[Cob] Woodworm treatment (Susan Hagan)

[Dean Sherwin]

I had an old barn I converted (in the US) and there was infestation 
that seemed to be still active, I treated it with liberal 
applications of a penetrating oil, I do not think I used anything 
very toxic.  But that was I think powder post beetles, whereas you 
being in Europe more likely have as you say woodworm, anobium 
punctatum.  We used to painstakingly treat that with a small brush 
and furniture beetle oil (Rentokil brand in UK) pushing it into each 
hole especially if active (you can tell by the newness of the wood) 
(If the holes are dark and old, don't bother)  But honestly I do not 
know if it is necessary to be so fastidious.   the other experience 
makes me think it may be enough to saturate the wood as much as 
possible with a pesticide oil. Or maybe just a penetrating type of 
oil.   Perhaps your neighbors know what is effective there. It takes 
a good deal of infestation to make oak beams structurally unsound.
