How long do gnats eggs live?

Is the lifespan of larvae influenced by habitat? The solution to this query relies upon the species of gnat, their reproductive ability, and the favorability and excellence in their selected habitat.

Habitat favorability consists of things like the quality of food present, the number of meal sources, availability of moisture, which is important for their breeding, and also how safe their habitat is. Gnat infestations last if the weather is warm and there is the availability of food and moisture.

The life cycle of gnats is approximately four weeks. Female gnats keep on reproducing in the available houses or greenhouses wherein heat and temperatures are maintained. Adults stay approximately 7-10 days and deposit eggs at the wet soil floor or even in soil cracks.

The larvae take approximately 4-30 days to hatch. All the species of gnats are alive for more or less 40 days. Gnat larvae feed mostly on plant and organic things and even fungi.

This may stunt the growth of plants. Fungus gnats are fruit fly-shaped insect pests that affect the plant present indoors.
