Some home remedies for getting rid of possums are catching the possums with a traditional animal trap or placing mothballs or ammonia where the possums live. It also helps to get rid of leaves, debris or stray equipment in the yard so that possums do not have a shelter.
A way to get rid of possums is make sure the possums do not have access to a food source, such as bird seed or dog and cat food. Screens or fencing can prevent possums from finding shelter in cracks or underneath a porch. Motion-activated sprinklers, garlic and dog and cat hair also act as a natural repellent to possums.
