  • Step 2: For proper ground application, mount the fog applicator so that the nozzle is at least 4 ½ feet above ground level and directed out the back of the vehicle. May be applied at speeds of 5 mph up to 20 mph.
  • Step 3: Begin treating the infested areas where the flying pests gather to knock them down and keep them away.
