Fruit flies are named for their tendency to lay their eggs on fruits. They are a nuisance as well as potential disease carriers. Fruit flies are tan to brownish yellow to brownish black, and measure up to 1/8 of an inch long. They are attracted to fresh fruits, vegetables and decaying organic matter. To get rid of fruit flies, it is essential to remove their breeding site. If they are entering from outdoors, smaller mesh screens and baited jar traps can be used. In other cases pesticides can be used, after which the area should be kept thoroughly sanitized.
