Tetramethrin is a broad-spectrum, first-generation synthetic pyrethroid insecticide. Pyrethroids are synthetic esters derived from naturally occurring pyrethrins (insecticides derived from the extract of chrysanthemum flowers). Tetramethrin is a rapid knockdown agent against flying and crawling insects.
The primary target pests are flying and crawling insects such as wasps, hornets, roaches, ants, fleas, and mosquitoes.
Tetramethrin is applied by aerosol can, handheld sprayers, foggers, and mechanical sprayers.
There are no human health risks of concern for tetramethrin, and therefore, no risk mitigation is necessary. The personal protective equipment (PPE) for all occupational handlers is baseline (long-sleeve shirt, long pants, and shoes plus socks), and the re-entry interval (REI) is 12 hours.
Do not apply directly to or near water, storm drains, gutters, sewers, or drainage ditches. Do not apply when windy. Do not water the treated area(s) to the point of run-off or apply when raining or when rain is expected that day. Rinse application equipment over treated area only.
