To avoid mosquito bites, citizens are advised to take extra precautions when spending time outdoors during the hours of dusk to dawn during the summer months. Wearing long sleeve tight knit shirts and long pants, limiting time outdoors during these times, and using a mosquito repellent such as DEET, Picardin, or oil of lemon eucalyptus are good actions to take to prevent bites. Citizens can help prevent mosquito re-population by eliminating standing water on their property.
