Depending on the size of the pieces you intend to use in the cutting
board, you could microwave them. That will kill,but not remove the
varmits. The amount of time in the microwave would also depend on the
wood's size and density. Try some pieces at differing lengths of times.
It's not the heat that kills, so don't over do it. Just fairly warm to
the touch should be sufficient.

As an aside, I like to warm completed wood objects in either the micro
or the conventional oven just before applying oils of any kind. I think
it allows for greater penetration. I tried it only once AFTER
application of Watco. The wife was NOT happy. Took several heat cycles
and some vinegar baths to deodorize the conventional oven.

I pulled some logs off my log pile to turn into lumber to make a
cutting board, but naturally there are bugs in the wood... So, since
this project will be a cutting board and in contact with food, what is
the best way to kill the bugs and not kill me from cross contamination
:-) ?

In the past I've put smaller pieces of wood in a microwave to zap the
little suckers who might be burrowing away inside. The wood I have
prepared for the cutting board won't fit in a microwave...

Thanks for any suggestions.
