If you want to use mosquitoes in a sentence, the main thing to remember is simple: mosquitoes is a plural noun. That means it usually refers to more than one insect and normally takes a plural verb, such as are, buzz, bite, or gather. Dictionaries define mosquito as a noun and list mosquitoes as a standard plural form, with mosquitos also accepted as a variant.
Quick Answer
Use mosquitoes when you mean more than one mosquito. It works naturally as the subject of a sentence, the object of a verb, or the object of a preposition. Write sentences like Mosquitoes are everywhere tonight or We kept the windows closed to keep out mosquitoes. That fits standard dictionary usage and common example patterns.
What The Term Means
Mosquitoes means the plural of mosquito, a small flying insect known for biting people and animals. Major dictionaries define mosquito that way and show mosquitoes as a regular accepted plural form. Some dictionaries also accept mosquitos, but mosquitoes is the form used in your keyword and the safest one to follow here.
How It Works In A Sentence
Because mosquitoes is plural, it usually appears with plural grammar.
You can use it as the subject of a sentence: Mosquitoes come out at dusk.
You can use it as the object of a verb: Campers hate mosquitoes.
You can use it after a preposition: We sprayed the yard for mosquitoes.
You can also use it in descriptive phrases: mosquitoes near the lake, mosquitoes in the basement, or mosquitoes around the porch.
What usually sounds wrong is treating mosquitoes like a singular word. For example, Mosquitoes is annoying is incorrect because a plural noun needs a plural verb: Mosquitoes are annoying. Dictionary examples consistently show plural use in phrases such as a swarm of mosquitoes and sentences like Stay indoors when mosquitoes are out.
Common Sentence Patterns
| Sentence Pattern | Example | Why It Works |
| Mosquitoes + plural verb | Mosquitoes are worst near the creek after rain. | The noun is plural, so the verb is plural. |
| Verb + mosquitoes | We noticed mosquitoes as soon as the sun went down. | Here, mosquitoes is the object of the verb noticed. |
| Preposition + mosquitoes | They packed extra spray for mosquitoes. | The noun fits naturally after a preposition. |
| Adjective + mosquitoes | Those mosquitoes were relentless. | The determiner and plural noun agree. |
| Mosquitoes + location phrase | Mosquitoes around the trash cans got bad fast. | A location phrase adds detail and makes the sentence sound natural. |
| Mosquitoes + action verb | Mosquitoes gathered near the porch light. | Plural nouns pair well with action verbs when describing behavior. |
Natural Example Sentences
Here are natural ways to use mosquitoes in everyday English:

These examples sound natural because mosquitoes is doing clear sentence work each time. It names a group, matches a plural verb when needed, and fits common real-life contexts such as weather, camping, yards, windows, and summer evenings.
Formal Vs Informal Use
Mosquitoes is a neutral word. It works in both formal and informal writing.
In everyday conversation, you might say, The mosquitoes are terrible tonight.
In a more formal sentence, you might write, Mosquitoes are most active in warm, damp conditions.
The word itself does not change across formal and informal settings. What changes is the rest of the sentence. Casual sentences often sound shorter and more direct. Formal sentences usually sound more precise and informational.
Common Mistakes (and Fixes)
One common mistake is using a singular article with a plural noun.
Incorrect: A mosquitoes kept landing on the window.
Correct: A mosquito kept landing on the window.
Correct: Mosquitoes kept landing on the window.
Another mistake is using a singular verb.
Incorrect: Mosquitoes is everywhere tonight.
Correct: Mosquitoes are everywhere tonight.
Another problem is choosing mosquitoes when you really mean one insect.
Incorrect: A mosquitoes bit me.
Correct: A mosquito bit me.
Some writers also build awkward sentences by leaving the noun too vague.
Awkward: Mosquitoes were there.
Better: Mosquitoes were swarming near the patio door.
The fix is usually simple: make sure the number is right, the verb agrees, and the sentence gives enough context to sound complete.
Similar Uses Readers Confuse
Writers often confuse mosquitoes with mosquito, mosquito bites, and mosquitos.
Use mosquito when you mean one insect: A mosquito landed on my arm.
Use mosquitoes when you mean more than one: Mosquitoes kept circling our heads.
Use mosquito bites when the sentence is about the marks or irritation, not the insects themselves: She covered her mosquito bites with lotion.
You may also see mosquitos. Major dictionaries accept it as an alternate plural, but they also list mosquitoes, which is the form most readers expect in this kind of usage guide.
Quick Usage Tips
Think plural every time you use mosquitoes.
Pair it with plural verbs like are, bite, buzz, swarm, or gather.
Use it when the sentence clearly involves more than one insect.
Add context that makes the sentence feel real, such as a place, time, or reaction: near the lake, after dark, around the porch, kept us awake.
If the sentence sounds flat, make it more specific. Mosquitoes were annoying works, but Mosquitoes were swarming around the garbage bins sounds sharper and more natural.
When The Term Sounds Unnatural
Mosquitoes can sound unnatural when the sentence does not need a plural noun.
For example, There was mosquitoes in the room sounds wrong because the grammar does not match. There were mosquitoes in the room fixes it.
It can also sound weak when the sentence is too broad.
Vague: Mosquitoes are bad.
Better: Mosquitoes are especially bad after heavy rain.
Sometimes the better choice is not mosquitoes at all. If you mean one insect, use mosquito. If you mean the result of being bitten, use mosquito bites. If you mean bugs in general, insects may fit better.
Conclusion
To use mosquitoes in a sentence, treat it as a plural noun and match it with plural grammar. It works best in clear, concrete sentences such as Mosquitoes are buzzing near the porch or We used repellent to keep mosquitoes away. Stay aware of number, verb agreement, and context, and the word becomes easy to use naturally. If you keep one rule in mind, make it this: mosquitoes means more than one, so the rest of the sentence should reflect that.
