Dump and Drain to Prevent Mosquitoes from Breeding

Hurricane Irma Update No. 49

Hillsborough County, Fla. (Sept. 15, 2017) - Hurricane Irma's windblown and water-driven debris scattered across Hillsborough County, as well as floodwaters, means additional breeding grounds for mosquitoes. Any debris or other items that hold water - from a Styrofoam cup to a torn plastic tarp - can allow mosquitoes to breed by the thousands. It's important to drain this water and dispose of, cover, or move these items to prevent the spread of mosquitoes.

The easiest way to prevent mosquito bites is to stop them from breeding in the first place. Mosquito larvae need water to grow, so the most effective method to keep them from reproducing is to deprive them of water.

Follow these tips:

  • Wear long-sleeved shirts, long pants, and insect repellent while you're out cleaning up your yard.
  • Pick up and drain water from overturned garbage cans and flower pots, as well as pool covers, coolers, toys, buckets, watering cans, kiddie pools, and any other containers where rainwater collected.
  • Clean out rain gutters and downspouts, especially those that are clogged with storm debris.
  • Discard old tires, drums, bottles, cans, pots and pans, broken appliances, and other items that may collect water.
  • Check and correct chlorination levels in pools which received more rainwater during Irma.
  • Empty and clean birdbaths and pet water bowls.
