Fungus gnats have four developmental stages. Within 4-6 days tiny larvae emerge and begin feeding on plant roots during their two week lives.

How To Get Rid Of Fungus Gnats On Houseplants Garden Fundamentals

Adults live for about another week and a half during which they produce up to 300 eggs.

. Depending on the temperature the eggs hatch in about 5 days the larvae will emerge and begin eating to gather energy to fuel their transformation into adulthood. In most cases especially indoors fungus gnats are harmless. Fungus gnats grow through four life stages- egg larvae pupa and adult and produce many overlapping generations in just one year.

Fungus gnats develop through four stages. The first stage is to remove the larvae and THEN the airborne specimens. The pests favor high temperatures making greenhouses garden centers and plants in heated homes popular sites for.

The pests produce several generations each year and dont require much time to mature. The life cycle is about four weeks with continuous reproduction in homes or greenhouses where warm temperatures are maintained. Adults live about one week and lay up to 300 eggs in rich moist soils.

These eggs hatch into larvae in about three days. Female fungus gnats deposit their eggs on the moist soil or decaying matter. Fungus gnats living in the soil often travel indoors on potted plants or cut garden flowers.

The females deposit eggs in the surface layer of the potting compost and these hatch within a few days under warm conditions. 132 long into moist soil. The tiny eggs and oblong pupae occur in damp organic media where females.

At 70 -75 F these whitish-yellow eggs hatch in 3-6 days. The adult female fungus gnat will lay more than 200 eggs in damp soil. The larvae feed on the decaying organic matter but in some species they also feed on the plant roots.

Adult females lay about 200 transparent eggs each about 1 mm. Fungus gnats quickly go through four stages of development. In homes populations quickly grow out of hand.

Adults live about 7 to 10 days and deposit eggs on the moist soil surface or in soil cracks. The lifecycle of a fungus gnat can be divided into four stages egg larva pupa and adult. Ft can be found.

Fungus gnat larvae require 3-4 weeks or more. This entire life cycle can occur in a single potted plant hosting several generations at once. Life Cycle and Description.

The whole life cycle from laying of the eggs to adults dying off of old age takes place in 3-4 weeks total with the range changing depending on the local temperature. Adult females deposit 30 to 200 whitish-yellow eggs singly or in clusters in crevices or cracks on the surface of growing media and in moist organic debris.

After 3-7 days in the pupal stage adults emerge and live for up to 8 days. They deposit the eggs directly onto food sources like damp plant soil. Raymond Cloyd Kansas State University.

At 75ºF eggs hatch in about 3 days the larvae take approximately 10 days to develop into pupae and about 4 days later the adults emerge. Although adult fungus gnats only live an average of 10 days females lay approximately 150 eggs in their lifetime. One female gnat can lay up to 1000 eggs during its lifetime.
