Yes. The most effective rodent control program uses exclusion techniques (sealing the places where rodents enter your home) and sanitation (removing plants and objects that attract rodents and potential habitat such as ivy or wood piles); animal removal is used only when necessary. More information on controlling mice, rats and field rodents is provided on the
University of California Integrated Pest Management website.
Second generation anticoagulant rodenticide products contain the active ingredients brodifacoum, bromadiolone, difethialone and difenacoum. These products cannot be legally purchased or held by the general public and can only be applied by certified pesticide applicators. These chemicals prevent the clotting of blood in animals that have ingested it causing internal hemorrhaging and death. Animals (including humans, pets and non-target wildlife) that eat the chemical or eat rodents that have eaten the chemical will become sick and die.
Throughout California, the use of poison baits to control rodents has injured and killed hundreds or thousands of wild animals and pets. Predatory and scavenging birds and mammals like owls, hawks, raccoons, bobcats, mountain lions, foxes, skunks and coyotes that eat dead or dying rodents that have consumed these baits will also be poisoned. Pets will also eat dead or dying rodents and unprotected bait. More information on rodenticides.
