Mosquito season is beginning to ramp up as the weather warms up, with increased activity expected in several regions. Mosquitoes thrive in warm, humid environments, and their populations are expected to increase as temperatures rise. This seasonal change may raise concerns about mosquito-borne diseases such as West Nile virus and Zika. According to experts, mosquito season usually starts in the spring and lasts throughout the summer. Recent rains have created standing water, which serves as a breeding ground for these insects, exacerbating the problem.
