If you spray your clothing, there's no need to spray repellent containing DEET on the skin under your clothing. When possible, wear long-sleeved shirts and long pants treated with repellents containing permethrin or DEET since mosquitoes may bite through thin clothing.
Don't directly apply repellents containing permethrin to exposed skin. Consider staying indoors at dawn, dusk, and in the early evening. These are peak hours for mosquito bites, especially those mosquitoes that carry the West Nile virus. Limit the number of places for mosquitoes to lay their eggs by getting rid of standing water sources from around your home.
To boost your protection from insect repellent, remember: Sweating, or water may call for reapplication of the product. If you aren't being bitten, you don't need to reapply repellent. Use enough repellent to cover exposed skin or clothing. Don't apply repellent to skin that's under clothing. Heavy application isn't needed for protection.
Don't apply repellent to cuts, wounds, or irritated skin. After returning indoors, wash treated skin with soap and water. Don't spray aerosol or pump products in enclosed areas. Don't apply aerosol or pump products directly to your face. Spray your hands and then rub them carefully over the face, avoiding your eyes and mouth. Request an Appointment at Mayo Clinic.
