Frequently Asked Questions

A: We do not operate on a schedule. We make daily decisions where we will be spraying based on the number of mosquitoes we find in traps and/or landing rate counts reported by our inspectors.
A: The amount of times an area is sprayed is dependent on mosquito species and mosquito numbers. We have 42 PCMCD traps throughout the county that we check daily. We also set weekly CDC (Center for Disease Control) traps to help us focus on the areas in the county needing our immediate attention.
A: We do not send the trucks out on request. We are required by the state of Florida to provide mosquito population data to justify our spray efforts.

A: PCMCD works closely with all Pasco County bee keepers registered by the state of Florida. Please contact our office to discuss the options.
A: There are over 45 mosquito species in Pasco County. PCMCD inspectors need to determine which species you are dealing with so that we can provide a management plans specific to you and your neighborhood’s needs.

A: To address a stagnant pool, please call Pasco County Code Enforcement. Although pools are not a likely breeding source for mosquitoes, we can inspect and treat for mosquitoes if they are found.
A: Our applications are situation specific. Please contact our office and we can determine what chemical was used in your area.
A: All our spray trucks are equipped with GPS and a PCMCD accurate flow spray system. We have records of where our trucks traveled, how fast they were going, and if they were spraying. These records are reviewed and managed daily to ensure proper treatment.
A: Typically, our spray technicians suspend treatment when people are observed outside in the path of treatment. If you notice our spray trucks traveling down your road or in your neighborhood, please observe from inside your home so we can provide treatment in your area.
A: There is a yellow light located on the roof of the truck. The light will be flashing when we are conducting treatments.
A: Most adult female mosquitoes live 2-3 weeks, while the males only live for a week or less. Only the female needs blood for the nutrition of their eggs.
A: Some mosquito species that breed in containers around the house, such as Aedes aegypti and Ae. albopictus, have limited flight ranges of less than 1,000 feet. Most mosquito species have flight ranges of 1-3 miles. Saltmarsh mosquitoes are often the strongest fliers and are known to travel over 10 miles for a bloodmeal.
A: The US EPA has evaluated the pesticides we use for mosquito control for their safety and have determined that they pose no risk to birds or mammals if used according to the product label directions.

The active ingredients in the pesticide break down quickly and do not leave a toxic residue. You can reduce your exposure to the spray by staying indoors during spraying. There are otherwise no special precautions that should be taken once the pesticide clears the area.
