Whats eating my wood!!!

Got a piece of pecan sitting in the garage and today I was looking at it and there's holes all in it and piles of dust around it and I can hear something in there chewing! How can I get them out? I poured seven dust in them but their just chewing away.

Burn it, get rid of it. Those are exit holes to larvae
They'll keep on chewing away. Or you can spray it with a borate solution to kill the eggs and larvae. Happened to me recently working on a cherry slab with live edge with the bark on it. Had to peel the bark off because they were in the bark. After cleaning it up they left worm holes which turned out pretty cool. You could probably mix up borax and water to make your own solution to get rid of them.
Also you could build a smokey fire and suspend it above the fire and smoke them out. Did that on a root stump before.

When it's rustic......it's rustic

I recently cut up a honey locust that fell in a ladies yard. It was full of ants near the base. I brought it all home but only a couple small pieces from near the base and the next day those pieces had the same holes just a bit smaller. I took those pieces out of the garage so they didnt eat the good wood and havnt seen any since. It amazes me how much wood a carpenter ant can bore through in just one night.

RRBrown, knottscott and many others were banned, they didn't just leave. They were banned for standing up to the new owners that are destroying this site. Come join us all at woodworking chat, the best new woodworking site on the net!!

Flood/saturate the holes with electronics contact cleaner (non-residue type) or ether if you have any. It will usually chase them out to the surface and kill them as well. Staining should be minimal.

Just a thought. I've done it several times and have had no problems or noticeable staining from the spray.

First, get it away from any other wood or the wood used to build your house.

Second, it will be almost impossible to de-bug it as long as it has not been milled into boards. You can't heat it when it is in log form. The heat just won't penetrate. Chemical treatment will probably not be effective either.

One of the rules of drying and preparing your own lumber is to end seal it within hours of cutting into logs and then to mill into lumber within a few days.

You might try taking it to a saw mill and have then cut it into planks. They have them kiln dry it. That will kill the critters.

If you cant do what Howard says - BURN IT!
Wouldnt be the first time a woodworkers worms got into eating his real furniture, or his house. Just follow the sawdust trail.

My mom had some boring beetles eat up her wood floors, I picked up some pesticides (after showing the owner pics of the damage) from an alternative pesticide store in Jax, FL and it did the trick.. You might want to find a DIY pesticide store and bring in a sample of the wood/bug to see what they say.

I just bought some Catalpa slabs, that were pre-dried.
I bought it because of the bore holes and the interesting patterning because of it. When I got it home, I noticed black ants gravitated to it,so the holes must have been ant chew. Next thing I found was small piles of sawdust only a week later. I pulled em out to see and ants were everywhere.
I used an ant spray and there must be 200 dead ants laying there now. No clue why they gravitated to dried lumber.

I would defer to others here for their methods. This stuff is new to me.

Build your own sawmilled yellow pine into a house addition. Save some money.
Lie awake at night hearing them chewing in the walls, floors, ceilings. Think about selling the house.
Pay $3000(1985 dollars..cough..) to have the house completely covered with plastic tarps and shot full of DROP-DEAD poison gas.
Sell silent house. Live happily ever-after.

The "dust" you're seeing is called FRASS. More often than not the bugs are powder post beetles. Super heat (as in the attic) or fumigate. Last resort is to trash the wood.

update

debarked areas and applied ortho home defense max (squirt in holes cheapest stuff I could find at hardware store)
3 days later FRASS only from half the holes

Repeat 3 times,

only one hole still has frass, will keep an eye on and repeat

Does the lack of frass mean they are gone for good?

No, but it is possible that you could spray the entire surface and wait maybe a year, after which you'd be rid of them, because they must emerge to mate as adults outside the wood, and chewing their way out, they'd croak.

Who knows what the residue of the pesticide does to the woodworker, though?
