Pros: Active Model looks great and seems built to last
We purchased both the active (vacuum) and passive (adhesive) Mosquito Deleto systems last weekend for our cabin and I can say with no hesitation that the passive system is a complete waste of money but the active system really seems to suck them in. We ran them at the same time on opposing sides of our property and over a period of two days the passive system caught about 10 mosquitos and the active system probably caught about 300 of the little nasties. The jury is still out as to long term benefits of the system since we have only had it for a week but I can say that between the two systems the active one is definately the way to go. We got ours at a home store and the passive system was around $159 and the active system was $399 so it is quite a bit more expensive but I would say it is worth it. I am pretty surprised Coleman would keep selling the adhesive model since I was using it in a very heavily infested area and it still didn't catch any bugs. If you want to get the same effect without spending the $160 put some flypaper by a light and you will probably have better luck. If you are willing to pony up the $350-400 dollars I think you will be satisfied with the active system. It seems very comparable to the Mosquito Magnet. If you read the reviews for the Mosquito Magnets on Amazon they are not exactly glowing from a reliability standpoint so I hesitated to spend the $800-1000 their deluxe models cost. So far I am happy with this unit and I will post again if things take a turn for the worse.
