this is my first time going from log to bowl, so please forgive me if I've made any really dumb mistakes.
I felled a birch and a beech tree (I'm in New England) and cut them into ~4-foot long sections to dry for a year or two before I put them on the lathe.
I made a double boiler and melted down some wax in order to seal the cut edges, and I think that part went OK.
However, a month after being sealed and left in my cool, dry barn for curing, I checked in and noticed many little cones of sawdust under the logs (see photo).
I don't mind wormholes or other small perforations in my finished products, but I certainly don't want to feed or shelter whatever pest this is if I don't have to.
I'd like to keep the wood food-safe, if possible, as I mostly make kitchen bowls and muddlers.
My question is: what is the best way to eliminate this pest?
Thanks for any help you can provide!
