday, September 1st, 2022

(Beyond Pesticides, September 1, 2022) Low level exposure to synthetic pyrethroid insecticides at 6-8 months of age is associated with language development delays in two-year old toddlers, according to research published in Neurotoxicology this month. This is the latest study to link this class of chemicals to developmental delays in young children. Despite a steady drum of concerning research, the U.S. Environmental Protection Agency (EPA) in 2019 removed a crucial “safety factor” intended to protect children’s health from synthetic pyrethroids, allowing higher levels of the insecticides to be sprayed on food, in homes, and playing fields around the country.   To investigate the impact of synthetic pyrethroids on language development, scientists enrolled 327 expectant mothers in their third trimester. The mothers, all from rural areas of China, were selected if they had no history of significant pesticide exposure or family history of serious disease. Urine samples were taken from the women during pregnancy, and from infants 6-8 months after birth. Scientists analyzed samples for concentrations of three different synthetic pyrethroid breakdown products (metabolites), including 3-phenoxybenzoic acid (3PBA), 4-fluoro-3-phenoxybenzoic acid (4F3PBA), and cis-2,2dibromovinyl-2,2-dimethylcyclopropane-1-carboxylic acid (DBCA). While 3PBA is a metabolite of many synthetic pyrethroids, 4F3PBA a more specific metabolite of cypermethrin, […]

USDA Food Pesticide Residue Survey Raises Alarm, while Pesticide Industry and EPA Mislead Public

Friday, February 4th, 2022

(Beyond Pesticides, February 4, 2022) In January, the U.S. Department of Agriculture (USDA) issued its 30th Pesticide Data Program (PDP) Annual Summary report (which evaluates each year the presence of pesticide residues on produce) and misleads the public on the safety of food and agricultural practices. This 2020 report concludes that more than 99% of the produce samples tested showed residues below established U.S. Environmental Protection Agency (EPA) benchmark levels. At first blush, this sounds very reassuring, but Beyond Pesticides maintains that there is (always) more to the “safety” story, not least of which are serious deficiencies in EPA’s establishment of those “tolerances.” Those flaws include a lack of risk assessment for vulnerable sub-populations, such as farmworkers, people with compromised health, children, and perhaps, cultural/ethnic and regional sub-groups of the general population, and a failure to fully assess serious health outcomes such as disruption of the endocrine system (which contributes to numerous serious diseases). For everyone, Beyond Pesticides recommends choosing organic produce whenever possible — the vast majority of which does not contain synthetic pesticide residues. The PDP report asserts that “the data . . . illustrate that residues found in agricultural products sampled are at levels that do not pose […]

Pesticide Exposure Contributes to Preterm Births and Low Birth Weight

Thursday, November 18th, 2021

(Beyond Pesticides, November 18, 2021) A study published by King George’s Medical University, India, finds exposure to xenobiotic substances like pesticides during pregnancy increases risks associated with preterm birth, including a rise in cesarean section (C-section) deliveries and a decrease in fetal body weight. Preterm births occur when a fetus is born early or before 37 weeks of complete gestation. Premature births can result in chronic (long-term) illnesses among infants from lack of proper organ development and even death. Birth and reproductive complications are increasingly common among individuals exposed to environmental toxicants, like pesticides. The Center for Disease Control (CDC) reports the preterm birth rate is increasing annually. Therefore, studies like this can help government and health officials safeguard human health by assessing adverse effects following prevalent chemical exposure. The study notes, “To the best of our knowledge, this was a pioneering study, and it may help to increase our knowledge with regard to xenobiotic exposure in biological systems and the need for stringent guidelines for agricultural use of pesticides.” The study examines the association between the transfer of xenobiotics (foreign synthetic substances like pesticides) from mother to fetus. Transferal of these toxic substances can result in biological and chemical changes (i.e., genotoxicity […]

296 Chemicals in Consumer Products Increase Breast Cancer Risk Through Hormone (Endocrine) Disruption

Wednesday, July 28th, 2021

(Beyond Pesticides, July 29, 2021) New research published in Environmental Health Perspectives finds nearly 300 different chemicals in pesticides, consumer products, and contaminated resources (i.e., food, water) increase breast cancer risks. Breast cancer is the most common cancer among women, causing the second most cancer-related deaths in the United States. Past studies suggest genetic inheritance factors influence breast cancer occurrence. However, genetic factors only play a minor role in breast cancer incidences, while exposure to external environmental factors (i.e., chemical exposure) may play a more notable role. There are grave concerns over exposure to endocrine (hormone) disrupting chemicals and pollutants that produce adverse health effects. Most types of breast cancers are hormonally responsive and thus dependent on the synthesis of either estrogen or progesterone. Hormones generated by the endocrine system greatly influence breast cancer incidents among humans. Several studies and reports, including U.S. Environmental Protection Agency (EPA) data, identify hundreds of chemicals as influential factors associated with breast cancer risk. Therefore, advocates point to the need for national policies to reassess hazards associated with disease development and diagnosis upon exposure to chemical pollutants. The study’s researchers note, “This study shows that a number of chemicals currently in use have the ability to manipulate hormones known to adversely […]

Migrant Farmworkers Repeatedly Doused with Toxic Pesticides, Lawsuit Documents

Tuesday, December 15th, 2020

(Beyond Pesticides, December 15, 2020) Over two dozen Texan farmworkers working in Illinois fell ill after toxic pesticides were repeatedly sprayed over them via aircraft, according to a complaint filed in U.S. District Court this month. As the suit details, indiscriminate pesticide spray brought harm to several minors, elderly workers, and a pregnant mother. Plaintiffs are seeking numerous claims against Pioneer Hi-Bred, a subsidiary of Corteva (formerly DowDupont), as well as the aerial spray company and applicator that contaminated workers. These include violations of federal law and other tort, wage, contract, and damage claims. “No farmworker should be exposed to poisonous chemicals when doing their job, let alone multiple times in two weeks,” said Lisa Palumbo, Director of Legal Aid Chicago’s Immigrants and Workers’ Rights project, which filed the suit alongside several other legal advocacy groups. “Migrant farmworkers are some of our most vulnerable workers, who grow and harvest the food we eat. Their employer is obligated to ensure they are safe from pesticide exposure, and that they are properly cared for and provided truthful information if exposure occurs. This did not happen here.”   Two incidents are detailed in the complaint. With the first, occurring in July 2019, all […]

Monarch Butterfly Larvae Adversely Affected by Pesticide Drift from Contiguous Soybean and Maize Crop Fields

Thursday, April 23rd, 2020

(Beyond Pesticides, April 23, 2020) Pesticide spray drift from adjacent farmlands expose butterfly larvae to lethal pesticide concentrations, according to research published in Environmental Toxicology and Chemistry by Iowa State University (ISU). Lack of previous experimental pesticide toxicity data makes it unclear as to what degree insecticides impact monarch butterfly (Danaus plexippus) productivity in milkweed (Asclepias spp.) habitats near pesticide-treated pasture. This study adds weight to the idea that pesticides are playing a role in the ongoing decline of this iconic butterfly, as researchers find insecticide drift from adjacent fields to be strongly associated with larval mortality. Future monarch butterfly conservation efforts should consider risks stemming from pesticide exposure when developing butterfly rehabilitation efforts, according to advocates. As co-author Niranjana Krishnan (ISU graduate student) states, “In order to make the best decisions about how and where to plant milkweed, we first need to find basic toxicity and exposure data.”  ISU researchers established monarch butterfly colonies by collecting larvae from roadside milkweeds, which they then reared in the laboratory for incubation. To analyze the relative toxicity of various insecticides on monarch butterflies, researchers applied normal field-application rates of each pesticide at different larval development stages. Scientists used a bioassay to measure the […]

Common Bug Killers Used in Homes Persist for Over a Year

Friday, July 7th, 2017

(Beyond Pesticides, July 7, 2017) The active ingredients in commonly used bug sprays such as RAID leave significant residues that persist for over a year in the home, according to a study published by Brazilian researchers in the journal Environmental Toxicology and Chemistry. The pesticides tested, synthetic pyrethroids, have been linked to a range of health effects, most notably in children. The results of this study add to calls for homeowners to rethink a chemical-based approach to home pest control, in favor of simple, non-toxic practices. In the recent study, researchers compared the breakdown time of two synthetic pyrethroids, cypermethrin and beta-cyfluthrin, between laboratory conditions and those in an average home. Under lab conditions, with temperature controlled and without sunlight or ventilation, both active ingredients broke down little within the 112 day test period observed. However, the test house, where insecticides were applied according to indoor label conditions, displayed breakdown times similar to the lab results during the first 112 days. Researchers continued their observation of pyrethroids in the home for up to a year, finding after that period 44% of beta-cyfluthrin and 70% cypermethrin remained in household dust samples from the singular, original application. A 2014 study published by […]

Rusty Patch Bumblebee Officially Listed as an Endangered Species

Thursday, January 12th, 2017

(Beyond Pesticides, January 12, 2017) Yesterday marked a monumental event in the fight against pollinator declines, as the rusty patched bumblebee became the first bee species to officially be declared endangered by the U.S. Fish and Wildlife Service (FWS). According to FWS, endangered species designations are made when a species is “in danger of becoming extinct throughout all or a portion of their range.” Tom Melius, Service Midwest Regional Director for FWS, stated in a press release that, when it comes to this determination, “[FWS’s] top priority is to act quickly to prevent extinction of the rusty patched bumble bee. Listing the bee as endangered will help [the agency] mobilize partners and focus resources on finding ways right now to stop the decline.” Listed yesterday in the Federal Register, the ruling will go into effect February 10, 2017. This is a victory for environmental groups who have fought to protect the rusty patched bumble bee from widespread threats, such as habitat loss and pesticide use. According to FWS, the rusty patched bumble bee was once widespread across the United States and parts of Canada, but declined dramatically in the 1990s.  Since then, their populations have dwindled and their overall decline is estimated at 91 […]

Endangered Species Status Proposed for Rusty Patched Bumble Bee

Friday, September 23rd, 2016

(Beyond Pesticides, September 23, 2016) The U.S. Fish and Wildlife Service (FWS) has proposed listing the rusty patched bumble bee as an endangered species under the Endangered Species Act (ESA). This is a victory for environmental groups who have fought to protect the rusty patched bumble bee from widespread threats such as habitat loss and pesticide use. The FWS proposal opens a 60-day public comment to allow agencies, groups and interested people to comment and provide new information. The public comment period is open through November 21, 2016. You can submit comments soon by visiting the docket, here. According to FWS, the rusty patched bumble bee was once widespread across the United States and parts of Canada, but declined dramatically in the 1990s. Their populations dwindled and have declined by 91 percent. FWS acknowledged  that the bumble bee populations considered for this proposal have not been reconfirmed since the early 2000s, meaning that currently there may be even less of the species left. Threats to the rusty patched bumble bee include diseases introduced by commercial bumble bees that are not free of pathogens and are released near wild populations. Climate change plays a part, along with habitat loss from industrial […]

Study Finds Neonicotinoids Cause Compound-Specific Harm to Bumblebees

Monday, May 2nd, 2016

(Beyond Pesticides, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

Research Finds Bees Prefer Foods Treated with Bee-Killing Insecticides

Friday, April 24th, 2015

(Beyond Pesticides, April 24, 2015) Two new studies reporting on the adverse effects of neonicotinoids on bees were published Wednesday in the journal Nature, adding to a growing body of scientific literature linking the controversial class of pesticides to the global decline in bee populations. The conclusions reached by the two studies find that not only does neonicotinoid exposure result in reduced bee density, nesting, colony growth, and reproduction, but also that bees in fact prefer foods containing neonicotinoid pesticides despite their adverse effects. Neonicotinoids affect the central nervous system of insects, resulting in paralysis and eventual death. These pesticides have consistently been implicated as a key issue in pollinator declines, not only through immediate bee deaths, but also through sublethal exposure that causes  changes in bee reproduction, navigation, and foraging. The science has become increasingly clear that pesticides, either working individually or synergistically, play a critical role in the ongoing decline of honey bees. Pesticide exposure can impair both detoxification mechanisms and immune responses, rendering bees more susceptible to viruses, parasites, and other diseases, and leading to devastating bee losses. In one study, “Seed coating with a neonicotinoid insecticide negatively affects wild bees,” Swedish scientists report that wild bees […]

Behavioral and Emotional Problems in Children Linked to Insecticide Exposure

Friday, November 1st, 2013

(Beyond Pesticides, November 1, 2013) Insecticides commonly used in homes and schools are associated with behavioral problems in children, according to a recent study by Canadian researchers. The study investigates exposure to pyrethroid pesticides, used in more than 3,500 products, including flea and tick controls, cockroach sprays, and head lice controls. The study, Urinary metabolites of organophosphates and pyrethroid pesticides and behavioral problems in Canadian children, published in the journal Environmental Health Perspectives, raises serious concerns about the impact of pyrethroids, which are increasingly used as a replacement for organophosphates. This study uses data from the Canadian Health Measures Survey (2007-2009), a nationally representative survey, so researchers are able to apply these findings to the entire population of Canadian children. In a previous study among U.S. children, researchers at the National Health and Nutrition Examination Survey (NHANES) examined the metabolites of pyrethroids in children below the age of six. Similarly, they found pyrethroid insecticides in more than 70 percent of the samples, concluding that children had significantly higher metabolite concentrations than those of adolescents. Together these studies demonstrate that exposure is widespread, with real impacts to human health. In the recent study, researchers analyzed organophosphate and pyrethroid metabolites in the […]

Elevated Pesticide Exposure Documented in New York City Residents

Thursday, October 3rd, 2013

(Beyond Pesticides, October 3, 2013) According to new research, residents are more highly exposed to organophosphate and pyrethroid pesticides in New York City (NYC) than in the U.S. overall.  Researchers from the city’s Department of Health and Mental Hygiene reviewed the 2004 NYC Health and Nutrition Examination Survey (NYC HANES) to compare its pesticide exposure patterns in an urban environment with the nation as a whole. The NYC HANES includes a biomonitoring component to evaluate pesticide exposures by measuring concentrations of organophosphate and pyrethroid metabolites in urine. According to the authors, the findings underscore the importance of considering pest and pesticide burdens on cities, where a dense population results in a single exposure source affecting many people at the same time when regulating pesticide use. Organophosphate metabolites were measured in the urine of 882 New Yorkers, while 1,452 residents were tested for pyrethroid metabolites. As the researchers explain, the building density and disrepair in parts of NYC likely increased the chances of a pest infestation, which in turn can lead to the reliance on indoor pesticide use. By the 1980’s, organophosphates were the most common class of insecticides in the U.S., and were used indoors until the early 2000’s when […]

Another Study Finds Rootworms Resistant to Genetically Engineered Corn

Tuesday, September 3rd, 2013

(Beyond Pesticides, September 3, 2013) For the past several years, corn rootworms  have  been widely reported to exhibit resistance  to corn genetically engineered (GE) with the Bacillus thuringiensis (Bt) toxin. A  new report by  University of Illinois researchers found the resistant corn rootworm  in two of the state’s counties significantly damaged by western corn rootworm. The increasing lack of efficacy of GE corn, developed with the claim that it  is specifically designed to protect corn from rootworm, calls into question the efforts of agrichemical companies to patent new forms of GE crops. The report by Joe Spencer, PhD, and Michael Gray, PhD,  identifies significant damage from western corn rootworms in farm field that were planted with GE corn that contain a Bt protein referred to as “Cry3Bb1,” which has been inserted into nearly one-third of the corn planted in the United States. This version of Bt corn was introduced by Monsanto in 2003, and was touted as a way to reduce insecticide use against rootworm pests. Evidence was gathered in two Illinois counties, Livingston and Kankakee, after fields that had severe root pruning and lodging were brought to the attention of Drs. Spencer and Gray. Dr. Gray was quoted in […]

Bed Bugs Display Multiple Layers of Resistance to Pesticides

Tuesday, March 26th, 2013

(Beyond Pesticides, March 26, 2013) Scientists are learning more about the mechanisms bed bugs have developed to increase their resistance to the increasingly common class of pyrethriod pesticides. The study, published in the journal Scientific Reports in early March, adds further weight to calls from consumer health and environmental groups to adopt proven, non-toxic strategies to manage bed bugs and other household pest problems. After all, if alternatives exist, why put your family at risk with unsustainable, ineffective control methods? This latest research reveals something scientists had not suspected. Bed bugs are developing most of their resistance-associated genes on the outer layer of their shell. These genes either neutralize the insecticides before they can take effect, or slow down the toxins’ move towards the insects’ nerve cells. In addition, bed bugs in the study also show resistance developing within their nerve cells, the target site for the pesticides. This multilayered resistance is unique, scientists say, but, as Beyond Pesticides has long documented, pest resistance to pesticides is not. A 2011 study from Ohio State University reveals bed bugs’ ability to evolve hereditary changes in their production of certain enzymes, allowing them to excrete the toxins without being harmed. A study […]

Yet Again, Researchers Prove Bed Bugs Resistant to Common Pesticides

Thursday, June 7th, 2012

(Beyond Pesticides, June 7th, 2012) A new study confirms several other recent study findings on the inability of commonly used pyrethroid based pesticide products to control bed bug infestations. The results reinforce the voices of concerned citizens and environmental groups calling for a wider adoption of proven, non-toxic methods to manage bed bugs and other household pest problems. The study, entitled “Ineffectiveness of Over-the-Counter Total-Release Foggers Against the Bed Bug,“ was published in the June issue of the Journal of Economic Entomology. Researchers from Ohio State University focused on the efficacy of three over-the-counter ”˜foggers,’ or ”˜bug bombs,’ including Hotshot Bedbug and Flea Fogger, Spectracide Bug Stop Indoor Fogger, and Eliminator Indoor Fogger. Results from the study reveal that bed bugs are not affected by direct exposure to the pyrethriods present in these products. Even long-term laboratory populations of bed bugs, known to be susceptible to pyrethroids, were unaffected by the pesticide when given a thin cloth as cover. This means that even if the current strain of bed bugs in the U.S. were not resistant to pyrethriods, the chemical still would not be an effective method of control because of bed bugs’ propensity to hide in small cracks and […]

Take Action: EPA Proposes Expansion of Neurotoxic Pyrethroid Uses

Tuesday, January 31st, 2012

(Beyond Pesticides, January 31, 2012) The Environmental Protection Agency (EPA) has proposed an expansion in pyrethrins/pyrethroid insecticide uses as part of its cumulative risk assessment for this neurotoxic class of chemicals. In the cumulative risk assessment, EPA concludes that pyrethroids “do not pose risk concerns for children or adults,” ignoring a wealth of independent data that links this class of chemicals to certain cancers, respiratory and reproductive problems, and the onset of insect resistance. It went as far as to state that its cumulative assessment supports consideration of registering additional new uses of these pesticides, potentially opening the flood gates for manufacturers to bombard the market with more pyrethroid pesticides, endangering the health of the public. The agency is accepting public comments through February 8, 2012. Tell EPA that it has ignored numerous health effects and that these pesticides do pose unacceptable risks to human health given the availability of alternatives. Submit comments directly to the EPA docket or sign-on to Beyond Pesticides’ comments. In its comments to EPA, Beyond Pesticides states: There are several major concerns and flaws plaguing this cumulative assessment, which therefore does not meet the regulatory burden in fully evaluating synthetic pyrethroids’ effect on public and […]
