I got tired of the little gnats and flies appearing out of nowhere every time I start baking. So I did some research and gave this light a try. It caught nothing but gnats the first couple of weeks. Then 3 days ago I saw a fly and couldn't wait for its capture. Well 2 days later I'm still seeing this fly, upset I went ahead and killed it. When I checked the trap to see if I got anymore gnats, I saw 2 flies and that spider flying looking bug. It wasnt the same fly and got so excited that I'm no longer chasing down 3-5 flies EVERY time I bake.
