surprised they didn't chew their way out... i have rough-cut lumber siding varying from one-two inches thick on my house, i find piles of sawdust on the ground all summer long
I had a problem with them once. They made a nest in the exterior door facing. I waited until it went in and plugged the hole.
It was very angrily buzzing but eventually died.
Fifty caliber is about right for the hole size at my house too
