Overview
Small enough for any outlet, quiet enough for the bedroom.
SDH-057 plugs straight into a wall outlet and starts working at once. Its chip sweeps automatically through 22–65 kHz, switching frequencies so pests do not adapt to a single tone. The ultrasound is silent to people, and the unit draws 3 W or less.
Two blue LED strips at the top and bottom act as a soft night light. Press the button on the right side to switch them on or off; the ultrasound keeps running either way. One unit covers about 80–100 m² in an open room. Ultrasound does not pass through walls, so use one unit per room.
Highlights
Simple to use, built for every room.
Light
Dual night lights
Two blue LED strips with their own side switch; ultrasound keeps working with the lights off.
Size
Compact
88 × 60 × 52 mm, about 75 g, so it fits behind furniture and next to other plugs.

FAQ
Questions buyers ask about SDH-057
Can people or pets hear it?
The 22–65 kHz ultrasound is silent to people. Keep pet rodents such as hamsters and guinea pigs away from the room where it runs.
Does it work with the night light off?
Yes. The side button only switches the two blue LED strips; the ultrasound keeps running.
How large an area does one unit cover?
About 80–100 m² in an open room. Walls, doors and large furniture block ultrasound, so use one unit per room.
How long until it works?
Keep it plugged in continuously. Pests can seem more active in the first days as they leave hiding places; activity usually drops over the following weeks.
Which plug types are available?
US, EU and UK plug versions, confirmed with each order.
Which certifications does it have?
CE (EN 60335-1) and FCC SDoC. Our establishment is registered with the U.S. EPA under Est. 97987-CHN-1.
