I have some old pine barn wood that’s been laying around for about a year. I went to check it out today and noticed tiny piles of sawdust. So I’m assuming there are powder post beetles in the wood.
Question: would a Raid bug bomb kill them if I wrapped the whole thing up in an enclosure about 4×3x8? Or do I need to get some other bug treatment spray?

I think the only way to be 100% sure everything is dead is to heat treat the wood. Make your own kiln (many examples on the web and here) or rent some time in a professional kiln. I’d be forever worried that the chemical didn’t reach the bugs inside the wood.

Yeah, I just ordered some timbor… Maybe I’ll build the bench today that I was planning on building, and then just treat it when the the timbor comes in on Monday….

yep heat treat! I don’t think powder post beetles care for softwood.

The bug bomb will not penetrate the wood. Fumigation if the only way to do it chemically. Heat as mentioned is the easiest. Just putting it out under a layer of clear plastic (preferably on a dark surface) all day on a hot sunny day or two should do it.

So I decided to go the kiln route… two sheets of insulation and an old space heater gave me readings of between 150 – 180 depending on where I put the thermometer. I had it on for about 8 hours today, and now I just unplugged it and am going to let it sit overnight, assuming it will cool down gradually so they should actually be cooking for about another hour or so… I’m pretty confident a temp of 150+ should be enough to get rid of the PPBs…

@ BFamous… will you post a pic of your improvised kiln? I’m curious to see how you put it together.

Here you go. It’s super basic. Just take two 4×8 sheets of rigid foam insulation, rip them down the middle so they are 2×8. Then tape 3 of the pieces together to make a long box, then cut two 2×2 squares from the remaining 2×8 to make the ends.
I happened to have a few extra pieces of insulation laying around from the last time I did this.
The wood is just stacked and stickered, with the heater sitting next to it.

NOTE this is not for drying wood, as there is no dehumidifier to remove the moisture (you can actually see the dampness on the garage floor if you look close….

What heater did you use that let the temperature get that high? I’ve been looking but almost everything has too low a thermostat.

The type that is sold old the timer and thermostat are both defective… Haha. That space heater is probably close to 20 years old. It still heats up great, but if I don’t turn it off it will just keep running forever.
Sometimes broken stuff works the best…

When I am sterilizing wood in my kiln, I hold the temp at 150 degrees for 24 hour to assure that the internal wood temp reaches 133 degrees, the internal temp required to kill powderpost beetles.
