Virginia Beach Reports Increase in Positive West Nile Virus Samples

Friday, September 11, 2015

​While Labor Day marks an unofficial end of summer for some, mosquito season in Virginia Beach continues to thrive.

The Virginia Beach Public Works Mosquito Control Biology Lab has detected 7 mosquito samples this week that are positive for West Nile Virus (WNV) which is high at this point in the season.  Normal numbers for one entire mosquito season are 7 for WNV.

“While summer may be over in the minds of many people,” said Jennifer Pierce with the Mosquito Control Biology lab, “we are coming up to the height of mosquito season.  This increased activity will most likely continue for another 6-8 weeks.”

Mosquito Control’s night ULV crews have increased night time spraying, concentrating in the areas of increased positives, particularly in the Kempsville area of the city.  They have also increased their day time spraying of breeding sites.

Most WNV mosquitos are most active after dark, so anyone who plans on being out for any length of time in the evening should be sure and use mosquito repellent.

Other tips to follow are:

  • Wear long, loose and light-colored clothing.
  • Use insect repellent products for both adults and children.
  • Follow label instructions when using insect repellents.

Residents can also help by eliminating mosquito breeding areas on their property:

  • Turn over or remove containers in your yard where rainwater collects, such as potted plant trays, buckets, or toys.
  • Empty bird baths once a week.
  • Remove old tires from your yard.
  • Clean roof gutters and downspout screens.
  • Eliminate standing water on flat roofs, boats, and tarps.
  • Clear obstructions in ditches so they flow and drain. Fill in puddles with soil, or a mixture of sand and gravel, or dig drainage ditches to drain puddles.
  • If puddles or ditches cannot be drained or filled in, treat standing water with mosquito larvicides (dunks or granules) that can be purchased at any hardware store.

Severe illness in humans from WNV is extremely rare - less than 1% of those infected develop any serious problems.

Property owners at the trapping sites have been contacted and advised, and lab officials will continue to consult with the other mosquito control districts throughout the Hampton Roads region.
