I went to Walmart and bought a bottle of Listerine for $1.89. It really doesn't take much, and it is a big bottle, too; so it is not as expensive to use as the can of Bug-Spray you buy that doesn't last 30 minutes. I tried this on my doors (Don't spray directly on a wood door) but spray around the frame. I sprayed around the windows and you can even spray inside a dog house too. It works - in fact, it killed them instantly.
Now these are good Mosquitoes!!!
