Fruit Fly Trap - cooking recipe

Ingredients

1/4 cup apple cider vinegar
1/2 cup boiling water
2 teaspoons sugar
1 -2 drop liquid dishwashing soap (not odor eliminating)

Preparation

Boil water in the microwave and add sugar. Stir until dissolved. Add vinegar and dishwashing liquid. Stir gently.
Whenever we bring home fruit or fresh produce, I make a trap and place it right next to it.
As they start to evaporate, I add a bit of water and a drop of dishwashing liquid to each trap once a week or so. I replace each trap every two weeks with a fresh one during peak fruit season.
FYI:
I have found placing this solution in a see through bright colored bowl (such as the disposable children's travel bowls) works best. I also place it on a small plate to catch any spills, as this gets sticky. Fruit flies are also attracted to light -- so placing in your window sill is a good choice. In addition to the obvious fruit they are also attracted to trash, dirty dishes, and diapers.
