Bell & Howell Ultrasonic Pest Repeller 4 Pack

Four-Pack Indoor Pest Repeller

The Bell & Howell ultrasonic pest repeller comes in a four-unit kit designed for homeowners and renters who want a chemical-free way to deter mice, rats, spiders, ants and roaches from indoor spaces. Each plug-in device suits households with children and pets because it uses no poisons, traps or odours. It targets common intruders without calling an exterminator.

Plug-In Operation and Coverage

Every unit plugs directly into a standard wall socket so no wiring, batteries or extra hardware are required. The four-pack lets you place devices in several rooms at once, freeing you from moving a single unit around. Because the units are silent and odourless they can stay plugged in continuously without disrupting daily life or needing refills or maintenance.

Variable Ultrasonic Output

Intelligent variable technology shifts the ultrasonic wavelengths constantly so pests do not become immune to the sound. The frequencies remain inaudible to people and pets while staying irritating to rodents and insects over long periods. This continuous, changing output keeps working day and night without the diminishing returns that fixed-frequency devices can suffer.
