This month, we celebrated the District’s 35th Anniversary with an Open House Luncheon for District’s partners. We were joined by representatives from the offices of State Senator Susan Rubio, Assemblymember Blanca Rubio, Assemblymember Lisa Calderon, Assemblymember Mike Fong, and Los Angeles County Supervisor Hilda Solis. Additionally, city officials, water district representatives, and other local agency partners who have collaborated with us in the past were in attendance. 

A part of our open house included an interactive District tour, where we showed guests aspects of what we do at the District and how each department contributes to mosquito control efforts.

We are grateful to all of those who joined us and to our staff who helped put together a marvelous anniversary event.

Mosquito Activity Overview

Our District’s surveillance team reports mosquito trap activity. The purpose of trapping is to monitor mosquito presence and risk of mosquito-borne disease.

This month’s report shows that 2024 trapping (red) is recording high abundance numbers compared to past years.

This means that you may see more mosquitoes in your community this month due to consistent 70 degree daytime temperatures. So it’s time to mosquito-proof your home and stock up on mosquito repellent sooner rather than later.

May contain: animal, insect, invertebrate, and mosquito
We continue to maintain essential vector surveillance including mosquito traps for disease testing, providing weekly data to the District, and maintaining mosquito fish.
