Those worm holes are filled/lined with worm poop.

Lathe ‘em off and fill the rest.

Or paint with enamel to seal & provide color color contrast.

Or fill with color stone & epoxy.

There is no one answer. Depends on the piece, the look you want, size, location, etc… As Mark said, if they are filled, it is worm poop (frass). You can leave it in and seal it, or dig it out and leave it hollow, or fill it with something else. On pieces with a lot of them, I usually will just seal them up. Soaking with thinned polyurethane works well, and I’m sure other methods like with CA glue would as well. For others, I’ll dig ‘em out and leave hollow on more rustic pieces, and on others will fill with a tinted epoxy or epoxy mixed with various other items like metal shavings, crushed stone, etc…

It’s your piece – do what you think looks best. Nobody will agree what that ‘best’ is, so it’s your call.


PS: Leaving the frass sealed in place does provide a very lively talking point once people find out what it is!

MrUnix covered it well.

If I can’t turn them off without causing a problem I often collect some fine sawdust using a rotary sander with a collection bag on it, or a belt sander. It can be matching or contrasting. I then pack it in the holes then quickly soak it with thin CA blue immediately followed with a medium glue. The thin glue acts as a wicking agent for the thicker glue. If the holes are not very big I just use medium CA glue which cures slow enough for it to soak in if it is a small hole or crack. I have done this so often I have made a collection of fine sawdust in various wood types and stored in small jars ready for action.

Sand a pic. of it to get some dust and mix with glue, then fill the holes , put some glue in the holes first and then fill. you will have a hard time seeing them after they dry .just sand a little after they dry.
