Ultrasonic Pest Repellent

Pic isn’t loading...is it for rodents?

I had some rodents in my attic and considered the ultrasonic route...ended up going nuclear with the poison instead....put so much poison up there that I turned my attic into a Superfund site, but no more rodents in the attic.

Not sure about this brand but some brands bother children who can still hear high pitched noises. When I was a kid I couldn't stay in a tv showroom for long because of the noise (something the salesmen probably liked!). Now I hear that noise in my ears all the time.
