"I discovered the Evictor through AsktheExterminator.com. The Evictor does exactly what the ad says. I used the Evictor to evict squirrels in the ceiling crawl space of our house. Within a few minutes after installing the Evictor I heard them scrambling around. Within a day it sounded like they had vacated. I left the Evictor running for a month as recommended and checked the crawl space. No signs of the squirrels. I covered the inside of the gable vents where they entered with wire mesh and have not had any return. Thanks for a great product that delivers what it promises."
