Question
what kind of bug/worm? bores holes in wood the size of a pencil lead and piles the sawdust on top of the hole? What can be done to get rid of them? Thanks for your help.
Answer
Stacey,
This is a perfect description of a powderpost beetle. The holes and sawdust are made when the beetle bores out of the wood. The larvae live inside for months or even years feeding on starch that is stored in the wood. The exact type of beetle depends on what kind of wood they emerge from, whether it is hardwood like oak or a softwood like pine. Here's an article about powderpost beetles http://www.livingwithbugs.com/powderpost_beetles.html that includes pictures and links to control information.
Post a follow up after looking over this material and we can discuss control options. Tell me what kind of wood is infested.
