How is malathion applied?
A. Malathion is applied by licensed applicators using a truck mounted Ultra Low Volume (ULV) applicator. The ULV fogger produces droplets that are from 7 to 30 microns (one millionth of a meter) in size. The ULV fogger droplets effectively travel up to 90 meters from the truck and kill any mosquitoes that they come in contact with. Health Canada limits the amount of malathion used to 60.8 g/ha.
