When I first started harvesting green wood for my workshop, I was worried about bringing wood-boring insects into my workshop. It would be like letting loose 1,000 raccoons into a Golden Corral restaurant.
So I got some advice from fellow woodworkers. All of the advice involved pesticides. And some of it sounded reckless. (Put the wood in a garbage bag with an aerosol bug bomb. Be sure to tie up the bag really quick!)
Years ago, I found this short article by Michael F. Potter, an extension entomologist at the University of Kentucky College of Agriculture, and it was exactly what I wanted. Potter recommends eliminating insects from the wood using your fridge or your oven.
I’ve been using his freezing method for several years, and it has worked brilliantly.
In short: Put the wood in your freezer and set it for -4° F. Let the wood stay there for seven days. Remove it. Done.
Potter recommends using a plastic bag to protect the wood, but he’s mostly concerned about finished household items. I haven’t found it necessary when freezing raw wood.
The article also discusses how to kill bugs with your oven and gentle heat. I haven’t tried this method yet. I want to experiment first with some test pieces that are green because the method might rapidly dry out the stock and check the ends. (Potter does recommend adding a pan of water to the oven to keep the humidity high. I am interested in this technique; I just haven’t had time to give it a go.)
Another bonus with the freezing method: If you keep the green wood in the freezer it won’t dry out and will stay green as long as it’s frozen.
All this is just another excuse to add a beer fridge insect deinfestation device to your workshop.
