According to the Centers for Diseast Control and Prevention (CDC) you can protect yourself from mosquito bites by:Apply insect repellent to exposed skin. Generally, the the more active ingredient a repellent contains the longer it can protect you from mosquito bites. A higher percentage of active ingredient in a repellent does not mean that your protection is better—just that it will last longer. Choose a repellent that provides protection for the amount of time that you will be outdoors. Spray clothing with repellents containing permethrin or another EPA-registered repellent since mosquitoes may bite through thin clothing. Do not apply repellents containing permethrin directly to exposed skin. Do not apply repellent to skin under your clothing. When weather permits, wear long-sleeved shirts and long pants whenever you are outdoors. Place mosquito netting over infant carriers when you are outdoors with infants. Consider staying indoors at dawn, dusk, and in the early evening, which are peak mosquito biting times. Install or repair window and door screens so that mosquitoes cannot get indoors.
Help reduce the number of mosquitoes in areas outdoors where you work or play, by draining sources of standing water. In this way, you reduce the number of places mosquitoes can lay their eggs and breed.At least once or twice a week, empty water from flower pots, pet food and water dishes, birdbaths, swimming pool covers, buckets, barrels, and cans. Check for clogged rain gutters and clean them out. Remove discarded tires, and other items that could collect water. Be sure to check for containers or trash in places that may be hard to see, such as under bushes or under your home.
Note: Vitamin B and "ultrasonic" devices are NOT effective in preventing mosquito bites.
You can contact your local health department for the latest information on the virus in your area. Its also a good idea to take steps to lower your risk of getting a mosquito bite:
A West Nile virus vaccine is available for horses only. If you own horses, you may think about getting the vaccine for them. The death rate from West Nile is much higher in horses than in humans.
Researchers are working to create a vaccine that prevents West Nile virus in humans.
