Why We Are Treating
We are conducting mosquito treatments to stop the invasive Aedes aegypti mosquito. This type of mosquito is aggressive, bites multiple times, and bites during the day. These spray treatments are important to protect public health because this mosquito can spread diseases like Zika, dengue, yellow fever, and chikungunya. These are diseases that are currently not in our community.
If this mosquito becomes common in Santa Clara County, it will change our quality of life.
About the Treatments
The treatments target places with standing water where mosquitoes can lay eggs. These are known as Wide Area Larvicide Spraying treatments. The spraying helps us reach places with standing water that are hard to reach.
The treatments happen in neighborhoods where this mosquito has been found. To see a list of affected neighborhoods, visit our Aedes Aegypti Detection Timeline page.
What We Are Doing
We are working hard to get rid of the mosquitoes in the affected communities by:
- Trapping adult mosquitoes in and around the affected neighborhoods to monitor the infestation.
- Talking to residents and community members to get rid of standing water around their yards where mosquitoes can lay their eggs.
- Inspecting yards for mosquitoes and treating them by hand as necessary.
- If needed, we will also take stronger steps like the wide area larvicide spraying treatments to treat larger areas quickly.
