What happens to mosquitoes in the winter? After a warm summer full of bug bites, you might think, “When will mosquitoes leave?”
Mosquitoes are found everywhere except Antarctica and Iceland, so they’ll be back when it gets warm again. They’re never really gone for good.
Mosquitoes don’t just vanish when it gets cold. How do they make it through the winter?
Here’s all you need to know about mosquitoes in the cold months and if there’s a way to enjoy spring without the worry of itchy bites.
The best nest rule
Once, in a green forest, there were 3 sibling birds. Each one wanted to make the best nest.
In a green forest, three birds sought the ideal nest. Chirpy chose a high, cold branch; Pecky, a damp ground spot.
Flappy wisely picked a sheltered, sunlit middle branch. The leaves kept off the rain, and it was safe from animals on the ground.
The sun shone through just enough to keep the nest warm but not hot.
It shows how important it is to find the just right place.
Like these birds, mosquitoes like a certain temperature: 80 degrees. Below 60 degrees, they become slow, and around 50 degrees, they either sleep or die.
Mosquitoes have a long nap in the winter
When the weather turns cold, many species of mosquitoes die off, leaving only eggs that lie on the ground like seeds, waiting for warmth and spring rains to hatch and produce a new generation.
However, some species of mosquitoes survive cold weather by hibernating. Mosquitoes that belong to the genera Anopheles, Culex and Culiseta hibernate, and so do some other less common types in the United States.
It’s hard to believe that these fragile-looking creatures can survive freezing temperatures. They take a position called the “hibernation squat,” bending their legs and tucking their body close to the surface they sit on.
Easy-to-use mosquito-proof bracelets
To fight off mosquitoes, handy bracelets that keep them away are a smart choice.
They release a smell or thing that mosquitoes don’t like, making a safe zone around the person wearing it.
This is great for those who spend lots of time outside or in areas with lots of mosquitoes.
Different from old ways of removing mosquito places, these bracelets give direct protection without needing sprays or gadgets.
Using these bracelets together with other ways to control mosquitoes can give a stronger defense, making sure you’re comfortable and safe when it’s warm.

FAQs: Mosquito cold weather
As temperatures drop, these tiny pests undergo significant changes in their behavior and survival strategies. Let’s explore some common questions about mosquitoes and cold weather.
Do mosquitoes die in the winter?
Mosquitoes don’t all die in winter. Cold weather can still reduce their overall numbers, as some species go into diapause or die off due to low temperatures.
What temperature kills mosquitoes?
Cold weather can cause some mosquitoes to become inactive and eventually die, especially when temperatures drop below 50°F. However, not all mosquitoes die in cold weather as some species have adapted to survive in colder climates
Do mosquitoes hibernate?
Mosquitoes have various ways to get through winter. Some adult female mosquitoes put eggs in safe places like tree holes or water that will freeze.
This keeps the eggs safe until it’s warm enough to hatch. Other females use plant sugars to build up fat and sleep through winter, waiting to lay eggs in spring.
When it gets to about 50°f or lower, mosquitoes go into a state called diapause.
This is like a paused state, helping them survive the tough winter, and keeping the eggs from hatching until then.
Do both female and male mosquitoes hibernate?
No. Only female mosquitoes go into a state similar to hibernation. Male mosquitoes have a much shorter lifespan, typically living only about a week, and do not survive through the winter.
Female mosquitoes, on the other hand, can enter a state called diapause when temperatures drop, slowing down their biological processes to survive the colder months.
Do mosquitoes transmit diseases when hibernating?
Mosquitoes can transmit diseases when they are active and biting humans.
However, when the weather turns cold, many species of mosquitoes die off, leaving only eggs that lie on the ground like seeds, waiting for warmth and spring rains to hatch and produce a new generation.
During hibernation, mosquitoes become inactive and do not bite humans.
Do all mosquito species hibernate during winter?
Not all mosquito species hibernate. The behavior varies among species, with some entering diapause while others lay eggs that survive the winter or migrate to warmer areas.
At what temperature do mosquitoes become inactive?
Mosquitoes generally become inactive at temperatures around or below 50°F. They are cold-blooded and their activity levels decrease significantly as the temperature drops.
Can mosquito eggs survive the winter?
Yes, mosquito eggs can survive the winter. Females lay eggs in places like moist soil or water that will freeze, allowing the eggs to hibernate and hatch when conditions become favorable.
