You’re not nuts: The mosquitoes in Phoenix have gone bananas this year - Phoenix New Times

The mosquito population in Phoenix has experienced a significant uptick, with complaints to the Maricopa County Vector Control Division rising by 400% compared to last year. From approximately 1,500 complaints in 2024, the number has soared to around 6,000 in 2025, driven largely by favorable weather conditions, including heavy rainfall at the end of September and warm temperatures in October. These conditions have resulted in unusual mosquito population spikes across the region, not just in typical hotspots. While many mosquitoes in the area, particularly floodwater mosquitoes, are merely nuisances and less likely to carry diseases, certain species like the Aedes aegypti and Culex mosquitos, which are linked to diseases such as West Nile Virus and St. Louis Encephalitis, have also seen increased activity. As cooler temperatures approach, experts believe mosquito populations will decline, but upcoming rainstorms could complicate the situation by sustaining breeding environments. Residents are advised to manage standing water around their homes to help curb mosquito breeding.
