Desirability of three synthetic pyrethroid aerosols for aircraft disinsection*

Of several aerosol formulations of 3 synthetic pyrethroids, S-2539 Forte, resmethrin, and bioresmethrin, the 2% formulation was most effective for the disinsection of passenger spaces aboard jet aircraft; the 1.2% and 0.3% formulations were less effective. Break-off tip aerosol units gave good dispersal, but these limited production cans showed slight variability in the rate of release.
