Why you should be glad 500K mosquitoes are being released in San Gabriel Valley
LAist • • health
Key Points:
- The San Gabriel Valley Mosquito and Vector Control District is releasing over 480,000 sterile male mosquitoes carrying Wolbachia bacteria to reduce the invasive Aedes aegypti mosquito population, which is a primary carrier of dengue.
- These sterile males cannot produce offspring with wild females, aiming to decrease the mosquito population over time; male mosquitoes do not bite, so residents will not experience increased bites despite seeing more mosquitoes.
- The release is focused on the Basset area, a hotspot for Aedes aegypti activity, over a 25-acre zone, with mosquitoes being released weekly from now through October to coincide with peak mosquito season.
- This method has been used successfully in other Southern California regions and targets the mosquito's limited flight range to contain the population control efforts locally.
- The extended release period aims to increase mating opportunities between sterile males and wild females, potentially reducing future mosquito generations and lowering biting incidents for residents.
