"They were recommended by my niece who had rats in her home at one time. We used a pest control company and two, whole house, Pestbye Advanced Rat Repellents. We put one in the roof, where they were and one downstairs and we have not heard from them since and we hope they are gone. We have a broken drain pipe and this is where they got in and once this is mended all should be well but we intend to leave one on in the house, as we back on to fields, all the time."
