Population explosions of Sciarid and Phorid
flies defeat Oyster mushroom cultivators more
than any other competitor. Fly control measures
have ranged from simple sticky pads to the use
of pesticides, a recourse I abhor. The use of pesticides, although rampant with many "old
school" cultivators, is totally unnecessary for
gourmet and medicinal mushroom cultivation
—given a balance of preventative measures.
Bug lights should be positioned at the entrance
of every door. The bug traps I find that work the
best are those which feature a circular black

light and centrally located fan that creates a
negative pressure vortex, features which greatly

extend their effective range. These bug lights
should also have sticky pads affixed below them
that trap "fly-bys" or "near-misses". (See Figure 384). Coupled with the frequent washing
down of the growing room, at least twice a day,
population explosions can be forestalled or precluded.
There is one final control measure I recommend highly and which occurred naturally in
our growing rooms. For the past 5 years, our
growing rooms have sustained a population of
