Gen 1.3: Dosing Insecticide

Use only insecticides that are labeled for use in automated misting systems and strictly follow label instructions in adding insecticide to the drum:
  • Example:  A 5% pyrethrin formulation, contains label language for use in Residential Backyards to “Mix 64 fl. Oz of concentrate in 55 gallons of water to yield a solution of 0.046% Pyrethrins and 0.23% Piperonyl Butoxide.”
The insecticide label will contain both recommended and maximum concentrations.  It is against regulations to mix the insecticide to a concentration that exceeds the stated limit.
Concentrations less than recommended on the label are permissible, although there is a threshold below which the material will not be effective.
