What did the Department of Health advisories mean for Duval?
The Florida Department of Health issued mosquito-borne illness advisories for Duval in past wet seasons, including 2024. An advisory is a public notice that a mosquito-borne illness is circulating in an area, and it is a reason to step up personal protection and yard clearing for the period it covers.
An advisory is not a diagnosis, and it does not mean every household is at risk. It is a signal from the public health office that the local conditions are right for transmission, and it tells residents what to do to reduce their exposure during the period.
The 2024 advisory is one of several in past wet seasons, according to the Department of Health's notices. A homeowner who checks the department's listings each season can see whether an advisory is in effect and for what period.
The advisory does not change the basic steps. Clearing water, protecting people and watching for symptoms are the same whether or not an advisory is in force. The advisory simply makes the steps more urgent.
What should a household do after each storm?
After a storm, empty the containers, clear the gutters, drain the saucers and fill low spots within a day or two. This is the household's most effective wet-season step, and it costs nothing.
Standing water is the thing mosquitoes need to breed. A storm that fills buckets, tubs and plant saucers gives them a supply of breeding sites within hours, and an empty container gives them nothing.
Gutters that hold water after rain are a breeding site as well as a moisture problem, and they can overflow onto the wall. Clearing them after a storm serves both purposes.
Low spots in the lawn and in the drive also hold water. Filling or grading them so the water drains away is a longer job, but it reduces the wet-season breeding that the lot produces.
- Empty containers, tubs and buckets within a day.
- Drain plant saucers and pet bowls after rain.
- Clear gutters and check the downspouts.
- Fill or grade low spots that hold water for days.
How should people protect themselves outdoors?
Wear long sleeves and long trousers where the weather allows, use a repellent that the label allows, and keep screens intact. Timing matters too, since many biting mosquitoes are most active around dusk and dawn.
Clothing is the most reliable barrier that a person controls. Light, loose long sleeves and trousers keep the skin covered, and they are most useful in the evening when the biting is heaviest.
Repellents are used as the label directs. Check the label for the age and the strength that is allowed, and follow the instructions for reapplication. A repellent that is used correctly is a useful part of the plan, but it is not a substitute for clearing the water.
Screens and doors are the household's barrier indoors. A torn screen or a door left open in the evening lets adults in. A quick check of the screens before the wet season begins, and a habit of closing the door at dusk, removes a source of exposure.
Which symptoms need a doctor, and what should be said?
Fever, severe headache, rash or joint pain after outdoor exposure should prompt a call to a doctor, and the person should mention recent mosquito bites and time spent outdoors. A pest company cannot diagnose an illness, and the household plan should say so clearly.
A household plan should name who to call first, usually the family doctor or a nurse line, and it should say what to mention: the symptoms, when they started, and any recent time outdoors or bites. That detail helps the clinician decide what to check.
A child, an older adult or someone with a health condition should be watched more closely, and the threshold for calling should be lower. The plan should say that, so nobody waits to see whether a symptom passes.
The pest company's role is the yard and the home. Medical questions go to a doctor, and the household should not rely on a pest visit to answer them.
- Fever, severe headache, rash or joint pain after outdoor time.
- The date the symptoms began and any recent bites.
- Which family members were outdoors and for how long.
- Who to call first and when to seek urgent care.
When should a private visit be added to the household plan?
Add a private yard visit when standing water or resting sites persist after the household steps, or when biting adults remain in the shade of the lot. The visit treats the lot and records what was done, while the household keeps up the daily steps.
A yard that has been cleared and still produces biting adults has a resting site or a breeding source the household has not found. A technician can look for those sources and treat the areas where the label allows.
The visit does not replace the household's own clearing. The homeowner still empties containers after rain, and the technician's list is most useful when the homeowner has already done those tasks.
The wider area is covered by the city program, which is requested separately. A private visit and a city request can both be used in the same season.
