I am in the process of finishing a vase made with spalted yellow birch.
I stopped when I saw tunnels made by what could be termites, ants or
worms.
I saw no trace of any living critters. The vase looks beautiful but the
sight of these tunnels makes me wonder if I should throw the vase in the
wood stove. I wonder if we really have termites here (New Brunswick,
Canada)
with the cold weather? Or could it be tunnels made by ants?




No termites. If a network of passages, probably carpenter ants. Sweet birch
is a favorite. If here and there an open channel, worms. Channels plugged
with sawdust - grubs.
