Reply To: How do I make sure reclaimed wood has no bugs in it before I bring into my shop?

This has been sitting here unanswered, but it is probably worth an answer for anybody recycling wood.

The easiest method for killing hitchhikers is heat. The USDA says that a temperature of 56°C (133°F) for 30 minutes will kill most beetles and borers. Up it to 60°C (140°F) for an hour will sanitize the wood.

Considering that a tin shed can get considerably hotter, it shouldn’t be too difficult to rig a method to do that in most climates in the summer.

I built some cat trees out of driftwood a while back for a charity (it’s amazing what people will pay for cat related things at charity auctions) and used a steam chest at another guy’s shop normally used for bending wood. We Steamed for two hours and let it cool in the chest.
Some woods like Apple and pear will turn a nice rosewood color if they are steamed.

Before I fount the steam chest, I was considering pouring boiling water down the borer holes, but that was a small batch.

Or you could send the wood to a drying kiln. Fees are pretty modest if you deliver the wood and pick it up. If you tell them it is to kill insects and they don’t actually have to dry the wood, you might get it cheaper. They usually work well above 60°C.
