Vector control has not identified or collected any Dengue infected Aedes mosquitoes. 

 Baldwin Park, Calif. (September 9, 2024) — The San Gabriel Valley Mosquito & Vector Control District (SGVMVCD/District) is working collaboratively with the Los Angeles County Department of Public Health to conduct additional surveillance, mosquito control, and educational outreach in the Baldwin Park community where a locally acquired case of Dengue has been confirmed. Testing of locally captured Aedes mosquitoes has not identified any Dengue infected mosquitoes. 

District staff have expanded surveillance by deploying additional traps and increased the frequency of testing to identify the presence of mosquito-transmitted diseases in local mosquito populations. Additionally, field staff are conducting door-to-door property inspections and mosquito treatments to reduce adult mosquito populations and mosquito breeding sources. 

“The District has acted as quickly as possible to enhance surveillance, mosquito education, and perform mosquito control in the area,” said District Manager Jason Farned. “The District will continue its surveillance and control efforts, including additional backpack and truck-mounted mosquito treatments to reduce adult mosquito populations and mosquito breeding sources.” 

The District has scheduled two truck-mounted treatment events scheduled for September 11th and September 12th, between 12 AM to 5 AM. Depending on surveillance trap results, additional truck-mounted treatments will be considered. Residents may visit www.publichealthmosquito.org to find out more information regarding the treatment area and the products being used. 

“Representatives will be available Monday through Thursday, 7AM to 5PM to answer any questions or concerns relating to mosquito activity,” said Director of Communications Anais Medina Diaz. “Residents are encouraged to visit the District’s website for the latest information and resources on how to reduce mosquito breeding on their property and how to prevent mosquito bites.” 

Mosquito control is a shared responsibility. The District urges residents to take an active role in reducing the threat of Dengue in their community by taking the following actions to stay healthy and bite-free: 

• Tip out stagnant water around the home weekly; 
• Toss unused containers that can hold stagnant water; and 
• Protect against bites by using insect repellent containing any one of the following CDC-recommended ingredients: Picaridin, DEET, Oil of Lemon Eucalyptus (or PMD), or IR3535. 

If residents suspect they are experiencing any dengue-related symptoms, they are encouraged to reach out to their primary health care provider.

About SGVMVCD SGVMVCD is one of five vector control districts in Los Angeles County. Year-round, the agency monitors stagnant water sources, such as gutters, storm drains, channels and non-functional swimming pools. The agency also routinely monitors populations of adult mosquitoes using traps and tests groups of adult female mosquitoes for the presence of WNV and other mosquito-borne diseases. In addition, the agency submits samples from dead birds, such as crows, for testing, which can provide insight into the spread of WNV.
