Control Efforts

PCMCD implements an Integrated Mosquito Management program that is environmentally friendly and a well-balanced, scientific approach to controlling mosquitoes. PCMCD reduces mosquito populations in various ways, including aquatic weed management, the use of biological control agents, and insecticides, which can be effective in controlling mosquito larvae or mosquito adults. Mosquito populations can increase rapidly depending on flooding, tidal flows and general weather conditions. Mosquito populations must be constantly monitored to determine which species are infesting a particular area and to assure that control is carried out in the most efficient manner.

Control Efforts

There about 45 mosquito species in Pasco County and some of those species differ in habitat, behavior and preferred source of blood. Organized mosquito control is necessary because mosquitoes are not only a nuisance as biting insects, but are also involved periodically in transmitting diseases to humans and animals.

Controlling mosquitoes in the larval stage (larviciding) is preferred because the larvae are often concentrated in large numbers in various aquatic habitats. If the larvae are successfully controlled in these confined areas, this prevents a major emergence of biting adult females. Larviciding is conducted by truck unless access is limited or timing of treatment is critical. In these cases, it is often necessary to use helicopters to inspect and treat for larvae.

If you see us out in one of our “Omaha Orange” helicopters during the day, we are most likely conducting inspections and/or controlling the juvenile (larval) stages of mosquitoes that occur in both salt and fresh water environments. Larval control is one of the main aspects of our integrated approach to effectively manage mosquito populations.

Mosquitoes are not only a nuisance as biting insects, but are also involved in transmitting diseases to humans and animals.

A few mosquito species utilize plant roots of select invasive plants to obtain oxygen. The best way to control these species is by controlling the invasive weeds. If you see our airboats, Argo or Jon boat in your community water bodies, we are controlling mosquitoes by removing invasive, non-native weeds.

Ultra Low Volume (ULV) trucks are generally used in areas with good road access. We actively pursue pestiferous adult mosquitoes during the summer rainy season, but if we have major rainfall events in the winter months, this can trigger a major mosquito emergence. We operate our ULV truck fleet 4-5 hours at night, beginning 15 min after sunset. Periodically, conditions are conducive for extremely large numbers of adult mosquitoes. When this occurs we will utilize our planes to treat large areas for mosquitoes. If you see us out in our white twin-engine Aztec plane at dusk, or note our presence in the dark, we are controlling the adult mosquitoes.
