Protect yourself from mosquitoes this Fourth of July
Elk Grove, Ca— The Sacramento-Yolo Mosquito & Vector Control District confirmed that West Nile virus (WNV) activity is increasing in urban areas especially within the city of Sacramento. Laboratory results obtained today confirmed more mosquito samples and dead birds tested positive for the virus in two different areas of the city. The two sites where virus is currently concentrated include south Natomas and the area between Elder Creek Rd. and Florin Rd. west of Power Inn Rd.   “The extreme heat we’ve seen in the last few days has definitely increased mosquito populations and we’re starting to see widespread activity,” said Gary Goodman, District Manager.  “We are closely monitoring these areas as they are becoming hot spots for the virus” indicated Goodman.

The rise in West Nile virus activity comes at a time when residents will be enjoying the outdoor activities for the 4th of July holiday and the District reminds the public to take protective measures against mosquitoes. “Many will be participating in family BBQ’s and watching fireworks around dusk, a time when mosquitoes are looking to bite. We urge everyone to wear an effective repellent to protect themselves from mosquito bites. All it takes is one bite from an infected mosquito to get the virus” added Goodman.
The Centers for Disease Control recommends using an insect repellent that contains the active ingredients DEET, Picaridin, IR3535 or the plant based Oil of Lemon Eucalyptus. Always follow label directions when applying repellent.
In response to the ongoing WNV activity, the District will continue surveillance efforts through testing of mosquito samples and dead bird reports as well as controlling adult mosquitoes with ground fogging in areas of concern.
In 2022, 5 human West Nile virus cases were confirmed in Sacramento County and 3 in Yolo County. Throughout California, there were 216 human cases including 15 fatalities.
