After a month of using it during the summer, working all night, it had killed 4 mosquitoes and 3 flies, in complete darkness in a room where I used to have 2-3 mosquitoes before going to sleep and another 5 buzzing in my ear.

It doesn't work very well. But it will never need cleaning, as it will never fill up with dead mosquitoes.

For its size, it collects quite a few mosquitoes. It definitely doesn't do the job like the liquid, but you will rarely see mosquitoes in the area.

I bought it for mosquitoes, so far none have been affected, but it has killed some flies that are flying around some fruit... I believe if a mosquito enters the house, the same thing will happen.

Because a picture is worth a thousand words, I am uploading three, because this particular insect trap really does the job with visible results! It's worth its money!
