The best way to avoid mosquitoes is to stay indoors after dusk and to stay away from wet places where mosquitoes thrive. Of course, in the summer it's likely that you want to be outside, often at the peak mosquito hours.
Because West Nile virus will return every summer, it's essential that you do all that you can to prevent being bitten by a West Nile virus-infected mosquito as you enjoy your summer activities. When you are outside, choose a repellent that best fits your needs for that situation. Mosquito repellents are not all the same. Some brands have different ingredients than others. A repellent made for adults may not be the right choice for kids, or one repellent may only offer a half hour of protection while another gives five hours of protection.
When you are choosing a repellent, read the label and look for one that has been approved by the CDC and that is effective against culex mosquitoes, the ones that carry West Nile infection. Also, ask yourself the following questions so you know what is right for you:
