It was 3 AM in my first Shanghai summer when I learned the most urgent vocabulary of my life: a high-pitched whine circling my ear, lights on, me standing on the bed with a slipper. I did not know the word for my enemy. Now I do, and so will you: how to say mosquito in Chinese is 蚊子 (wén zi), the small word behind a very large part of summer in China.
蚊子 is survival vocabulary, not trivia. You need it at the pharmacy buying repellent, at the hardware store buying coils, in the group chat complaining about bites, and occasionally at the clinic explaining why your arm has eleven itchy bumps. China’s anti-mosquito arsenal is also genuinely different from what most expats know: mosquito coils, electric swatters, floral water, and bed nets all have their own words.
This guide covers the full picture: what 蚊子 literally means, the crucial difference between 叮 and 咬 (two kinds of “bite”), the complete anti-mosquito shopping vocabulary, how to complain about bites like a local, and the health words worth knowing in dengue season.

Key Takeaways
- 蚊子 (wén zi) is mosquito. The bite verb is 叮 (dīng), not 咬: you say 我被蚊子叮了 (I got bitten by a mosquito).
- The arsenal: 驱蚊液 (repellent spray), 蚊香 (mosquito coils), 电蚊拍 (electric swatter), 蚊帐 (bed net), 花露水 (floral water, the classic Chinese after-bite splash).
- In southern China, take bites plus fever seriously: 登革热 (dèng gé rè, dengue) peaks in late summer and autumn and needs a doctor, not just itch cream.
The Basics: Breaking Down 蚊子 (wén zi)
Character Meaning
蚊子 is a two-character word where only the first character does the work:
- 蚊 (wén), mosquito. Look at the left side: the 虫 (chóng) radical means insect, and it appears in the characters for fly (苍蝇), ant (蚂蚁), and spider (蜘蛛). The right side, 文 (wén, language/culture), is purely the sound component: 蚊 sounds like 文.
- 子 (zi), a neutral-tone noun suffix with no meaning of its own here, the same 子 as in 鼻子 (bí zi, nose) and 孩子 (hái zi, child).
The dict.cn entry for 蚊子 glosses it plainly as “mosquito,” and confirms the spoken form is always wén zi with the light second syllable, never wén zǐ in conversation.
Pronunciation Guide
蚊子 is pronounced wén zi: second tone, then a light neutral tone:
- wén, rises like a question: “wén?” Identical in sound to 文 (language) and 闻 (to smell/hear), which is a nice mnemonic: the mosquito is the insect you HEAR.
- zi, neutral tone, short and unstressed. Do not give it a full third tone; in natural speech it is a quick little tap after wén.
Say it as WEN-zuh, with the second syllable almost swallowed. If you stress the zi, people still understand you, but the light ending is what makes it sound local.
叮 vs 咬: Two Ways to Get Bitten
Chinese has two different verbs for “bite,” and mosquitoes get their own:
- 叮 (dīng), the piercing bite of mosquitoes and other small insects. The 口 (mouth) radical plus 丁. This is THE mosquito verb.
- 咬 (yǎo), the biting of teeth: dogs, people, apples. Big jaws, not proboscises.
- Chinese: 我昨晚被蚊子叮了好几个包。
- Pinyin: Wǒ zuó wǎn bèi wén zi dīng le hǎo jǐ ge bāo.
- English: I got several mosquito bites last night. (Note 包, “bump,” the word for the bite itself.)
- Chinese: 别抓，越抓越痒。
- Pinyin: Bié zhuā, yuè zhuā yuè yǎng.
- English: Don’t scratch; the more you scratch, the itchier it gets. (The 越…越… pattern, in its most universal use case.)
Common Uses and Contexts
Buying Mosquito Protection
Every convenience store and supermarket in China stocks a mosquito aisle from May to October. The labels to recognize:
- 驱蚊液 (qū wén yè), mosquito repellent spray. 驱蚊 = “repel mosquitoes.” Also sold as 防蚊喷雾.
- 花露水 (huā lù shuǐ), floral water, the green bottled splash every Chinese grandmother swears by; used before bites as mild repellent and after bites for itch.
- 蚊香 (wén xiāng), mosquito coil (香 = incense); the spiral you light, or the electric plug-in version 电蚊香.
- 电蚊拍 (diàn wén pāi), the electric mosquito swatter racket; the most satisfying 15 yuan you will spend in China.
- Chinese: 请问，驱蚊液在哪里？
- Pinyin: Qǐng wèn, qū wén yè zài nǎ lǐ?
- English: Excuse me, where is the mosquito repellent?
- Chinese: 这个电蚊拍多少钱？充电的吗？
- Pinyin: Zhè ge diàn wén pāi duō shao qián? Chōng diàn de ma?
- English: How much is this electric swatter? Is it rechargeable?
Defending Your Apartment
The home defense vocabulary turns out to be the difference between sleeping and not sleeping:
- 蚊帐 (wén zhàng), mosquito net, draped over the bed. Old-school, chemical-free, and weirdly cozy.
- 纱窗 (shā chuāng), window screen. Check them when you view apartments: 纱窗有没有破洞 (does the screen have holes?).
- 打蚊子 (dǎ wén zi), to swat mosquitoes; the 3 AM activity from my introduction.
- 关窗 (guān chuāng), close the window, the first rule of dusk in summer.
- Chinese: 房间里有一只蚊子，我睡不着。
- Pinyin: Fáng jiān lǐ yǒu yì zhī wén zi, wǒ shuì bù zháo.
- English: There is a mosquito in the room and I can’t sleep. (一只, the measure word for small creatures.)
Complaining About Bites
Complaining about mosquitoes is a bonding ritual in China, and these phrases make you sound like a local rather than a tourist with a phrasebook:
- 我被蚊子叮了 (wǒ bèi wén zi dīng le), I got bitten by a mosquito. The 被 (bèi) passive, in its most-used everyday form.
- 好痒 (hǎo yǎng), so itchy. If the itch will not stop, that is 过敏 territory; our allergy vocabulary guide covers the pharmacy conversation.
- 蚊子包 (wén zi bāo), the mosquito bite bump itself.
- O型血招蚊子, “type O blood attracts mosquitoes,” the folk belief you will hear at every barbecue.
- Chinese: 我怎么这么招蚊子？腿上全是包。
- Pinyin: Wǒ zěn me zhè me zhāo wén zi? Tuǐ shàng quán shì bāo.
- English: Why do mosquitoes love me so much? My legs are covered in bites.

Health: Dengue and When to Worry
Most bites are just itchy, but southern China (Guangdong, Yunnan, Guangxi, Hainan) has real dengue seasons, typically August to October. The words that matter:
- 登革热 (dèng gé rè), dengue fever, the phonetic transliteration of “dengue.”
- 发烧 (fā shāo), to have a fever; bites plus fever plus joint pain means see a doctor, same day.
- 蚊虫叮咬 (wén chóng dīng yǎo), insect bites, the formal phrase on clinic signs and medicine packaging.
- Chinese: 我被蚊子叮了以后发烧了，要不要去医院？
- Pinyin: Wǒ bèi wén zi dīng le yǐ hòu fā shāo le, yào bú yào qù yī yuàn?
- English: I developed a fever after being bitten by mosquitoes; should I go to the hospital? (In dengue season, the answer is yes.)

The 蚊 Family: Mosquito Words
蚊 heads a compact family of practical compounds, all of which you will meet in a single Chinese summer:
- 蚊香 (wén xiāng), mosquito coil.
- 蚊帐 (wén zhàng), mosquito net.
- 驱蚊 (qū wén), mosquito-repelling, as in 驱蚊液 and 驱蚊手环 (repellent wristband).
- 蚊虫叮咬 (wén chóng dīng yǎo), insect bites (formal/medical).
- 灭蚊 (miè wén), mosquito extermination; 灭蚊灯 is the zapper lamp.
Cultural Context: China’s War on Mosquitoes
Mosquito defense in China is a whole culture. Summer evenings in any park feature grannies armed with 电蚊拍 swatters, blue sparks crackling like tiny thunderstorms. Corner shops stack green bottles of 花露水 floral water by the register, and older apartments still keep foldable 蚊帐 nets in the closet. The Beijinger’s mosquito myth-busting piece captures the expat experience well, including why those ultrasonic phone apps do nothing and why the low-tech solutions still win.
On the public-health side, mosquito control is serious business in the south, where 登革热 dengue appears every late summer and autumn. Cities run fumigation campaigns, housing compounds drain standing water (积水, stagnant water, the breeding ground), and some parks now advertise themselves as mosquito-free zones with smart traps. For expats the practical takeaway is simple: stock 驱蚊液 in May, check the 纱窗 when you sign a lease, and keep the number for a clinic handy in September and October, especially if you are in Guangdong or Yunnan.
Common Mistakes to Avoid
- Saying 咬 for mosquito bites. 我被蚊子咬了 is understandable but marks you as a learner. The mosquito verb is 叮: 我被蚊子叮了.
- Pronouncing 蚊子 as wén zǐ with two full tones. The second syllable is neutral and light: WEN-zuh. A heavy zǐ sounds robotic.
- Calling repellent 杀虫剂. 杀虫剂 (shā chóng jì) is insect killer spray, the chemical fog for cockroaches. Skin-safe repellent is 驱蚊液 or 花露水. Do not spray 杀虫剂 on your arms.
- Using 个 instead of 只. Mosquitoes take the measure word 只: 一只蚊子, not 一个蚊子.
- Ignoring bites-plus-fever in the south. In dengue season (roughly August to October in Guangdong and Yunnan), a fever after bites is a doctor visit, not a wait-and-see.

Frequently Asked Questions
What is the difference between 叮 and 咬?
Both mean “bite,” but 叮 (dīng) is for mosquitoes and other small piercing insects, while 咬 (yǎo) is biting with teeth (dogs, people, food). The natural way to say “a mosquito bit me” is 我被蚊子叮了. Using 咬 is understandable but instantly marks you as a learner.
What is mosquito repellent called in Chinese?
The standard term is 驱蚊液 (qū wén yè, “repel-mosquito liquid”), also sold as 防蚊喷雾 (anti-mosquito spray). For after-bite relief, locals reach for 花露水 (huā lù shuǐ, floral water), the classic green-bottle splash found in every Chinese corner store. Never confuse these with 杀虫剂, which is chemical insect killer, not skin-safe.
Are mosquitoes a serious health risk in China?
In most of China, bites are just itchy annoyances. But southern provinces (Guangdong, Yunnan, Guangxi, Hainan) have annual dengue (登革热) seasons, usually peaking August to October. If you develop a fever (发烧), joint pain, or a rash after bites in those regions, see a doctor promptly and mention the bites.
What is 花露水 and do I need it?
花露水 (huā lù shuǐ, literally “flower dew water”) is a lightly medicated floral splash that every Chinese household keeps in summer: applied before going out as a mild repellent and after bites to calm the itch. The classic brand is 六神 (Liushen). It is cheap, everywhere, and a genuinely useful piece of local knowledge.
What is the measure word for mosquito?
Use 只 (zhī), the measure word for small animals and insects: 一只蚊子 (one mosquito), 房间里有一只蚊子 (there is a mosquito in the room). In casual speech about bites you will also hear 个 for the bumps: 叮了好几个包 (got several bites).
