Squirrel urine staining
the aluminum siding on a house.
Squirrels have been living in
the soffet above this siding. Snow and ice water dammed in the gutter
and got into the soffet and saturated the insulation (nesting) which
was contaminated with urine. This mix of water and urine then seeped
down the side of the house destroying the siding and the inside wall
and floor.
