Tips to avoid bites:

• Avoid prolonged outdoor exposure during dawn and dusk. These are the times when mosquitoes are the most active.
• Wear long sleeves and pants when outdoors to protect against mosquitoes bites.
• Protect yourself against mosquitoes by using an effective insect repellent, such as DEET, picaridin, Oil of Lemon Eucalyptus, or IR3535. Follow labeled instructions.
• Keep doors, windows, and screens in good working condition to prevent mosquitoes from entering your home.
