Owl inspectors (legal advicce)

[Reiwa]

Hi, I have a kind of technical legal question I'd some help with.

Every night around 3 AM about 500 people knock on my door and demand to come inside and look around. I didn't invite them and have not been given any notice of their visit, I really have no idea who they are.

They say they're owl inspectors and it's their right to come in and check things out. I have no means of verifying this or their identities and I suspect perhaps a half dozen might be owl inspector-assistants and not real owl inspectors at all.

Please help I'm getting very concerned for the safety of my owls.
