  etc.

   Sometimes insect sprays have a "carrier" chemical.  For example, the
insect spray, "RAID," contained (or used to contain) methyl chloroform
(1-1-1 trichloroethane) as a carrier, though not so indicated on the label.
I found that that chemical by itself really stirred bees into an attack
phase.
