Mosquitoes in Fresno, California: A Persistent Public Health Challenge

As summer temperatures soar in Fresno, California, residents face an annual resurgence of mosquitoes, bringing with them the risk of mosquito-borne diseases. The primary culprits are the Aedes aegypti and Culex quinquefasciatus species, known vectors for diseases such as West Nile virus (WNV) and St. Louis encephalitis virus (SLEV).

The Threat of Mosquito-Borne Diseases

In 2024, Fresno County reported three asymptomatic human infections of WNV, identified through routine blood donor testing. Additionally, 56 mosquito samples tested positive for WNV that year. Tragically, the county confirmed its first human death due to WNV in September 2024 . SLEV was also detected in the county in 2024, marking a concerning development in the region’s public health landscape .

Innovative Control Measures: The Debug Fresno Project

To combat the mosquito menace, Fresno County has implemented innovative control strategies. One notable initiative is the Debug Fresno project, a collaboration between Verily (an Alphabet subsidiary), MosquitoMate, and the Consolidated Mosquito Abatement District. This project involves releasing sterile male Aedes aegypti mosquitoes infected with the Wolbachia bacterium. When these males mate with wild females, the resulting eggs do not hatch, leading to a decline in the mosquito population. Over three seasons, the project achieved up to a 95% reduction in biting female Aedes aegypti mosquitoes in targeted areas .

Preventive Measures for Residents

Residents can take proactive steps to reduce mosquito breeding grounds and protect themselves:

• Eliminate Standing Water: Regularly empty containers like flowerpots, birdbaths, and gutters where water can accumulate.

• Use Insect Repellents: Apply EPA-registered repellents containing DEET, picaridin, oil of lemon eucalyptus, or IR3535, especially during dawn and dusk when mosquitoes are most active.

• Install and Maintain Screens: Ensure windows and doors have tight-fitting screens without holes to prevent mosquitoes from entering homes.

• Wear Protective Clothing: When outdoors, wear long-sleeved shirts and long pants to minimize skin exposure.

Community Resources

The Fresno Mosquito and Vector Control District offers free yard inspections to help residents identify and eliminate mosquito breeding sites. They also provide guidance on preventive measures and can be contacted for assistance with mosquito-related concerns .

Conclusion

Mosquitoes remain a significant public health concern in Fresno, California. Through community engagement, innovative control measures like the Debug Fresno project, and individual preventive actions, residents can work together to reduce the impact of mosquito-borne diseases in the region.
