Ultrasonic Pest Repeller[2-Pack], Roseny Electronic Pest Control Repellent Plug in for Mosquitos, Insects, Bugs, Rodents, Mice, Spiders, Ants and More

My back yard is essentially a very large “creek” (more like a river)The water makes for more knats, moths and mosquitos. We typically can’t open our back deck door after dark because the swarms of knats fly in so quickly. (They are attracted to our lights inside)We bought one of those lights that zap the bugs but that wasn’t enough so I bought these too. They work really well and I’ve noticed a huge decrease in knats by the door. I am going to buy a couple more.

I'm not sure if it's the weather change or if this is actually working but there are some small changes. Nothing too big but I didn't have many noticeable critters around to really impact it. I feel like I can hear a buzz but it could just be me or the fact that it's constantly in use with the electricity, the same thing happens with larger electronic devices. Hopefully in a couple weeks I'll see more of a difference with no creatures around my balcony.

Every year in the spring I have these nasty wolf spiders parading around my carpet at night. That show up every year because of the change in weather. Well THIS year I tried putting these insect repellent plug ins in my hallway (the coolest hangout for those dang buggers) and so far I haven’t seen a single gathering! Very pleased. I’ll have to get more and test it out in the utility room in my basement.

I’m so glad to have found this product! With small children in the house, I worry about sprays and traps. I’ve been using this for a week and have already noticed fewer creepy critters around the house.

We have high hopes for these and wish that they can help us with the issue or racoon's in our patio/yard along with a ton of other pests.We are optimistically waiting for results after 2 weeks of use.

Seemed to keep the bugs away in Croatia. Other guests said they had bugs in their room but I did not. I don't know if it was this that kept them away but we were bug free for over a week.

Had it for a few days and for right now it does not seem like it is working. I know increase electric bill and takes a lot of usage. Will update in about a week, but as of right now. It looks like a waste of money. I hope not.

still seeing a roach in my kitchen but very rainy here.
