Is there a safe way to repel raccoons? Moth balls maybe? We have a local golf course that has a raccoon creating a den out of the pump house. This building is maybe 10 x 10 that is about 5 feet below ground. The heaters have been on all winter to prevent the pump from freezing because the building is not very weather proof, it is just a shack. There is not a problem with having the critter around the course, but there is a problem when trying to turn on the pump. Being in a small space with a wild animal is not my idea of fun. If anyone knows of a non-lethal way of keeping him away I would appreciate it.
