Topic tags/keywords: powder post beetles

I searched all the previous threads on this topic and didn’t get a definative answer so I’m posting this. I recently built a walnut folding chair, finished with several sprayed coats of Spar Urethane, and sold it for a good bit of $. The owners report tiny holes with bits of sawdust have appeared. I want to do the right thing but they aren’t looking for a refund if it can be fixed (bugs killed) or I’ll make them another but I still need to know what to do to kill these critters if possible. Calls to several exterminators have not produced any answers as they don’t know what to do either. HELP! Edit: This was supposed to be kiln dried lumber so I don’t know where these came from and I haven’t seen any other damage in my shop?

Put it in a microwave for 5min on defrost.

or

Fumigate it for a few days and then test it/give it back.

Rance…you must have one huge miscowave if you can fit a chair in it.

Powder post beatles. They are a pain. I threw away a cabinet once that had them but I understand that there are options to get rid of them. i am not sure what they are but i have seen others post about their solutions.
Good Luck!

I bet if you put the chair in a big black trash bag and left it out in that Oklahoma sun it would be almost like an oven or kiln inside.

i don’t know if it might work andy
but as it folds up

if you can put it in a top opening freezer
and let them freeze for a while
that may do it

if not wrapped in some plastic sheeting
with some exterminator powder
or fumes might work
(like tenting a house)

good luck

I would just put the chair in a large plastic bag or sheet of plastic, shoot some insecticide in it and close it up for 48 hours.

I like the black bag in the sun idea.

Find a place that paints cars, put in in the oven they use to
cure the paint. Any antique dealer who handles furniture
should be able to make recommendations to your client.

Thanks for all the quick replys. Can I fumigate it effectively by bagging it and setting off one of those Raid bombs in the bag; then leave it bagged for a period of time? This is my problem NOT the new owner’s so I need to deal with it. Thanks again my friends.

I would just go to your local garden center and get some insecticide for powderpost beatles and use that in the bag.

I feel your pain brother , it must be very frustrating to have executed a piece of work and have this happen. I beg you not to worry yourself sick over it keep in touch with the people and some of these ideas will work. I would contact a local university or wood college and ask their opinion before starting on any of the frezing heating ideas they may make the damage worse or joints come loose etc take it easy and keep cool,after all it’s not exactly your fault.Alistair

About 8 years ago I was helping the finishing department for a small aerospace plant on a project for a couple of weeks. Three of us were in the finishing department one Saturday morning all decked out in our clean suits doing some serious work for one of their finishers who just happened to be a woodworker.

We had their drying oven set at 200 degrees for one hour. Inside the oven on the drying racks were 2 dozen 2×8’s x 8 feet long full of the famous wood eating bug…at the end of the hour those wood eating bugs were no longer living…course we had some cleaning to do to purge the oven of dust.

So, heat does kill them.

Here’s my five cent’s worth, Andy. 1) KNOW SOMEONE WITH A WALK-IN FREEZER? Leave the chair in it for a few days. 2) disassemble the chair; put all parts in a big plastic bag and set off a bug balm in it and leave it alone for a day or 2 or 3 . . . until you hear nothing with your stethoscope. Hope for the best!
