(Beyond Pesticides, October 28, 2010) In an effort to combat a bedbug problem in a Brooklyn, New York elementary school, the Department of Education (DOE) paid a private contractor almost $100,000 to exterminate and, according to teachers, left the classrooms “soaked with a liquid bed bug killing chemical.” An odorous fluid was left behind on children’s and teacher’s desks, books and on the floors. ABC 7 Online reports the unknown pesticide substance is being tested, but teachers and parents will not know the results and what they were exposed to for another two weeks. The teacher’s union estimates that cleaning up the classroom will cost over twice what was paid, and the DOE plans to bill the contractor and stop the company from future business in the city, according to the news report. This story showcases the importance of a comprehensive school and community pesticide and pest management policy in response to the mass hysteria that bedbugs are causing and as a general public health protection measure. The bedbug outbreak prompted the U.S. Environmental Protection Agency (EPA) to issue warnings against improper treatments and misuses of pesticides. Despite the fact that bed bugs do not transmit diseases and are not […]

(Beyond Pesticides, October 25,2010) In an effort to control sea lice in farmed Atlantic salmon Health Canada has approved a request by the province of New Brunswick to use the pesticide Alphamax, whose active ingredient is deltamethrin. The high concentrations of salmon in aquaculture facilities has lead to major problems with sea lice, a type of parasitic crustacean that attaches to the fish. Health Canada has approved the use of the restricted pesticide deltamethrin through December of this year. While many salmon farmers are pleased, the decision by Canada’s federal agency has many local fishermen concerned about the effects the pesticide will have on fish and shellfish populations. “Basically we are shocked in a nutshell,” said Grand Manan Fishermen’s Association project manager Melanie Sonnenberg, adding, “Dsappointed doesn’t cover it.” The use of deltamethrin will be restricted to tarped cages or well boats, boats with large holds. Treatment would involve placing fish in the boats, bathing them in Alphamax and releasing them back into cages along with the treated water. The industry is ready to start using the treatment in the Bay of Fundy. Fish farmers have been challenged in controlling sea lice outbreaks this summer, particularly in the upper Passamaquoddy […]

(Beyond Pesticides, September 14, 2010) A new study confirms that indoor uses of consumer products, including pesticides, are the primary sources of indoor exposure to endocrine disruptors —chemicals that disrupt hormones and cause adverse developmental, disease, and reproductive problems— and shows that indoor levels are higher than those outdoors. Researchers from Silent Spring Institute, Columbia University, and the University of California-Berkeley measured airborne concentrations of endocrine disruptors in two California communities: Bolinas, a rural, affluent coastal town, and Richmond, a working-class city ringed by oil refineries. The study is published online in the September 1, 2010 issue of Environmental Science & Technology. The researchers analyzed 104 chemicals in 50 homes, including both chemicals that penetrate indoors from outdoor industrial and transportation sources and those from indoor use of consumer products and building materials. Similar levels of contamination were found inside homes in both communities, but outdoor levels were higher in Richmond. Among the chemicals found were pesticides, phthalates, parabens, PBDE flame retardants, and PCBs. A total of 38 pesticides are evaluated, including banned organochlorines (e.g., DDT, PCP), and current use products such as carbamates (e.g., propoxur), organophosphates (e.g., chlorpyrifos), and pyrethroids (cypermethrin). Thirteen pesticides were detected outdoors and sixteen pesticides […]

(Beyond Pesticides, September 1, 2010) A resurgence of bedbugs across the U.S. has homeowners and apartment dwellers taking desperate measures to eradicate the tenacious bloodsuckers, with some relying on dangerous outdoor pesticides and fly-by-night exterminators. However, these measures pose more dangers than any perceived short-term benefit, as non-toxic alternatives are not widely discussed. Bed bugs can be effectively controlled without the use of dangerous chemical pesticides. Heat treating infected spaces or items such as furniture and laundering linens in hot water will kill bed bugs. Habitat modification, such as sealing cracks, and removing clutter, can prevent an infestation from occurring. Some steps you can take to treat for bed bugs include: ”¢ Eliminate clutter —clutter provides places for bed bugs to hide! Getting rid of as much clutter as possible will help you locate and get rid of infestations. ”¢ Caulk and Seal Crevices to prevent bed bugs from entering your home. ”¢ Encase mattresses and box springs —make sure the encasement has been tested for bed bugs and will not rip and does not contain synthetic pesticides impregnated in the material. If left on, it will eventually kill all bed bugs inside, and will make finding bed bugs on […]

(Beyond Pesticides, July 29, 2010) A set of mandatory rules intended to reduce pesticide use in public and private schools in Indiana is pending approval after voluntary implementation guidelines failed. The Indiana Pesticides Board submitted a draft proposal in June outlining rules to minimize pesticide exposure to students. These measures include banning the use of pesticides when students are present, keeping pesticides locked in storage areas where students do not have access, providing advance notice of pesticide applications, and using pesticides with the lowest hazards to children. Although Beyond Pesticides recommend the additional step of developing a defined Integrated Pest Management (IPM) program, these tactics represent a good first step towards pesticide reduction in schools. The Indiana School Board Association developed a set of voluntary pesticide guidelines in 2001, but while rates of adoption increased, the Indiana state chemist’s office found that some schools were not implementing those policies, or had not adopted pesticide guidelines. It is important that schools adopt a comprehensive pesticide policy because children are especially vulnerable to the health hazards associated with pesticide exposure due to their small size, greater intake of air and food relative to body weight, and developing organ systems. Several pesticides, including […]

(Beyond Pesticides, June 17, 2010) Researchers have found detectable levels of common household pesticides in the majority of umbilical cord blood of babies born at an urban hospital. The study looks at concentrations of organophosphate (OP), carbamate, pyrethroids, and organochlorine pesticides in samples of umbilical cord blood taken from newborns delivered at the Johns Hopkins Hospital Labor and Delivery Suite in Baltimore. Researchers looked at the umbilical cord serum, as opposed to maternal serum, in order to provide a more direct estimate of exposure to the fetus. While human biomonitoring studies have found detectable levels of these pesticide chemicals in urine and blood samples from children and adults in the past, few studies have been carried out in the U.S. evaluating exposure in utero. In addition to tracking pesticide concentrations, researchers also aimed to identify demographic and socioeconomics factors associated with in utero pesticide exposure. Anonymous anthropometric and sociodemographic characteristics of the mothers and infants were collected along with umbilical cord blood that would have otherwise been discarded. Included in the characteristics collected that researchers considered might affect pesticide exposure risk were: age, race, body mass index, parity, education, health insurance, marital status, smoking, area of residence and housing density. […]

(Beyond Pesticides, March 31, 2010) Last week the U.S. Environmental Protection Agency (EPA) announced that it was taking action aimed at improving residential safety and reducing risks associated with bug bombs, or total release foggers (TRFs). The agency is calling for significant changes to product labeling to address the most common causes of exposure incidents associated with TRFs. However, product labels do not adequately protect the public from toxic pesticide ingredients and calls to ban foggers and promote safer alternatives, action that has been urged for years both within and outside the agency, continue to go unheeded. Prompted by concerns raised by a 2009 petition from the New York City Department of Health to reclassify TRFs as restricted use pesticides, EPA sent a letter of notification to manufacturers on March 23, 2010 stating that the agency is now requiring a number of labeling changes by September 30, 2011. In spite of New York’s recommendation, the agency concluded that reclassification is inappropriate and would unnecessarily remove these inexpensive pest control tools from the residential market. Since, according to the agency’s analysis, the largest proportion of incidents is attributable to failure to follow label instructions, the changes are targeted at minimizing those […]

(Beyond Pesticides, March 24, 2010) Due to a significant increase in adverse incidents, the U.S. Environmental Protection Agency (EPA) is taking a series of actions aimed at increasing the safety of spot-on pesticide products for flea and tick control for cats and dogs. EPA will begin reviewing labels to determine which ones will require new instructions and labeling for on-spot flea products. EPA began investigating the products after discovering a sharp rise in the number of dogs and cats reported to be sick. Incidents reported by consumers rose from 28,895 in 2007 to 44,263 in 2008, an increase of 53 percent. The products investigated, including the popular Frontline and Advantage brands, are small vials of liquid pesticides that pet owners apply monthly to the backs of dogs or cats to kill fleas and ticks. EPA began investigating the products after discovering a sharp rise in the number of pets reported to be sick after they were treated. The year long investigation, conducted by a team of veterinarians assembled by the agency, concluded that certain pets — small dogs between 10 and 20 pounds — are most susceptible to the problems, which include rashes, vomiting, diarrhea and seizures. EPA plans to […]

(Beyond Pesticides, March 17, 2009) “Children Act Fast…So Do Poisons” is the message that the U.S. Environmental Protection Agency (EPA) is sending in conjunction with the Poison Prevention Week Council to keep poisonous substances out of the hands of children. In observance of the annual National Poison Prevention Week (March 14-20), EPA recommends locking up household cleaners, disinfectants, solvents and other materials as the best way to reduce accidental poisoning among children. However, Beyond Pesticides advises the public to throw out poisonous chemicals and utilize non-toxic methods of pest management. While it is wise to keep all potentially harmful household products out of the reach and hands of children, Beyond Pesticides recommends to the public to abandon poisonous chemicals and instead practice non-toxic methods of pest management and use least-toxic chemicals where possible. EPA continues to facilitate and apologize for the unnecessary use of highly toxic pesticides, disinfectants, solvents and other hazardous materials that it registers, and misses every year the important opportunity during National Poison Prevention Week to alert families with children about integrated pest management and organic methods that are effective, but not reliant on hazardous methods. Numerous scientific studies that show children carrying a body burden of […]

(Beyond Pesticides, March 10, 2010) A study investigating the sublethal effects of pyrethroids, bifenthrin and deltamethrin on honeybees finds that the chemicals significantly impair the pollinators’ reproduction. The researchers also point out that the concentration of each pesticide that produced adverse effects in the experiments was at or below those that bees could encounter while pollinating treated crop fields. “Effects of sublethal concentrations of bifenthrin and deltamethrin on fecundity, growth, and development of the honeybee Apis mellifera ligustica” published in the March issue of Environmental Toxicology & Chemistry, investigated the effects of the two pesticides at sublethal concentrations on fecundity, growth, and development of honeybees were examined with the feeding method for a three-year period (2006-2008). It was shown that both bifenthrin and deltamethrin significantly reduced bee fecundity, decreased the rate at which bees develop to adulthood, and increased their immature periods. Queens in the control group in 2006 laid a little more than 1,200 eggs each day, compared to not quite 900 a day in the bifenthrin group and roughly 600 per day in the deltamethrin group. In general, the hatch rate of pyrethroid-exposed eggs was also significantly depressed. The success rate of hatchlings, that is the share that […]

(Beyond Pesticides, February 18, 2010) Hundreds of dead and dying lobsters just north of the Gulf of Maine were found to have been exposed to cypermethrin, a highly toxic synthetic pyrethroid pesticide registered for agricultural and residential use that some officials think may have been illegally used in fish farming. However, the chemical, which is primarily used for indoor insect control and termites, is extremely toxic to fish and aquatic organisms and part of a family of pesticides (synthetic pyrethroids) that is increasingly showing up in water bodies at toxic levels, a cause for concern according to scientists. Area fisherman are angry and concerned, however investigators are not yet certain just how this pesticide wound up in the Bay of Fundy, which is located between the Canadian provinces of Nova Scotia and New Brunswick. The first dead lobsters were discovered last fall in Grand Manan’s Seal Cove, and only a few days later fisherman found dead lobsters in two different locations in the Bay, including about 816 kilograms of dying or dead lobsters in Deer Island’s Fairhaven Harbour. This prompted an investigation by Environment Canada that began on December 22, 2009. The department looked at samples of crab, kelp, mussels […]

(Beyond Pesticides, February 16, 2010) Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals, according to a study by researchers at the University of California, Berkeley, and Southern Illinois University (SIU). The study, “Urban and Agricultural Sources of Pyrethroid Insecticides to the Sacramento-San Joaquin Delta of California,” in the journal Environmental Science & Technology, is the first published work to document toxic levels in the water column as well as in the sediments at the bottom of streams. Pyrethroid insecticides, commonly used to kill ants and other insects around the home, have been found in street runoff and in the outflow from sewage treatment plants in the Sacramento, California area. The insecticide ended up in two urban creeks, the San Joaquin River and a 20-mile stretch of the American River, traditionally considered to be one of the cleanest rivers in the region. Although the pyrethroid levels were low, around 10-20 parts per trillion, they were high enough to kill a test organism similar to a small shrimp that is used to assess water safety. “These indicator organisms are ‘lab […]

(Beyond Pesticides, December 16, 2009) The U.S. Centers for Disease Control and Prevention (CDC) has published its Fourth National Report on Human Exposure to Environmental Chemicals – the most comprehensive assessment to date of the exposure of the U.S. population to chemicals in our environment. CDC measures 212 chemicals in people’s blood or urine – 75 of which have been measured for the first time in the U.S. population. One of the new chemicals included in this report is triclosan, a common and hazardous antibacterial agent. In this Fourth Report, 75 new chemicals were added. Chemicals in the Fourth Report include metals such as lead, cadmium, uranium, mercury, and speciated forms of arsenic; environmental phenols such as bisphenol-A (BPA); acrylamide; perfluorinated chemicals; polybrominated diphenyl ethers (PBDEs); polychlorinated biphenyls (PCBs); volatile organic compounds such as benzene, styrene and methyl tert-butyl ether; pesticides; phthalates; and dioxins, furans and related chemicals. The data analyzed in the Fourth Report are based on blood and urine samples that were collected from approximately 2400 people who participated in CDC’s National Health and Nutrition Examination Survey (NHANES) from 2003 through 2004. NHANES is an ongoing national health survey of the non-institutionalized U.S. population that includes collecting and […]

(Beyond Pesticides, November 13, 2009) The Ohio Department of Agriculture is asking the U.S. Environmental Protection Agency (EPA) to allow an unregistered use of the neurotoxic and cancer causing insecticide propoxur in homes to fight bedbugs in what state officials are describing as an ”˜emergency’ situation. The chemical, o-isopropoxyphenyl methylcarbamate, is in the carbamate family and classified as a probable human carcinogen (Group B2) by EPA, and listed as a known human carcinogen by the state of California. Though EPA allows emergency exemptions for unregistered pesticide uses in agriculture and for public health reasons under a controversial waiver program (Section 18, Federal Insecticide, Fungicide and Rodenticide Act, 40 CFR Part 166), it rarely issues such an exemption for an indoor pesticide use. Columbus, Cleveland, and Cincinnati are all experiencing a surge of bed bug infestations. According to Richard Pollack, a Harvard University public health entomologist, this is probably due to the fact that bedbugs are becoming resistant to many pesticide products that are used today. The use of broad spectrum insecticides, which kill common household insects such as cockroaches, ants and other insects including bed bugs, has resulted in insect resistance to these chemicals. Many of the chemicals used against […]

(Beyond Pesticides, November 6, 2009) A 10-month old boy died in Williamston, SC after his mother used several insecticide foggers, also known as “bug bombs” inside their home. Elizabeth Whitfield called 911 when her 10-month old son, Jacob Joesup Isiah Leah Whitfield, was having difficulty breathing. She and her older son Kenneth were also experiencing breathing problems. According to Beyond Pesticides, every death and injury caused by foggers must be attributed to a the failure of EPA’s regulatory system to take an unnecessary and ineffective product off the market. The group says that EPA has known for years that foggers kill people and present a serious public health hazard, regardless of warnings on the product label, and can be replaced by safe alternative products and practices. “This child’s death should move the leadership of EPA to take the necessary steps to ban foggers, an action that has been urged for years both within and outside the agency,” said Jay Feldman, executive director of Beyond Pesticies. Anderson County Deputy Coroner Don McCown said, “It appears mom has been using a pesticide fogger in the house that may have contributed to their illnesses.” Ms. Whitfield had been in the house, a rental […]

(Beyond Pesticides, August 21, 2009) Pesticide use around our homes are an underestimated source of water pollution – leading to more than 50 percent more water pollution than previously believed, according to scientists looking at pesticide use in residential areas in California. The polluted runoff has been linked to fish kills and loss of aquatic species diversity. The findings of a new study were reported earlier this week at the 238th National Meeting of the American Chemical Society in Washington, DC. In the study, Lorence Oki, from the Department of Environmental Horticulture at the University of California Davis, Darren Haver, with University of California Cooperative Extension, and their colleagues explain that runoff results from rainfall and watering of lawns and gardens, which winds up in municipal storm drains. The runoff washes fertilizers, pesticides and other contaminants into storm drains, and they eventually appear in rivers, lakes and other bodies of water. “Results from our sampling and monitoring study revealed high detection frequencies of pollutants such as pesticides and pathogen indicators at all sites,” Mr. Oki said of their study of eight residential areas in Sacramento and Orange Counties in California. Preliminary results of the study suggest that current models may […]

(Beyond Pesticides, July 17, 2009) High levels of pyrethroid pesticides in the Sacramento-San Joaquin River Delta, the number one river system on America’s Most Endangered Rivers List of 2009, has been linked to heavy urbanization in the region. Leading a study to understand the collapse of the delta’s ecosystem, University of California-Berkeley toxicologist Donald Weston, Ph.D. found that these pesticides most likely reached the river from urban storm drains, collecting household pesticide disposal and runoff from lawns of 1.4 million residents in the Sacramento region. Five years ago, a study by Dr. Weston and his colleague Michael J. Lydy, Ph.D of Southern Illinois University in Carbondale found that synthetic phyrethroids were collecting in river and creek sediments at levels that are toxic to bottom dwelling fish. Current research holds that there are enough pyrethroids to kill tiny shrimp, which are said to be the first link in the aquatic food chain. Pyrethroids are synthetic versions of pyrethrin, a natural insecticide found in certain species of chrysanthemum. It initially came on the market as a ”˜safer’ alternative to the heavily regulated and highly toxic organophosphates, such as diazinon and chlorypyrifos. Despite the fact that there are plenty of effective pest control […]

(Beyond Pesticides, June 17, 2009) A new study finds that toxic pesticides, including those already banned, persist in homes. The study’s results indicate that most floors in occupied homes in the U.S. have measurable levels of insecticides that serve as sources of exposure to home dwellers. These persistent residues continue to expose people, especially vulnerable children, to the health risks associated with these chemicals. Published in Environmental Science and Technology, the study, entitled “American Healthy Homes Survey: A National Study of Residential Pesticides Measured from Floor Wipes,” was conducted as a collaboration between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Housing and Urban Development. Five hundred randomly selected homes were sampled using alcohol wipes to collect dust from hard surface floors, mostly kitchen floor surfaces. The swipes were analyzed for 24 currently and previously use residential insecticides in the organochlorine, organophosphate, pyrethroid and phenylpyrazole classes, and the insecticide synergist piperonyl butoxide. Researchers found that currently used pyrethroid pesticides were, not surprisingly, at the highest levels with varied concentrations. Fipronil and permethrin, both currently used, were found in 40 percent and 89 percent of homes respectively. However, the researchers found that long discontinued pesticides like DDT and […]

(Beyond Pesticides, May 6, 2009) The U.S. Environmental Protection Agency (EPA), in consultation with the U.S. Fish and Wildlife Service (USFWS), is imposing use restrictions for the insecticide methoxyfenozide on cranberries in Wisconsin because of its potential effect on the Karner Blue butterfly. The Karner Blue butterfly is a federally listed endangered species. It remains to be seen whether, short of a ban, the complex and difficult to enforce restrictions on use and application methods will adequately protect the endangered species. The limitations for methoxyfenozide are contained in a series of county-specific Endangered Species Protection Bulletins (Bulletins) as part of EPA’s Endangered Species Protection Program (ESPP). EPA entered into consultation with USFWS after determining that use of methoxyfenozide on cranberries in Wisconsin may affect the listed Karner Blue butterfly. USFWS recommended a number of use limitations that, when implemented, should result in use that is not likely to adversely affect the Karner Blue butterfly, according to the bulletin. Limitations include not applying the pesticide within the designated pesticide use limitation area, ground applications- only which must be made using a drift retardant and nozzles, and when the wind speed is between 2-10 mph. These limitations are effective within specific areas […]

(Beyond Pesticides, April 16, 2009) The U.S. Environmental Protection Agency (EPA) convened the first ever National Bed Bug Summit (April 14-15, 2009) to solicit recommendations from scientists, state and local officials, pest control operators and the general public on how to tackle the resurgence of the blood sucking insects. Bed bugs have rebounded in significant numbers for the first time since World War II, partly due to increased global travel and their increasing resistance to commonly used pesticides. Bed bug outbreaks have tripled since 2005, according to a survey of 800 pest control firms across the country, infesting apartment buildings, college dormitories, hospital wings, homeless shelters and top-rated hotels. Bedbugs outbreaks have been reported in at least 27 states, including Honolulu, San Francisco, Cincinnati, Chicago, Houston and Miami. In 2006, a Chicago woman sued a New York hotel for $20 million after suffering more than 500 bed bug bites. Persistent outbreaks are normally concentrated in low-income neighborhoods, where people cannot afford to replace or professionally clean bedding and soft furnishing. Both New York and San Francisco have passed city legislation to help control the spread of the bugs. In San Francisco, the legislation centers on landlord and tenant rights while […]

(Beyond Pesticides, February 23, 2009) Permethrin and lindane metabolites are found in children who use lice shampoos containing the insecticides, according to researchers affiliated with the Centers for Disease Control and Prevention. The study, “Pesticide exposure resulting from treatment of lice infestations in school-aged children in Georgia,” published in the February issue of the journal Environment International, is the first to measure children’s exposure to chemical lice treatments. The researchers collected baseline urine samples from 78 enrolled children between the ages of six to ten years of age. About one-third of those children were diagnosed with head lice and subsequently treated with at least one over-the-counter permethrin lice treatment, a prescription lindane treatment, or both. Within seven days of the insecticide application, urine samples were again collected. The permethrin exposed children had significantly higher urinary pryrethoid metabolite levels in their post-exposure urine samples. Lindane metabolites were also elevated in urine samples after treatment. Interestingly, the study states, “Exposed participants appeared to have higher pre-exposure metabolite levels — likely from multiple treatments before enrollment — than unexposed participants.” Pentachlorophenol, a metabolite of lindane, was significantly higher in the urine of those children who used a lice treatment regardless of whether it […]

(Beyond Pesticides, December 22, 2008) The U.S. EPA has filed an administrative complaint, seeking a maximum penalty of only $4,550, against a pest control company that sprayed pesticides in a couple’s home, causing the wife to die shortly thereafter. It has been more than three years since the incident took place in Florence, Oregon. Swanson’s Pest Management of Eugene, Oregon sent an employee to a home on June 29, 2005 to apply Conquer Residential Insecticide Concentrate, active ingredient esfenvalerate, and ULD BP-100 Contact Insecticide, active ingredient pyrethrin. The couple returned to their home two and a half hours later and immediately fell to the ground due to the fumes. Paramedics were called in and they too experienced respiratory distress or became ill when they entered the treated home. According to The Oregonian, Florence Kolbeck was 76 years old and died of cardiac arrest as a result of the exposure. Her husband, Fred, was hospitalized for respiratory distress. The complaint was filed following a review of Swanson’s use of the two pesticides, finding that the company failed to properly ventilate the home prior to the occupants re-entering, and improperly applied Conquer as a “space spray” at nearly three times the allowable […]

(Beyond Pesticides, December 16, 2008) According to a new study, published in the December 2008 issue of Environmental Health Perspectives by researchers at Columbia University’s Mailman School of Public Health, pregnant women continue to be exposed to pesticides in the home. In fact, 75% of the sampled homes of pregnant women in inner-city New York are contaminated with piperonyl butoxide (PBO), a pesticide synergist linked to cancer and other health problems. Following the Environmental Protection Agency’s phase-out agreements with the manufacturers of organophosphate insecticides chlorpyrifos and diazinon in 2000 and 2001, the Columbia University researchers sought to determine the impact of the new regulations on pest infestation levels, pesticide use, and pesticides measured in indoor air samples. They enrolled 511 pregnant women from inner-city New York between 2000 and 2006. Permethrin, a pyrethroid insecticide; PBO, a pyrethroid synergist; chlorpyrifos; and diazinon were measured in 48-hr prenatal personal air samples. Data on pest infestation and pesticide use were collected via questionnaire. 88% of women report using pesticides during pregnancy and 55% report using higher-exposure pesticide applications (spray cans, pest bombs and/or professional pesticide applicators). Self-reported pest sightings and use of higher-exposure applications increased significantly after the regulations were implemented. PBO, cis-, […]
