District Communication

Mosquito season is in full swing this summer, with populations rising steadily as expected during the warmer months. Our District’s dedicated Vector Control Specialists are actively working in local neighborhoods, carrying out daily inspections and treatments to help reduce mosquito breeding and protect public health.

If you notice standing water or an increase in mosquito activity, don’t hesitate to submit a tip. Your reports help us respond quickly and keep the community safer.

Controlling mosquito populations is a shared responsibility. Help do your part by remembering to tip, toss, and protect:

  • Tip out any stagnant water
  • Toss unused containers that can collect water
  • Protect yourself with mosquito repellent

Our District is currently juggling multiple priorities across the San Gabriel Valley. While the Eaton burn response remains a top focus, we’re also actively monitoring public spaces for mosquito breeding as warming temperatures, especially hotter nights, as they create ideal weather conditions for mosquito activity.

Additionally, our Surveillance team regularly sets traps throughout the San Gabriel Valley to monitor mosquito activity and detect mosquito-borne diseases. We've also increased efforts in the Eaton burn area, using data from these traps to guide targeted mosquito control actions.

EcoHealth Highlights

Summer kicked off with a buzz at the Glendora Library’s Discovery Zone event. Families gathered at the District’s EcoHealth booth, eager to learn about mosquitoes and how to prevent the spread of mosquito-borne diseases.

The EcoHealth booth featured a variety of hands-on activities, including a close-up look at the mosquito life cycle under a microscope and our interactive Larva Lab (a fun sorting game that let visitors identify different mosquito larvae). These engaging experiences sparked curiosity and helped create a fun, educational environment for families of all ages.
