Mosquito control program. This program involves the use of an ultra-low volume ground sprayer dispensing chemical in smoke form. It is an insecticide that is a synthetic compound resembling a substance produced by chrysanthemums, to reduce the mosquito populations. The insecticide resembles naturally occurring plant products, which are toxic to insects. This insecticide is among the least harmful products available, breaks down rapidly in the environment, and poses almost no risk to people and pets in the concentrations being used for mosquito control. Insecticides of this type have been used primarily to control mosquitoes, human lice, cockroaches, beetles and flies.
