Comments - How To: Make the Ultimate, Reusable Fruit Fly Trap

Amie on Apr 05, 2015:

I had those meal moths. I didn't know it because they were in a cabinet I hardly ever went into. They got bad, and then the brown widow spiders set up shop to eat them. It was not fun trying to get rid of those, let me tell you! From now on, all grain stays in the freezer.

after doing some resesarch, i decided on filling a mason jar with regular vinegar, a splash of dishwashing soap, and a slice of ripe banana.  Before I could even get the cling wrap out of the cupboard, the fruit flies were already swarming! It seems to me that as long as there's only one tempting thing in the room (you've cleared any fruit off the counters, taken out the trash, etc) anything fruity or fermented will attract them....you just need to find a way to make them stuck there! thanks for the tips!

I just stopped at the local hardware store for a project, and saw a commercial fruit fly trap under the trademark name "Terro." With a retail price of near $10, I was determined to figure out what the liquid was in the small 1/2 ounce vile that came with the physical plastic trap; looks like a small apple. As soon as I poured the red liquid into the trap, I smelled the liquid. APPLE CIDER VINEGAR! Then I found this site, and it was confirmed. Seems that a commercial manufacturer would use the most effective and safe product, (liability issues, right?). So now, I'll start manufacturing similar traps around our house. Thanks to all the contributors for the additional input.  best from Al in SoCal.

I found they love used coffee but could not trap them.  Added used coffee beer and a drop of dish fluid and works great.   They all swarm right in there.

Just set up a trap with orange juice in it. C'mon you little monsters, I want my room back.

hey JO, Balsamic Vinegar works SO MUCH BETTER than Apple Cider

You don't even need a lid. Just pour a little cider vinegar in a small bowl and add a couple of drops of dishwashing liquid. any brand of vinegar and soap works. The fruit flys like the vinegar, go in, and the soap drowns them. It really works.  I had the little moth like things in my pantry, and so did my sister. I ended up having to dump anything dry, even if it was packaged, then clean the pantry thoroughly. It's the only thing that works.

Apple cider vinegar and a drop of dishwashing liquid works better than ANYTHING!

Moths and their larvae can be killed by putting your flour, rice, pasta etc in the freezer for a few weeks. They can't survive the cold temperatures. We had a big problem with the little buggers and freezing works every time!

Has anyone tried this for gnats?


 


Lea on Aug 05, 2012:

I have also used a white bowl with water and a drop or two of soap under a night light.

I set up two jars, one with beer and one with apple cider vinegar. While many have said here that beer works for them, in my test the vinegar had clearly won out. Who knows maybe its because of location? I don't know. But those fruit flys we definitely diving into this jar and NOT getting out. I also kept moving the jar in different locations to get the stragglers. Thank you so much for this great idea!!!


DebP on Jun 26, 2012:

Patti,I don't think this works on the moths.  We had a problem a couple of years back with the moths.  I think they came in with some flour we got.  Put all your open items in a plastic baggine or some kind of plastic container.  I put the hose attachment on our vacuum and everytime I saw a moth or a larva, I sucked it up in the vacuum cleaner.  It took a little while, but no moths anymore


Patti Gambori on Jun 26, 2012:

I have these nasty little mothy things in my pantry (maybe from cereal or something). Does anyone know if this will work on them?  I think I will try it anyway and comment on whether it does. Or do you have an idea that will get rid of these  mothy fly things?  Thanks for your help.


Deb on Jul 15, 2011:

The juice/vinegar left in the pepperoncini jars makes great bait and kills fruit flies.  We learned that quite by accident.


Jena on Jun 22, 2011:

I always use cider vinegar (and it definitely matters which brand you use, 'cause the generic store brand has never worked as well as, say, Heinz), dishwashing soap, and a paper cone, which works like a lobster trap--they can get in but they can't get out.


the actor's diet on Jul 22, 2010:

i've done this with apple cider vinegar and it works pretty well, but i like the beer idea!  thanks!


Avi on Jul 22, 2010:

If you don't want to make holes on a lid for use later, I always use clingfilm and make little holes and wrap it tightly around the top of the jar. Works a charm!


Chris Gardner on Jul 20, 2010:

Sure - you'll see in the post above that fruit juice or apple cider vinegar can also work.


Love Me Some Beer on Jul 19, 2010:

Is there any way to do it without wasting beer?!?!?!?!


alicia on Jul 19, 2010:

Awesome. Awesome. Awesome. Thanks for the great idea. Our kitchen's happy troop of fruit flies are killin' me this summer.


Chris Gardner on Jul 16, 2010:

Thanks for the great idea, Mo! I'm headed to add a drop of soap right now!


Mo on Jul 16, 2010:

If you add a single drop of dishwashing liquid, the surface tension will be broken, and the flies will drown immediately without getting a free meal first.  (I've cleared a cloud of flies in less than an hour.) The soap also seems to make vinegar work best, and it's definitely less smelly than beer sitting in a warm kitchen after a few days.  Happy killing!
