Mosquitoes in winter? Scientists say pests will be a year-long problem thanks to climate change

By Study Finds - October 2, 2021

GAINESVILLE, Fla. — Mosquitoes are one of the few unpleasant parts of summer. As the temperature rises, these disease-carrying pests become a common sight, especially around standing water. Thankfully, these tiny nuisances don’t follow us into the winter, right? Wrong. According to researchers in Florida, climate change will likely keep mosquitoes active even in the colder months of the year.


A team from the University of Florida adds, in places seeing the greatest effects of climate change, mosquito activity could soon become a year-round problem.

“In tropical regions, mosquitoes are active all year, but that isn’t the case for the rest of the world. Outside of the tropics, winter temperatures cause mosquitoes to go into a kind of hibernation called diapause. We call these mosquitoes ‘cold bounded’ because their activity is limited by these lower temperatures,” says Brett Scheffers, assistant professor in the UF/IFAS wildlife ecology and conservation department, in a university release.

“However, with climate change, we expect summers to get longer and winters to become shorter and warmer. What will that mean for those cold-bounded mosquitoes? How will they respond?”
