Thanks! Susan
There was a post about this on a different bulletin board. I think they are
similar or the same as dust-mites. One method was to take your clarinet case
and stick it in the freezer for two weeks to freeze them and their eggs to
death. The other method was to buy a new case!

I think they're a good deal larger than mites!
I've often found empty larval capsules in the bore of old instruments,
which implies a chrysalis stage - so I would suggest it's a moth
that's the culprit. Certainly the typical damage to the pads indicates
a larvae of a size quite visible to the naked eye ( though I have
never actually seen one personally ).
On the whole their occurrence is rare - it's unlikely that instrument
pads are their food of choice, and I certainly can't recall ever
seeing any such damage on an instrument in regular use.
As for the origins of the larvae - well, either the female adults fly
in and lay their eggs in your case when your back is turned.... or the
eggs are already incorporated into the fabric of the case during
manufacture ( and perhaps in the felt of the pads too? ).
Such eggs can lie dormant for some considerable time whilst waiting
for the right conditions in which to hatch.
I'm not sure that freezing the eggs will work.... any gardener will
assure you that even the fiercest of winters fails to kill all the
bugs - so one must assume a degree of tolerance to freezing in insect
eggs.
I'm pretty sure there must be some proprietary treatments for moth
larvae on the market ( I'd avoid mothballs though! ).

I don't believe I have replaced any in the last 20 years or so
and they seem to be still good for another 50 years or so. It's
a cheap fix that works.
