What does one usually do when finding worm holes in wood?

A. Do I ignore the holes and just sand and finish (Danish Oil) as normal?

B. Or do I need to do something first in case they are still alive and eating into the wood, which will affect the final product?


The wood is a slab of Guanacaste

Is the wood air dried or kiln dried? I have a slab that looks very similar to that, which was used in some outdoor furniture and it has quite a few bug hole like you pictured, but they all appear to be old and vacant. However the holes only appear in the lighter colored sapwood, not in the darker heartwood.

Those are not worm holes. It could be problematic depending on whether the bus are still there or not. Since we are getting into Fall/Winter months, the bugs become less active. So, you can create a suitable environment for bugs; lets say 85 degrees to see if they are alive or dead. bring the project inside, put it on a bunch of newspaper and look for sawdust every week or so. If you don’t see any in a month, you are probably good to go with your finishing process. I usually pour some CA glue in those holes and mix glue and sawdust and force them into the holes. You can use darker sawdust to create a contrast or neutral colors to make it match..

@Richard: I don’t know how the wood was dried, but you are correct, the bugs have only bored into the sapwood and not the brown wood.
@mrjinx007: Thank you. I took a needle and poked every hole to try and clear them out. It worked for some, but not for all. They really made some deep holes. I don’t think however that any are alive in there. (Hopefully).

Jonathan, I wouldn’t be so sure. I recommend taking mrjinx’s advice and be sure. Otherwise you can go ahead and treat the boards with insecticide or a heating treatment without testing first.

Regarding what to do once you’re sure there are no bugs, it depends on what kind of look you want. If you want a rustic look you could just leave them open. Many people like that look and even buy ambrosia wood, with the holes, on purpose. If you want a bit more of a refined look, you could fill them with putty or glue of an appropriate color.

Is there a recommended insecticide to use? One that will dry quickly, not ruin / discolor the wood etc.?
Thank you for the putty suggestion.

Is mineral spirits enough or does it need to be lacquer thinner?

The best method I’ve heard of is putting it inside of a plastic bag with a bug bomb. I can’t attest to this method but I’ve heard of it being done successfully.

Thank you all.
I placed the wood on two saw horses covered everything with painters plastic and bug bombed.

Have your say...
