How To Kill A Possum In Your Yard. Using traps are the easiest way to get rid of them and you can use the traps. Opossums hunt, kill, and eat mice, rats, and snakes (including poisonous ones).
While choosing a trap, opt for a live capture one. These little animals usually come out at night looking for food and if your dog has free access to the yard they might hunt them down. If it looks like an animal dug its way into the yard, it is likely not an opossum.
Please contact your municipality to see if you are allowed to kill a possum in your yard before using this method.
Opossums are scavengers and clean up dead animal carcasses. Add a rag to the ammonia and place one end up and cut a small hole for the scent to diffuse. Never kill baby opossums if you come across them in your yard. Remove areas of standing water on your property.
