Fungus Gnats in Central Arkansas
The fungus gnat is a small insect with spindly legs and long wings. These gnats can occasionally become a nuisance in commercial and residential buildings where there are plants that are rich in organic matter. This organic matter is a breeding source for the gnats as the larvae feed on fungi and organic matter in the soil. They will also chew the roots of the plant, which can become problematic for nurseries, greenhouses, or other interior spaces with plants. Adults are attracted to lights and can be noticed on light fixtures or near windows.
Fungus Gnat Habitat
Indoors, fungus gnats are attracted to light and can be seen hovering near windows. However, compared to house flies, fungus gnats are weak flyers and generally remain near potted plants. They can also be found in high moisture areas in the home including, bathrooms, laundry rooms, kitchens, and crawl spaces. Outdoors, fungus gnats are attracted to moisture and problems may occur in areas where the landscape has been overwatered or in low-lying areas that remain extremely wet following heavy rainfall.
Fungus Gnat Behaviors, Threats, or Dangers
Adult fungus gnats are primarily considered a nuisance as they do not bite or damage plants. The larvae can do damage with their destruction to roots. The larvae can stunt plant growth, especially in young plants or seedlings. When there is a large presence of larvae, significant root damage and even plant death can occur. Therefore, a houseplant that is wilting may not indicate a lack of water, but rather root damage by fungus gnat larvae.
