How do you get rid of fruit flies?

I always would use a vacuum cleaner wand. Suck ‘em out of mid air flight.

Lucky for you they go a way really fast (generally within 24 hours) if you get rid of any source of food. Empty all the garbage cans, wash your dishes, and toss out any beer cans and they will be gone quickly.

Killing them is pretty much a endless thing unless you get rid of why they are there in the first place.

Get rid of fruit and other food. They’ll vanish.

After getting rid of the rotting food, make a fruit fly trap.

In addition to a fruit fly trap, here are nine other tips.

I second the trap suggestion. When I make them, I don’t use vinegar, though, as I haven’t had great results with it. The best thing is a piece of the spoiled fruit, or a bit of fresh fruit if you don’t have any gross stuff anymore:-) They will also go after wine, so a small amount of that works. I make my traps by taping an inverted paper cone in a jar(leave a small opening at the point of the cone!). They will also go after corn; I have a parrot who I give some thawed-out frozen corn every day, and if there are fruit flies around, that’s always the first place they show up.

As the founding member of the Fruit Fly Defense League, I must protest the mass murder of my friends and colleagues. What you are advocating is nothing less than the extermination of my entire species! And that cannot stand.

If you proceed in the mass murder of fruit flies, I warn you – those of us that survive will come back in even more force.

Seriously, get rid of the fruit and clean the area (with soap) – the flies will disappear.

I fill a shot glass about ¾ of the way full and then stir in a couple drops of dishwashing liquid. When they try to land, they sink through the dish liquid and drown in the wine. They can’t get out. I’m currently doing this now.

Apparently they love bananas more than me. Bastards.

What @johnpowell said. Fruit flies have a famously short life cycle, which is why they are so often used for genetic research. Completely cut off their access to their food source, and they will die out within a few days. Seal your food in airtight containers; clean up after yourself when preparing food.

I had a link on another question about yellow jacket bees that I bet would work here, too. Using a knife, cut just the portion above the label off of a pop or water bottle. Put ½ inch or so of wine in the bottle, then add a few drops of dishwashing liquid. Invert the top back on the bottle to make a funnel. If that hole proves to be too big, you can narrow it with paper or plastic.

Do we all know Fluther has a search feature to find past answers?

Se in would be too extreme in this case ;) best luck has been with the traps as mentioned above. I would also deploy a flypaper strip early on to catch the swarming ones waiting their turn to drown. Luckily, the banana fiend is now away at school, so haven’t had much of a problem this year.

A bowl with some yeast and water. Cover with saran wrap and poke a few holes. They will get trapped inside and can’t come out.

Let a couple tree frogs and Geckos loose in your house. Every house needs a frog and lizard for fly control. lol
Over here we have scads of little pacific tree frogs that are everywhere, few insects survive their stealth.

These traps will certainly kill a lot of fruit flies. That might make you feel better, but will not really solve the problem. You need to remove their food and breeding grounds if you want to rid yourself of them for good.
