Does anyone have any information on the bug repellants that emit a high-pitched sound? These are the type that are supposed to keep the offending insects, rodents, etc. from entering the area as opposed to killing them. I have heard that ferrets are bothered by the sound but was wondering if anyone had tried one and what they thought or how their ferrets reacted to it. This problem is more for ants, beetles and spiders as opposed to fleas. Any information you could give me would be greatly appreciated. Thank you!
