Pilot Program Launch in Localized Areas of Sunland-Tujunga 

Los Angeles, CA  (October 12, 2023) - A new pilot program is underway in your neighborhood called the Sterile Insect Technique (SIT). SIT is an environmentally safe and chemical-free approach for the control of certain insect pests. The Greater Los Angeles County Vector Control District (GLACVCD) is exploring the use of (SIT) to control invasive Aedes aegypti mosquitoes and is evaluating the efficacy of this innovative technology.

At this point in the program, the District will release locally acquired and reared, non-biting, male mosquitoes from the area on Thursday, October 12, 2023, within the specified zones of Alpine Village and Sevenhills neighborhoods in Sunland-Tujunga. Once released, the District will set traps in these neighborhoods to recollect and recapture the mosquitoes. This will help determine the size of the local mosquito population, how far these mosquitoes can fly, and ensure the efficiency and success of the pilot program in reducing the local population of invasive Aedes aegypti mosquitoes.
