Fungus Gnats

General Descriptions
Fungus gnats are delicate, long-legged flies that look like tiny mosquitoes. The larvae of fungus gnats live in moist places where their food of fungus grows. Indoor infestations can be associated with pigeon droppings and with over-watered potted plants where fungi develop. Pigeon or bat droppings can harbor Histoplasma fungi and other disease-causing organisms. Professional consultation is recommended when removing a buildup of droppings.


General Control
Eliminate fly breeding sites by locating and removing the attracting material. Moisture problems should also be located and eliminated as moisture contributes to fungal growth. Do not over water household plants.
