"Had been pestered by field mice and rats in the wall cavities and attic for several months. Poisons and traps had limited success as there always seemed to be replacement rodents scratching and digging no matter how many we despatched.
Plugged in this repellent and rodent problem disappeared. That was over one week ago. On two occasions since, we have heard rodents enter the wall cavity but leave again within seconds."
