GreenGuardX Ultrasonic Pest Control Repeller (2-Pack)–Indoor Repellent for Mice, Mosquitos, Roaches, Spiders, Insects, & Rodents – Ecofriendly Bug Repeller–Children & Pet Safe, Non-Toxic

I was very skeptical, but these actually worked!I lived in a cheap 200sqft apartment in the country to save $$$, and all windows did not seal and one did not close properly. As a result - bugs were everywhere! I saw 10-20 a day in my place, from mosquitoes to flies to spiders to stink bugs.I bought these and put them in on a lark. The blue LEDs gave off a lot of light pollution and affected my sleep. I opened them up and put electrical tape in spots and that helped.Week one, maybe 65% of the bugs went away. Weeks two and three, they all came and then some with a vengeance! I heard this sometimes happens, so I decided to be patient. Sure enough, week 4, 95% of the bugs were gone! From there on out, I saw maybe 1-2 a week for the next 6 months. After a while a spider took up residence near it... and it didn’t bother it.YMMV

So disappointed in this product. I watched mosquitos, ants and flies completely ignore these plug ins. And before I could even tell my husband about them he asked me what that new high pitched hum was in the house (I can't hear anything, but his hearing is more keen than most). We suspect they were bothering the dogs too. I had such high hopes that these would work I told my family about them and they ordered a set while they were on sale, and they were just as ineffective. All these things seemed to do was provide ambient lighting for the bugs.

I can't believe these actually work! I have not seen any ants or spiders since I plugged them in. Or mice! It's mind baffling. The first two days we had a bit of an infestation with ants crawling out of the walls but after that, nothing. I'm still skeptical, and will update my review if they come back.

These things don't work at all!!! Five one plugged-in close to the intake vents for my air conditioning and when I went to clean my filter a spider had made a home in it. I have fruit flies I can't get rid of and I have one in my garage and still have roaches and ants.What a waste of money!! do yourself a favor and use the money that these cost towards an exterminator

I've been using this product for a couple of weeks. I've had an issue with roaches even though the management company of my apartment complex allegedly has sprayed around the exterior of my unit. (I won't subject myself or my pets to spraying insecticide in my home). There was some activity of the pests in the beginning but it looks like it's under control. I am very pleased with this product!

Not happy about the product. I'm very patient about waiting, but this product isn't effective against roaches! I bought the two pack and followed the instructions and after two- three weeks, no satisfying results! I'm also confused on why there are different looks of this product. Beware!

I placed one by my back door one by front door and one by the door that goes out to my patio and one in my sons bed room because there is a window in there that is close to back patio. We have noticed a significant reduction in all sorts of pest..from flies to mosquitoes, My land lord is going to be spraying the whole building to get rid of anything that was here before we put them up so i would like to update after that.

This is an awesome safe repellant and I bought 2 extra to put in my basement. It really works great and is safe for dogs and cats..which I have in my home. After 72 hrs I started seeing results and now after 3weeks I see no ants and no spiders. I noticed that spiders that are found in a corner are curled up and dead. My home is approx 1200 sq. Ft. And I did a double whammy 2 on each level. Would recommend this and is an affordable way for safer free insect home. Thank you Green Guard!!!
