Pour about 1/2 a cup of balsamic vinegar or any other sweet liquid into a large shallow bowl---think "what would a fruit fly like" even a few pieces of fruit would work. Cover very very tightly with plastic wrap making sure it is completely covered. Poke 10-15 holes with a toothpick and set out on the counter. Come back later to a bowl full of drowning fruit flies. They fly in but are not smart enough to fly out. Worked like a charm.


I'm thinking 4th grade science fair with this one!!!

very cool- very gross
We had that problem after we got back from vacation this summer. I am just as genius as you and I googled it too! We used a water bottle and taped around the opening so it was smaller and they couldn't get out either! So smart, you are!!
