Without a doubt, fungus gnats are very destructive greenhouse 
pests.  I have seen the carnage myself across countless 
species.  Much time and effort is spent on their control.  Not all Bt 
is the same.  Bt products like Gnatrol that specifically target 
fungas gnats and other closely related insect species have been 
available since at least the 1980's.  I believe that other strains of 
Bt have since been isolated that target other insect groups.

Also, "both larvae and adults can spread plant pathogens and may 
promote disease in commercial crops."
