Top 4 Best Non-Toxic Mothballs & Pest Control
4 products independently rated for safety, effectiveness, and value — ranked and reviewed by PollutionProfile.
Traditional mothballs use naphthalene or paradichlorobenzene — toxic chemicals classified as possible human carcinogens that contaminate indoor air and linger in fabric. We rated 7 of the best natural moth repellent alternatives using cedar, lavender, and diatomaceous earth on repellency effectiveness, safety, and scent longevity. Protect your clothes without poisoning your closet.
