    Excellent Project

    Couldn't believe the amount of flying insects it caught in the first 12 hours in our kitchen . I was so impressed that I bought a second one for our basement!

    Worth the money.

    Worked like a charm w annoying gnats near my plants. I ve been overwatering turns out. These little blue sheets are amazing! One round of two inserts did the job. So happy.

    It works

    I don't know what other people's expectations were, but I expected to see dead bugs on the glue traps. I've now used these in 2 homes in 2 different areas of the country (cold %26 dry vs hot %26 humid), and they work the same in both places: they trap bugs on the glue, where they die. I've gone through all of the refills they've come with multiple times, with them all being covered in things like fruit flies, moths, houseflies, mosquitoes, gnats, etc. THEY WORK! When the traps get full, I change them out. No problem. If they're full, bugs avoid them. They're great in kitchens and bathrooms. I'm now testing them in other rooms. Hopefully, they work just as well in those. Refills beyond what comes in the box are no problem, either, they just come from a different store. *I'd have included photos of all the dead bugs on mine, but I literally just changed out the boards last night. Sorry…
