Mosquito Control Operation in Pasadena: Protecting Against West Nile Virus

PASADENA, Calif. — In an effort to mitigate the threat of mosquito-borne diseases like West Nile virus, insect-control authorities in the San Gabriel Valley will conduct a two-day mosquito control operation on Tuesday and Wednesday in the Pasadena region.

The operation is scheduled to take place from midnight to 5 a.m. on both days, covering the area bounded by the Foothill (210) Freeway and Arroyo Seco to the north, situated between Everts and Hammond streets. The San Gabriel Valley Mosquito and Vector Control District will oversee these efforts.

The primary approach involves using a specially equipped truck to disperse “ultra-low-volume adulticide” and “low-volume larvicide” applications, which target mosquitoes at various stages of development. This tactic aims to reduce the mosquito population and minimize the risk of mosquito-borne diseases, as per the district’s statement.

Tristan Hallum, Director of Scientific Programs at SGVMVCD, stated, “Our surveillance data has indicated mosquito populations that are four times higher than our five-year average. The heightened mosquito presence heightens the potential for disease transmission. The treatment will contribute significantly to diminishing mosquito populations and lowering the risk of mosquito-borne illnesses.”

The district advises residents to take measures to manage mosquito populations, including:

  1. Removing stagnant water from clogged rain gutters, rain barrels, discarded tires, buckets, and other containers that hold water for more than a week.
  2. Ensuring proper maintenance of swimming pools, spas, and ponds.
  3. Regularly changing the water in pet dishes, birdbaths, and other small containers.
  4. Reporting neglected swimming pools to the vector control district.

Additionally, the district encourages residents to use mosquito repellent on exposed skin when going outdoors and to wear loose-fitting, light-colored, long-sleeved shirts and long pants to minimize mosquito exposure.
