A group called Save Lincoln Wildlife is seeking to ban the use of anticoagulant rodenticides (ARs) in Lincoln, saying the chemicals are harming raptors and other animals that eat rodents who have ARs in their systems.
Their citizen’s petition for the March 28 Annual Town Meeting asks voters to approve a home rule petition that would authorize the Select Board to ask the legislature to allow the town to ban the use of ARs. The town can’t do so without this step since pesticides are regulated by the state.
When rodents eat trap bait containing ARs, they usually don’t die right away, and the chemical — which prevents blood from clotting, leading to uncontrolled bleeding and death — builds up in the systems of predators including coyotes, hawks, and other birds that eat those rodents and can eventually cause their deaths as well, Trish O’Hagen of Save Lincoln Wildlife told the Select Board on Feb. 9.
“I can’t help but think back to the 1960s when there were only 500 bald eagles left in the country” due to widespread use of the insecticide DDT, which severely weakened eagle eggshells, leading them to break under the weight of parents during incubation.
Mice, rats and other pests are attracted to food in compost piles and garbage cans, and raptors are the best way to control them naturally — “and it’s sort of ironic,” O’Hagen said, since raptors are the ones being harmed by ARs in their prey.
According to Mass Audubon, the federal government banned the retail sale of second-generation ARs in 2015 due to the dangers posed to children, pets, and wildlife, but they remain legal and widely used by licensed pest control professionals in Massachusetts, so “homeowners really need to know the specific questions to ask” of exterminators, O’Hagen said.
A number of other towns have banned the use of ARs on town-owned property (Lincoln doesn’t use the chemicals but has no formal ban). Cities and towns including Arlington, Billerica, Brookline, Concord, Lexington and Newton are also seeking legislative approval to ban the use of ARs on private property.
Donelan’s and Lincoln Woods have both switched from ARs to other types of rodenticide, said O’Hagen. The best methods to pest control are rodent-proof containers, blocking entry holes, and using snap traps or contraceptive rodent treatments, she added.
