Hi
I have hardwood sashes fitted. On the lower edge of the upper sash there is a small hole at either end, about 1/4 inch diameter. Not sure what this is for, drain holes prehaps?
Today I noticed in the space of an hour about 6 wasps enter one of the holes (might have been the same wasp 6 times, couldn't watch closely enough but didn't see any leave).
Are they likely to be causing damage? ( I have sprayed some "raid" up there in the meantime)
