<p>The Best Ultrasonic Pest Repellers That Repel Pests Quietly and Effectively - If you are considering non-chemical methods of getting rid of pests, we recommend that ultrasonic pest repellers are devices that emit continuous noise at a frequency that is too high for humans to hear. These sound waves are designed to distract, harass and deter common household pests such as cockroaches, spiders, mosquitoes, ants and rodents. The intelligent multi-frequency ultrasonic conversion system gives pests nowhere to hide.</p> <p>, protect your family in a healthy and happy way - the repellent is safer than traditional mosquito repellent.

All you have to do is plug the pest-repelling ultrasonic into an electrical outlet and when the blue night light turns on, it starts repeling pests. The rejector should be placed where its noise will not be affected by walls and furniture.
