(perhaps the pyrethroid which can stop the moth attack cannot be added in a dry process)
Aren´t pyrethroids those superpersistent supertoxines, that make you tear down the whole house when you ever want to get rid of them, in contrast to natural permethrin, or do I confuse things here?
Can I expect to find pyrethroids in any comercial wool product unless it´s certified organic?
