I just got what I thought was another good deal on lumber, about 100 bf of cherry and some walnut(I think) flitches. All for $75. But, as I was looking at the flitch pieces, I noticed some insect holes. I think powder post beetles. This is the walnut with the holes:
I didn’t notice anything on the cherry, except for one board that looks damaged, but no holes. Do you think this is an active infection? Or damage from some time ago? I know these boards are pretty old. Thanks! |

I would treat it like it’s active and not store it with other wood or in your house. There is at least one thread around on how to deal with buggy wood. One way is by heating the wood . -- W James Brokenbourgh Custom furniture maker http://artisticwoodstudio.com/ |

If you still have any hot weather, wrap them in black plastic and set them in the sun with a thermometer. I think if you can get them to 140 for a couple hours it’ll be okay. Kiln drying usually doesn’t get that high in temp. -- Failure does not stop me, it makes me try harder..... because I'm crazy. |

As suggested, I would treat as an active infestation. I have had 100 year old myrtle wood in storage for several years, untreated, similar in appearance and there is evidence of activity. I will also take action on these suggestions. |

Heat kills. Wrapping it should work. -- Mother Nature created it, I just assemble it. - It's not ability that we often lack, but the patience to use our ability |

Im in PA, no hot weather left here. And it will probably be a month or two before any real deep freezes. After reading some more, I think I’ll try Timbor or borax and wipe everything down. I just hope the buggers haven’t gotten into the cherry that I already put inside my basement. The walnut is what has visible evidence, I think I’ll keep that outside for a while. And I’ll keep a close eye on the cherry for evidence of new holes and dust. Thanks everyone! |

RussellAP, I am a kiln operator and this statement is incorrect: “Kiln drying usually doesn’t get that high in temp.” -- Scott, North Carolina, www.quartersawnoak.com |

Those holes were made by ambrosia beetles. Notice the black tint to all the holes. This tree was dead before it was sawn into boards. The ambrosia beetles attacked the tree as it was dying and under stress or when it was already dead. Unlike the dreaded powderpost beetle, ambrosia beetles only live in wood with a high moisture content. When the wood dries, they are gone. They also commonly attack soft maples, resulting in a black lined hole with a blue-green stain that comes from the hole in streaks. The black lining to the hole and the blue-green stain are caused by a fungus that rides in on the body of the ambrosia beetle. The blue-green stain can look like flames. Ambrosia maple is highly desired. The ambrosia beetle holes can give the wood some unique character. Scott, as always, gives great advice on sterilizing wood. If you only have these ambrosia beetle holes, you are OK if the wood is dried. However, powderpost beetles will infest walnut sapwood. You can tell because they will be little pile of sawdust coming out of the holes. If you see this, you must remove all the sapwood or sterilize the boards. They do not infest walnut heartwood, but they are a scourge in many other species, especially the ring porous species like the oaks, hickory, pecan, ash (Oh, they love ash), elm, persimmon, etc. -- Wood-Mizer LT15 |
