you dont think the words Decarbomethoxylated JW062 and JWHxxx look similar to you? ok, lets get technical, (using my non technical lingo) the chemical itself is significantly, and practically non toxic to mammals, birds, fish and insect etc, however, the chemical it metabolizes into; Decarbomethoxylated JW062 (DCJW) is highly toxic. also, the enzymes that metabolise indoxicarb into DCJW are only found in insects and a few other creatures so it remains a low toxicity chemical to non target species. the mammalian body and i assume fish and birds and that do a much better job at filtering, metabolising and otherwise deposing of chemicals like these then insects. also, if the chemical finds it way to the nerves and such at high doses, enough to effect the function of the nerves, it's effects are reversible. which is not the case for DCJW. finnally, the formulations that these chemcials are in for the proffesional pest manager, are sprays and baits. the way the bait works is pretty self explanitory, but the spray is NOT dermally absorbed. it only works via oral ingestion via grooming and socialising. as they goom one another or themselves, thel ingest the chemical. for this reason it is not effective on lots of insects because they dont really groom themselves. examples of these insects may include spiders, ear wigs, slaters, moths etc insects that it would effect due to grooming may be ants, cockroaches flies etc all these points lead to a chemical of low toxicity to non target species, very effective at managing target species, and something thats pretty dam snazzy XD
