If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much? Fem yes I am using fremented algae for nutrients in veg and Fox farm tiger bloom for flower and it’s indoor how do I get rid of fungus gnats

I use sticky traps and nematodes (nemaknights on Amazon) then cover with a 2" barrier or sand or perlite.

Sticky traps ans about 1/8inch of Diatomaceous earth

I use about an inch layer of sand. After a few days nats will be down to a few. Then i take sand off. Reuse later if needed.

In my latest battle against fungus gnats, I implemented a comprehensive and strategic approach to fully control this pest from all angles. Below is the step-by-step method I followed, using various techniques to ensure complete eradication of the problem:

  1. Sticky Traps:

I started by placing yellow sticky traps at the soil level. These traps are highly effective at catching adult gnats as they try to fly around or leave the soil. By reducing the adult population, I was able to prevent them from laying more eggs, significantly cutting down the infestation early on.

  1. Diatomaceous Earth:

I sprinkled a thin layer of diatomaceous earth over the surface of the soil. This powder, made of fossilized marine organisms, dehydrates and kills larvae when they attempt to crawl through it. It’s a completely natural method and doesn’t harm the plants, providing great protection for the roots.

  1. Nematodes (Steinernema Feltiae):

To target the larvae in the soil, I introduced beneficial nematodes. These microscopic worms parasitize and kill the larvae of fungus gnats without causing harm to the plants or the soil. I applied them by mixing with the watering solution, and within days, they began doing their job.

  1. Chrysoperla Carnea (Green Lacewing Larvae):

As a biological reinforcement, I released Chrysoperla Carnea larvae, also known as green lacewings. These are natural predators that feed on both the eggs and larvae of fungus gnats. I spread them around the plants, and they quickly began to take care of the remaining larvae.

Order and Combination of Techniques:

  1. I started with sticky traps to break the life cycle of the adult gnats.
  2. Then, I sprinkled diatomaceous earth to create a physical barrier on the soil surface.
  3. I introduced nematodes in the watering solution to directly attack larvae in the soil.
  4. Finally, I released green lacewing larvae to ensure that any remaining eggs and larvae were wiped out.

With this multi-faceted approach, I achieved full control over the fungus gnats, eliminating both adults and larvae effectively and without harmful chemicals.

This system not only solved my problem but also proved to be sustainable and safe for both the plants and the environment.

Hope that helps!
