For some reason I hold gnats in my kitchen and within one of the bedrooms. My house is spotless I cleaned from top to bottom yesterday made sure there wasn't any spoiled food around and I do not hold any fruit.. Where are they coming from and what can I do to get rid of them?!?! They are really getting on my nerves. HELP!!

Answers:    Shut adjectives doors and windows - spray near insect repellent go out for a few hours and come subsidise and air the house. On a personal plane...when I was a kid the little critters used to drive me nuts but never my Aunt. She used to wear Au de cologne. So one evening when I go onto the hills to pick some blackberries , she put some of her au de cologne on me. I smelt similar to a girl, but didn't get bitten at adjectives. So the old fashioned au de Cologne will at least possible give YOU some personal respite from the horrible little critters. If you don't mind smelling outdated fashioned.
