I could post pics of moth damage from nearly every piano I service – so ubiquitous is the problem now! (See other posts)
On this Yamaha C7 from the 1970s, the monsters had progressed from their usual starting place, the back-touch baize & underfelt, to continue feasting on the lever foot felts:
Moth Munch Crater…
The best recommended prevention is the placing of Rentokil Moth Repellent Strips (or equivalent) somewhere inside the piano, here shown on top of the plate (of a Grotrian-Steinweg concert grand):

An impressive share! I have just forwarded this onto a co-worker who was doing a little research on this.
And he actually bought me breakfast due to the fact that I discovered
it for him… lol. So let me reword this…. Thanks for the meal!!
But yeah, thanks for spending some time to discuss this
subject here on your site.
First of all I want to say fantastic blog!
I had a quick question in which I’d like to ask if you
do not mind. I was interested to find out how you center yourself and clear your head prior to writing.
I’ve had a tough time clearing my mind in getting my thoughts out.
I do enjoy writing however it just seems like the first 10 to
15 minutes are usually lost just trying to figure out how to
begin. Any recommendations or hints? Thank you!
