Bees in outside wall

[Kaz10]

Hi guys,

Thank you all for your replies. I have been on Bee watch (or should I say my cat has!)and will try and upload a very fuzzy picture of one of the bees.

In the last 10 minutes there has been half a dozen or so going in and out. They are not swarming the area they just appear and fly off and then return.

I am in Stirling and if anyone can help identifying them (sorry about the quality) and whether or not I should get something done about them.

Looks like a white assed bumble to me. But then, that blue thing looks like something out of Z cars.

They look like bumble bees. The colony will vanish once the next season's queens have been mated.
