GameXcelRodent Repellent Indoor Ultrasonic Mouse Repellent,Triple Pest Control Rat Repellent for House with Latest High Impact Wave Technology and Adjustable Power,Pest Repeller for Home, Warehouse

Bought this as a replacement for a similar device that is no longer available. This version is definitely louder than that device within the high audio range (17 kHz to 20 kHz) subjectively (also according to the spectrum analyzer app on my cellphone), which some people will find unacceptable. However, if you can either tolerate the high-frequency noise or not hear it, this is the most effective ultrasound generator for repelling rodents that I know of (and I've tried about six other types).

I tried to use this repeller to keep rats out of my greenhouse, as I had been losing a lot of vegetable crops this year. It has multiple settings (different frequency sweeps), but I couldn't find one that worked against wood rats (they're particularly hungry this year because of the drought, and are coming into gardens from the riparian areas around our neighborhood much more frequently).Furthermore, it got a little wet one day and then started emitting a very loud and audible warble instead of its typical ultrasonic warble, and I was unable to turn it off without unplugging it.Maybe it'd work on mice or some less enterprising rodent, but I wouldn't use it for rats.

Idk but I haven’t seen any mice droppings and since the weather has changed the past couple of weeks this is when I normally notice droppings around my trash can so all I can say is it must be working

I am using the trap and some poison, but they do not work. So, I hope this one work for me. I do not have much problem with them, but I see some bite when I clean up the garage. I followed the instructions and stuck with it for a couple of weeks. The product comes with tons of simple and clear information and phone numbers to call for assistance. I did not need their help because after following the instructions for a couple of weeks, it worked for me. I can say that because I do not see any left behind or sign of them no more. I am really happy with this product and now I don't have to worry about rodents chewing electric wires in the house.

This is a very nice and useful ultrasonic mouse repellent. The reason I choose to try this is because no need to harm mice but use in a safe way to get rid of the mice issue. I think this is working fine so far but am going to try for some more time and update this review based on my further experience after prolonged use. Per their instructions, Level 1 for rest or evening use; level 2 for typical residency when people are around; level 3 for big warehouses or people are not around. The best part of this Mice repellent plug-ins takes up very little space and easily fits into small spaces.
