Mosquito Control Efforts Intensify in Minnesota

Jun 6, 2024

—

As spring unfolds, the Metropolitan Mosquito Control District (MMCD) ramps up its efforts to combat rising mosquito populations amid elevated rainfall.

Monitoring and Surveillance

Utilizing a comprehensive approach, the MMCD closely monitors mosquito populations weekly from mid-May through September. Various traps are strategically placed across the district to capture mosquitoes and black flies for identification in the lab.

Rainfall Impact

Recent data indicates heightened mosquito activity attributed to the third-wettest May in the last decade, leading to increased hatching of mosquito eggs with each subsequent rainfall.

Current Situation

The initial weeks of MMCD surveillance in 2024 have revealed above-average mosquito activity, fueled by continuous rain and favorable breeding conditions. Black flies, particularly prevalent near rivers and streams, persist despite ongoing treatments.

Historical Comparison

Contrastingly, June 2023 witnessed minimal mosquito breeding due to warm and dry weather conditions, highlighting the significant influence of climate factors on insect populations.

As Minnesota braces for the peak of mosquito season, vigilance and proactive measures remain crucial in mitigating potential nuisances and health risks posed by these pests.
