It occurs to me to wonder about pressure differences. If you are spraying a pressurized fluid/compressed air mixture, does it create an explosive decompression for the bugs when they emerge? I don't think it's a problem or Elaine's users would have observed it.

I believe that, on one of Elaine's posts, she did indicate that explosiveness, or intense impact,  when the spray hits the leaves, definitely is a problem.  A gentle meeting of spray and leaf is what's needed.  I don't remember whether or not she said anything about explosiveness on exit from the sprayer - e.g. from compression.
