No, ultrasonic pest repellers are generally not effective at repelling or eliminating cockroaches. While these devices may claim to emit high-frequency sound waves that disturb pests, scientific evidence shows they have little to no long-term impact on cockroach infestations.
How Ultrasonic Pest Repellers Claim to Work
Ultrasonic pest repellers emit sound frequencies (typically above 20 kHz) that are intended to irritate or confuse pests like rodents and insects. The goal is to drive them away from the treated area without using chemicals or traps.
However, cockroaches adapt quickly and tend to ignore these frequencies, especially in complex indoor environments like kitchens or basements where sound waves can’t penetrate walls or reach deep hiding spots.
What the Research Says
Multiple independent studies, including those from university entomology departments and the U.S. Federal Trade Commission (FTC), have shown that:
- Ultrasonic devices do not eliminate or significantly reduce cockroach populations
- Roaches may briefly respond to new frequencies but return shortly after
- Sound waves don’t travel well through furniture, floors or walls, limiting coverage
In fact, some pest control experts consider these devices more of a marketing gimmick than a real solution.
Why Ultrasonic Devices Don’t Work on Cockroaches
Cockroaches are highly adaptable and often nest deep within walls, drains or under appliances—places where ultrasonic waves don’t reach effectively.
Other reasons why they don’t work well include:
- Roaches don’t rely heavily on hearing—so sound doesn’t impact them much
- They’re attracted more to food, water and shelter than disturbed by sound
- They become desensitized to constant stimuli like high-frequency noise
Simply put: cockroaches won’t abandon a warm, food-rich environment just because of background noise.
What Actually Works for Cockroach Control
If you want to get rid of cockroaches, rely on proven methods—not gadgets. Here’s what works:
| Method | Effectiveness |
|---|---|
| Gel bait (with slow-acting poison) | High – reaches nests and spreads through colony |
| Boric acid or diatomaceous earth | Moderate – dehydrates and kills over time |
| Professional pest control treatment | Very High – targets roaches at all stages of life |
| Exclusion and sealing of entry points | High – prevents new infestations |
| Regular cleaning and sanitation | Essential – removes food and water sources |
Can Ultrasonic Repellers Help at All?
In rare cases, ultrasonic repellers may slightly reduce activity if combined with other treatments—but they should never be your only line of defense.
They may also help with rodents in some settings, but even that effectiveness is debated. Overall, they’re best viewed as supplementary at best—not a standalone solution.
