We've had vole problems for several years and a very large yard. I spread these ultrasonic repellents throughout about 3/4 of an acre. I didn't realize that the buzzing it emits is audible (I presumed it was a silent, underground ultrasonic buzz). At first it was a bit annoying, but you actually get quite used to it. I believe they are working because we have NO MORE vole tracks through the lawn! I think we also had a mole (a new addition -- yay) and I'm not 100% sure it worked for the mole. I may have to gas him out....
