Little bugs and critters can be extremely annoying, they also often are carriers for disease. Dealing with pests can often be a messy and inhumane process. This is where ultrasonic pest repellers come in.

By using a ultrasonic sound wave that humans or even dogs can’t hear, critters are “pushed” out by the sound waves that they can not tolerate. You do not have to worry about putting out sticky, or poisonous traps any longer. You also don’t have to deal with the remains of killed pests.

The sound waves will simply create a barrier around you and keep you pest free.

LINK Innovation Ultrasonic Pest Repeller Review

Designed by LINK Innovation this four inch tall pest repeller plugs into any outlet to begin controlling pests near you. When active the unit will emit low frequency sound waves which are unbearable to pests. The sound waves are undetectable by humans, even pets will not notice the noise.

This highly rated model will work on all sorts of insects, mice, rats, spiders, mosquitoes and more. Other pest control methods often kill the offender which leaves you to handle the remains. The sound waves simply “push” the intruders away. The coverage area of this model is 800-1200 feet.

The manufacturer does specify however that the repeller will not work through walls.

A lifetime guarantee is included, and LINK Innovations state, that if your infestation isn’t handled within three weeks (the usual time it takes to see results) you will get a full refund.

Best Ultrasonic Pest Repeller Buying Guide

If you are plan on buying a pest repeller, you want to make sure you are buying the best model for your needs. Below I list the things that you should consider before purchasing.

Money Back Guarantee
Because you can’t hear the sound being emitted from these units, it is important to feel like you are not being ripped off. Therefore it is important to look and see if a money back guarantee is offered. Most good models will offer a no questions asked money back guarantee if your infestation is not fixed.

LED Indicator Light
Again it can be tough to believe that the unit is working, if no sound or smell is emitted. So at the very least a LED light should come on when plugged in so you know that the unit is working.

Coverage Area
Most models have generally around the same coverage, but make sure you know the dimensions of the space you plan to clear, and if your desired model can handle that.

Amount of Units
As you have seen with the above reviewed models, some repellers come in kits with multiple units which can be great for large spaces. Sometimes you may only need one. Make sure you are buying the right amount of units for your needs.
