What’s inside? ①2X JelleoUltrasonic Pest Control ②2X Bonus Camphor Stick ③1X Instruction How the Ultrasonic Principle works? Both male and female mosquitoes are scared of 26~28KHZ ultrasonic waves from bats. Rats will send out 30~50KHZ ultrasonic waves when they are under threat, and adult rats can even send out such ultrasound waves for help. According to this principle, electronic equipment that produce powerful high power ultrasonic pulses can interfere or stimulate the auditory system of mosquitoes and rats effectively. Pests will feel insufferable and panic, showing symptoms of twitching and escaping. In this way, JELLEO achieve its goal of repelling pests successfully. The auditory range of human ear is 16~20 KHz or so, while the output power of the ultrasonic rat repeller is over 20 KHz generally. Besides, the power of ultrasonic pest control is relatively small, generally about 4W, which is unable to affect human body. At very beginning, there will be a large number of pests because of their inability to adapt to the ultrasonic living environment. After 2 to 4 weeks, it will create effects. Tips： To ensure the ultrasonic repellers work right, we need to pay attention to the two characteristics of ultrasound: Fast Decay & Poor Penetration. Ultrasound can’t pass through the barrier but mice, cockroaches are mostly living in a hidden corner. To maximize the function of ultrasonic repellers, we need: 1. As far as possible, reduce the obstacles in the propagation direction of ultrasonic wave. 2. Ensure the propagation direction of ultrasonic wave has crossed the area of frequent pest activity. 3. If the room is large or of complex structure, please do not hesitate to layout more than a few ultrasonic repellers. Warning: If you have insects or rodents as your pets, it is not suggested to use the ultrasonic pest repeller.

Didn't work for me.
No difference in over a month. Waste of money. Hard to find locations to plug them in as instructions say practically anything in front of them will prevent them from working. Height also makes a difference according to instructions. Unless you have low sockets with a lot of open area, placing them will be a challenge. I rearranged furniture to accommodate them. Also plugged them in sockets on kitchen counter. It's been over a month and the only difference I see is a lot of annoying night lights wasting electricity. Still see occasional ants, spiders and bugs in the house just like before I plugged these in. Instructions say you have to give them time to work and you will see increased activity initially while bugs are trying to leave. I think the wait time is more so you will have them long enough that you will have tossed the box and won't be able to return them. Not only did I not see increased activity, I have yet to see any difference at all.

wont recommend anyone to purchase it either
Bought it at the end of June, Only works for mice. If you want use it for the purpose of getting rid of the Cockroach, dont even bother. It has no effect on cockroaches or any insects at all. beyond that, it only worked for 2 month which make me even more mad. Wont come back to purchase it again, wont recommend anyone to purchase it either.

Not worth it. It didn't work for me. I purchased this to deter spiders in my garage. Seems to have absolutely no effect on them.
