Relocate it at least 25 miles from your home. Conservation land is best. You can call the department of conservation and ask them. Putting it down is an easy fix, but they are good for the eco system. Plus I've never seen an opossum hunt, preferring small rodents (mice not rats), eggs, and insects. With carrion being at the top of the list and only being surpassed by human food found in trashcans. Overall they look grouse so people think the worse of them. Not saying that they won't hunt but it's a simple choice of takeout over cooking at home. They will, more often then not, go for easy food.
Don't get scratched or bit. And wash your hands really really well afterwards.
