It was introduced in 1949 as first synthetic pyrethroid. It is a mixture of several isomeric forms in which the most common form is a 4:1 mixture of the trans- and cis-isomers. D-trans allethrin is usually combined with synergists such as piperonyl-butoxide to increase the toxicity. Allethrin metabolized by a hydrolytic pathway followed by oxidation and dehydrogenation.

Mode of action: Lindane is stimulants of central nervous system, with the principal symptom being convulsions.  Breakdown in soil and groundwater: Lindane is highly persistent in most soils, with a field half-life of approximately 15 months. When sprayed on the surface, the half-life was shorter than incorporated into the soil. 4.
