Once had a home with a shower that leaked water into the wall.
Carpenter ants walked the power line coming into the home, down the pole and
into the bathroom where the fuse box was located. There was really no visible damage, but once I
removed the panel of the shower wall it was ant city, They were running around by the multi hundreds if not thousands.They burrowed into the wood of the long wall of the shower. I had to place a lot of the 2x4s in the wall, to repair the damage and have a good surface to renew the shower.

Fun times, 1984, just closed on the house with a 13-3/4% mortgage, 1 month later I got laid off.
Luckily we had been married and saving for about 3 years, we had enough to get us through a bit of a hard time.
The 13-3/4% was with a 3 year balloon, a 30 year was 16-3/4%.
