As has been said, the little sods are most probably long gone, as for treatment fluids, they do work but brushing the stuff on a varnished cabinet is a bit pointless , if you are concerned then direct injection into the flight holes is best.
Personally I wouldn't bother filling the holes it's all part of the sets history.
There are plenty of other species of wood boring insects, a common one that some folks think is the traditional woodworm is the bark beetle, sometimes the galleries that they create can be seen in plywood but rarely on the face surface, the galleries are very dark, almost black, another one is the wood wasp, you can't miss the holes 'cos they're big.
Sapwood is generally what the critters like.
