Ok, new problem. A large bear rug has visible, live dermestids in the fur. That tells me they are not only on the fur side but more than likely on the back, between the hide and the felt backing. Will a dry cleaning place that advertises they do furs be able to deal with this or is there another way? Pest treatment company? The rug is already needing some rather extensive repair/restoration work but the hitchhikers need to be all dead quick. Thanks for any input. Did a quick search but didn't find much that was helpful. Not sure if mothballs will kill these things, especially since it needs to penetrate between the layers of backing. Looking for helpful info as to what to do to insure all the bugs are dead before I proceed with restoration work. Going to put it in a freezer for now. Wondering if an extended stay in the freezer will also kill them .. and any eggs.
