Here is another question asked by a member of the public relating to timber treatment. We hope that it and the answer, which we include below, are useful.

I cleared out my garage after 15 years or so. I found my old fishing creel – willow I think – "eaten" away so as bits of it were crumbly and a fine powder was evident along with tiny round holes.

This was no problem as I just threw it away, but I am now wondering if I should treat the bench it was standing on as there are a few holes evident. Also, could it spread indoors? Would the insect attack a painted surface like the door into the  house which was close to the creel?

It is only a small area at risk, but any advice would be helpful.

Here's our answer:

It sounds as if the creel has been attacked by Powder Post Beetle. Take a close look at timbers near where the creel was stored and check for bore holes. If necessary treat these areas with Micro 8I. As regards the door again check for bore holes. It is unlikely that you will find any on a vertical painted  surace. These beetles do not fly too far so I think the house will be safe.
