My house is infested with little tiny fruit flies (I think that's what they are). It started out with one or two here and there and now it's just ridiculous. I certainly do not live in filth, as a matter of fact, we just had a new baby, so I've been very particular about keeping the house clean. I've checked every corner of every room, closet, etc. and have not found the source. Could they be coming from rotting wood? I have a feeling the floor underneath the tile in our bathroom could be a little rotten although it's not very obvious. I live in Canada and there is no snow on the ground here in Edmonton, Alberta yet but it does dip a little below freezing at night - aren't the bugs supposed to be gone by now?! Help!
