When heated, allethrin repellent is released into the air, creating a 15 x 15 ft mosquito-free zone.
Butane-operated, it functions by heating a small mat saturated with allethrin, a synthetic version of a naturally occurring insecticide that repels mosquitoes.
All ThermaCELL products are powered by butane cartridges which heats a mat saturated with allethrin, a copy of an insecticide found in chrysanthemum flowers.
In addition, allethrin, S-bioallethrin, permethrin, fenvalerate, deltamethrin, and cypermethrin evoke alterations in motor-related end points in small rodents evident as early as 0.
Creating a 15 square-foot zone of protection, Thermacell units operate on a single butane cartridge that heats a mat releasing allethrin, a synthetic copy of a natural insecticide found in chrysanthemum flowers.
For example, allethrin is a mixture of all possible allethrin stereoisomers, d-allethrin contains only the 1R isomers, bioallethrin contains only the 1R-trans isomers, and S-bioallethrin is enriched in the S stereoisomer of the 1 R-trans isomers (Figure 2).
Coil packages tested contained up to five double coils and listed either allethrin only or allethrin and S-2 at 1.
The type segment is further classified in to bifenthrin, deltamethrin, permethrin, cypermethrin, cyfluthrin, lambda-cyhalothrin and other pyrethroids (fenvalerate, resmethrin, tetramethrin, allethrin, phenothrin, barthrin, dimethrin, and bioresmethrin).
The metabolite 3-PBA represents exposure to permethrin, cypermethrin, deltamethrin, allethrin, resmethrin, fenvalerate, cyhalothrin, fenpropathrin, and tralomethrin; and cis- and trans-DCCA represent exposure to the cis- and trans- isomers, respectively, of permethrin, cypermethrin, and cyfluthrin (Barr et al.
The butane heats a mat to release the repellent allethrin, with each mat holding enough repellent to last four hours.
Type-I"-like pyrethroids include allethrin, bifenthrin, permethrin, phenothrin, resmethrin, tefluthrin and tetramethrin.
