Studies indicate that methoprene is of low toxicity and poses little risk to people when used according to label instructions. Results show that realized environmental concentrations of methoprene were usually 2-5µg/kg (range 2-45µg/kg) and that its motility is limited. We compared the efficacy and nontarget effects of temephos, Bacillus thuringiensis var. Arrives before Christmas. Juvenile hormone (JH) analogs are used to control mosquitoes. During peak seasons of mosquito reproduction, apply granules about every 3 weeks to suppress potential adult mosquito emergence. (S)-methoprene has no effect on mosquitoes which have reached the pupal or adult stage prior to treatment. ... at controlling mosquitoes in underground storm water drainage catch basins. However, both larval development and action of JH analogs are not well studied in these insects because RNA interference does not work well. Also, for freshwater fish, it is “moderately toxic” to warm water species and “slightly toxic” to cold water species. J Am Mosq Control Assoc. Many juvenile hormone analogs interfere with insect metamorphosis, a property that makes them useful in insect control and as investigatorial tools with which to study metamorphic mechanisms. They consider it so safe that humans can actually drink water treated with it, based on a risk assessment in 2007.
