Poking around I found something on the internet that said that Porcupines crave salt and certain building material treatments that seem like salt to them.
Yep. Apparently the glue that's used in plywood is one of them.
I maintain communications equipment, and one of my clients has a plywood building on a mountaintop that porcupines (and squirrels) love. Porcupines came in underneath and chewed several holes in the floor, fortunately none of them under the equipment. We ended up siding the building with metal roofing, and made sure the bottom end was several inches underground. No problems since (knock knock).
