Is this woodworm?

[RR123]

I found this one a couple of joists in my living room. If it is woodworm, would a few thorough coatings of something like this be sufficient to kill them off?

Any light sawdust around the area? Underneath etc? Any other areas like that?

I read that when you see the holes, the woodworm have left.

Yes, amongst the all the dust and crap on the ground there's a small amount of sawdust that stands out because it's much lighter than anything else downthere.

Then def treat all the areas as a precaution at the very least...

Sure looks like woodworm. I believe they have a 3-yr life cycle. Even if adults have vacated the holes there could still be grubs in the wood; unless those are very old holes. Best to treat it anyway, as a preventative if not a cure.

Thanks everyone, I'll get onto treating it ASAP.
