How to Manage Pests

Pests in Gardens and Landscapes

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.
