Mosquito Spraying Planned In San Gabriel Valley

MONTEREY PARK, CA — Mosquito control trucks will treat parts of Monterey Park and West Puente Valley this week as officials work to reduce mosquito populations and the risk of mosquito-borne disease.

The San Gabriel Valley Mosquito and Vector Control District will conduct the treatments Wednesday and Thursday between midnight and 5 a.m.

The district said the treatments could be delayed or postponed if weather conditions are unfavorable or operational issues arise. Any postponed treatments are expected to take place later in the same week.

In Monterey Park, the treatment area is between West Floral Drive and the 60 Freeway, east of Vancouver Avenue and west of Collegian Avenue.

In West Puente Valley, treatments are planned between Sunset Avenue and North Hacienda Boulevard, north of Amar Road and south of West Francisquito Avenue.

Crews will use ultra-low-volume applications of AquaDuet to target adult mosquitoes. The product contains sumithrin and prallethrin, active ingredients formulated to mimic properties found in chrysanthemum flowers, according to the district.

Because the material is suspended in water, the district said the treatment will not damage finishes on vehicles or homes.

Residents in the affected areas will be notified through postings, social media, Nextdoor and news media. Updates are also available through the district's website.

Officials are urging residents to help reduce mosquito populations by eliminating standing water from rain gutters, buckets, discarded tires, rain barrels and other containers. Pools, spas and ponds should be properly maintained, while water in pet dishes, birdbaths and other small containers should be changed weekly.

Residents can also reduce their risk of mosquito bites by using repellent containing EPA-approved active ingredients such as DEET, picaridin, IR3535 or oil of lemon eucalyptus and by wearing light-colored long sleeves and pants outdoors.
