Started to plane the walnut board and revealed these …is it woodworm? Hoe can you tell if it’s still active? Should I treat it?
Plan was to use the board as coffee table, so have concerns treating with nasty chemicals will make it unusable in a living room or kitchen environment.
Definitely woodworm, I encountered some in my pieces.
One particularly bad piece I quarantined and left outside, checking up on it had a load of little beetles running about…
All other pieces seemed fine despite little burrows but I guess it’d be hard to tell immediately but I don’t think that they’re active… I would say microwave to be safe but that board would be a little large… Walk in freezer would be another method to be sure to kill them.
Else mark the ALL spots and keep an eye for any further developments - probably bagging the piece somehow so they can’t roam about.
Not had to treat anything before but can’t imagine this would affect it’s use as a coffee table given there will be a solid layer of finish over the top.
