We have a problem with mosquitoes (Culex pipiens) in our apartment in Boston. We have no clue how they get in our home and so we sleep under a mosquito net to avoid nighttime bites but are stil attacked when we are not under the net. I bought this unit out of desperation, in hopes that it would catch the little pests. It looked very promising, with it's sticky paper, attractant bait and warm humidity generation, BUT I've had it plugged in and assembled as per the instructions for over 3 days and the unit has caught NO mosquitoes. Meanwhile, my girlfriend and I have killed three ourselves, the old fashioned way, by slapping them as they try to suck our blood. Unfortunately, this product is worthless. So we'll be sleeping under our mosquito net for some time to come....
