The Greater Los Angeles County Vector Control District has confirmed 11 additional mosquito samples positive for West Nile virus, bringing the number of positive samples within the district’s service area to 25 this year.
Positive samples were collected in four new areas — Montebello, Santa Fe Springs, South Whittier and Woodland Hills.
So far this year, no West Nile-infected mosquito samples have been discovered in the Santa Clarita Valley.
Mosquito control is a shared responsibility and residents must take an active role in reducing the threat of WNV in their neighborhoods by taking the following steps:
* Eliminate standing water in clogged rain gutters, rain barrels, discarded tires, buckets, watering troughs or anything that holds water for more than a week.
* Ensure that swimming pools, spas, and ponds are properly maintained.
* Change the water in pet dishes, birdbaths and other small containers weekly.
* Request mosquitofish from your local vector control district for placement in ornamental ponds.
* Wear EPA-recommended insect repellent when outdoors where mosquitoes may be present.
* Report neglected (green) swimming pools in your neighborhood to your vector control district.
