I mean, we had this stuff for pets for a long time. The basic idea is that yes, it's a lipid-soluble neurotoxin. Because it is fat-soluble, it spreads throughout various tissues and lingers for a good while, which is these pet formulations last for weeks or months.

And yes, it is technically a mammal neurotoxin too, although our bodies are better at compartmentalizing and managing the risk. Similarly, you don't drop dead if exposed to caffeine or nicotine, even though they are insect neurotoxins produced by plants to kill bugs.

But it cracks me up that we are flipping out about herbicides such as glyphosate or 2,5-D - both of which are plant growth regulators that have no real mechanism to cause obvious harm in animals - but we're a lot more flippant with actual animal neurotoxins such as permethrin.

A lot of the worry about glyphosate is about its effect on microbes in the human gut.
