County targets container breeding in mosquito control effort
Pinellas County Mosquito Control is intensifying efforts to reduce mosquito populations by focusing on container breeding, a significant contributor to the spread of mosquito-borne diseases such as dengue, chikungunya and Zika. The agency emphasizes the importance of eliminating standing water in man-made containers, which serve as breeding grounds for mosquitoes.
Caroline Scott, Senior Environmental Specialist with Pinellas County Mosquito Control, shared during a recnt press conference that mosquitoes require only a quarter inch of water to breed. In warmer months, they can develop from eggs to adults in as little as five to seven days. Common household items like buckets, children’s toys, tires, planters and even tree holes can collect water and become breeding sites. Residents are advised to inspect their properties weekly and remove any standing water to disrupt the mosquito life cycle.
To assist in these efforts, Pinellas County is hosting a free tire disposal event Saturday, April 19, from 9 a.m. to 1 p.m., at three locations: HHW North in Clearwater, Walsingham Park in Seminole and Lealman Exchange in St. Petersburg. Residents can drop off up to 12 tires (without rims and no larger than 36 inches in diameter) at no cost.
In addition to removing standing water, the county recommends using Bacillus Thuringiensis Israelensis (BTI), a naturally occurring bacterium that targets mosquito larvae. BTI is available in various forms, such as granules and tablets, and can be applied to areas where water cannot be easily drained, like bromeliads and tree holes. It is safe for humans, pets and other wildlife.
Pinellas County employs an Integrated Pest Management (IPM) approach, combining physical, biological and chemical methods to control mosquito populations. This includes the use of mosquito-specific larvicides like BTI, insect growth regulators such as Methoprene and the introduction of mosquitofish (Gambusia affinis) into bodies of water to consume mosquito larvae. These strategies aim to prevent mosquitoes from reaching adulthood and reduce the reliance on adulticide treatments.
The county also encourages residents to prepare for the upcoming hurricane season by including mosquito protection items in their emergency kits. Recommended items include EPA-approved insect repellents containing DEET, Picaridin, IR3535 or oil of lemon eucalyptus, as well as long-sleeved, light-colored clothing and materials to repair window and door screens. These measures can help protect individuals from mosquito bites, especially in the aftermath of storms when mosquito populations may surge due to increased standing water.
Residents experiencing mosquito issues can request a free service from Pinellas County Mosquito Control by calling (727) 464-7503 or submitting a request through the county’s mobile app. Technicians will assess the situation, identify breeding sources and implement appropriate control measures.
