I’ve got all my wood into the barn, twelve rows 8’ long 8’ high. I moved them from the sun word side of my back yard stacked on pallets. It took me awhile. During the move I’ve noticed this saw dust on the logs every where the wood is mostly cherry, oak and hickory but it’s a mix of every hard wood for an upper Midwestern woods. There’s little round holes in the splits, any idea what bug is infesting my wood pile? pic's to come.
