Mothballs in attic odor.
To get rid of this smell it s recommended that you never use any sort of air freshener to cover up the smell.
This will almost always result in a persistent and noxious odor throughout the home alternative ways to control clothes moths are available for those who prefer not to use chemical treatments.
Indeed the odor from mothballs is a voc like substance paradichlorobenzene or naphthalene that quite penetrates many materials including even drywall furnishings carpeting and it can take quite a while for it to diminish.
Mothballs are a common home remedy due to their pesticidal properties and ability to negate other bad smells.
I do not believe mothballs got into the walls maybe a few but not many.
Charcoal will soak up odors as well and help remove the moth ball smell.
Put out a bowl of vinegar or coffee grounds to help absorb the odor.
Naphthalene mothballs can take many months for the odor to go away while p dcb usually evaporates away within a month.
A relatively common mistake is placing mothballs in an attic to repel squirrels.
Well here is the weird thing the smell is almost completely gone from the attic but the house reeks so bad that we can t stay there.
My guess is that the moth ball vapors are heavy and sinking into the house.
