Ladder traps in Scotland

[air gun ant 1,666]

I’m thinking of building a ladder to put on the shoot up here, saw a thing on the internet about attatching a permit number? What permit do I need? I thought it would be covered under the general licence but I no the laws are different in Scotland for snares so thought I’d ask you knowledgable lot

Phone the police wildlife officer tell him you need a number to put on crow traps and he will give you one and ask him to email you the general license and if he can include control of blackback  gulls in it for the protection of game birds,wf
