State Allows Experiments to Steer Coyotes From Pets

A Cal State San Bernardino professor has received state approval to conduct experiments using lithium chloride on coyotes as a deterrent to control attacks on pets in Villa Park.

The Department of Pesticide Regulation, a department under the state Environmental Protection Agency, recently granted the approval to behavioral psychologist Stuart R. Ellins for the food aversion experiments, according to an agency spokeswoman.

In his application, Ellins proposes to lace animal carcasses with lithium chloride that, if eaten by the coyote, at most will cause nausea and vomiting. Officials have theorized that if coyotes become sickened from eating the laced food, they might stop attacking pets and hunt for food in their own habitat.

City Manager Fred Maley said the city has not been notified by Ellins or the state agency about the approval. “My direction is to go forward when [Ellins] is in a position to do so,” Maley said.

Residents have long complained of coyote attacks on pets, sparking heated debate about control measures. Residents have signed petitions opposing the trapping or killing of coyotes, while others have called on a divided City Council to take swift action.

Ellins would perform his experiment at no cost to the city. But Maley said the city would reimburse him for expenses, such as mileage.
