Fruit Flies

What do fruit flies look like?


Fruit flies are a small species of flies, with adults measuring only about 1/8 inch in length. They are known for their red eyes, although some may have brownish or black-colored eyes. Their wings are translucent, while their bodies are usually black on top and gray on the underside, appearing tan to the human eye. 

Fruit fly larvae are worm-like in appearance and about 1/4 to 3/8 inch long. They are whitish in color, except for the two dark-colored mouth hooks.

What attracts fruit flies?

During spring and summer, fruit flies increase in numbers and reach their peak during the fall harvest season. These small flies are attracted to ripe, decaying, or fermenting food and lay their eggs on them. 

They commonly infest garbage, compost piles, and garden areas. However, fruit flies can also become a problem inside homes and businesses, especially when foods that are already infested with fruit flies or eggs are introduced. This may happen with fruits, vegetables, improperly sealed jars, and cans.

Where do fruit flies breed?

In addition to the breeding sites mentioned in the previous section, fruit flies can also breed in drains, garbage disposals, trash cans, mops, cleaning rags, and inside empty cans and bottles found in homes and businesses.

Are fruit flies dangerous?

Fruit flies are primarily nuisance pests. However, they also have the potential to contaminate food with bacteria and other disease-producing organisms. That’s because these small flies pick up bacteria on their bodies and legs as they travel, breed, and feed. Unfortunately, the places they visit aren’t all that sanitary. 

How do I get rid of fruit flies?

In order to get rid of a fruit fly infestation, it is necessary to identify all breeding sites and then eliminate or thoroughly clean them. For commercial facilities, treatment may include drain bio-remediation.
