On my grandmother’s farm there was a very big box elder tree that would be red from the solid covering of BE bugs. I was badly scarred as a child and hoped that when my neighbor cut down his BE tree they would go away. He didn’t remove the ~3′ diameter stump and there is a cluster of “treelings” growing up around it. I’m sure some are hiding in cracks in my stucco and the soil near the house because they tend to be on the south/southwest side of the house.
