We found the problem in several pianos - but only in Asian ones: Yamahas and the Korean Kohler & Campbells, all about 10 years old. No problems with American pianos - and we do have lots of much older Steinways, Baldwins, Wurlitzers and Everetts at the school. So we suspect that the critters are imported with the pianos from the source country and are not a local infestation. I hear that this is common. Since there are no wool furnishings around here - curtains, stuffed chairs, carpets, etc. - I don't see how these critters would spread from piano to piano. Add I don't see moths flying around. But then there is the theater department on the other end of the building - costume shop, wardrobe, prop storage... Hmm... Maybe I should check with them about moth damage in their stuff... Yamaha sent us a bunch of replacement punchings free - but I hesitate to put them in pianos, since they might be the source of the infestation... Maybe fumigating them with or dipping them in one of the suggested substances before use might be a good idea? Israel Stein.
