The doll collection was for the wife of the owner of one of the NE Hockey teams. (Their bedroom was bigger than my entire house...) Nice people, she liked pre-1920 European dolls, primarily German & French... a little Spanish tossed in for fun. They developed an infestation of Golden Casemaking Clothing Moths. Nasty little buggers, very hard to get rid of. Ultimately, they went fumigation. I had advised against it. Some of the wax dolls were damaged as were some period clothing from the treatment. On the other hand; after about 3 months we had successfully eliminated the problem in the home. The house itself was treated with a combination of pheromone traps, IGR's and other materials. In essence; everything fabric in the house had to be dry-cleaned. It was a battle. (usually with homeowner compliance with my instructions) If your freezers reach -80C. that will do it. Remember that emergence of adults is contingent upon a multitude of environmental factors. Heat, moisture content of the wood, humidity even starch content of the cellulose fibers that actually constitutes 98% of wood is critical. I've seen wood-boring beetles emerging from kiln-dried lumber 4 years after being installed in a house!!!
