California is releasing 500,000 mosquitoes. Here's why that's a good thing
Reported byGoodGoodGood ↗·Sourced by Goodlede
The San Gabriel Valley Mosquito and Vector Control District will release more than 480,000 sterile male mosquitoes weekly between now and October 2026 to combat invasive yellow fever mosquitoes that carry dengue and Zika; the sterile insect technique (SIT) has reduced invasive mosquito populations by up to 90% globally and is now deployed against Aedes aegypti in Southern California.
While this program is species-specific and harmless to other wildlife, longer-term success depends on sustained releases and monitoring.
