(Beyond Pesticides, May 10, 2018) Rodenticides like bromadiolone, used to kill vole populations on farms, act like “super-predators” that imperil ecosystem health, according to preliminary results published by researchers working for the European Union. “Controlling voles with bromadiolone reduces the amount of food available to predators and increases their risk of secondary poisoning when they eat the contaminated rodents,” project researcher Javier Fernandez de Simon, PhD, said in a press release. The study provides a model that may alleviate the impact of rodenticide use and provide a balance between on-farm pest management and sustainability. There are several types of rodenticides available on the market, including acute poisons like strychnine, fumigants like phosphine gas, and anti-coagulants such as warfarin and bromadiolone. Anti-coagulants, the focus of the present study, work by blocking the ability of the body to form blood clots. Animals exposed to bromodialone and other anti-coagulants experience ruptured blood vessels, hair loss and skin damage, nosebleeds, and bleeding gums prior to death. These pesticides are generally applied through secured bait boxes that only allow rodent pests to feed, however secondary poisoning is a common occurrence, leading researchers to dub these rodenticides, in effect, as “super-predators.” Rodents that ingest anti-coagulant pesticides […]

(Beyond Pesticides, February 27, 2017) Texas has been dealing with a feral hog issue for many years, however recently Texas Agriculture Commissioner Sid Miller approved the use of a toxic rodenticide in an effort to control feral hog populations, a decision hunters and trappers oppose because the pesticide will poison prey and wreak havoc on ecosystems where the hogs live. The estimated population of the feral hog population is about 1.5 million in the state of Texas, where they can cause extensive damage to property, crops, and native wildlife. Wild hogs have been considered to be one of the most destructive invasive species in the U.S. The feral hog population, close to six million, span 39 states and four Canadian provinces. Commissioner Miller, in announcing the widespread use of toxic pesticide referred to the problem as the “feral hog apocalypse.” Damage caused by wild hogs has been estimated to reach well into the millions. Smithsonian Magazine has reported the annual damage caused by feral hog populations to be around $400 million. The Texas Parks and Wildlife website states that hogs are opportunistic omnivores. Feral hogs enjoy eating domestic agricultural crops, such as corn, soybeans, peanuts, potatoes, watermelons and cantaloupe. They can cause […]
