Trap it with 4 metal gates and a large bear trap and light it up with tranqs or get into a confined space with ledges and light it up then or of your feeling cheeky then shoot it on a quetz.

This will make the torpor climb throughout the entire tame and if it's safe you can leave it until it needs feeding.
