For a mild infestation, I would first identify the wettest pots, let the upper layer dry as far as each plant safely tolerates, improve drainage, and remove standing water. Then use a label-approved larval treatment such as Bti or Steinernema feltiae nematodes if the problem persists. Repeat on the product's stated interval so the next generation is caught.

I would not automatically bare-root and repot every plant, because that can add root stress and does not address adults moving between nearby pots. Likewise, systemic insecticide is best reserved for a labelled need rather than routine prevention, especially around edible plants, pets, and outdoor pollinator access.

I work on KnowYourPlant, and our fungus-gnat guide explains how to match each control step to the egg, larval, and adult stages: https://knowyourplant.app/blog/posts/fungus-gnats-houseplants/

Keeping a simple weekly count on one sticky card per plant group makes it much easier to tell whether the plan is actually working.

I have cinnamon socks on hand. How fine does it need to be or can I just stick them in the soil?

I’m so glad I found this on fungus gnats! I don’t have a huge infestation but I have tried reporting plants even 2-3 times and they still gnats come back. I cannot find gnat nix anywhere and I also can’t find horticulture sand. What can I use as a substitute for those that is effective as well? Would perlite work? I also use moss so that the gnats don’t lay eggs but it’s a little harder to use moss in a pot with pothos. I have also tried mosquito bits ( diluting in water per company and then using that water but some of my plants like the snake plant don’t need water but once a month, or my Zz plant. Do you have any other suggestions? Would greatly appreciate it! Thank you
