District Communication

The San Gabriel Valley Mosquito & Vector Control District is proud to launch a new sustainable initiative: SGV Mosquito Match! This innovative program uses Sterile Insect Technique to help control populations of invasive Aedes mosquitoes (commonly known as ankle biters).
Aedes mosquitoes are aggressive daytime biters and are capable of transmitting serious diseases such as Zika, Dengue, and Yellow Fever. To combat this threat, our method involves releasing sterile male Aedes mosquitoes that carry Wolbachia (a naturally occurring bacterium found in more than 60% of insect species), which cannot produce offspring when they mate with wild female mosquitoes.
When they MATCH their eggs don’t HATCH:

Mosquito Seasonal Activity Returns to San Gabriel Valley

The District has confirmed its first West Nile virus (WNV) activity of the season within its service area. WNV is a yearly threat, consistently detected in both infected animals and, occasionally, in humans each year.
With this being the first detection of the season, the District continues its proactive efforts to monitor and control the spread of the disease. Residents are urged to stay alert and help reduce mosquito breeding by practicing the Tip, Toss, and Protect method.
