According to Dan Markowski from the American Mosquito Control Association (AMCA), the Midwest, West, and South-Central United States are predicted to see a surge in mosquito activity in the spring and early summer of 2026. This rise is attributed to warmer temperatures and increased rainfall, creating ideal breeding conditions. The South-Central U.S. is particularly at risk due to a mild winter followed by a wet spring, leading to high mosquito numbers through late May and early June. Similarly, California and other western states are experiencing early mosquito emergence because of warm, wet conditions. The Midwest's unusually wet spring is also expected to drive large populations of spring-breeding mosquitoes, with significant activity in May and June. This increase raises concerns about the potential spread of diseases like West Nile virus and Zika virus.
