Q: How does the spray request work?

A: Mosquito spraying is a service provided by the Clay County Board of County Commissioners. You contact our office by phone 904-284-6335, and provide us with your name, telephone number, address including the city and zip code, name of your development (if applicable), and gate code (if applicable). Then, your location will be scheduled to be sprayed by a truck.


Q: Do you have a set schedule for spraying mosquitoes?

A: Spraying for adult mosquito outbreaks occurs on an as-needed basis, and only if mosquito populations meet state guidelines for treatment. As such, we make daily decisions based on the data gathered from our 60 traps set across the county.  This allows us to assign spray trucks where the chemical application is most needed and will be most effective


Q: How many phone calls do you need to spray in my area?

A: The number of phone calls for service does not determine when or where treatment for adult mosquitoes will be done.


Q:  Do you provide public education about mosquitoes?

A:  Yes, mosquito control personnel are willing to provide educational programs to groups throughout the year.  Contact for more info.



Q: How many types of mosquitoes are there?

A: There are over 3,000 different types of mosquitoes. In Florida we have 80 different



Q: Do all mosquitoes bite?

A: No, only female mosquitoes bite. Females need blood to make eggs. Male

mosquitoes feed on plant sugar. Only some species of mosquito like to bite people.


Q: Where are all the mosquitoes coming from?

A: Immature mosquitoes live and develop in standing water. The location depends

upon the species. There are mosquitoes that breed in salt marshes, swamps, crab

holes, ponds, swales, bromeliads and even small containers like buckets. As adults,

mosquitoes prefer nice shady places around vegetation. Chances are, if mosquitoes

are bothering you at home, they are liking breeding someplace nearby.


Q: Can bites from mosquitoes make me sick?

A: Only a small number of mosquitoes in Florida can transmit pathogens to people.

Just because a mosquito can transmit pathogen does not mean it will ever be exposed

to it. This means that the likelihood of a person getting sick from a mosquito bite is

very low, although it is possible.


Q: What are you doing to keep me and my family safe?

A: Mosquito control works closely with the Department of Health to monitor the

mosquito population and prevalence of mosquito-borne disease. When mosquito

populations are high or there is disease-activity within an area, we make sure to treat

with both larvicides and adulticides to eliminate mosquitoes.



Q: When is spraying scheduled for my neighborhood?

A: Spraying is conducted on an as needed basis, based upon mosquito population monitoring data. Once mosquito populations are above a set baseline, spraying for an area is scheduled.


Q: Are the products that you use safe?

A: The products we use are registered and approved by the Environmental Protection Agency (EPA). These products have undergone extensive testing to ensure that when they applied in a manner consistent with the label that they will not have any significant adverse effects on human health or the environment.


Q: Does mosquito control harm bees?

A: Insecticides used on mosquitoes can potentially harm other non-target insects such as bees, but our spraying, which typically takes place before dawn or after dusk, reduces the potential harm impact because bees are usually inside their hives during this time.  However, it is not always appropriate to treat before dawn or after dusk for certain mosquito species.  Our mosquito control program keeps an up-to-date list of local beekeepers and works with them to protect their hives. If you are a local beekeeper and would like to be added to this list, please contact Clay County Public Works at 284-6335 and request to speak with Mosquito Control.
