Janet McAllister, a CDC medical entomologist and advisor on mosquito abatement efforts in Miami, says the agents used for mosquito control alternate between pyrethrin
and pyrethroid insecticides and various organophosphates, including naled, malathion, and in vary rare instances chlorpyrifos.
Some bed bug populations have become resistant to pyrethrins

moved significantly greater horizontal distances compared with the untreated control, during the first 10 min of insecticide exposure (P < 0.
Permethrin and pyrethrins
paralyze lice by modifying voltage-gated sodium channels, so that resistance to one agent usually confers resistance to all of them.
are present in pyrethrum extracts obtained from flowers of some species of chrysanthemum.
The synthetic pyrethroids and their natural pyrethrins
can be divided into two groups based on their chemical structures and mechanism of action on insect target sites.
Yard Net Granular significantly controls biting insects such as mosquitoes, fleas, ticks, black flies and gnats, but unlike many "backyard" insect repellents, it contains no pyrethrins
