Mosquito Season by State

When does mosquito season start?

Spring is almost here and so are the mosquitoes! When you will start seeing mosquitoes depends on where you live. Mosquitoes become active as soon as temperatures are consistently above 50 degrees.  

Mosquito season can start as early as February in some areas with warmer climates, and as late as May in cooler climates. People who live in warmer, more humid climates like the southeastern region of the United States will start seeing mosquito activity around the beginning of March.  

When temperatures begin to rise, mosquitoes will do one of two things: come out of hiding or begin their lifecycle.  

Female mosquitoes that hibernated over the winter will come out of their dormant state and begin coming out of their hiding places. Alternatively, eggs that were laid during the winter will quickly begin moving through their lifecycle. During this time, the eggs will develop from larvae to pupae to adults. Some species of mosquitoes can go through their entire lifecycle in just 7-10 days!  

Not only are mosquitoes a nuisance, but they are also a threat to your family and your pets! Below are tips on how to prevent mosquitoes around your home.  

When does mosquito season end?

When temperatures dip below 50 degrees Fahrenheit, mosquito activity plummets. In the northern parts of the United States like Maine, Minnesota, Michigan, and Washington, mosquito season usually ends in September. Parts of Texas and Florida have a mosquito season that virtually lasts the entire year.

When mosquito activity is high, you are more likely to get a mosquito bite. More than just an annoyance, mosquito bites can also transmit diseases like yellow fever, Dengue, West Nile virus, and Zika virus.
