The Mosquito Magnet sells three versions I think. The two that were mentioned and a $299 model. Tyhe wind conditions are correct as you have to stay in the plume of the C02 much like a Citronella candle but who wants to stay in a plume of smoke. The Coleman sold a bunch of their units then had a recall which brought them back. Insecticides can be very nasty. Depending on what chemical they were spraying it is quite likely it was making animals sick. It takes alot less of an exposure for a dog, let's say, to get sick than for a person to get sick. People in that area were being exposed to it and possibly getting sick but ddidn't put two and two together. Maybe when children are born with six fingers they'll link it back to the insecticide they used. Many pesticides (universal name for insecticides, rodenticides, mitacides, herbacides ect. ect.) are banned in this country because they cause mutations in the unborn. Liberals, well in a round-a-bout way they were doing more good than harm in this case if the stuff was bads for us. Drew
