TSP mixed with Dylox turns the active ingredient into DDVP aka Vapona. That is an organophosphate pesticide with an LD 50 of less than 100 MG/KG and very easily absorbed through skin. It is also extremely volatile. I would rather take my chances with a Merit application drenched in with a soil surfactant.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.

Sell not virtue to purchase wealth, nor Liberty to purchase power.
