...kills flies. I don't know how they got in with all the windows closed, but about 20 flies were in my house when I got home today. I hate flies in the house and I'll obsess until I kill them all. They're all on the windows trying to figure out how to get out. I had some in the kitchen and didn't want to use bug spray near the counter so I blasted them with some 409, since it was sitting nearby. To my surprise, it toasted them. Just thought I'd share, for those that don't like to use poison in the kitchen.
