No offense meant to Dave S who suggested BT but Does anyone have any non-toxic options to fight fungus gnats?
I assume these are the black fruitfly sort of bugs (with white/clear wings) that are everywhere currently in my terrariums and seems to be coming from the pots. I've been using the yellow flypapers but they continute to catch page after page of gnats. Seems like theres a never ending supply of gnats to feed the papers. They never were in there before that I can recall but I don't know what I can do about them, I'm too afriad to use chemicals on many of many things.
Can you drown the larve by submersing the pots fully in water for a few minutes or does it have to have poisons in it to kill them?
Anything I can do to ensure if I can get rid of them they don't come back?
