11 Additional Batches of Mosquitoes Test Positive for WNV in Past Week

September 15, 2017

Multiple batches of mosquitoes collected by the Metro Public Health Department’s Pest Management Division have tested positive for West Nile virus.  The batches of mosquitoes were trapped in the following locations:

Antioch – Near the intersection of Edge O Lake Drive and Murfreesboro Pike
Bordeaux – Near the intersection of Kings Lane and Clarksville Highway - Three batches tested positive at this location
Donelson – Near the intersection of Lebanon Road and McGavock Pike
North Nashville --  Near the intersection of Buchanan Street and 12 Ave. North - Two batches tested positive at this location
Priest Lake – Near the intersection of Anderson Road and Smith Springs Road - Three batches tested positive at this location
Waverly/Belmont – Near the intersection of 12 Ave. South and Acklen Ave.

The Health Department’s Pest Management staff continue to monitor standing water in all areas of Davidson County looking for mosquito larvae.  Staff will apply a granular larvicide to any areas where mosquito larvae are present.

Staff began trapping mosquitoes in all parts of Davidson County the first week in May. Health Department staff sends the mosquitoes to the Tennessee Department of Health’s lab for testing.  One human case was reported in Davidson County in August.  Health officials have no plans to spray to kill adult mosquitoes.

The Health Department recommends taking the following steps to protect against biting mosquitoes, including:

  • Limit time outdoors at dusk and nighttime hours when mosquitoes are present.
  • If you must be outdoors then wear a mosquito repellent that is approved for use by the CDC – those include products that contain DEET, Picaridin, and Oil of Lemon Eucalyptus.
  • Wear shoes, socks, long sleeve shirts and pants when outdoors during dusk to dawn when mosquitoes are most prevalent.  Clothing should be light colored and made of tightly woven materials to keep mosquitoes away from the skin.  Pant legs should be tucked into shoes or socks, and collars should be buttoned.
  • Make sure your windows and doors have screens and are in good repair.

Health Department officials recommend taking steps to reduce mosquito breeding areas.  This includes:

  • Reduce or eliminate all standing water in your yard – especially in children’s toys, bird baths, clogged gutters, tires, flowerpots, trashcans, and wheelbarrows.
  • Aerate ornamental pools or stock them with Gambusia fish.
  • Apply mosquito dunks in standing water areas on your property.
  • Cut back overgrown vegetation (mosquito hiding areas).

Health Department staff began monitoring standing water in all areas of Nashville in late February.  Staff applies larvicide when mosquito larvae are present to kill the larvae before they become adult mosquitoes.

Please visit the Health Department’s website and Facebook and Twitter pages for updates on West Nile Virus.  Davidson County residents that are having mosquito problems can call 615-340-5660 to arrange to have a Pest Management staff member come and inspect your property and provide mosquito control and prevention advise.  Pest Management staff will check your property for standing water and apply the larvicide if mosquito larvae are present.
