2021 Mosquito Forecast
For many Americans, mosquitoes are a year-round disturbance. These tiny, blood-thirsty insects will attach anywhere from head-to-toe, particularly during warmer months. They also carry diseases that can cause severe symptoms like fevers, diarrhea, vomiting, and even death.
Diseases carried by mosquitoes kill more people than any other living species on Earth. According to Gates Notes, more than 700,000 people worldwide die in any given year as a result of the diseases these bugs carry.
Where Do Mosquitoes Live?
Part of the reason mosquitoes are so dangerous is that they thrive is warm temperatures. Their preferred temperature is anything above 70 degrees Fahrenheit, which means they can exist for some length on every continent in the world except for Antarctica. They primarily like to live in places that:
Are warm throughout
Have moist, tropical climates
Have standing water
In these tropical climates, mosquitoes can live and reproduce all year. If the temperature drops below 50 degrees Fahrenheit for an extended period of time, the mosquitoes become dormant until the cold spell is over or they die.
The Bottom Line
The weather models showed how likely it was that precipitation totals and temperatures would be higher or lower than average during each month of the year. We took these weather models and compared them to where mosquitoes are present and are becoming more populous in each region of the country. Once we distilled, cross-referenced, and computed the data, we came to reasonable conclusions based on logic and general mosquito trends over time.
