Like I said on an earlier post, If you've got mustelids taking your eggs or your chicks then fair game, go catch your vermin. If not and it's just because you've got a mk4 in the shed and nothing better to do then err .................. find something better to do.
You can't eat them so wait until they step out of line.
As far as I know the General Licences don't apply to vermin like weasels and stoats (and Polecats are fully protected).
