Alert! West Nile Mosquitoes in Orangeburg

See the July 26 article in The Patch:
West Nile Virus Found in Mosquitoes in Orangeburg
The infected mosquitoes were collected in Orangeburg during the week of July 10 as part of the county's ongoing West Nile Virus surveillance efforts. 

Mosquito Life Cycle Depends on Water
With the current drought status, standing water may not be a problem, but the mosquitoes who carry this disease can lay eggs in very little water, such as the rims of upside down pots.  If you see see some larvae swimming in any water in the Garden, please dump it!  

How long each stage lasts depends on both temperature and species characteristics. For instance, Culex tarsalis might go through its life cycle in 14 days at 70 degrees F and take only 10 days at 80 degrees Fahrenheit. Some species have adapted to go through their entire life cycle in as little as four days or as long as one month.  Once the adult mosquito emerges, some will travel as much as 40 miles or more for a meal according to the American Mosquito Control Association!

Outdoor protection:
  • Suggested repellents: Mosquitno: DEET, picaridin, IR3535, oil of lemon, eucalyptus
  • Dark colors attract mosquitoes.  Wear lighter colored clothing
  • Caught in the Garden with no repellent and dusk coming on?  Try rubbing tansy on your exposed skin to repel the mosquitoes.  It grows both in the Park and Herb garden.  Ants and other insects hate it.  The odor is quite distinct and the chemistry seems not to agree with many insects we love to hate.
  • Here is a list of 31 plants that repel mosquitoes
