As summer temperatures continue to rise, so does the threat of West Nile virus. You can help lower the risk of the virus spreading through infected mosquitoes by dumping and draining standing water around your home at least once a week. The County of Santa Clara Vector Control District has created a “Skeeter Meter” to help people know the current risks. See the risk levels at https://vector.santaclaracounty.gov/mosquitoes/west-nile-virus-risk-level.

As the weather continues to warm up for the summer, West Nile virus risk is also on the rise. Stay ahead of the risk by checking our Skeeter Meter webpage for real-time West Nile virus risk updates in our county. We’ll keep you posted as new data comes in and risk levels change. Check the current risk level by visiting http://vector.santaclaracounty.gov/SkeeterMeter 🦟

Help protect your loved ones: Dump and drain standing water around your home at least once a week to reduce mosquitoes and lower the West Nile virus risk around you.
