Mosquito Control Treatments Planned in Monterey Park
The San Gabriel Valley Mosquito and Vector Control District is conducting truck-mounted mosquito control treatments in Monterey Park this Wednesday and Thursday between midnight and 5 a.m. to reduce mosquito populations and lower the risk of disease transmission. The operations target adult mosquitoes in an area bounded by West Floral Drive and the Pomona (60) Freeway, east of Vancouver Avenue and west of Collegian Avenue.
Where and when are the mosquito treatments happening?
According to district officials, the treatments are scheduled for Wednesday and Thursday this week. Work will occur during the overnight hours from midnight to 5 a.m.

The specific treatment zone is bounded by the Pomona (60) Freeway to the south and West Floral Drive to the north. The boundaries extend east of Vancouver Avenue and west of Collegian Avenue.
What chemicals are being used and are they safe?
SGV Mosquito specialists are applying Aquaduet, which contains Sumithrin and Prallethrin. District officials stated these applications target adult mosquito populations that pose a significant public health risk.
Officials clarified that because the material is suspended in water, the application will not harm the finishes on homes or cars.
What happens if the weather is bad?
Treatments could be delayed or postponed if operational issues arise or if weather conditions are unfavorable. District officials said any postponed applications would be rescheduled for the following week.
How can residents help reduce mosquito populations?
Officials urged residents to eliminate standing water in containers such as discarded tires, clogged gutters, birdbaths, and buckets. Proper maintenance of ponds, spas, and swimming pools is also recommended.
To avoid bites, the district encouraged the use of insect repellent and wearing long pants and sleeves when outdoors. Residents in the treatment area will receive notifications via social media, Nextdoor, local news outlets, and posted notices.
