Fruit Flies

General Descriptions
Also known as vinegar flies, fruit flies are attracted to sweet or fermented liquids such as liquor, syrup, soda pop and vinegar, in addition to ripening/rotting fruit. Females lay eggs in and around these materials upon which their tiny larvae feed. The gnat-sized adults are up to one-eighth of an inch long and typically have tan-colored bodies and red to brown eyes.


General Control
Properly storing fruits and vegetables especially during summer and early fall can reduce the chances of having fruit flies. Storing mops and rags clean and dry, and cleaning out drains, garbage disposals and trash receptacles also will eliminate fruit fly breeding sites. It takes less than a week for a fruit fly to develop from egg to adult, so problems can quickly arise.
