With my dad a contractor, and a brick mason by trade, I was always moving brick and block stacks. He might have a cube of bricks sitting for years, and then say, "I need 200 brick from this cube", and away I go. They love extremely dark places, and the holes in brick and the cells in blocks are perfect for them. I've been dodging those little witches all my life. I've never seen one in a house, either. Garages, yes - in a brick stack.
