if it affects flesh that way wouldn't it have clear effects on the internal organs? or are the biology of insects so much different vs mammals this kind of tec

  Lots of poisons (and herbicides, and medicines too) work by targeting a single chemical pathway. E.g. binding to a specific receptor or doing something to a specific protein. I think insects and mammals do have pretty different biology, but even if they didn't it would only take one chemical pathway that insects used and mammals didn't that you could exploit.

  > if it affects flesh that way I assume you meant to write fleas? But in case you meant flesh: it does not affect muscles directly, it affects neuro transmission. (which of course paralyses the muscles) > wouldn't it have clear effects on the internal organs Excellent question. And yeah it seems invertebrates have different molecular mechanism enough that these drugs affect them and not us vertebrates. This does not appear to be 100% though. There are some, admittedly very rare, reports of neurological effects in pets. There is this[1] case for example of a Kooikerhondje exhibiting neurological symptoms. Luckily it seems at least in that case the symptoms cleared up on their own after about 10-11 hours. > this kind of technology perplexes me oh yeah. As far as I'm concerned "this is witchcraft" is actually a more satisfying answer than the reality. Caution: There is a quite distressing video embedded in the article showing the dog exhibiting symptoms. You might want to skip this one. 1: https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-019-2016-4 https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-...
