Question
Raccoons are using my backporch as a bathroom. There is absolutely no food source.  Every morning I clean up their mess.  I have tried moth balls, coyote urine , amonia, hot pepper. Help!!!!

Answer
Water can be a big attraction for raccoon. Even an air conditioner drain.

This is what I make and use to keep raccoon away.

Raccoon can carry a very deadly roundworm to which there is no cure. Be careful cleaning up after them.
