APVMA Product Registration: 48148. The registration was varied in March 2025, confirming the current active constituents as zeta-cypermethrin and piperonyl butoxide.
Important stock note: Y-Tex's current Australian website presently marks PYthon as unavailable. So if TGRM has stock, I would not describe it as discontinued, but I would check replacement availability before reordering.

Tips for Best Results
- Tag as the season builds: apply as buffalo fly numbers start to rise for maximum benefit across the season.
- Always remove spent tags: pull tags at the end of their life — leaving them on exposes flies to sub-lethal doses and drives resistance.
- Rotate chemical groups: Python is a synthetic pyrethroid (SP) — rotate with a different chemical group between seasons to preserve efficacy.
- Rainfast & dipfast: tags keep working through rain and dipping.
