I'm not sure if these traps work. I haven't seen any dead gnats, fruit flies etc. lying around or near the traps. Using a magnifying glass, it doesn't appear like there is anything inside. I will give it three stars just in case I'm missing something. But I honestly don't know that they are doing anything. I purchased the first round a little over a month ago. Then I replaced those in about 25 days (not waiting a full month), still . . . . . .?

We had gnats/fruit flies really bad in an area in our garage where we keep crushed cans to recycle. This trap really did the job! The trap was completely covered in no time with the little pests and I've replaced it several times. I also used it in our kitchen where we've had much smaller problem. My only complaint was I didn't get the Pest Guide Book in my order.

This really works to keep those fruit flies gone !

Works like a charm combined with sticky paper. Got rid of them all in a week.

We compost all our food scraps. Couldn't live without this next to the pail on the kitchen counter.

Works great!

These traps are useless. Look for another product, but don't waste your money on these. I would have given no stars if that had been an option.

I used this product last summer and it worked wonders. However, I have a number of the traps out now and they have not been as effective.Disappointed!
