Reddit reviews Willert Home Products Enoz Moth Cake with Hanger, (3 Pack)

They're tiny bugs, not even really like the moths you see outside, and I think the holes are actually made by the larvae after they hatch. Doubt you'll ever see one alive. My wife has a much bigger (and more expensive) wardrobe than me so she has mothballs and cedar planks in both our closets as repellent. There are also traps you can use in conjunction with mothballs.
