When I returned from a trip out of town I had some flies that I thought were fruit flies in the house. (I thought DH had let the bananas either go bad on the counter or threw them in the trash and then didn't empty the trash). Anyway, after bombing twice we called a local pest control company. (The bombs took care of most them but one is one too many for me). They identified them as drain flies and explained it could be different scenarios: 1) there was a clog/slow drain somewhere in the house, the flies were "living" off the stuff there and were coming up through another drain or 2) we have a crack in our pipes "somewhere"/could even be outside and they are getting in that way. They recommended we put bleach down all the drains and then flush them with cold water. We did that but I still see a fly or two around. DH says not to worry they are probably the ones who weren't in the drains when we bleached. I'm worried they aren't going away and we "might" have an expensive pipe problem to fix. The house is less than 3 years old so I hope we don't have a crack in any of the piping.
Does anyone have any other ideas/experience in drain flies?

I did the bleach down the drain every couple of days and would use bug spray once a day. It helped but they still kept coming back.
