What’s this from

[Rob711]

Almost looked like sand. This is next seasons wood. Something nesting? And real concern?

Not sure of the wood, but most likely the infamous powder post beetle. They tend to like the sapwood vs the heartwood as the drier the wood gets, the less you will see them. If it is particularly worrisome to you, spray it lightly with some of your favorite insecticide, but that probably is not necessary.

Saw post beatle dust here for the first time this year on the wood I brought in under cover. It had been sitting out 3-4yrs.
I've seen the same thing on 100yr old beams, every year for a very long time, they're very dry, and they don't seem compromised for their intended use. Am thinking for what we do for firewood, realize what they are and not to worry too much about them.

It could also be from a female sawyer/long horn beetle laying her eggs. Sometimes at night I can hear them in my wood stacks. It's actually quite loud. They won't do it during the day in fear of being heard by a predator.

I have seen it too, some pieces in my kiln have that. To be honest, I have not lost any sleep over it.

Looks to be powder-post beetle.. iv had it in the shed from time to time.. it is what it is.. but i wouldn't worry abot it at all.. only of the wood sits for a long time wiill it really become a nuisance.. youll have a lot of clean up after bringing in alot of wood..

It could also be from critters leaving the wood as it dries rather than entering it.

Don’t worry about it. I’ve never had it become a problem for us-just have to tap off some splits before you bring them in the house.

I find they don't like oak. But have them in softer wood. I keep the stacks 50ft from the house.

Thanks all!! I was never too worried. Nothing a hot fire won’t take care of!! Stack is probably 200’ from house. Just curious.

I see that all the time. I just brush the dust off the wood and pop off any bark before bringing it in the house. You have 200 feet from your house to your wood pile? I am guessing that you are in Suffolk County.
