- Clean any dishes out of your sink and wipe your sink and counter tops down very well.
- Clean your disposal (make sure it is clear of any food scraps) and send a little bleach down all your sinks in your house.
- Sweep your floors to make sure there are no little crumbs that they can get.
- Make a trap for the remaining little boogers: fill a glass jar with fruit juice, white wine vinegar, or cider vinegar; add a little bit of vegetable oil or dish soap (helps trap the flies); cover the jar with plastic wrap and poke little holes in the top. Over time the flies will fly in and get stuck in the liquid (if you are for trapping them alive and releasing look elsewhere for tips). Each morning dump and the liquid outside and replace until you are no longer catching any flies.
Works in like 2-3 days hands down and you will feel like you aren't about to lose your mind over pesky fruit flies. Maybe one day I will learn to hire someone to come take our trash to the street while we are out of town, but until then...
