Hello,
We have a wasp's nest under the eaves. They enter through an air-brick. I can hear loads of them in the cavity above the ceiling. They are out of the way, and there are no kids to look out for. I have been stung once - because I was painting the eaves & I got too close. My inclination is to leave them alone, but my problem is, are they doing any damage to the house? If they are not, then they can carry on. Can anyone tell me whether they are benign or malign, only as concerns the fabric of the house? Thank you.
