I'm having trouble with fungus gnats in one of my isopod containers. Whenever I replenish the humidity in that container they have an population explosion, but I can't let the container get too dry since that's going to kill my isopods.
Does anyone have a solution for this that's not going to be harmful for my isopods?
down't over water, and use Bti (such as Gnatrol, as u/Golfnbrew noted). Bacillus thuringiensis var. israelensis (Bti), a highly selective biological pesticide that kills damaging larvae, yet is safe for fish, wildlife, humans, and non-target species. They contain no harmful residues, unlike other insecticide options on the market.
