4-Pack Ultrasonic Pest Repeller Plug-in "Brand New" Moisture-wicking material helps draw sweatOnce plugged in the ultrasonic pests repeller delivers a high pitched frequency in the room. This frequency is unnoticeable but humans, but highly repelling to insects and pests. Since they are repelled and rejected by this ultrasonic frequency, they will never enter that room. More so because of our double speaker design that doubles the effect of the normal repellers. Now its time to say goodbye to your worries related to insects and pests.
