Fungus gnats don’t eat the leaves, they will feed on the roots, but you would need a Sever infestation for them to start affecting the plant health. Fungus gnats are just annoying as hell, plus if you have them in flower, they will get stuck on trichomes on your buds.
The only way to stop fungus gnats is to use multiple methods. The goal is to break the life cycle, so you need to kill the adults AND the larvae in the soil.

Yellow sticky traps… Everywhere. Lay the sticky traps on the soil, put them all over the place in your grow environment.

If you are not using living soil, you can use Very Little hydrogen peroxide mixed into the water. It will not harm the plant, but it will kill the larvae, flies and bacteria. I use this product Hydr-ox: https://greenplanetnutrients.ca/product/greenplanet-nutrients-hydr-ox/

After you have fed water with some hydrogen peroxide, you should add in beneficial bacteria. Like Fish Sh!t and or Microbial Mass Pro.
