Have one of those in our office. We get squirrels in the attic. Actually worked! Never considered it until you just mentioned it now.. Will be picking one upIf you battle the never ending problem of mice and or rats again let me emphasize the fact about getting rid of these rodents on your property for good. We have used ultrasonic pest repellent sound machines on our farm for years now. We started using them in the mid 1980's to help protect our corn which we had stored in silos for cattle. At that time we had about six of these sound machines arranged at various locations around the barns and they really do get the job done. Once we had them set up within the first few weeks we noticed fewer and fewer mice running around. Within a month we were free of these pests. The machine omits an ultrasonic sound at 26-74Khz at 105 decibels from the built in speaker and cannot be heard by the human ear or larger animals like chickens, etc. It works for mice, rats, bats, cockroaches, spiders. If you have rabbits you will not want the machines close to them. The machines do the job! The ones we purchased lasted for years.
