Mosquito Protection

In August of 2016, two West Nile Virus positive mosquito pools were detected, so it is important not to leave your bug spray at home while enjoying this last month of summer!

Infected mosquitoes spread West Nile Virus (WNV), which can be serious, life-altering and even fatal. Mosquitoes that carry WNV do show up in Montana, and since it’s impossible to tell whether a mosquito carries the virus or not, bite prevention is your best protection.

How can you prevent mosquitoes and bites? Follow the 4 D’s!

  • DEET-Apply repellent that includes DEET, Picaridin, or oil of lemon eucalyptus to exposed skin and clothing. These are the three most effective insect repellants. Permethrin may be used on clothing but can be very toxic, so use it with extreme caution. Do not spray aerosols on your face—spray it into your hands and rub on your face.
  • Dusk and Dawn-This is when mosquitoes are most active. Try to avoid outdoor activities during these times.
  • Drain Standing Water-Standing water is the perfect breeding ground for mosquitoes. Drain such areas around your home (gutters, pools, tires, buckets, water bowls, etc.).
  • Dress Appropriately-Wear long-sleeved shirts, long pants and socks.

Fortunately, most people that become infected with WNV will show no symptoms. Those that do have symptoms may experience:

  • Fever
  • Headache or body aches
  • Nausea and vomiting
  • Skin rash

In few individuals (about 1 in 150), other, more serious symptoms may also include:

  • Disorientation
  • Tremors or convulsions
  • Muscle weakness
  • Vision loss
  • Numbness or paralysis

If you develop any of these symptoms, seek medical attention immediately!

Enjoy your time outside this summer, and make sure you don’t carry anything back inside – protect yourself from mosquitoes! Find out more about the prevention, transmission and treatment of WNV by downloading our printable fact sheet here.
