Protect Yourself From Mosquitoes

Late summer is the most common time of year for mosquito activity and mosquitoes in Orleans Parish have tested positive for St. Louis encephalitis and West Nile virus. 

How to protect yourself from mosquitoes

  • Limit activities when mosquitoes are most active (dusk to dawn)
  • Use air-conditioning or make sure window and door screens are in good repair to prevent mosquitoes from getting inside
  • If you will be outside for long periods of time, wear long, loose, light-colored clothing that covers the skins
  • Use repellents containing DEET and always follow the recommendations appearing on the product label

How to protect your home from mosquitoes

  • Get rid of standing water around your home where mosquitoes can lay eggs
  • Remove trash, clutter and old tires and other containers that can hold water around your property
  • Change water weekly in containers that cannot be removed, such as pet dishes, bird baths and kiddie pools
  • Place screen on rain barrels or water collecting containers and use the water within a week
  • Treat ornamental ponds or stock them with fish
  • Report illegal dumping, abandoned swimming pools and water leaks by calling 311

Travel Precautions

State Health Officials encourage travelers to take precautions to protect themselves from mosquitoes.  Mosquitoes in other parts of the world including the Caribbean, South America, Asia, Africa or Europe can be infected with chikungunya or dengue virus.  As of Friday, August 29, 2014, 696 chikungunya infections have been report in travelers returning to the United States; Louisiana has confirmed 10 travel-related cases.  In Florida, 139 travel-associated cases and 6 locally-transmitted cases have been reported.  Mosquitoes present in Louisiana that can transmit these viruses include the Yellow fever mosquito and the Asian Tiger mosquito.  Early detection of the symptoms and avoiding mosquito bites will help prevent the disease from spreading.  If you have traveled to the Caribbean or any other endemic areas of the world and have symptoms, seek medical attention immediately, notify your physician of your travel history, and avoid mosquito bites.
