According to Dan Strickman, a senior program officer in vector control at the Bill and Melinda Gates Foundation, that is what happened with resmethrin and
allethrin, two pyrethroids used in mosquito control.
All 3 coils (FISH M (0.005% metofluthrin)) 86%, Shieldtox (0.15% d-trans
allethrin) 74%, and Tesco Value (0.3%
allethrin) 72% showed high knockdown efficacy.
If you're in an open-air stand, nothing works better than a ThermaCell, which uses butane heat to vaporize an insect repellant called
allethrin, which, according to the company, is a copy of a repellant that occurs naturally in chrysanthemum flowers.
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 butane heats a mat to release the repellent
allethrin, with each mat holding enough repellent to last four hours.
Collecting cloths were placed beneath vegetation, and then all vegetation was saturated with insecticides (Pre- Strike[TM]--active ingredients: piperonyl butoxide 1.0%, tetramethrin 0.2%, etofenprox 0.1%; Raid House & Garden[TM]--active ingredients: d-cis trans
allethrin 0.239%, 3-phenoxybenzyl d- cis and trans 2,2-dimethyl-3-(2-methylpropenyl) cyclopropanecarboxylate 0.096%).

allethrin (0.27% - 0.50% w/w) mosquito coils under a 25 m3 room experimental setup were also fairly low, ranging between 20.8 -28.3 min and 8 min respectively (Katsuda et al., 2008).
The potential of induction of mutagenicity of mosquito coil in humans is therefore a major concern, because it could account for infertility in males, as was also demonstrated by Madhubabu & Yenugu (2012) in a study of the effect of continuous inhalation of
allethrin based mosquito smoke in the male reproductive tract of rats.
allethrin, bioallethrin, tetramethrin, phenothrin, resmethrin, bioresmethrin, kadethrin, permethrin, cypermethrin, fenvalerate, deltamethrin and flumethrin.
"Type-I"-like pyrethroids include
allethrin, bifenthrin, permethrin, phenothrin, resmethrin, tefluthrin and tetramethrin.
