Fruit Flies are 1/8 to 1/5 of an inch long and yellow-brownish in color. Some species have reddish-colored eyes. The larvae are about 1/10 to 1/5 of an inch in length and are identified by the stalk-like breathing tube extended from the tail end of the body. Each female can lay up to 500 eggs which will hatch in about 24 hours. They are associated with fermenting or over-ripened fruit or other foods and will breed in areas such as the bottom of a garbage can or a wet mop.
