Fungus Flies

Fungus flies are widespread indoor pests that look like mosquitoes but don’t bite and are frequently found around plants. The larvae feed on roots, root hairs, fungus, and other organic material in wet, rich soil. Fungus flies are so minute that you might not see them unless they swarm. They are sometimes mistaken for fruit flies due to their small size. Adult flies measure approximately 1/8″ long, have lengthy legs, antennae, and one pair of wings, and are grey to black in appearance. Each larva is 1/4 inch long, with a pale or translucent body and a gleaming blackhead.

Habits

Adults may lay up to 300 eggs in rich, wet soils and survive for approximately a week. During their two-week lifespan, small larvae emerge within 4-6 days and begin feasting on plant roots. Before young adults leave the earth and begin the next generation, the pupal stage lasts 3-4 days. Depending on the climate, the full life cycle from egg to adult can be accomplished in as little as 3-4 weeks. Potted plants may host each stage — egg, larvae, pupae, and adult — in numerous generations at once because of their propensity and relatively brief gestation.

Habitats

Fungus gnats spend most of their time on the soil surface of potted plants, although they can also be spotted flying around the pot’s outside edge or near drainage holes. Because they are not strong fliers, they prefer to wander along the ground and only fly in brief spurts. Their flight pattern is irregular, and they are much slower than fruit flies, resembling mosquitoes in flight.

Threats

Because adult fungus flies do not bite or feed, they pose no hazard to humans or plants. However, if they are not regulated and allowed to breed in great numbers, they may become a nuisance. Fungus flies’ larvae are a minor hazard to young plants. Larvae usually feed on organic materials present in the soil, as well as the roots of indoor plants on occasion. Because the roots of seedlings and other less-established houseplants are so sensitive, they are particularly vulnerable to injury.

Prevention

Fungus gnats lay their eggs on decaying organic materials, which are abundant in plant detritus. As a result, it’s critical to keep detritus like fallen leaves, blooms, and fruit out of the soil around your plants. If you have fungus gnats surrounding your houseplants, use a potting mix without composted materials such as processed forest products, bark fines, or real compost.

I contacted GTA Pest control on a Thursday 7 PM before the July 1 long weekend and they were kind enough to accommodate me an appointment next day (Friday) which was so appreciative. The exterminator came on time and did the job well. Issue is resolved now. Thanks to Sidra and her Team in GTA Pest Control.

I’ve been using this company for 6+ years now. They always do a great job so I have them come out every couple of years to do treatment in the house to keep those mice away! The joys of living near a ravine.

They were so organized and helpful when I called to book an appointment. And the person who came to our house to spray the wasp nest was very competent, knowledgeable and kind. Thank you!
