Remove Mothball Smell from Closets and Rooms
The odor can be particularly stubborn in rooms or closets where mothballed clothes have been stored. To remove these odors, leave out bowls of vinegar or plates of
activated charcoal in the affected areas. (Activated charcoal is sold in various pellet sizes and is usually available at pet stores.) You can also try placing containers of coffee grounds or odor-absorbing candles for similar results. Whichever material you choose, place it in the areas with the heaviest smells, and change it often until the smell is gone.
