Bedbugs ETC!
My Dad said when he was growing up in the 20s and 30s, my Granny would wash the walls and floors with lye water, and boil the sheets, to be sure no bedbugs were around, evidently back then they were common, knowing how particular she was in her later years, I can only imagine what lengths she went to to clean when she was young, as for me, I always vacuum the bed, that is what all my aunts did so I do too.
