What Temperature Is Too Hot for Mosquitoes

Mosquitos are a common pest in all parts of the world. In fact, there are about 200 different mosquito species in the United States alone.

It’s well-known that mosquitos tend to thrive in warm climates, but how warm is too warm? The short answer to that question is that the average mosquito cannot live in temperatures hotter than 104 degrees Fahrenheit; However, the answer may vary depending on the specific species of mosquito.

Common Mosquito Species in the United States

There are more than 200 different mosquito species in the United States, but what they all have in common is that they can all carry diseases and are dangerous.

Some of the most common mosquito species in the United States include Aedes aegypti, Culex, and the Anopheles Freeborni. 

Aedes Aegypti

The Aedes Aegypti mosquito lives in the US and prefers tropical or subtropical climates. They are one of the most common carriers of Zika, Dengue, and Chikungunya diseases.

They live near and around many populated areas; therefore, they are among one the most dangerous species of mosquitos as they have the opportunity to spread disease.

Since the Aedes Aegypti mosquito species prefer warmer climates, they can survive in climates up to the maximum heat index for mosquitos which is 104 degrees Fahrenheit. 


The Culex mosquito is another common species found in the United States. This species bites both humans and animals and is known for feasting at night, whereas the Aedes species feed primarily during the day and at dusk.

The Culex mosquito is the most dangerous species of mosquito, mainly because it transmits the West Nile Virus, which has killed some of the largest populations in history resulting from an insect bite. This type of mosquito may be able to live in temperatures up to 104 degrees Fahrenheit but do prefer cooler temperatures. 

Anopheles Freeborni

The Anopheles Freeborni mosquito is common in the western part of the United States. It is sometimes called the “western malaria mosquito” due to its notorious trait of carrying and transmitting Malaria.

You will find these mosquitos in cool, damp areas such as ponds and streams, yet they typically thrive in a dry, hot climate. The Anopheles Freeborni mosquito can also live in maximum temperatures of 104 degrees Fahrenheit and often take the heat better than the other species mentioned above.

Staying Safe from Diseases Transmitted by Mosquitos
