Looks like a wasp to me, it's not a bee. You may have to get them removed....

It is common wasp. They are very much a friend of gardeners, but not when nesting above the door. At the moment they are unlikely to bother you unless you pester them but, when the colder weather comes they get dopy and you are more likely to get stung. If they are going under guttering and into the roof space you may need to get profesional help.

Thank you Louisa and Bulba for your help and advice. I shall contact the 'exterminator'!

We had a wasps' nest in the cavity wall insulation just above our bathroom window, and they got into the bathroom via the airing cupboard. A bit scary! The council would not touch it because it was higher than 8 feet above ground (!) so we put up with it, but you will find a private contractor to do it (unless, of course, your council pays for better insurance than ours!) Fortunately, once a wasps' nest is abandoned, it is not revisited.

There are hand-held sprays that are very good at getting rid of wasps - I've used them often - never fails for me.

Wait 'till they've quietened down in the evening, creep up quietly, give it a good spray and run in the house as if the devil's after you.

I've never been stung yet doing this.

Melchisedec I have contacted a local exterminator and he will come on Monday for £40! I'm very pleased to hear that once they've gone they won't return.

Hank I appreciate your advice and if I was a bit braver I would take it but I'm one of those people who are allergic to bites/stings, the last time I got bitten (abroad) I had to be given a penicillin injection because my arm swelled up to balloon size, so I think I'd rather fork out the forty quid!

£40 seems quite reasonable, Jk, and well worth paying out to know that the job is properly done with no risk to yourself.
Hank, I normally deal with wasp nests myself, but above the door like this I would have second thoughts about it.

That sounds like an excellent solution, Jaykaty, and I agree with Bulbaholic that it seems very reasonable.

Sounds reasonable to me too, especially as you're allergic to stings!
