Via 37signals’ Signal vs. Noise blog, I came across what seems like a really simple idea that looks like it actually works: the Skeeter Bag.
What is it? Basically, a box fan with a mosquito attached to the front of it. Flip it around so that your CO2 (or your dog’s, livestock’s, etc.) blows out toward the bugs. Then, when they come to get you, they get sucked into the trap, unable to fly against the breeze. It’s a similar idea to the Mosquito Magnet, but apparently works better, and for about 1/30th of the price.
I like the simplicity of this, and hope it’s as effective as the website claims. Let me know if you give this a shot!
