West Nile Virus Found In Eastvale

Staff ReportsWest-Nile-WEB

Eastvale– The City of Eastvale recently reported that the first indications of West Nile virus in 2016 were detected in a sample of collected mosquitoes. The mosquitoes tested positive for the virus on June 15, according to the City of Eastvale.

“District staff will continue to canvass the area to look for and treat mosquito breeding sources,” a City of Eastvale news release stated.  “They will also post signs alerting residents of the detection of the virus along with preventative measures the public can take to keep from becoming infected with West Nile virus.”

The Northwest Mosquito and Vector Control District have been routinely monitoring populations of adult mosquitoes and tests groups of adult female mosquitoes for the presence of mosquito-borne viruses.

Specifically, on June 17, 24 and 25, the Northwest Mosquito and Vector Control District performed adult mosquito spray treatments to lower the mosquito population that had been affecting recreational and residential areas along the Santa Ana River in the City of Eastvale.

The treatments were conducted between the hours of 3 a.m. and 6 a.m. at the following locations: the Riverwalk Park, the bike trail next to the Santa Ana River, and Granja Vista Wetland located on Citrus Avenue between Riverwalk Park and Eastvale Community Park. Signs were posted prior, informing the public of the activities.

An approved mosquito treatment called Aqua-Reslin was used by the District, focusing on preventing mosquito breeding and killing mosquito larvae before they become flying adults. The Districts also have been working hard to use Integrated Pest Management Practices in the areas.

According to the District, due to the elevated trap counts, they decided that adult mosquito control via truck mounted ground fogger is the best means to control the current mosquito populations.

The District urges the public to conduct routine inspections on their properties for mosquito breeding sources.  Please look for any standing water around your home or neighborhood.  Remove the water source or contact the Northwest Mosquito and Vector Control District to inspect and treat the source.  Remember, mosquitoes can complete their lifecycle in just one week in a water source as small as a bottle cap.

Northwest Mosquito and Vector Control District urges residents to take the following precautions to avoid being bitten by mosquitoes:

  • Eliminate any standing water around your house and stock permanent ponds with fish that eat mosquito larvae.
  • Make sure all windows and door screens on your house are in good repair and tight fitting.
  • Wear protective clothing (long pants and long sleeves) or wear a mosquito repellant that contains DEET®, Picaridin, Oil of Lemon Eucalyptus or IR 3535 when outside.
  • Limit outdoor activities during dusk and dawn hours. This is particularly important for elderly and small children.
  • Make sure roof gutters drain properly. Clean clogged gutters in the spring and fall.
  • Contact the Northwest Mosquito and Vector Control District to report standing water or mosquito activity.

An infected mosquito can bite any animal, but not all animals will become infected. The disease most often affects birds, but occasionally causes disease in other animals as well, such as horses.

If you find a dead bird, particularly a dead crow or other corvid (e.g., jay, magpie, raven), please call 877-WNV-BIRD (877-968-2473) promptly. Also make sure you do not touch the bird. Dead birds will be submitted for testing for mosquito-borne viruses.
