Subject: Re: Fungus gnats
Fungus gnats are common in places that stay too moist and damp and have lots of
decaying vegetable matter to feed their larvae. Your first course of action
should be to remove the conditions that are allowing the critters to breed and
thrive, improve santitation under benches etc. If this doesn't help then go to
the heavy duty insecticides, Dursban etc.
