Well, it's a moth infestation.
Luckily nothing has shown up on the traps ine the basement where most fo the old wool is. And only one on teh 1st floor (right by the stairway), but 7 male moths on the 2nd floor.
So I am now moving the traps between all the 2nd floor rooms with the doors shut to see if one seems to have a greater number than the rest.
Then I have to figure out the life cycle of the clothing moth so as to make sure I try and nail all the next batch of males before they fertilize the females.
There is somethign to be said for collecting modern stuff- moths do not eat cotton or nylon.
