Fungus gnats - Mosquito Bit Tea \& the sticky traps

70% Isopropyl Alcohol. Contrary to popular belief, it doesn’t harm plants.

I am also having a knat problem and have seen this as a solution online, do you mix with any water or straight alcohol??

Straight! It’s kills them instantly!

Yellow ( to be specific, they like the yellow ones the most) sticky traps.

a sprinkle of cinnamon on the soil will kill the larvae :)

Death Drops from Happy Happy Houseplants. Also Knock out Gnats. I also use the Zevo lights they kill the adults
