Unfortunately the indoor Ari's soil mix contains peat, cow manure, old orchid
potting media, ect. They have been growing now at drying conditions but still
the gnats. Malathion, diazinon, and other sprays/drenches are only temporary,
cannot do with every watering. Mothballs strategically placed however, recently
have been doing the trick. Maybe some cinnamon powder ( good for those
unfortunate rots - no problem at this time) may also have insect repellant
properties.

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.
