West Nile Virus detected in mosquitoes in St. Louis County

SAINT LOUIS COUNTY, Mo. (KMOV) – Officials say mosquitoes carrying West Nile Virus have been found from Lemay to Florissant in St. Louis County, though no human cases were reported.

The virus has been found in mosquitoes in North County, Bel-Ridge, Normandy, Olivette, Jennings and unincorporated Lemay.

“Positive mosquito tests are a reminder that preventative measures are important,” said Saint Louis County Health Department Director Dr. Dolores Gunn. “Even though serious West Nile Virus cases in humans are rare, it is important to minimize our exposure. We can do this by eliminating opportunities for mosquitoes to breed and multiply, and protect ourselves by using repellants.”

Here are some steps people can take to reduce the number of mosquitoes:

- At least once a week, drain water from garbage cans, buckets, toys, flowerpots, wading pools, pet dishes, and other objects that collect water. Change water in birdbaths at least once a week.

- Mosquitoes test positive for WNV/Two

- Keep gutters cleaned out, and repair any tears in door and window screens.

- Wear long-sleeved shirts, long pants and light colors outdoors.

- Spray clothing with repellents containing DEET or picaridin, making sure to follow the directions on the label.

- Look for products containing the active ingredient methoprene or Bti (Bacillus thuringiensis israelensis) to place in birdbaths or ponds, to prevent mosquitoes from developing.

- Flexible drainage pipe is commonly used to drain water from downspouts. A big drawback is that it holds water and breeds mosquitoes if not properly sloped when installed.
