The battle against roaches is a constant struggle for homeowners. These resilient pests can infiltrate homes, causing discomfort and potential health hazards. One of the methods homeowners use to combat roaches is ultrasonic pest repellers. But do they work? And if so, which is the best ultrasonic pest repeller for roaches? Let’s delve into this topic to provide a comprehensive understanding.


The best ultrasonic pest repellers for roaches, based on customer reviews and features, include the MaxMoxie Ultrasonic Pest Repeller, the WahooArt Ultrasonic Pest Repeller, the Zero Pest Indoor Ultrasonic Repellent for Roach, and the TBI Pro Ultrasonic Pest Repeller.

What is an Ultrasonic Pest Repeller?

An ultrasonic pest repeller is an electronic device designed to emit high-frequency sound waves. These sound waves, typically beyond the range of human hearing, are intended to cause discomfort or confusion in pests, encouraging them to leave the area.

Do Ultrasonic Pest Repellers Work on Roaches?

The effectiveness of ultrasonic pest repellers on roaches is a contentious topic. A study by Kansas State University found that ultrasonic devices have minimal repellent effect on roaches. Further research by the University of Arizona mirrored these findings, concluding that ultrasonic pest repellers have no significant impact on cockroach populations in infested apartments.

However, some users have reported success with ultrasonic pest repellers against roaches, suggesting that the effectiveness of these devices may vary. It’s important to understand that ultrasonic pest repellers may not be an effective standalone solution. They should be used in combination with other pest control methods, such as bait stations, traps, or professional pest control services.

Cost of Ultrasonic Pest Repellers

The price of ultrasonic pest repellers can range from $10 to nearly $100. Factors that affect the price include the device’s range, the number of devices in a pack, and the brand’s quality. However, a higher price does not necessarily indicate better effectiveness.

Using Ultrasonic Pest Repellers Correctly

To maximize the effectiveness of an ultrasonic pest repeller, position the device in an area where roaches are frequently spotted. Use multiple devices to cover a larger area. Remember, ultrasonic pest repellers should be used in conjunction with other pest management strategies.

Customer Reviews and Feedback

Customer reviews and feedback regarding the effectiveness of ultrasonic pest repellers on roaches are mixed. Some users report positive results, while others claim the devices are ineffective. It’s essential to consider other pest control methods in combination with ultrasonic repellers to achieve better results in controlling roach infestations.


While ultrasonic pest repellers can be a part of your pest control strategy, they should not be the only method you rely on to combat roaches. Their effectiveness is uncertain, and they work best when combined with other pest control methods. Always consider the specific needs of your home and consult a professional if roach infestations persist.
