OWLTRA URRL01 Ultrasonic Rodent Repeller 4 Pack White

Four-pack coverage for medium rooms

The OWLTRA URRL01 pack contains four plug-in ultrasonic repellers designed for indoor use. Each unit targets rodents in a medium-sized room by emitting high-frequency sound that is inaudible to humans and non-rodent pets. The devices are non-toxic and require no assembly, making them a poison-free option for households with children or animals. Simply insert each repeller into a standard AC wall outlet to begin operation.

Effective range limited by solid barriers

One repeller covers a single medium room, so the four-pack suits a typical home with several affected areas. Ultrasonic waves cannot pass through walls or solid objects, meaning coverage stops at each doorway or partition. For larger infestations the manufacturer advises combining the units with traps or baits. The built-in night light on each device confirms it is powered and running.

Compact white plastic housings

Each repeller measures 1.89 by 3.74 by 3.07 inches and weighs 0.249165 pounds, so it sits unobtrusively in a wall socket. The white plastic casing blends with most décor and the unit draws power directly from the mains with no batteries required. Because sound cannot penetrate hard surfaces, the instructions recommend keeping the front of each device clear of furniture or curtains for best performance.
