The gas they use nowadays is Sulfuryl  Fluoride.  It used to be Methyl 
Bromide but apparently MB is bad for the atmosphere so they stopped 
using it.  Methyl Bromide left zero residual.  You could use it in food 
processing plants.  The same is supposed to be true of
sulfuryl Fluoride, it completely aerates and is gone.  SF is also used 
in mills and processing plants.  Imagine flour going buggy.  fjm
