wut?
so those fungus gnats that came in my roots soil were from me over watering, not them leaving their dirt outside?
good to know.
the eggs of fungus gnats will not hatch unless there is sufficient moisture for them to grow, the larvae will starve if there is insufficient fungus for them to eat, and if the larvae cannot survive, the gnats will never be seen flying around, fucking and laying more eggs.
just a couple microscopic eggs can result in a swarm of gnats if you feed them and keep them moist long enough for them to reproduce.
even soil stored inside in airtight sacks under 0% humidity can host a fungus gnat infestation just days after you start overwatering.
where the first eggs come from is irrelevant, since they can fly in from outside travel on your clothing, or ride on the back of your dog to get to your soil. if you make a suitable home for them, fungus gnats will move in.
but do feel free to blame the soil. im sure the blame will eradicate the infestation and protect your plants from overwatering... somehow.
