“...and incineration of their home and children.”
When it comes to wasps, I prefer a Scorched Earth Policy, too! ;)
We have an old country home with lots of eves and overhangs and we are constantly battling wasps and bats. We’ve got the bats OUT of the attic, but they still roost in the ridge line caps of the metal roof, no matter what we do and no matter HOW MANY bat houses we’ve built and placed around the farm. Frustrating!
They say that if you paint the eves or porch ceiling blue it discourages the wasps from nesting there. Not sure how that fits in with your color scheme. I suppose it depends on how badly you want to get rid of the wasps.
