HCH and gamma-HCH were banned because they caused much more harm than
the 'pests' they were used to kill.

Why were they banned?

Clearing out sheds recently I found several packs of Gamma-HCH - which
I've used in the past to dust to stop ants entering the living-room from
the beds at the front of the house.

What would be a safe means of disposal if I really shouldn't be using
it?
