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

West Covina, Calif. (October 21, 2023) — The San Gabriel Valley Mosquito & Vector Control District (SGVMVCD/District) is working collaboratively with the Pasadena Public Health Department to conduct additional surveillance, mosquito control, and educational outreach in the Pasadena 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 increasing the frequency of testing to identify the presence of mosquito-transmitted diseases in local mosquito populations. Additionally, field staff have conducted property inspections to reduce mosquito breeding sources and performed mosquito control treatments in the area.

“The District has acted as quickly as possible to enhance surveillance and perform mosquito control in the area,” said District Manager Jason Farned. “The District will continue its surveillance and control efforts in the coming weeks, including additional backpack and truck mounted mosquito treatments.”

District representatives will be conducting property inspections in the area beginning this weekend. Additional representatives will be available on Saturday, October 21st from 7:00am to 7:00pm  to answer any questions or concerns relating to mosquito activity.

Mosquito control is a shared responsibility. While Dengue is not actively transmitted by local mosquitoes, 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.
