I will testify that the radio works for racoons. We had one in the chimney. DH put talk radio real loud right next to where he saw the coon. After the coon left he put a topper on the chimney. It is one thing to evict the critter and another thing to let the critter come back. SIL saw a skunk in the chicken house last spring and went after it with a board - well the skunk was too quick - but SIL did get the skunk... SIL's coat went in the burn pile...
