Bell & Howell 3-Pack Ultrasonic Pest Repellers with Extra Outlet

I had a small ants problem and had been using ant bait but wanted continuous coverage. I had to wait around 4-5 days for complete elimination of them as well as the roaches I didn't realize I had. No mice detected. The flashing light does not bother me. The outlet option is necessary.

I have always had mice in my home, which is built on top of the ground. I thought I would try this product and I haven't found a dead mouse since last year. I don't know if it's because of this repeller or not but it's the only change I've made and I am really glad I did. I highly recommend this for mice. I'm not sure if it works as well for insects, though.They're inexpensive enough to try them.

Overall Ultrasonic Pest Repeller ,made by Howell sold by Walmart was very excellent,outstanding method to use on controlling roaches coming to your place. If I knew it long time ago I'm going to order this item long time ago, I used all the spray,fogger to get rid of the roaches but it did not work at all,but this Ultrasonic Pest Repellers for Roaches work so fast.

when i first opened these one did`t seem to be working, but i left it plugged in, and in a little while i looked at it and it had started working, I was so glad then, and i have not seen any more pest, so they do the job they say they do, and i`m so glad, I don`t have to set mice traps, or get rid of the dead ones anymore.

Too early to tell if they are working,I would want to go 6 months to a year with no mice in the basement and no insects in the kitchen. Price is good.

I used the first pack of (3) in my house, quite successfully! So this package is for the garage! I put (2) in the garage a week ago, and haven't see any spiders or mice. As the weather gets colder, I hope these repellers will keep them out!

I have not seen any more of the pests since I first plugged in the Bell and Howell units. I am so pleased that I ordered another set. We wasted money on traps, baits and Orkin services before buying the Ultrasonic Pest Repellent units. Having the option of an extra outlet makes them very convenient. I would highly recommend them to anyone having problems with indoor pests.

its made very well,but didn't work in my home. The mice run past me ! !

I was hopeful about these as previous reviews were mostly positive. I have an issue with house spiders and sugar ants in the spring. I used 6 of these in my small apartment. My issues got WORSE. As soon as I plugged them in the sugar ants, which I had not seen in the house for 3 weeks reappeared. I had to spray insecticide to kill them but they showed up in a new part of the place; I sprayed those as well and now have only seen a few not a whole line as before. I did have fewer of one type of spider but 2 other types replaced them. I have left them installed for approximately 8 weeks now and my original type of spider has returned along with their new friends. I spray them also and it lasts a few days then they come back. Also these make a clicking noise that I can hear--its like someone flicking their fingernails. One could probably get used to that, like a grandfather clock; however these also have a red light on them. Each time these click or pulse a very bright white and red light flashes producing a strobe effect. Thus interfering with my sleep. They give me a headache sometimes. I used some black tape around the lights which may have affected their performance but I was able to get back to resting properly again; until the tape lifted. If you are light sensitive, epileptic or suffer migraines do not get these with the lights on them. I would not get any as they did not work as described. Back to RAID, vinegar and baking soda.

No indication that it works...just flashes a red light to say it's working. Ants still around
