Salt soaps are quite effective as contact insecticides, and can work as 
nerve disruptors, not unlike insecticides,  when an insect is sprayed 
adequately or dipped in a soap or sticker solution. Look up "Baldwin & 
Koehler; Soaps and Cockroaches", or something like that.


  I would think it difficult to cause colony level mortality from 
spraying field bees with a Soap or Sticker solution.
