You are going to love the ET Pest Control and let me tell you why. With the ET Pest Control you can switch up the High Impact Ultrasonic sounds. This gives you the ability to put all the power towards bats/insects or rodent type pests. Pest direct targeting includes: High Range which repels BATS with great demand as well as insects. We have had positive results with these types of insects: lady bugs, mosquitoes, moths, ants, spiders, scorpions, silverfish, termites, ticks, water bugs, beetles, bees, bed bugs, cockroaches, centipedes, earwigs, flies, and fleas. The other setting is Low Range and this targets rodents which includes: mice, rats, squirrels, and other small rodent type pests. The ET Pest Control also comes equipped with sound confusion. This ability gives you two sound repelling functions which demands BATS and other pests to leave with better results.

One of the biggest issues with repelling pests electronically is that you need to give it time. It usually takes up to 4-6 weeks. In some cases the results can be instant, while other cases it takes more time. Another important issue is that you want to be in the proper ultrasonic sound ranges. And with the ET Pest Control, you will definitely be able to target your specific pest."
