Rat Poison Kills a Pack of Eastern Coyotes, Canis latrans, in an Urban Area

Jonathan G. Way, Stephen M. Cifuni, David L. Eatough, Eric G. Strauss


We document the death of a pack of Eastern Coyotes (Canis latrans) from high levels of brodifacoum, a second generation poison that is the active ingredient in some forms of rat poison (e.g., d-Con®). The Coyotes died within a week of each other during late March/early April 2005. This incident indicates the vulnerability of wild animals to commercial over-the-counter rodenticides.
