The Texas Department of State Health Services recommends practicing the “Four D’s” to help keep family and friends safe from mosquito bites:

Dusk/Dawn: Stay indoors during dawn and dusk, when mosquitos are most active
DEET: Use an insect repellant containing DEET
Dress: Wear long sleeves and pants when outside to protect skin against bites
Drain: As discussed on the Protect Your Home page, remove all standing water outside your home or business.

Additional tips
• Apply insect repellent to exposed skin whenever you plan to be outdoors during mosquito season. Repellents are formulated and sold as aerosols, creams, solids (sticks) and liquids, and their protection may generally be expected up to last six hours following application. The more active ingredient a repellent contains, the longer it can protect you from mosquito bites. (A higher percentage of the active ingredient in a repellent does not mean that the protection is better, just that it will last longer.)
• Keep repellents away from eyes, nostrils and lips
• Because repellents may irritate the eyes and mouth, avoid applying repellent to the hands of children.
• Spray clothing with repellents containing permethrin or another EPA-registered repellent since mosquitos may bite through thin clothing. Do not apply repellents containing permethrin directly to exposed skin.
• Place mosquito netting over infant carriers when you are outdoors.

Please note: Vitamin B and "ultrasonic" devices are NOT effective in preventing mosquito bites.
