Fungus gnats are attracted to light, so they can usually be found flying around lamps and windows. To successfully get rid of fungus gnats for good, you need to know something about their lifecycle. The fungus gnat’s life cycle is about one month, and will continuously reproduce in homes with warm temperatures. Larva - There are 4 larval stages, characterized by a black ‘head capsule’. Fungus gnat adults are weak fliers, typically flying in short, erratic patterns. Fungus Gnat Biology and Life Cycle. Adult fungus gnats are small (1/8 inch long), black-gray flies with long legs, many segmented antennae and a single pair of grayish transparent wings with a Y-shaped vein near the wing tip. Life Cycle of Fungus Gnats. Fungus Gnat Life Cycle. In homes, they usually are seen in the near vicinity of an infested houseplant. Lifecycle of a Fungus Gnat: The lifecycle of a fungus gnat can be divided into four stages – egg, larva, pupa, and adult. Figure 2: Fungus gnat life cycle. What's nice is the adult fungus gnat only lives around one week, but in that time they can lay up to 300 eggs each. The larvae feed on root hairs, the stems of unrooted cuttings, and organic material. Life Cycle of Fungus Gnats The fungus gnat life cycle has 4 stages: Egg - Eggs are laid by adult females into the cracks and crevice of most soil, not directly on the soil surface. Fungus gnats reproduce in moist, shaded areas in decaying organic matter such as leaf litter. They complete their life cycle in about four weeks depending on temperature and other environmental conditions. Life Cycle. The Diptera are insects that metamorphose, or alter shape, completely. Female fungus gnats deposit their eggs on the moist soil or decaying matter. Fungus gnats develop in moist, often-shaded areas in decaying organic matter such as leaf litter. The breeding and reproduction patterns are reasons to eliminate gnats as soon as possible. The gnats have a quick lifecycle and multiply prolifically. The fungus gnat life cycle is quick, and they can quickly take over your entire interior plants if they are left untreated. The adults themselves generally do little harm; it is the larvae that do the damage. These eggs hatch into larvae in about three days. Female, adult fungus gnats will lay up to 300 eggs in on the surface of the moist soil or in the soil cracks. With a life span of about four weeks from egg to adult, each female can lay 200 to 300 eggs and cause havoc all year. > Life cycle and general description of fungus gnats. The life cycle takes about four weeks under normal spring and summer weather conditions, but it is in continuous reproduction in homes or greenhouses where warm temperatures are maintained. Adults are weak fliers and often found near light sources or along the soil surface. In about 4-6 days these eggs hatch into larvae and begin snacking on the roots of your plants in the moisture rich soil. Adults emerge about one week later. Fruit Flies Most of the fungus gnats are female and can lay up to 300 eggs in the crevices of the soil, and the fungus gnat eggs will hatch into larvae within six days.
