Wouldn’t it be great if all you had to do to get rid of household pests was plug in a $10 device and wait? No need for spraying toxic pesticides or setting up poison traps to drive nuisance animal and insect pests out of your home or garden. This is the appeal of using one of the many ultrasonic pest repellers that have invaded the market over the past decades.

“Turn your home’s wiring into a pest repellent force field. Patented digital technology repels rodents, roaches, ants & spiders.” This is the claim of one popular manufacturer selling electromagnetic and ultrasonic pest control products said to eliminate pests from homes and other structures in 2 to 4 weeks by “sending a pulsating signal through or altering the field around the electrical wiring inside homes and other buildings”.
