Bell + Howell UltraSonic Pest Repellers

I have 5 repellers all over the house including the garage. It's getting cold in the Pocono mts. when the field mice start making their trek inside, so far no noise but I don't expect the repellers to keep all the mice out. I think some will ignore the buzz, nothing is 100%. Like I said I had 2, 1 in the basement and one in the living room and every once in a while I would see them. It's only been 2 weeks since I put the other 3 in operation but it has been quiet.

I got this to keep away mice. My backyard is a forest, so they come looking for a home when it gets cold. I used to find mouse droppings in my kitchen drawers and cabinets. I haven't seen anything in over a week! I also usually see a decent amount of crawly things around my house due to my surroundings, and those seem to have dwindled too. I can't use traps because I have pets, so these things are amazing!

Very happy with product and especially delivery . I like that it has on and off night light switch.

Surprisingly these units work great. I bought these because my son said that he bought some and it worked great too. My advice would be to buy this model don't go with the cheaper one.

I am amazed how quickly it worked! I had a critter in my attic foronths. Started hearing it in my walls. Plugged in all three units and by day two it was gone! Again AMAZING!

these work extremely well on tiny insects like dust mites and paper mites, but the larger the creature its effectiveness will depend on if the creature already has a " home" there. And its a great product but be aware and realistic of its limitations: room size 10x12 or smaller per unit; carpet, soft furniture, etc absorbs waves and reduces effectiveness; solid walls, and solid objects increase effectivess by echo.

not sure how to really rate this item. i have only had them plugged in a few days. seems to be working but not a hundred percent sure. i sure hope they work though i hate mice.

About 10 years ago I purchased ultrasonic pest repellers after seeing a mouse. Much to my surprise I didn't have to worry about mice or roaches. I do spray my house with insecticides and I don't know if that helped me get rid of the mouse. I just purchased the Bell & Howard 3-pack and they don't seem to do anything except blink. I am about 3 feet from the plug -in and I have observed (for about a month), the mouse continue to run through my room being less than 5 feet away from the repellers. Please don't waste your money.

Is electonic roach repellant after plugged in for 1 month i checked it and roaches had swarmed it

Don't work
