Topic tags/keywords: live edge tim bor powder post beetles

I purchased my first few live edge slabs a few months ago and have the dreaded powder post beetle..So i have this real cool piece of fig apr. 18” x 5’ 6”x 2” with a crotch . Have tried 2 dosings of Tim-Bor and 1 wrapped in black plastic baked in the sun..But not working. Have read about need for a kiln,but no source in my area ..So am wondering if there is any other option before i trash it..possibly some sort of small funky hot box ? Thanks..Greg

Do you know anyone with a big chest type freezer? Meat Locker? Ice Cream storage or distributor? Leave it wrapped up and stick it in a freezer for a day or two.

I personally use Bora Care brand treatment mostly as a preventative.One of our local pest controllers told me that he uses Bora Care exclusively on powder post beetles I’m not sure but I think freezing them won’t do anything except make them dormant . Kiln drying will fix’em for sure.I been told that all you really need to do is cook your wood at 135 degrees for 72 hours to kill everything, eggs and beetles. I bought some red oak once that had a minor infestation in the sapwood once and put ‘em in the kiln and fixed them. But I didn’t run the kiln over 125 .

Thank you for the responses..michael..there is a 31 flavors down the street i frequant..I’ll chat em up..But hoping there is a better option..
Scotsman..That may be my best option ..I do smoke like a madman..Does the kerosene eventually evaporate ?

Swoper..The piles are down 30 % , but hard to say..The lumber was cut probably 6 months prior to me purchasing if that tells u anything? I here it is more effective just after milling but i dont know much except what i’ve read.
pv..Thanks gonna hold off on more chemicals for know.

What about drowning the critters? Or a 4’x4’x 8” ply box with a heater ? or is that a fire hazard ?

Just a framer ..Greg

Harry; You could give Jeff Tervol a call. 517-287-5745. He is south of you down US127 in North Adams, MI. He has a saw mill and also does custom Kiln drying. He did a few hundred feet for me this last winter. He also has a good selection of nice native dry lumber.

Oluf thanks for the heads up but i have the beetles in the post that are the barn structure, I am going to try the tim-bor since I have really have no other low cost option. I do have a large oak on the property I was thinking of getting cut up I will give him a call if I do that

So, stupid question time. How can you tell if the lumber has these beetles. I have heard about looking for little dust pile but are there any other indicators?

Chris, yes little dust (frass) piles and holes in the wood. Here are a couple links for everyone to ID wood eating bugs.

I was looking for the article about it. It was either on the FWW site or Woodweb. The person said you can Bake ‘em or Freeze em, either method works. Gradual decline in temperature, like the change of seasons, allows the insects time to adapt to the change by changing body chemistry. Abrupt change in the temperature, like taking it from 70 to zero or below in a few hours by putting it in a freezer, kills the bugs.

Heat works but you need 130 degrees internal temp. for 4+ hours.

Here's something

Good time to make a steam box for steam bending? Surely that gets hot enough. And then you’d have it afterwards.

I have made a small hot box out of styrofoam insulation taped together to create a heating chamber. As the heatsource I used 3 halogen lights. Temp got up to 160 degrees in about 3 hours. I left it cook in there at that approx temp for 6 hours. I check my offcuts and sure enough the critters are dead. Pretty simple just be sure that you keep an eye on everything so that you don’t melt the styrofoam or get it too hot.

I have had them also. Generally, they bore into the tree while it is still standing – the holes and dust are made on there way out of the board. Usually the timbor or borate treatments don’t kill the eggs that are still inside, though heat and or freezing can. One of the benefits of kiln dried is that if they did it right, they have already killed the larvae in the lumber – and one of the risks of air dried is the surprise you get when you see the dust.

Don’t try to use a space heater…take John’s advice on the lights, and yes foil backed would be your best bet.
