I used to have a fish pond in the back yard. Neighbors have a HUGE one with koi in it. Raccoons are all over the place, fishing. They ate most of my gold fish, too. So....I started peeing around it every once in awhile. MY turf! Keep away! And it worked. Raccoons even used to run all around the roof of my house..either playing or bickering with each other. Now that Mr. Gracie and the roomie pee on the fences every now and then, that has stopped. Haven't seen or heard one in almost 2 years now...except next door fishing in their pond for juicy Koi.
