Trapping works, but everything said in posts rings true. Fox urine is least expensive/safest to try first.Try your local nursery/garden center. Fox urine is sold in small bottles, and you can purchase very small containers to go with it that are filled with absorbent material. You put the fox urine in the small containers, and hang them at distances of 30' apart in your yard. They can be hung in a tree, or close to the ground on the branches of bushes, etc. Tricks the critters into thinking there's a predator nearby. You just have to refresh the scent as directed on the bottle.
