Additional West Nile virus activity has been detected in unincorporated Sonoma County just outside Rohnert Park.

The Marin/Sonoma Mosquito and Vector Control District announced that mosquitoes trapped in the vicinity of Millbrae and Langner avenues have tested positive for WNV.

This area, according to the district, has seen virus activity in past years. Adult mosquito control operations were conducted early on Aug. 14 to reduce the adult mosquito populations and break the transmission cycle. Additional surveillance and trapping will be conducted in the area to assess the mosquito populations and virus activity.

Residents are urged to report mosquito problems in their areas and to reduce mosquito production sites in their yards by removing standing water on a regular basis.  

Most importantly, residents should use personal protection measures against mosquito bites. Wearing long sleeved shirts, long pants and applying an effective repellent to exposed skin will help reduce the risk of WNV transmission from an infected mosquito.

To date, 12 dead birds and two mosquito samples have tested positive for WNV in Sonoma County, according to the district.

 

The district has provided simple ways to help reduce exposure to mosquitoes and lessen the risk of WNV:

• Eliminate standing water in rain barrels, old tires, buckets, kiddie pools or any other item that can hold water for more than 72-96 hours. 

 

• Check septic tank lids to ensure a tight seal and repair any visible cracks.

 

• Screen septic tank vent pipes using a fine mesh screen.

• Report mosquito problems, neglected swimming pools, or any area that could be producing mosquitoes at www.msmosquito.com or (800) 231-3236.

• Stock backyard ponds or other permanent water features with mosquito fish. The fish are free and can be delivered or simply picked up at the district office.

• Report dead birds to the West Nile virus hotline at 1 (877) 968-2473 or online at www.westnile.ca.gov.

• Wear mosquito repellent when outdoors at dusk and dawn. Use a repellent containing one of the following active ingredients: DEET, Picaridin, oil of lemon eucalyptus, or IR3535. 

• Residents interested in staying informed about district activities are encouraged to follow MSMVCD on Twitter and Facebook.
