I have some fresh milled wormy maple boards stacked with some fresh milled wallnut boards. The boards are air drying and pretty wet right now. I dug in a few spots but can’t find any worms but there probably there. I am thinking I will dry the maple for awhile then try to find someone who can kiln dry them the rest of the way. The question I have is will the worms migrate to the wallnut or are they specific to maple?
Any thoughts on this?
Tom

No. The “worms” are ambrosia beetles. There are every where in the environment. The will infest only green wood that has been freshly felled or a tree that has died. Once the wood has been sawn, the beetles leave in just a few days to a week as the boards begin to dry. They will leave the drying walnut alone. They are not fond of walnut anyway, and only get in walnut sapwood while the wood is green and in log form.

Woodcut1,

I am not sure what infestation you are seeing. I share your concern about infested wood, having purchased red oak and walnut about 7 years ago. It was abused wood that set in the weather before I came along. It has since been in the dry and some signs of active infestation are evident in the stored lumber. I also encounter tail-tale signs when using this wood on a project, probably from a former infestation. At any rate, I found this University of Kentucky article that discusses Powder Post Beetles. An easy and informative read:

Powderpost beetles infest dry wood, not green, so if you have fresh sawn lumber, any beetle activity that you see will be ambrosia beetles. If you spray the boards with TIMBOR, the borate will prevent any PPB infestation.

I am pretty sure the marking on the wood are ambrosia. I think this log has Benin lying by the mill for a few months so I hope no powder Beatles are the also. Other than holes and markings I haven’t seen any dust or any signs of activity.

Have your say...
