Default After 5.5 weeks I'm getting fruit flies in my airlock..

6 gallon batch of apfelwein near completion, is attracting fruit flies and they are committing suicide in the Star San in the 3 piece air lock.....

Should I clean 'em out or just leave 'em in there for another week or two....

Do you have a cap on the top of the airlock?

Clean it out, replace the star san with cheap vodka. Don't worry, the apfelwein will be fine.

Drowned fruit flies in the airlock aren't bad, drowned fruitflies in the apfelwein are.

Clean 'em out if it makes you feel better, but I'd address the source of the fruitfly infestation before you start making vinegar instead of beer and apfelwein. Acetobacter is a nasty bug.

If they can't get in from the top of the lock (through the plastic), then there is really only one answer: the fruit flies are coming from INSIDE THE HOUSE, er, CARBOY!!!

It's funny, I am not afraid of spiders or rodents (not that they are running free in my home) but I live in total fear of the threat of fruit flies. I've stopped buying fresh pineapples because I don't want to introduce them to my yummy beer.

If I ever see a tiny flying thing in my house I go on a cleaning spree. Get rid of trashbag. Lysol the trashcan thoroughly and disinfect the air and surfaces in my kitchen. An ounce of prevention is worth a pound of the pain in the ass of getting rid of an active infection inside my beer brewing equipment.

I had fruitflys in the fall. I had apparently put some bottles away that I hadn't rinsed (stupid) and that became a breeding ground for them. I ended up having 2-3 glasses around the house with a vinigar/water/drop of soap mix that would drown them. Eventually after I found and cleaned up my bottles the fruit flies all died. I also bleached all my drains.
