Borer Hole
A borer hole in lumber refers to a small, round hole that is made by a wood-boring insect, such as a beetle or a moth, as it tunnels through the wood. Borer holes can be found in both softwood and hardwood lumber and can vary in size depending on the size of the insect that created them.
The presence of borer holes in lumber can be a cause for concern, as they may indicate the presence of an active infestation of wood-boring insects. These insects can cause significant damage to lumber, weakening its structural integrity and potentially causing it to fail.
