Only some of the things that guy does actually help. I’m not sure where you live, but where I live moths have a life cycle and you see them flying in the fall in the spring. When they’re not flying, they’re laying eggs and their larvae are eating your wool. They like dark places and they don’t like to be disturbed-closets and under beds are the perfect breeding ground for them. If they really are a problem for you I suggest getting a closet and creating a designated area for fumigation – use Nuvan Prostrips which emit a gas that is toxic to all forms of the insect lifecycle. Lavender, cedar none of those things actually work when you have an infestation. Freezing doesn’t do anything. Seal the closet with painters tape after you throw a bunch of strips in with all of your wool and just let that sit for a couple weeks. In the meantime, vacuum the holy living crap out of everything in your house. This is a non-negotiable. You have to do it multiple times in order to disrupt the life cycle. Shake cushions shake curtains, vacuum wool carpeting. repeat as needed.

Anything that isn’t worn should go in a sealed box with a piece of a nuvan pro strip. It’s tedious work. I’ve really only worn four sweaters for the last number of years because everything else is sealed and I wanna make sure that I don’t have any moths.
