Pests.

Fruit Flies . Two things i have done that worked:
1. If you have wine in the house, pour a small amount in a short cup overnight, they will come to it and drown.

2. If you don't want to waste good wine on bugs then use a small amount of apple cider vinegar. Like i said this worked for me. -- Elsa Miles
