Thanks goosey and Sebastian.
It does look more like the german wasp doesn't it with a definate dot on its head. I've zoomed in on the photo but can still only make out one dot and not three which makes me a bit unsure. Do they sometimes only have one dot? I shall also have a look on the internet to see if I can find out any more.
Well, we went up again today (I forgot my camera!!!!
....don't know how that happened its usually glued to my hand!
) and it was back and just making the core bit that joins onto the ceiling. So once again we removed it and I had a brainwave (I hope) of smearing vapour rub where it had been and on the crack of the door where I think it's coming in. It flew back in almost immediately but went straight back out, it did this intermittently for about 15 minutes and then didn't come back. So, we now have our fingers crossed that it will find somewhere else to make its home.
Apparently it's a solitary queen wasp that makes her nest in the spring, makes 20 to 30 cells, lays her eggs and before you know it you have a colony of 3000 wasps!!
