Mothballs are not an air freshener or a general animal repellent — they’re a registered pesticide that slowly releases toxic vapor, and they’re meant for one narrow job: protecting stored clothing from clothes moths in a sealed container. Used the way TikTok suggests (in gardens, attics, or crawlspaces to repel pests), they’re both illegal and a genuine health hazard.
Key Takeaways
- Mothballs are a pesticide (naphthalene or paradichlorobenzene), not a deodorizer.
- Use only as labeled — in a sealed container with clothing, never in open spaces.
- Using them to repel other animals is illegal and unsafe — the vapors are toxic to people and pets.
- For pantry moths, they do nothing — sanitation and pheromone traps are the answer.

Type of Moths
Two types of mothballs are available: one with naphthalene and the other with paradichlorobenzene as active ingredients.
Despite the difference in chemicals, their effectiveness in repelling moths is comparable. Both chemicals convert into gases that mix with the air and kill moths.
However, long-term exposure to these gases can lead to headaches, nausea, eye and nose irritation, and coughing.
To prevent this, it’s crucial to store mothballs with clothes in an airtight container and follow all label instructions carefully.
Myths of Mothballs
Myth of Snake Repellent: There is a common belief among many people that mothballs can effectively repel snakes, mice, and other animals.
However, it is essential to dispel these misconceptions as they are merely fictitious tales. In reality, mothballs are designed to eliminate Moths and Carpet Beetles, not to repel animals.
Using mothballs to deter animals around your home poses potential risks, especially when placed in various areas accessible to children.
Mistaking them for candies, children may accidentally consume these toxic substances. Therefore, it is crucial to exercise caution and avoid using mothballs for animal-repellent purposes.
Use mothballs only as the label directs
It’s worth repeating because misuse is so common: mothballs work by filling an enclosed space with pesticidal vapor, so they only do their job in a sealed container with the clothing you’re protecting. Scattering them in attics, gardens, or crawlspaces to drive off squirrels, snakes, or other animals is against the label (and therefore illegal) and exposes your household to toxic fumes (EPA: Mothball safety). Keep them away from children and pets, who can mistake them for candy. For pantry/food moths, skip mothballs entirely — clean out the infested food and use pheromone traps.
