I have some thin slices of white birch: 1/8-1/4” thick and 4” diameter. They have these really small wood boring insects in them that I’m not to fond of. I put them in my oven for 170 for probably 1.5 hours, then put them in plastic bags just before I went on vacation for a week (just in case). I’m back from vacation and it turns out the bugs lived and the woods is still fairly moist. I can put them back in the oven, but am worried that the white birch bark browning.
In the end of this project, I will be polyurethaning over the entirety of each disk. Can I just use that to “seal” in these bugs? And will they eventually die from not being able to get out?
If not, any other suggestions?

As an alternative to “cooking” wood to kill bugs (afraid it would change the character/color), I placed it in a ziplock bag and tossed it into the deep freeze for a month. Worked on my bugs 8^)

I’d be suspicious of using poly to entomb them, chances are you’ll just make them angry.

Tried that. Didn’t work.

Run it through the microwave for 2 minutes the water in their bodies will boil.
