re: Possum in my Backyard

You don't need to do anything. No significant disease issues. Possums are typically "immune" from rabies due to a lower body temp.

There is probably a possum in your yard multiple days each week.

They are fairly benign critters. Other than eating cat/dog food they don't really do anything. Just wander around looking for food, a mate and trying to not become food.

As creepy looking as they are, they aren't dangerous and rarely do anything other than try to escape. I've caught many young ones with my bare hands.
