This thing works! We have been unable to enjoy our deck during summer months in Colorado, until now! Thanks to this small, affordable and efficient device, the bats fly right by our deck. No more bat poop! Hooray!! A million thanks!

I seriously did not think I would need 24 to begin with, I was wrong. I am using them outside for plants and growing veggies and such. Did not seem to deter aphids though, but I have homemade spray for that and recently saw ladybug larvae outside so that will be taken care of shortly. I had hopes of catching whatever else is going after my mexican marigolds, avocado and other plants. I used 3 bottles of super insecticidal soap and not the results I was hoping for. Surprised I caught soooo many critters (not bees- which I have lots of) . I did put on the bottom of the plants and some I rigged for top inserted on a stick...and wow. Mosquitos (damm them) got stuck, few less to bite me even better. Flies (small ones) gnats and I think whiteflies too and some I'm not sure what they are. Already used about 18- and have to replace many covered by bugs, so I ordered a larger pack. So easy to use and versatile. It's nice to be outside again.

They are using name colors to describe different styles and number of products. I thought I was getting clear. I'd change my review to 5 stars if they changed the names of the different packages because these things really do work! It's just kind of deceptive to use "clear" and "blue" to describe styles when all that's available is bright yellow.

2/8 of the devices literally make a screaming sound on repeat, and when I had the rest of them plugged in it was no time at all before I could hear them, too. These are supposed to be on frequencies that only the critters that they’re supposed to repel can hear but they disturb the humans and cats in my home as well. I’m returning them and reading reviews more carefully next time - most of the good reviews for this product are about a fly trap, not the plug in pest repeller that I purchased from this same page. Those kind of practices tell you a lot about a seller, switching products on a page with good reviews to keep selling their junk. Buyer beware!

Great product

I work in the office at a landfill and we get bighting gnats in here so bad that it becomes hard to concentrate on work from all the hand waiving and swatting.One of these taped to each window, and to each monitor and the problem all but disappeared.

I put this in all of my potted plants indoors. They really work well and month after month it serves the purpose. Those pesky fungus gnats are caught in no time. The spike is a bit soft but with proper technique it goes through the soil and stays there. Packaging is also really nice. I feel like I got my money’s worth. I’ll buy more.

I stick these in my plants and they work so good. Always get so much fruit flies at the end of the day
