Beats my idea of ordering 500 live tree frogs from a biological supply company -- and then releasing them inside of your house. LOL!!! At the moment, we've got a problem with weevil moths (the kind the grow in some wheat product and then proceed to take over your house). We've found that spritzing them with orange oil cleaning spay kills them pretty quickly. Dunno if it'll work with gnats, but I thought I'd mention it. I agree on the fly paper, by the way. It's not very pretty but it definitely gets the job done. Hang it where there are lots of the nasty flying things. Works a treat. Good luck with your gnat problem. bonni
