What Time Are Mosquitoes Most Active?

Mosquitoes are pesky insects that seem to be present whenever you and your family decide to have an outdoor adventure.

Some mosquitoes are active between the hours of 5 am up to 7 am, and then there are genera of mosquitoes that are active just before the sunset in the hours from 4 pm to 7 pm.

The most alarming is that there are decease-spreading mosquitoes active during night-time, dusk, and down.

You may prevent mosquitoes from feasting on you and your family or friends by avoiding their preferred feeding periods. This post will provide you with information that can help you in dodging these blood-suckers.

When Are Mosquitoes Most Active?

In general, mosquitoes are active during sunrise and sunset because these are the time of the day when they can tolerate the heat of the sun.

Studies show that mosquitoes are rarely active in the middle of the day because direct exposure to the heat of the sun will dehydrate them. This will then lead to death.

However, these are not the only factors that influence when are mosquitoes most active. Their activity will also be dependent on the weather, species, and temperature.

Mosquitoes tend to avoid the hours of the day between 11 am to noon as the temperature is high during this time of the day. The ideal temperature for mosquitoes is between 80 to 90 degrees Fahrenheit.

Top 4 Mosquito Genera and Their Highest Hours of Activity

Mosquitoes are common pests that can be found all over the world. Different species of mosquitoes are active at different times of the day. Here are the top 4 common mosquitoes and their most active hours of the day.


The Aedes mosquitoes are most active during the daytime. Aedes is a genus of mosquitoes native to areas with standing water, such as marshes and swamps.

They are known for being vicious and painful biters, and their bites can be incredibly itchy. The two most significant species are Aedes albopictus (the Asian tiger mosquito) and Aedes sollicitans (the salt marsh mosquito).

These mosquitoes are most active outdoors during the early morning, from around five o’clock to seven o’clock. However, since temperature and weather affect the activity of these pests, they can also feed during sunset.


The Culex mosquitoes are most active at night. Culex is a genus of mosquitoes that includes hundreds of species, many of which are vectors for diseases like the West Nile virus and Japanese encephalitis.

These mosquitoes are most likely to bite humans indoors, making them a major pest in households. These hours are between 8 o’clock in the evening up to 6 o’clock in the morning.


The Anopheles mosquitoes are most active at dawn and dusk. Anopheles is a genus of mosquitoes that includes over 460 species.

These pests are vectors for diseases like malaria, filariasis, and the West Nile virus. They are most active during the hours of dawn and dusk when they can feed without being exposed to direct sunlight.

Zosterops japonicus

The Zosterops japonicus mosquito is most active during the day. Zosterops japonicus is a species of Old World white-eye that is found in East Asia.

This species of mosquito is known to be a vectors for the West Nile virus and Japanese encephalitis. They are most active during the daytime, from around eight o’clock in the morning until sunset.

Are Mosquitoes Active at Night?

Mosquitoes are attracted to light in the same way that other insects are. With this in mind, some mosquitoes can be active during the nighttime and are attracted to moonlight.

The moonlight affects the activity of different genera of mosquitoes. For instance, Culex species are more attracted to light during a full moon than they are during a new moon. On the other hand, Anopheles species are less active when there is a full moon.

Why Are Mosquitoes More Active at Night?

The sunlight fades and the air grows cooler. Fireflies begin to dance in the dusk, and creatures of the night begin to stir. Then, just as the stars come out, they appear: mosquitoes, flickering like tiny candles in the dark. But why are these pesky insects more active at night?

One reason may be that many of their natural predators, such as bats and dragonflies, are also nocturnal.

Additionally, mosquitoes are Cold-blooded insects, meaning that their body temperature changes with the ambient temperature. When it starts to get cooler at night, mosquitoes become more active as their bodies heat up. This gives them more energy to fly and bite.

Finally, some research suggests that mosquitoes may be more attracted to people at night because we emit more carbon dioxide then.

Carbon dioxide is a gas that we exhale with every breath. Mosquitoes use this gas to locate their prey, and so they may be more likely to bite us when we are exhaling more of it.

Why Should You Care When Mosquitoes are More Active?

Despite being small creatures, mosquitoes are known to carry and transmit a number of diseases. In fact, these pests are responsible for more human deaths than any other animal in the world.

As mentioned earlier, some species of mosquitoes can transmit malaria, the West Nile virus, and Japanese encephalitis.

Understanding their peak hours of activity can help you to avoid them and reduce your risk of being bitten.

For example, if you are planning to go outdoors during dawn or dusk, make sure to wear long sleeves and pants to cover your skin. You may also want to use an insect repellent containing DEET or picaridin.

More About Mosquitoes Activities

Mosquitoes seem to come out of nowhere and buzz around your head, but have you ever wondered what time of day they are most active?

These blood-sucking insects prefer the warm seasons so they come out during summer, spring and fall, and would enter a state of dormancy in the winter. They generally come out at dawn and dusk. Mosquitoes can also be active during the day in the early morning but would avoid going out at noontime and then resume their hunt for blood as the sun begins to set.

These pesky little insects can be a huge pain in the neck. So, if you are planning on being outdoors for any length of time, it is important to take precautions against these biting insects.

What Time of the Year Do Mosquitoes Come Out

Mosquitoes are most active during the spring, summer, and fall, although their season begins gradually in the spring and peaks during the summer before tapering off in the fall. When the weather is warm, mosquitoes come out in large numbers. As the temperature cools, they become less active and their populations dwindle.

Mosquitoes flourish in the summer and fall when temperatures reach 50°F or more. It is typically from April through October in the United States. They are most active when the temperature is high and there is a lot of moisture in the air. This is why mosquitoes are more common in the summer than in the winter.

Mosquitoes are most active during the summer months when the temperature is warm and the humidity is high because it provides them with ideal conditions for breeding. However, they can also be found throughout the spring and fall.

In some parts of the world, especially the ones with warmer climates, mosquitoes are active year-round. Insects are cold-blooded so when the weather is warm, mosquitoes become more active because their metabolism speeds up.

What Time of the Day Do Mosquitoes Come Out

In the early morning dawn, when the world is still asleep and the only sound is the birds singing.

The sun is just starting to peek over the horizon, painting the sky in a spectrum of oranges, pinks, and purples. And in the midst of this beautiful scene are mosquitoes, flying around in search of their next meal.

For many people, this is the time of day when they are most likely to get bitten by these pesky insects.

These little vampires prefer to come out in the early morning dawn when the temperature is just right for them.  Fortunately, they don’t stay out for long. As the sun rises higher in the sky, the mosquitoes begin to disappear, retreating to the coolness of shade and shadows.

They would then avoid noon time which is the hottest part of the day. The sun dehydrates them and may actually kill them so they seek shelter and go into hiding at midday.

They would hide beneath bushes and leaves on the ground, inside sheds, among yard clutter, or anywhere that’s dark and shady in the meantime.

Mosquitoes are attracted to certain chemicals that are emitted by the human body such as carbon dioxide, lactic acid, octanol, and human sweat which are difficult to avoid during hot sweltering summer days.

When people do activities and sweat, they release lactic acid which makes them more attractive to mosquitoes. It builds up in your muscles while you’re working hard.

Sweat contains lactic acid and is excreted through the skin. This scent becomes undoubtedly attractive to mosquitoes.

People are more active during the day and so are the mosquitoes. Humans breathe out carbon dioxide which is another mosquito attractant. It is odorless and colorless but mosquitoes can detect it.

CO2 is produced in greater quantities by people with a fast metabolic rate. Your metabolic rate will be higher if you just finished working out.

Pregnant women and those who are overweight have higher resting metabolic rates. On the other hand, children tend to have lower metabolic rates and produce less mosquito-attracting CO2 than adults.

What Time of the Night Do Mosquitoes Come Out

As the sun sets and dusk descends, these annoying little creatures of the night begin to stir. Shadows lengthen and deepen, and the sounds of the day give way to the song of crickets and the hoot of owls.

This is the time when mosquitoes come out. For these blood-sucking insects, nightfall is the signal to start their hunt for a meal.

They are most active from dusk till dawn when they can take advantage of the cooler temperatures and lack of sunlight.

This is another time of the day when they would come out to hunt and this is because the temperature starts to cool down again, making it more comfortable for them to be active.

They come out in the evening after the sun sets, and they’re active throughout the entire night and into the early morning right before the sun rises.

Even though not all mosquitoes carry diseases, they can all be a pain in the neck. To avoid being an easy food source for these blood-suckers, it is best to know when the time they are most active so you can avoid their main feeding times.

The mosquito season generally lasts from late spring until early fall. This covers the months when the weather is warmest and people are outdoors the most.

Mosquitoes are more likely to bite during the cooler hours of the day. Their feeding schedule would start early in the morning and they would take a break at noon until midday when the sun is up high in the sky. Their feeding frenzy would soon resume as the sun sets and the temperature begins to lower.

If you’re going to be outside during these times, make sure to wear long sleeves and pants, and use mosquito repellent.

Stay indoors as much as possible during dawn and dusk when mosquitoes are most active, and keep your windows and doors shut to prevent them from coming inside.

Try to keep your skin covered as much as possible so they can’t get to you. By taking these precautions, you can enjoy the outdoors without being a victim of these pesky insects. While you can do all of these to avoid being bitten by mosquitoes, sometimes they’re just unavoidable.

Final Thoughts

Mosquitoes are pesky insects that can be a nuisance both outdoors and indoors. They are most active during the early morning, from around five o’clock to seven o’clock, but they can also feed during sunset.

Mosquito activities are not generally ruled by what time of the day it is. Rather, they are affected by the weather, temperature, and what species they belong to.

There are many ways to prevent mosquito bites, such as using insect repellent, wearing long sleeves and pants, avoiding areas where mosquitoes are present, and using a mosquito net.

If you’re trying to keep mosquitoes away from your property, make sure to keep your grass cut short, remove any standing water from your property, and consider using mosquito repellent.
