DOH-Seminole - Prevent Mosquito-Borne Illnesses

June 28, 2019

Sanford, Fla. - The Seminole County Health Department reminds Seminole County residents and visitors to Drain and Cover, especially during the rainy season. Simple steps can be taken to protect yourself and your loved ones against mosquito-borne illnesses.

"More rainfalls in our area cause water accumulation leading to mosquito breeding sites. There are simple measures that citizens can take to prevent mosquitoes from breeding, such as draining standing water and discarding any items that accumulate water, as well as protecting against mosquito bites. We partner with Seminole County Mosquito Control to educate the
community and keep them safe from mosquito-borne diseases," said Donna Walsh, health
officer for the Seminole County Health Department.

To protect yourself from mosquitoes, remember to "Drain and Cover":

DRAIN standing water weekly to stop mosquitoes from multiplying.

  • Drain water from garbage cans, house gutters, buckets, pool covers, coolers, toys, flower pots or any other containers where sprinkler or rain water has collected.

  • Discard old tires, drums, bottles, cans, pots and pans, broken appliances and other items that aren't being used.

  • Empty and clean birdbaths and pet's water bowls at least once or twice a week.

  • Protect boats and vehicles from rain with tarps that don't accumulate water.

  • Maintain swimming pools in good condition and appropriately chlorinated. Empty plastic
    swimming pools when not in use.

COVER skin with clothing or repellent.

  • Clothing - Wear shoes, socks, and long pants and long-sleeves. This type of protection may be necessary for people who must work in areas where mosquitoes are present.

  • Repellent - Apply mosquito repellent to bare skin and clothing. Always use repellents according to the label. Repellents with DEET, picaridin, oil of lemon eucalyptus, paramenthane-diol, and IR3535 are effective.

  • Use mosquito netting to protect children younger than 2 months old.

COVER doors and windows with screens to keep mosquitoes out of your house.

  • Repair broken screening on windows, doors, porches, and patios.

Residents of Florida are encouraged to report dead birds via the Florida Fish and Wildlife Conservation Commission's site
