Pinellas County Mosquito Control is stepping up its fight against mosquito-borne diseases like dengue, chikungunya, and Zika by targeting one of the main culprits: man-made containers that collect standing water. These everyday items—ranging from buckets to planters—can quickly become breeding grounds for mosquitoes.

At a recent press conference, Caroline Scott, Senior Environmental Specialist with the agency, highlighted how little water mosquitoes need to thrive—just a quarter inch. In warm weather, mosquito eggs can hatch and mature into adults in as little as five to seven days. Common household objects like toys, tires, and even natural features like tree holes can harbor enough water to fuel mosquito growth. Officials urge residents to check their properties weekly and eliminate any standing water.

To support these efforts, the county is hosting a free tire disposal event on Saturday, April 19, from 9 a.m. to 1 p.m. Residents can drop off up to 12 tires (no rims, max size 36 inches) at three locations: HHW North in Clearwater, Walsingham Park in Seminole, and Lealman Exchange in St. Petersburg.

In areas where standing water can’t be drained—like inside bromeliads or tree holes—the county recommends using Bacillus Thuringiensis Israelensis (BTI). This natural bacterium kills mosquito larvae but is safe for people, pets, and wildlife. It comes in granules, tablets, and other forms for easy use.

Pinellas County’s mosquito control strategy follows an Integrated Pest Management (IPM) model, which combines physical, biological, and chemical approaches. Along with BTI, the county uses insect growth regulators like Methoprene and introduces mosquitofish (Gambusia affinis) to water sources where they feed on mosquito larvae—helping reduce the need for adult-targeted spraying.

With hurricane season around the corner, residents are also encouraged to prepare by adding mosquito protection to their emergency kits. Items like EPA-approved repellents (with DEET, Picaridin, IR3535, or oil of lemon eucalyptus), light-colored long sleeves, and screen repair materials can help prevent bites during the post-storm mosquito surge.

Anyone dealing with mosquito problems can request a free service by calling (727) 464-7503 or submitting a request via the county’s mobile app. Technicians will inspect the area, identify breeding sources, and take steps to control the problem.
