The local animals moved into the building over the well. They aren't good housekeepers, but the plumber's idea of how to deal with an old panel is interesting.
I had to work in a "room" like this before. The walls were alive with thousands of Cave Crickets. Every time I moved, so did they. They would jump all around me and on to me. It was terrible, but I had to get the pump working again because there were several homes without water.
