They do attract mosquitoes, that's their job. They attract the females (which are the biters), and thus there is a cumulative impact on decreasing the mosquito population as successive crops of females are wiped out.
We use CO2 traps and live on the water on the Texas Gulf Coast. We have mosquitoes up to 12 months a year and I can attest to their efficacy.
The key is knowing how to use them. Never put them near your outdoor seating areas, they attract mosquitoes. Seems self-evident, but people who complain about traps usually have them too close to their areas. About 30 feet away, preferably upwind, seems to work best for us.
If I'm on the lee side of the house working in the yard or garden, I'll wear a DEET repellant, but for everyday mosquito control; sitting out in the morning with coffee, hanging out in the hammock during the day, or sitting on the deck for happy hour until after dusk, the CO2 trap works. We don't have to spray pesticides on us or our wetland marsh. We don't want to kill the dragonflies and butterflies, etc.
Give it a try, how cheap and easy is it? Much cheaper than the propane powered SkeeterVacs, which also work wonderfully, when used correctly. If you don't like it or it's ineffective, you're out a 2 liter bottle and a package of yeast.
You don't. Many traps do just that. The ones that are in the trap are not biting you, but there is a pretty much endless supply of mosquitoes. Unless you have a screened in area or it is inside, which would limit the "supply". I live in mosquito country, and don't waste my time with traps. Use a repellant with Deet or use an Off Mosquito lamp or Thermocell to repel them from outdoor areas.
