Pest Repeller, Plug in Ultrasonic Pest Control 8 Pieces, Electronic Mosquito Repellent for Roaches, Mice, Bed Bugs, Flies and more by Ansbro

I purchased this item about 2 months ago. We moved into an apartment that was absolutely infested with roaches. Since we moved out of state we really couldn't pick somewhere else when we found out. Tried everything on the market. dumped a couple gallons of poison in the place and we were still seeing them come back as other apartments were treated. I heard about these devices a couple years ago and figured we had nothing to lose by trying. The company says it could take a few weeks before you see results. but we haven't seen a single cockroach in almost 2 months. Worth every penny! And I would also like to add that my husband had been working and the trash did not get taken out for almost a week. (It got kind of smelly) and right before he was going to take it out, we noticed maggots all over the floor. (That is probably one of the strangest things I have seen so far in life). It took a minute to realize that the plug-in was right next to the trash can so the maggots fled the trash can and we're running away from the plug in. Anybody that knows the habits of maggots knows how strange it is for maggots to leave their food source and risk dying. We found a few of them almost 30 feet away from the trash can. I think this definitely speaks to how will these devices work! Just don't forget to take out your trash LOL

I was very leary at first but they actually work. I see less and less insects throughout our home. We are pretty imbeded in the woods so we were always seeing some time of critter ant, waterbug, spider etc. But now we barely see anything even in the basement. We did start to see a lot of bugs at first but about a month or two later pretty much nothing. I told my insect guy about the purchase but he seem to not want to talk about it. It may take his job. Lol I have ten located throughout the house and they seem to work for me. I also walked aroud our house and sealed every opening with waterproof silicone.

they either worked or the wasps and hornets decided to move away; put them in the shed also and no bugs there either.

Learned the hard way that it only works for a while. Damn mice get used to it. And just to piss me off, the mice left behind their feces right underneath the ultrasonic plug in. :(

I can say with no doubt that this device is not good to repel anything at all

so i bough this in may.. and so i thought they were working turns out its where the freaking raoches started coming out from behind the dam thing! and i paid $50 i let my self be fooled by the wonderful reviews

I've monitored these devices for over a week. So far it's working fine outside on repelling mosquitoes, flies, and small bees but not the queen bee. Every year my backyard would be swamped with mosquitoes, flies hovering my patio door, and bees making hive near the door. But not this year, after plugging in these repellers, I haven't seen any mosquitoes near my house even on hot humid days. But I have to say, I do use more than one outside because we have a creek running behind our house and that's where the breeding ground for the mosquitoes. So we use a few to keep them at bay and it's working well so far. On the inside, it is still working to keep pests away. It doesn't seem to work on moths, maybe it's too soon to judge. I need to purchase another eight pack for other rooms in the house since I used most of them outside.

They don't work at all, gave them time to work (have had them for over 4 months) and still have mice.
