Test Sample Positive for West Nile Virus

The New Hampshire Department of Health and Human Services has notified the City of Keene that a mosquito sample has tested positive for West Nile Virus in the species Culex Pipiens. This is considered a low risk in that they are primarily a bird feeder and do not appear to be a major biting pest. 

 

On the recommendation of Municipal Pest Management Services, Inc., the City of Keene has sprayed the perimeter areas of Keene High School, Keene Middle School, some of Wheelock Park, and the baseball fields on Wood St. on Thursday, September 19, 2013. The application they applied was to the vegetated perimeter areas of each site using the residual insecticide Crosscheck Plus (active ingredient: bifenthrin) but not adjacent to water bodies. This is considered to be a low-risk insecticide that has a very low mammalian toxicity but is very effective for insects. The application will provide extended mosquito control for three to four weeks. There is no odor associated with the spray and it is dry within ten minutes of application.

 

Some of the recommendations from the Department of Health and Human Services to reduce the risk of mosquito bites are to;

 

  1. Wear protective clothing such as long sleeve shirts and pants, and socks.
  2. Consider using an effective bug-repellent.
  3. Eliminate standing water such as in any container such as buckets, or containers.
  4. Have all window and door screens tight and secure.
