What's in the wood stack

[Berner]

Stacked up a grapple load two years ago. Tarped it and left it to season. The other day I took the tarp off and found a bunch of sawdust. It seems to be present in a few places, not every piece. Any ideas what it is? Seems to like my ash. I'm 13 miles north of Boston.

Maybe an ash borer?

Those close up shots don't look like ash. Ash borer will leave a D shaped hole in the bark.

Needs to see a body cause there are any number of critters that make dust like you are seeing. Don't worry, dey won't eat much whatever dey are!

powder post beetles

Shoot straight is correct. Powder post beetles. We never worry about them except to make sure we whack off all that fine sawdust before taking the wood into the house.

That's crazy they know a letter of our alphabet. Should be an A or a B though.

My wood ID skills need some work.

Are these beetles hazardous to my house? I keep a week or two worth of wood on the front 3 season porch. Anyone have any problems with these guys attacking their house

Your house is probably safe if it is really in ash as mentioned above. Two beetles make flight holes like in the pictures. One is the Old House Borer which prefers softwoods. This rascal would love your house. However, this one was in a hardwood which would make it a Forest Longhorn Beetle. No problem here because he only attacks hardwoods, and won't infest seasoned woods like your furniture.

No. They won't attack your house.

Burn on! Thanks, it looks like I'm free to stacks on the porch.
