Fruit flies (Vinegar flies)—Drosophila spp.
Fruit fly adults are small, yellowish or brown flies with red eyes, about 0.12 inch long. Larvae are
small, white, legless maggots that may grow up to 0.2 inch long.
Life cycle
Damage Adult fruit flies are attracted to overripe, fermenting fruit of all kinds. Larvae, or maggots, feed
on the fruit and may spread yeasts that cause souring.
Solutions
Use sanitation as much as possible when conditions are favorable
for fruit fly buildup. Whenever feasible, remove overripe
fruit. When possible, remove nearby sources of ripe fruit,
such as old citrus fruit left on the ground. |
