Are Mosquitoes Seasonal? | San Joaquin Pest ControlMosquitos are one of the most annoying of all pest nuisances around. They swarm around and ruin your outdoor fun, resulting in insanely itchy whelps that seem to linger on your skin for days. It makes outdoor activities much less appealing. You may be wondering if there is any time of year when you can relax and get a brief respite from the threat of mosquitos. So, are mosquitoes seasonal?

The short answer is yes. Mosquitoes are much more prevalent in warmer times of the year than cold. In fact, when the temperature drops below 50 degrees Fahrenheit consistently, mosquitoes go into hibernation for the winter. They are cold-blooded creatures and they can’t regulate body heat – which means their temperature is basically the same as that of their surroundings. So depending on the climate where you live, you may get a break from mosquito invasions for a few months or more.

As overall temperatures increase around the globe, “mosquito season” seems to be extending. Mosquitoes are emerging earlier and earlier as warm weather arrives sooner, and they also are staying around longer since the first frost has been delayed. This frost typically kills off the mosquitoes or sends them into hibernation, but in many areas this is happening very late into the year. What this means is that the threat of mosquitoes is very real for a large portion of the year in many areas of the United States. Areas of Texas and Florida may actually see their mosquito seasons begin as early as February.

There are other weather conditions that may lead to a more severe mosquito season some years than in others. For instance, in times of drought, street drains, ponds, lakes, and other water sources wither up and become stagnant. This provides the perfect setting for mosquitoes to lay their eggs. To add to the issue, rainfall after a drought causes mosquito eggs to hatch and the larvae to emerge. The fish and other predators that normally would kill these larvae may have died off from the drought, meaning the number of surviving larvae are not limited as they normally would be.

Now that you know when to expect mosquito season, you can take the steps to install preventative measures. Speak with a local pest control company in your area to discuss common approaches that would allow you and your family members to be able to enjoy a spring and summer spent outdoors, free of the constant threat of mosquitoes.
