The Oregon Department of Fish and Wildlife has a warning for people who use rodent poison. Recently, veterinarians have seen other animals dying as a result of the poison, whether they are eating it themselves or eating animals that have been contaminated. One veterinarian, Julia Burco, says they’ve been seeing this a lot in owls, hawks, and even in bobcats. It’s also a problem in urban areas. Rat poison can unintentionally harm pets, raccoons, coyotes, even children.
Burco says if you do have a rat or rodent problem, try other methods instead. She suggests traps, or simply blocking the holes that rats and squirrels can squeeze through to get into your house. If you must use bait, follow all directions.
