Anybody know what sort of critter left this behind?
Found it when splitting a piece of red oak. Couldn't find anything alive. No holes to the outside found, so must have crawled down from another section.
It looks and feels like spray foam insulation.
Can I add this to the stacks, or is it going to hatch a million wood devouring critters?
