Yes, you are correct
I love my neurotoxins, I just can't find them anymore."DIATOMACEOUS EARTH (DE) - Diatomaceous earth is a mineral product mined from the fossilized silica shell remains of unicellular or colonized algae from the class Bacillariaphyceae, better known as diatoms.
. When DE comes contact with the insects, the sharp edges lacerate the bugs' waxy exoskeleton and then the powdery DE absorbs the body fluids causing death from dehydration.
DE sold for swimming pool filters is ineffective for insect control because it has been heated and chemically treated. It won't kill insects and it is very dangerous to breathe."
I would take DE over a neurotoxin any day. Good thing you weren't drinking it.
