Pest Contro™ brand Ultrasonic devices use ultra-high frequency sound waves that are set within the hearing range of rodents and other common household pests. Inaudible to humans, cats, dogs and most other household pets, the Ultrasonic frequency sounds like an extremely loud siren to rodents, driving them from the protected area. The Lentek PestContro 500 is designed to provide ultrasonic covereage within a single room. The PR30-3 contains three individual PestContro 500 units, allowing you to place multiple units in selected areas of your home or office.

Simply plug the PestContro 500 device into an unobstructed wall outlet in the room to be covered by ultrasonic sound power. Coverage in a room can be improved by bouncing the sound off reflecting objects such as walls, mirrors, cupboard doors, appliances, etc. Obtaining a ricochet pattern will increase effective coverage. It is important to note that ultrasound cannot transmit through walls and doors, so you can keep the ultrasonic coverage within a room by closing doors, or leave the doors open to potentially extend the protection outside the room where it is plugged in.There will be a stronger ultrasonic effect within the room where the unit is placed.
