The claim that this unit produces carbon dioxide (and hence ATTRACTS mosquitoes) is highly dubious. True, the units traps stray mosquitoes that venture near it. But so do other similar products that cost one-fifth of the price. Forget one-fourth acre, the unit is NOT effective over an area of 30 square meters in ideal conditions (operating at least two hours in complete ambient darkness without human presence). It certainly does not 'attract' mosquitoes, hence the claim that it produces carbon dioxide is suspect. It only traps stray mosquitoes that are attracted to it by its light -- at four or five times the cost of similar products that are just as effective.

This thing works! After the first night in my bedroom I counted 29 no-see-ums stuck to the sticky pad at the bottom. The little bugs are almost too small to see, but they leave a nasty bite. We live in the Sierra foothills and how they get into our house in such numbers I'll never know. Normally I wake up with bites anywhere I am not covered. I have owned similar devices, but this is the first that has a near-silent quality fan. I do have to say that the tuned black light is very bright. I had to block the light from spilling over to my bed. It makes a nice nightlight. That said, I rate it at 5 Stars!

A friend recommended these. We bought one of the 1/2 acres versions, and liked it so much, we bought a second 1/2 acre and this 1/4 acre.

They do capture a lot of moths and hopefully mosquitoes, and it is easy to empty the capture tray on the 1/2 acre. It is annoying to empty THIS 1/4 ACRE version.

Just note that the 1/2 acre version has a much more robust cord that the 1/4 acre. I wouldn't buy the 1/4 acre again for anything, it's power supply is cheaply made and you have to use a power adapter for it, so you can't really use it out of door, or at least only on your covered patio.

I bought a fly killer lamp a few weeks ago and the truth is that I am quite satisfied with the results. From day one I noticed a significant reduction of insects in the house, especially in the kitchen and on the balcony where they tend to accumulate the most. It is quiet, does not emit annoying odors and best of all it does not use chemicals, so it is safe to use around children and pets. Plus, it's easy to clean and its power consumption is minimal. Honestly, it has been an excellent purchase, especially for the warmer months where insects tend to be more annoying. I highly recommend it.

It works
