Last night I bought a Stinger 40 Watt Electronic Bug Killer from Lowe's to help control the insect population around my new house. Unfortunately, it looks like ultraviolet lights don't attract mosquitos very well, and those are the bugs I hate the most. The reviews of the product on the Home Depot site indicate that it works well, but How Stuff Works says that although it kills lots of bugs, most of them won't be mosquitos. Still, the device comes with an Octenol cartridge that's supposed to attract biting insects, so we'll see how it goes.
If it doesn't work, I'll just return it in a couple of weeks. I may end up having to spend real money on a mosquito magnet.
