Mosquito-Borne Illness Prevention

Florida Department of Health - St. Johns County

Immediately following a storm, flooding may occur. Mosquito eggs laid in the soil during previous floods can hatch and result in very large populations. Most of these mosquitoes are considered nuisance mosquitoes, however it’s essential to protect yourself and your family from mosquito breeding and mosquito-borne illness.

PROTECT YOURSELF WITH REPELLENT

  • Always read label directions carefully for the approved usage before you apply a repellent.
  • Apply insect repellent to exposed skin or clothing, but not under clothing.
  • Treat clothing and gear with products containing 0.5% permethrin. Do not apply directly to skin.
  • Some repellents are not suitable for children. Ensure repellent is safe for children and age appropriate.

STOP MOSQUITOES FROM BREEDING

MOSQUITOES CAN LIVE INDOORS AND WILL BITE DAY OR NIGHT.

  • Mosquitoes breed by laying eggs in and near standing water.
  • As little as one teaspoon or bottle cap of water standing for more than one week is enough for mosquitoes to breed and multiply.

AROUND BUILDINGS

At least once a week, empty or cover anything that could hold water, such as:

  • Buckets
  • Toys
  • Child Pools and Pool Covers
  • Birdbaths
  • Trash, Containers, and Recycling Bins
  • Boat or Car Covers
  • Roof Gutters
  • Coolers
  • Pet Dishes
  • Tires

KEEP THEM OUTSIDE

  • Use Air Conditioning
  • Keep Screens on All Windows
  • Repair Holes in Screens
  • Keep Exterior Doors & Windows Closed
