Anticoagulant Rodenticides: Bad for Pets and Wildlife

National Park Service scientists have conducted studies on wildlife habitat in the Santa Monica Mountains revealing a connection between the deaths of wildlife and their exposure to anticoagulants rodenticides (commonly referred to as rat poison) Depending on the species, 80%-90% of bobcats, coyotes, mountain lions and raptors tested positive for being poisoned.  As a result, cities adjacent to the Santa Monica Mountains have been requested to discourage the use of anticoagulant rodenticides.

On March 8, 2017, the Camarillo City Council adopted a Resolution urging businesses in Camarillo to no longer sell or use anticoagulant rodent poisons, urging all property owners to cease purchasing or using the poisons on their properties in Camarillo and committing the City of Camarillo to discontinue using the poisons as part of its maintenance program for city-owned parks and facilities.

Throughout California, the use of poison baits containing anticoagulants has harmed and killed numerous wild animals and pets. This is because predatory and scavenging birds and mammals like owls, hawks, raccoons, foxes, skunks, coyotes, bobcats and mountain lions eat dead or dying rodents that have consumed these baits and will, in turn, be poisoned. Pets may also consume infected carcasses or dying rodents, as well as unprotected bait directly. Even children may be harmed by unprotected poison baits.

Strategies to eliminate rodents include removing habitat such as ivy and wood piles and food sources such as exposed garbage and pet food. Other alternatives such as traps, natural repellants, and barn owl nesting boxes are efficient rodent control. Please stop using anticoagulant rodent poisons now and properly dispose of any such poison(s) you may still have on hand. Call the City’s household hazardous waste facility at (805) 987-0717 for an appointment to drop off rat poison(s). For more information, please visit
