Possible wasp nest and/or bird nest inside the outer wall
Yesterday afternoon, I noticed a strange noise coming from behind the outer wall (to the left-hand side of the window) in my daughter's bedroom - sounds like a lot of ducks! It is a constant noise even really late at night - I asked my daughter about the noise and she said that she thought it was the neighbour's ducks, however, my neighbour has not got ducks this year. This morning the noise is still going on and I went to look up at the roof area from outside. No sign of any birds flying in anywhere, but I did notice above the outside window - in the corner near the roof - a couple of wasps flying in and out of the same area. I'm now wondering if there is actually a wasp nest inside the wall area. Could the noises that I have been hearing, actually be the nest creaking with the wasps in it? I have read that they can chew through plasterboard walls, so am a bit worried that they are actually chewing at the back of the plasterboard. Any ideas on this, please? Thank you.
