Prevent Mosquito Bites

  • Adult mosquitoes do not generally survive high winds during a hurricane.
  • Immediately following a hurricane, flooding occurs. Mosquito eggs laid in the soil by floodwater mosquitoes during previous floods hatch. This results in very large populations of floodwater mosquitoes. Most of these mosquitoes are considered nuisance mosquitoes.
  • In general, nuisance mosquitoes do not spread viruses that make people sick. The types of mosquitoes that can spread viruses may increase 2 weeks to 2 months after a hurricane, especially in areas that did not flood but received more rainfall than usual.

The best was to prevent infection from diseases spread by mosquitoes is to prevent mosquito bites. Mosquitoes bite during the day and night. Take the following steps to protect yourself and your family:

  • Use EPA-registeredexternal icon insect repellent
  • Wear long-sleeved shirts and long pants
  • Take steps to control mosquitoes indoors and outdoors

Prevent Contact With Rodents

  • Remove food sources, water, and items that can provide shelter for rodents.
  • Wash dishes, pans, and cooking utensils immediately after use.
  • Dispose of garbage and debris as soon as possible.

For more information, see Rodent Control After a Disaster.

Prevent or Respond to a Snake Bite

  • Be aware of snakes that may be swimming in the water to get to higher ground and those that may be hiding under debris or other objects.
  • If you see a snake, back away from it slowly and do not touch it.
  • If you or someone you know are bitten, try to see and remember the color and shape of the snake, which can help with treatment of the snake bite.
  • Keep the bitten person still and calm. This can slow down the spread of venom if the snake is venomous. Seek medical attention as soon as possible. Dial 911 or call local Emergency Medical Services. Apply first aid if you cannot get the person to the hospital right away.
    • Lay or sit the person down with the bite below the level of the heart.
    • Tell him/her to stay calm and still.
    • Wash the wound with warm soapy water immediately.
    • Cover the bite with a clean, dry dressing.
