I think I might have wardrobe moths. I am not sure it's them but I have noticed two holes in two of my cotton and linen tshirts over the past week. Seems like a coincidence that it happened to more than one item in a short space of time. I already use cedarwood disks (although I hadn't refreshed them for a few months) but is there anything else I can do to keep them away? Also, what is an adequate quantity of cedarwood I need to use? I have a small double wardrobe and a couple of shelves.
Thank you!
