Which environmental factor can help reduce mosquito populations?

Drier weather conditions can significantly impact mosquito populations because mosquitoes thrive in environments with ample moisture and stagnant water, which serve as breeding grounds. When weather conditions are drier, there is less standing water available for mosquitoes to lay their eggs, thereby reducing their reproductive opportunities.

Additionally, dry weather can lead to decreased survival rates for larvae and adult mosquitoes, as they depend on humid environments for hydration and reproduction. Consequently, this combination of reduced breeding sites and higher mortality rates can effectively lower mosquito populations, making drier weather a natural method of control for these pests.

Other factors, such as increased humidity or more standing water, actually favor mosquito survival and reproduction, while fluctuating temperatures can create unstable conditions that do not consistently hinder their populations in the same way.
