In an age of instant information I find it amazing and interesting that the old wives tales about repellents still persist. Google mice eating soap and watch mice eat various brands of soap on video. Same with dryer sheets which they use for bedding, they do not eat moth balls but will play with them, on and on ad nauseum.
HOneywell was sued and lost for their electronic repellers which do not work. So now they come on the market under various names, then go out of business and come back under another name!
I feed the neighborhood cats under my RV and do not have mice or squirrels. It is because I feed the cats there or I just do not have mice and squirrels?
