Mosquitos need temperatures above 50°F to be comfortable; they thrive in hot weather. As temperatures rise in the summer, the mosquito population is at its peak. Because they are cold-blooded pests, they hibernate in the winter. That’s when the adult females of some species find holes to hide in until the weather gets warmer. Other species lay their eggs in freezing water and die. The mosquito season doesn’t end until the temperature drops below freezing. The three factors that most influence the beginning and end of the mosquito season are:
- Geographical Location
- Seasonal Temperatures
- Timing of Rainfall
The mosquito population is more prevalent in the South than it is in the North. The temperatures in the southern states stay warmer for so much longer that mosquitos can stay alive for extended periods of time. In addition, the Southern seasons become warmer more quickly, which is conducive to the health and liveliness of mosquitos.
Another major influence on the beginning and end of mosquito season is rain because the eggs laid by the female mosquitoes need at least an inch of water surrounding them in order for them to produce larvae and develop into full-grown mosquitoes.
