How do I get rid of moths for good?

Adult moths aren’t actually the ones who eat fabric, it’s the larvae. So, if you’re seeing holes in your clothes and you’ve seen adult moths, you have larvae in your closet. Mothballs will 100% work if you don’t mind the aroma. You can also fill your home with cedar. Moths absolutely despise the aroma of cedar wood. Just pick up some cedar planks at the store and leave them in your closet. If you are worried about larvae and juvenile moths, which it sounds like you should be, just wash all of your clothes. Anything that’s hanging in your closet or in your drawers—take them out and wash them. That will kill any larvae on your clothes.

Your clothes are their food source. If you want to get rid of the moths, take their food source away from them. Take all of your wool clothing and put them in plastic bags, then stick them in the freezer so the moths can't get them. While your clothes are put away, you can take the chance to vacuum all the crevices in your closet. Give it a few days then wash all of your clothes. Moths should be gone!

In addition to cedar, another great natural remedy for getting rid of moths is lavender. I like the smell a lot better and it's also effective. You can get lavender satchets or balls and place them throughout your closests, dressers, and other clothing storage places.

Have you tried moth traps? They worked great for me and you can get them for pretty cheap.
