Electronic Pest Repellents
Using an electronic repellent device is one of the easiest and safest ways to keep rodents out of any structure. Electronic repellents work by emitting sound waves that are inaudible to human ears but drive mice insane.
Even better, many models repel other pests such as spiders, roaches, and small insects. They are simple to set up; simply plug them into an outlet and they are ready to use!
