Summary
Council proclaimed June 15–22 as National Mosquito Control Awareness Week and heard a briefing from the San Gabriel Valley Mosquito and Vector Control District on rising mosquito activity and recent locally transmitted dengue cases in the region.
On June 17 the Monrovia City Council proclaimed June 15–22, 2025, as National Mosquito Control Awareness Week and received a presentation from Pablo Cabrera, communications specialist with the San Gabriel Valley Mosquito and Vector Control District.
Cabrera told the council that San Gabriel Valley communities accounted for 41% of Los Angeles County’s West Nile virus human cases in 2021 and noted an increase in locally transmitted dengue activity the previous year (11 locally transmitted cases in the San Gabriel Valley out of 18 statewide). He said mosquito populations have been increasing in recent weeks as temperatures rise and urged residents to “tip and toss” standing water, use EPA‑registered repellents and report potential mosquito sources on the district’s website. He said the district is funded through property taxes and provides services at no additional cost to residents.
The council accepted a “mosquito bite prevention” kit from the district for upcoming community events and thanked the district for its outreach; staff noted funding needs remain for vector work in areas affected by the Eaton Canyon Fire and said they are pursuing funds to support those treatments.
The district also described a free microchip clinic and a pet emergency preparedness seminar being offered by Pasadena Humane; those items were presented earlier in the meeting.
