No, The bait we place outside around businesses and homes is enclosed inside plastic bait stations and staked to the ground. These stations are used to keep any pets and larger animals from gaining access to the bait inside. On occasion, smaller-sized squirrels and chipmunks may get inside. The mice that eat the bait and die off in nature only ate enough bait to kill a mouse. If another scavenging animal finds the dead mouse that animal would be consuming the same amount of bait which would not be enough to kill anything larger than a mouse. These predator animals also hunt throughout a large territory that expands much farther out than just your house. Your house alone will make up a very small percentage of their overall diet if any at all. Most predator animals would prefer to eat a living animal rather than a cold decomposing mouse carcass.
