Ultrasonic Pest Repeller, Indoor Pest Control for Mosquito, Mouse, Cockroach, Bug, Roach,Upgraded Electronic Plug-in Insect Repellent for House, Garages, Warehouses, Offices, Hotel,6 Pack

I had a family of mice in the ceiling of my RV. I could hear them scratching and running around. I tried traps and got a few, but I had to do something different. I had had a similar set of these, and had them all over and never had a problem. I had had them plugged in for two years, and I guess they stopped working. I purchased these, I plugged them in all over and by the next day not a sound.

This didnot help me at all.I have been using it for more than 7 weeks and there are no effect on the roaches.Not as good as it says.

We were invaded by fruits flies, but 2 months after I bought this set set of 6 plugs-in, I have not seen any. Consequently, I have bought more and plugged one or two depending on the room dimensions. Ultrasonic pest repellers can last three to 5 years. Their sound waves are too high and our ears cannot vibrate fastenough so it does not bother us or our cats' and dogs' but rodents, fleas and other insects. One should not use it if ones has pets from the rodents family.Studies have demonstrated that after a while, nuisance gets used to it...to sumarize, it seems their efficacity is not always good. Thus, they do not pass through pieces of furniture or walls. I had to buy 2 sets. The blue light just indicates they are plugged. It is better if you have plugs up above the gound like 1 m. Some people reported headaches. I had none personally, but I guess I would check the last reliable studies available.

2 units did not work. Very low quality assurance

I'm going to keep os simple. It does not work for roaches. I've tried everything

This product is useless. Absolutely does NOT WORK.

This is not what I expected it’s been a month and I still see roaches not a lot maybe 2 or three but I’m not supposed to see any. So I’m gone try another kind.
