HelpANYONE using one of those Mosquito Trap Machines?

Around my house, we have a serious problem with mosquitoes and biting flies. I have thought about getting one of those mosquito trap machines that work with carbon dioxide, scent and a blower that sucks the nasty critters down to their death.

But from what I have read, the machines do not yet work well enough to be worth buying.

I'm kinda concerned about the various illnesses mosquitoes can be carrying these days, and I don't like spraying mosquito repellant on myself every time I go outside.

So would like to know what anyone thinks about the mosquito trap machines---if anyone has used one and if they thought it was of much effect, and if it was worth the money.

Thanks for any and all opinions!
