Catching Drosophila melanogaster


Fruit flies.

We put apple cider vinegar in a small container and set the container(s) where we want to catch the flies.

Quick, easy and effective.

I need to give that a try, been plagued by them b/c I always buy too many bananas.

I have had success with a 16 oz. or liter empty soda bottle, cutting off the top - like a funnel - and after putting in a piece of banana (or just the peel), stapling the upside down "funnel" to the larger part. They fly in but most don't fly out. I don't drink much pop, so I ran out of those quickly.

After you posted this this morning, I went and read about them (after having one fly up my nose), they're also called "vinegar flies" - I did not know that!

The fruit flies get in the vinegar and drown.
