Mothballs are usually called bolas de naftalina in Spanish; naftalina also works for the product.
If you’re learning Spanish for home, travel, shopping, or class, mothballs are one of those odd household words that can trip you up. The direct idea is simple: small balls or tablets used to keep moths away from stored clothes. The Spanish wording changes a little by shape, region, and setting.
The safest everyday translation is bolas de naftalina. Many Spanish speakers also shorten it to naftalina, mainly when the product is already clear from the sentence. If you’re asking in a store, reading a label, or writing a class sentence, those two choices will handle most cases.
Saying Mothballs In Spanish With The Right Word
The phrase bolas de naftalina means “balls of naphthalene,” which is the traditional wording tied to mothballs. Spanish often names the material rather than translating the English image word by word. That’s why bolas de polilla sounds wrong to many speakers, since it would mean “moth balls,” not the product used against moths.
For a single mothball, say una bola de naftalina. For several, say bolas de naftalina. If the product comes as tablets, blocks, or cakes, pastillas de naftalina may sound more exact. In a store aisle, you may also see antipolillas, which points to moth-repellent products as a category.
Why Literal Translation Sounds Odd
English makes “mothballs” feel like one fixed noun. Spanish treats the item as a small object made from, or linked to, naftalina. The word polilla means moth, but it usually names the insect, not the storage product.
So a sentence like “I bought mothballs” can be translated as compré bolas de naftalina. If you say compré polillas, you’re saying you bought moths. That small swap changes the whole meaning.
Best Spanish Terms For Store, Class, And Daily Speech
Pick your Spanish term based on what you’re doing. In casual speech, naftalina is short and natural. In a classroom answer, bolas de naftalina is clearer. On packaging, antipolillas may appear because the item’s job is to protect clothing from moths.
When speaking with a shop worker, ask for bolas de naftalina first. If they point you toward sprays, sachets, or cedar blocks, they may group them under antipolillas. That term is handy, but it doesn’t always mean classic white mothballs.
Pronunciation Help
Bolas de naftalina sounds like BOH-lahs deh nahf-tah-LEE-nah. The stress lands on LEE in naftalina. Say it slowly at first, then link the words: bolas de naftalina.
Antipolillas sounds like ahn-tee-poh-LEE-yahs in many accents. The double ll is often close to an English “y,” though some regions pronounce it more like “j” or “sh.” If you want the classic product, don’t rely on pronunciation alone; include naftalina.
Common Wording Choices And When They Fit
The table below gives practical choices for different settings. It also helps you avoid stiff or mistaken wording when you write a sentence, speak with a clerk, or translate a label.
| Spanish Wording | Best Setting | Meaning And Note |
|---|---|---|
| Bolas de naftalina | General speech and writing | The clearest term for classic mothballs. |
| Una bola de naftalina | Singular item | Use this for one mothball. |
| Naftalina | Casual speech | Short term for the product or substance. |
| Pastillas de naftalina | Tablets or cakes | Better when the shape is not round. |
| Antipolillas | Store labels | A moth-repellent product, not always classic mothballs. |
| Repelente para polillas | Plain description | Means moth repellent; good when product type is unknown. |
| Producto contra polillas | Broad product wording | Useful for sprays, sachets, blocks, and balls. |
| Bolas antipolillas | Some product listings | Means anti-moth balls; clear in shopping text. |
Sample Sentences That Sound Natural
Sample sentences make the word easier to store in memory. They also show how Spanish speakers place the phrase inside normal grammar.
Necesito comprar bolas de naftalina para el armario. This means “I need to buy mothballs for the closet.” It works well in a shop, at home, or in a lesson.
Mi abuela guardaba la ropa con naftalina. This means “My grandmother stored clothes with mothballs.” Here, naftalina stands alone because the storage product is clear.
No pongas naftalina cerca de la comida. This means “Don’t put mothballs near food.” It sounds natural because Spanish often treats naftalina as the substance or product.
Busco un producto antipolillas para ropa de lana. This means “I’m looking for a moth-repellent product for wool clothing.” This sentence helps when you don’t care whether the item is a ball, sachet, block, or spray.
Singular And Plural Forms
Spanish marks number clearly. One mothball is una bola de naftalina. Two or more are bolas de naftalina. The word bola is feminine, so the article is una, not un.
If you’re talking about a box of mothballs, say una caja de bolas de naftalina. If you’re talking about the smell, say olor a naftalina. That phrase is common because mothballs have a sharp, old-closet smell many people recognize at once.
Regional Notes For Spanish Speakers
Spanish varies by country, and household words can shift from one region to another. Naftalina is widely understood, but store shelves may prefer safer category words such as antipolillas or repelente para polillas. Product labels may also avoid old chemical wording when the formula uses another active substance.
In many places, naftalina can mean the smell, the chemical, or the old-style mothball product. That can be useful, but it can also be too broad. If you need the physical item, add bolas or pastillas.
| Situation | Phrase To Say | Why It Works |
|---|---|---|
| Asking in a shop | ¿Tiene bolas de naftalina? | It names the item directly. |
| Reading a label | Antipolillas | It marks the product category. |
| Writing a school sentence | Bolas de naftalina | It is clear and standard. |
| Talking about smell | Olor a naftalina | It points to the scent, not the shape. |
| Describing tablets | Pastillas de naftalina | It fits non-round pieces. |
Mistakes To Avoid With Mothball Vocabulary
Don’t translate the English word piece by piece. Bolas de polilla may be understood after a pause, but it sounds like the balls belong to a moth. Use naftalina when you mean the storage product.
Don’t use mariposa for mothballs. Mariposa means butterfly in most everyday Spanish. A moth is usually polilla, especially the kind that damages clothing.
Don’t assume antipolillas always means the old white balls with a strong smell. It can mean spray, paper strips, cedar pieces, hanging sachets, or another product made for clothing storage.
Safety Wording In Spanish
Mothballs are not candy, air fresheners, or drawer perfume. If you’re translating safety text, use direct Spanish. Try mantener fuera del alcance de niños y mascotas for “keep out of reach of children and pets.”
For food safety, no usar cerca de alimentos means “do not use near food.” For storage, usar solo según las instrucciones de la etiqueta means “use only as directed on the label.” These lines are plain, clear, and fit real packaging tone.
How To Remember The Spanish Word
Link naftalina with the smell of old stored clothes. That scent clue is often stronger than a word list. Then add the shape word when needed: bola for ball, pastilla for tablet, and producto for a general item.
You can build three short cards for practice. Card one: mothballs = bolas de naftalina. Card two: moth = polilla. Card three: moth repellent = antipolillas. Read them aloud, then place each one in a sentence about clothes, closets, or wool.

Final Word Choice
For most learners, the best answer is bolas de naftalina. It is specific, widely understood, and safe for classwork, shopping, and translation. Use naftalina when the product is clear, and use antipolillas when you mean the wider group of moth-repellent products.
If you only learn one form, learn bolas de naftalina. It gives you the object, the meaning, and the natural Spanish wording in one phrase.
