Photograph of Propoxur under the microscope

Propoxur is a non-systemic contact insecticide that has, in effect, replaced DDT in the control of black flies and mosquitoes. This pesticide is one of the most effective carbamates in it's diversity of applications. It is active against mosquitoes, flies, fleas and ticks on pets, ants, cockroaches, aphids, leafhoppers, and even snails. Propoxur has longstanding residual activity when it is in direct contact with the target pest. Like other carbamates, propoxur blocks the production and action of cholinesterase, thus inhibiting the function of insect nervous systems. These materials act quickly to paralyze the neural transmissions in insects producing a rapid "knockdown" effect.
