We didn't see them untill about 3 weeks ago then kept finding sleepy ones on the landing and upstairs window sill. DH went into the loft and soon came out, there was a huge nest. When we went outside they were all over the wall near to where they were going into the loft.
Luckily our insurance covered it and the chap came out and sprayed from the outside with an extending tube, they no longer extract he said "Health and Safety".
We have to watch for anymore and report again,saw a lot in the garden yesterday so now on wasp watch.
Recalled for a further appointment after a routine mammogram
