Summary

One of the most frustrating pests in many indoor gardens is the dreaded fungus gnat and its young, the fungus gnat larvae. These little buggers can absolutely destroy your plants if you’re not vigilant — and they can do it quickly. The primary way that fungus gnats affect your plants is through their larvae. They lay eggs in your growing medium. Once they hatch, the larvae will attach to the roots of your plants and drain them of nutrients. Although the larvae are the main negative actors, adult fungus gnats can carry disease, especially fungal diseases.​ These can be deadly on their own, but that’s not all. They also lay hundreds of eggs fast, which will devour plant roots! It’s absolutely essential that you stop these pests before they can take hold, whether indoors or out. The last thing you need is for your plants to succumb to a horrible fate. I’ll help you to overcome your fungus gnat woes, though. Let’s go into detail about fungus gnats and their larvae, and learn how to demolish them before they can take over!

Fungus gnats. These are really annoying and they can absolutely destroy your plants if you're not vigilant and they can do it really quickly.

larva like many other pests in the garden.

medium and then they hatch and then those larva are going to attach actually

0:26.9

to the roots of your plants and then drain them of nutrients and then eventually

0:31.6

kill the plants.

0:34.1

So they're called fungus gnats because the adult gnats

0:37.2

carry fungal diseases, which will also harm your plants.

So it's kind of like a double whammy. The adults are

to put out we like to talk about the life cycle because if you

1:04.8

can disrupt the life cycle and there's various ways to disrupt in each stage of the life cycle,

1:11.0

then of course you are destroying that pest's ability to reproduce and that's what we're trying to do.

1:16.0

So, what is the life cycle of a fungus gnat?

1:19.0

Well, there are four stages. There's the egg stage, the larva stage, the pupa stage, and the adult stage.
