I want to start by saying that I don't usually leave reviews. However, this product literally saved us from having a much worse situation on our hands. Originally, I bought this product to get rid of our cellar spiders that keep popping up in the corners of our rooms. They drive me nuts and I couldn't seem to stay on top of them enough to get rid of them fully. So I did some research, found this product, and decided to give it a try. I stuck it in every single room in the house that I noticed had a visible spider issue. About three weeks into having it, I decided it wasn't helping with our spider issue. I took them all out of the walls, boxed them up and planned on returning them. Around this time, I kept telling my husband that I was hearing something in our bedroom. We have what I call a dog house, where there's a small outlook room within our bedroom that has a huge window. The doorway dips down a little bit lower than a standard doorway, so depend on how tall you are the ceiling leading into this room is only a couple inches away from your head. We were able to sneak our dresser into this area, so I frequent it throughout the day. Anyway, every time I would step under that threshold into the room, something in the wall would hiss at me. One day, I got so annoyed with the hissing that I ended up tapping on the wall. The hissing grew more aggressive, and louder, and I thought for sure it was a huge animal like a possum or something. This part of the wall / ceiling is sheetrock, etc. My husband swore that he couldn't hear anything. Either way fast forward to Friday, I planned on returning the devices tomorrow and had them packaged in our kitchen ready to go. I work from home, and I'll usually change out of my pajamas into some real clothes around halfway through my morning. Like normal I head into our bedroom, which happens to be right next to my office, and go about getting ready to change like I normally do right in the mini room connected to our bedroom. As I'm taking the clothes out of the dresser, a wasp flies by my face and lands on the wall next to me. I know you all are certain where the story is going at this point, but I want to preface the fact that we usually leave the windows open in the house, so a stray wasp isn't that uncommon. What is uncommon, is another wasp flying past your face and landing next to the other one on the wall next to the window. I was so focused on the two wasps that had land on the wall, that I didn't initially realize that the buzzing (hissing) noise was coming directly above my head, where the doorway came down just slightly before entering the mini room. I knew something was wrong when the two wasps on the wall multiplied to four. I also want it to be known that I had set my phone down on the bed prior to going into the dresser. Anyway, I finally became aware of the location that the humming noise was coming from and looked up from where I was standing. Above me, like a small leak in the wall, wasps began to flood out. The more that came out the larger the hole grew. The larger the hole grew the more wasps were able to come out. Me, being the quick thinker that I was, grab the clothes I was planning on putting on and fled the room, shutting the door behind me. I stepped back into my office looking for my phone so I could call my husband and let him know the chaos that has unleashed in our bedroom. Unfortunately, I could not find my phone. Horror dawned on me when I realized that my phone was in the warzone formerly referred to as our bedroom. Now our bedroom door had about a half an inch of space underneath it, big enough for socks could slip through. If a saw could slip through a horde of wasps could as well. I put on my brave girl pants and stepped back into the bedroom. My plan: grab the phone and get out. I made it in and shut the door behind me to make sure the wasps didn't spread to the rest of the house. Most of the wasps went straight to the giant window. Some curious ones flew past me, but the overall side of our bedroom had me in shock. This is the type of thing they don't prepare you for when you become an adult. They scare you with the bills and the responsibilities, but they don't tell you that one day you're going to have something in your home that should not be there. And that day you're going to have to decide whether or not you're going to burn your house down or you're going to resolve it maturely. I'm not afraid of wasps, but boy my husband sure is, I just couldn't wait to give him the run down of this. I grabbed my phone, and since I wasn't immediately getting stung to death, I decided to call my husband right there in the bedroom. He didn't believe me at first, when I told him there are wasps in our bedroom, he said well capture them and take them outside or kill them. It took a few minutes of explaining before the "thousands of wasps in our bedroom" turned into an emergency situation. I ended up leaving the bedroom, navigating into my office, grabbing a wide mouth plastic cup, taping the ends of it with tape, and navigating back into the bedroom closing the door behind me. Ideally I was going to take the bowl put it over the hole in the ceiling and keep it from letting more wasps into our bedroom. To me it was a flawless idea and there would be an even more flawless execution. I pressed the bowl/widemouth cup against the ceiling with the intention of it covering the hole, and I planned on using the tape to hold it in place. However when I press the wide mouth cup against the ceiling, rather than meeting something hard, something that would provide resistance like you expect the wall or ceiling to do... The cup sinks right into the ceiling. At this point the wasps are not happy, they haven't quite found my juicy body yet as a target, but when I tell you the cup drops and they come out of the ceiling in a comical cloud, I mean it. The sound of about a hundred wasps coming at you in a black cloud could easily be the most terrifying thing for most. Fearing for my life, I high-tailed it out of that room and shut the door. Thankfully the wasps never found the sock-sized crack between the door and floor. I decide to go back to work, there's nothing more that can be done and I plan on leaving that door closed until my husband comes home with whatever idea he's come up with. I take a later lunch than I'm used to, and it's been about 3 hours since the incident with the wasps. The buzzing noise outside the door has since quieted, so I imagine that maybe they crawled back into their hole and left on the first flight out. Rather than opening the door right away, I decided to go into the kitchen to eat my last meal in case things were to go south. On the kitchen table, I catch sight of my return. It gives me an idea. I reopen my return, pulling out three or four of the blue lights. I stuffed them in my sweatshirt pocket and head back to the bedroom. I open the door grab my phone, turn on the flashlight and begin sticking these blue lights in every single outlet in our bedroom. I stuck so many in that small room, that it lit up blue. Evidently I also took a picture of the hole in the ceiling, which what looked like sheetrock is actually a foot long wasp nest that they had built in our in our bedroom. At this point wasps were still flying around and had multiplied enough where they completely covered our huge window. I ended up letting the blue lights sit and I went back to work. My husband got home that evening and I stopped working right around that time. We decided to go in at that point and check out the bedroom situation. I had not been back in there since I placed the blue lights and all the outlets, but when we opened up the bedroom door it was silent. The buzzing noise that was so loud earlier, was gone. We stepped in and turned on our bedroom light, and took in the scene before us. Dead and (some were still twitching) wasps covered our floor. As we stood in the bedroom taking in the scene before us, we watched a few wasps fly out from their nest on the ceiling and into the bedroom. We watched some fly around for a few seconds before dropping to the floor where they remained until they twitch their last twitch. We ended up sleeping in our kitchen that night, we closed the door and managed to get the window open from the outside. We left the blue lights in, let them do their thing, and the next morning you're able to fully extract the nest without any spray, just the help of the lights. It was so impressive that when we came down that next morning was a pile of larvae on the floor beneath where the nest was in the ceiling. This was to date the craziest experience I've ever had. The blue lights also help with the mice, so I found that it's just handy to have them in at least one of the walls in your house. At this point, you never know what could be nesting in the walls.

We're still seeing crickets in garage where we have 3 units placed in garage.

Having a cat, I can't have poison in the house, so I rely on makeshift solutions like peppermint (which bugs and mice hate, apparently). Lots of crickets in the house every fall, why I don't know. Do I kill them? You bet - by the hundreds. Have only seen one cricket so far - immediately after I installed the device. The cricket was acting really strangely, jerking around - so that was the result of this device messing with its nervous system. Had an enormous spider appear in the sink yesterday (ended up going down the disposal) so now I'm putting one in the basement; have one or two in every room. So far, I love them (we'll have to see how it handles any future spiders, however). I'm using them along with mint & lemongrass spray. No poison, no awful smells - so far, it's great!

I bought these in May and they worked great- I did not see one bug all summer long, it is now November and I am seeing spiders in each room. So do not know if it no longer works and needs to be replaced, or because it winter time. (i dwell in the midwest. Does anybody know how long they are suppose to last. Thank you

I purchased these and not sure if they truly make a differenceI do know that they do make a very nice night light

We were having a terrible time with stink bugs getting into the house. We put these in different areas and in windows. No bugs. Guess they work

They may or may not be repelling bugs, but I really hate the lights on them.
