Do Ultrasonic Pest Repellers Work Against Mice and Rats?
Short answer
Research and field experience show ultrasonic repellers do not reliably stop mice or rats. Rodents get used to the sound, and sound does not travel well through walls and clutter. Sealing, trapping and sanitation work better.
Why they fail
- Rodents habituate to the sound
- Sound is blocked by furniture and walls
- The devices do not remove food or entry points
- Results are inconsistent in tests
What works
Seal entry points with steel wool and metal mesh, remove food and nesting sites and use traps or stations.
When to call
If you hear noises or find droppings despite a repeller, call for an inspection.
What this means in Omaha
Omaha homeowners often try repellers before calling for help, and the delay lets populations grow.
