Florida is home to multiple tick species that actively bite humans, pets, and wildlife throughout much of the year. A statewide wildlife survey identified six ixodid (hard tick) species across two-thirds of the state’s counties, with the lone star tick accounting for roughly three-quarters of all specimens collected.1PubMed. Distribution and host associations of ixodid ticks collected from wildlife in Florida, USA The disease picture in Florida looks different from what you might expect if your frame of reference is the northeastern United States, but the risks are real and, in some cases, growing.
Which Tick Species Live in Florida
Four hard tick species consistently turn up in Florida surveillance studies and dominate human encounters. The lone star tick (Amblyomma americanum) is the most commonly reported human-biting tick in the southeastern United States and is endemic throughout much of Florida, though its habitat suitability drops off sharply as you move south through the peninsula.2Journal of Medical Entomology. Estimating the Geographic Distribution of Host-Seeking Adult Amblyomma americanum (Acari: Ixodidae) in Florida The Gulf Coast tick (Amblyomma maculatum) is found in coastal and grassland habitats. The American dog tick (Dermacentor variabilis) shows up in brushy areas and along trails. And the blacklegged tick (Ixodes scapularis), the species most associated with Lyme disease in the Northeast, lives in Florida too, particularly in forested areas of the northern half of the state.3PubMed Central.

Less commonly encountered species include Ixodes affinis and Ixodes texanus, each making up less than one percent of ticks collected from wildlife.1PubMed. Distribution and host associations of ixodid ticks collected from wildlife in Florida, USA Florida also harbors soft ticks. A statewide survey collected over 3,000 soft ticks, all identified as Ornithodoros turicata americanus, from sites spanning the northern part of the state. A small percentage of these carried Borrelia turicatae, the spirochete that causes tick-borne relapsing fever.4PLoS Neglected Tropical Diseases. Prevalence, distribution, and phylogenetics of the tick-borne relapsing fever spirochete Borrelia turicatae in the soft tick Ornithodoros turicata americanus in Florida Soft ticks behave quite differently from hard ticks: they feed quickly (minutes rather than days), live in burrows and sheltered spots rather than questing on vegetation, and are rarely noticed by the people they bite.
A North-South Divide Within the State
If you live in the Florida Panhandle or the north-central corridor between Jacksonville and Tallahassee, your tick exposure is meaningfully higher than if you live in Miami or the Keys. Modeling of lone star tick habitat shows that central and northern regions are far more suitable for the species, with very little habitat deemed suitable in the far southern reaches of the peninsula.2Journal of Medical Entomology. Estimating the Geographic Distribution of Host-Seeking Adult Amblyomma americanum (Acari: Ixodidae) in Florida The same pattern holds for tick-borne disease cases: north-central Florida consistently yields most of Florida’s confirmed tickborne illness.
A study of tick abundance in northwestern Florida found that the greatest risk of tick attachment was in campsites, where about 60% of all host-seeking adult and nymphal ticks were collected. The next highest risk area was a walking trail through a recently burned section of forest, accounting for another 28% of collected ticks.5Oxford Academic. Seasonal Distribution and Abundance of Ticks (Acari: Ixodidae) in Northwestern Florida Campsites tend to combine the things ticks need: shade, leaf litter, and a steady stream of warm-blooded hosts walking through.
South Florida is not entirely tick-free, though. The brown dog tick (Rhipicephalus sanguineus) was the only species collected throughout the entire state in a veterinary survey, while the other major species were limited to central and northern counties.6PubMed. Ticks associated with domestic dogs and cats in Florida, USA Brown dog ticks are unusual because they can complete their entire life cycle indoors, making them a year-round nuisance in any part of the state.
When Tick Season Peaks
Florida’s warm climate blurs the neat spring-and-summer “tick season” that people in northern states are used to. Different species peak at different times, and the overlap means there is no truly safe month. Lone star ticks are most likely to be found on humans in spring (adults and nymphs) and summer (larvae). American dog tick encounters are greatest during summer. Blacklegged tick adults, however, are most active in autumn and winter, a pattern that catches many Floridians off guard.7PLoS Neglected Tropical Diseases. Human risk to tick encounters in the southeastern United States estimated with spatial distribution modeling
This staggered timing means you can encounter different species and different disease risks depending on the time of year. A hike through north-central Florida in November may put you in contact with adult blacklegged ticks, while the same hike in May is more of a lone star tick situation. Practically, this argues for year-round precautions rather than seasonal vigilance.
Tick-Borne Diseases That Matter in Florida
Surveys of ticks in north and north-central Florida have detected pathogenic species of Borrelia, Ehrlichia, and Rickettsia in field-collected ticks.3PubMed Central. A Survey of Tick-Borne Bacterial Pathogens in Florida The diseases these pathogens cause overlap with, but are not identical to, the tick-borne illness profile of northeastern states.
Lyme Disease and STARI
Florida has historically been treated as a negligible Lyme disease state, but reported cases have been rising. Florida recorded 84 Lyme disease cases in 2010 and 271 in 2023; the incidence per 100,000 residents more than tripled, from 0.4 to 1.2, over that period. Older adults and women had slightly higher rates, and the north-central region remained the epicenter of transmission. Part of the increase may reflect better surveillance and awareness rather than a dramatic expansion of the pathogen itself, but the trend is clear enough to challenge the old assumption that Florida residents face no Lyme risk.
Complicating things further is southern tick-associated rash illness, or STARI. This condition, spread by the lone star tick, produces a circular rash with central clearing that looks almost identical to the hallmark rash of Lyme disease. The suspected cause is a spirochete called Borrelia lonestari, though that link is still debated. STARI generally resolves on its own or with antibiotics and does not progress to the chronic joint and neurological problems sometimes seen with Lyme disease, but the visual similarity causes confusion for patients and clinicians alike.
Rickettsial Infections
The Gulf Coast tick is a confirmed vector of Rickettsia parkeri, which causes a spotted-fever illness milder than Rocky Mountain spotted fever but still capable of producing fever, headache, and an eschar (a dark, scab-like lesion) at the bite site. R. parkeri has been detected in Gulf Coast ticks from Florida.8PubMed Central. Gulf Coast ticks (Amblyomma maculatum) and Rickettsia parkeri, United States The American dog tick can carry Rickettsia rickettsii, the agent of Rocky Mountain spotted fever, though confirmed cases from that pathogen are uncommon statewide. Ehrlichiosis, transmitted by the lone star tick, is another bacterial illness on the Florida landscape, producing flu-like symptoms that can become serious if untreated.
Alpha-Gal Syndrome
One of the more unusual risks from lone star tick bites is alpha-gal syndrome, a delayed allergic reaction to a sugar molecule found in red meat and some animal-derived products. Cases cluster heavily in areas where the lone star tick is established, and the geographic pattern closely mirrors that of ehrlichiosis, reinforcing the connection between lone star bites and alpha-gal sensitization.9Morbidity and Mortality Weekly Report. Geographic Distribution of Suspected Alpha-gal Syndrome Cases — United States, January 2017–December 2022 Symptoms typically appear several hours after eating red meat and can include hives, gastrointestinal distress, and in severe cases anaphylaxis. Because the delay between eating and reacting is so long compared to a typical food allergy, alpha-gal syndrome often goes undiagnosed for months or years.
Tick-Borne Relapsing Fever
The soft tick Ornithodoros turicata americanus, found primarily in north Florida, can transmit Borrelia turicatae, the spirochete responsible for tick-borne relapsing fever. The infection rate in surveyed ticks was low (under 1% of pooled samples tested positive), but the disease itself is unpleasant, characterized by recurring bouts of high fever separated by afebrile periods.4PLoS Neglected Tropical Diseases. Prevalence, distribution, and phylogenetics of the tick-borne relapsing fever spirochete Borrelia turicatae in the soft tick Ornithodoros turicata americanus in Florida People most likely to encounter these soft ticks are those spending time around rodent burrows, old structures, or caves.
Why Lyme Disease Is Less Common in the South Despite the Presence of Blacklegged Ticks
This is one of the more fascinating puzzles in tick biology. Blacklegged ticks live in Florida and throughout the Southeast, yet Lyme disease rates are a fraction of what the Northeast sees. The explanation is largely behavioral: southern blacklegged tick nymphs quest differently from their northern counterparts. Research comparing nymphs from different geographic origins found that southern nymphs were far less likely to climb vegetation and wait for passing hosts. Instead, they tended to stay hidden beneath the leaf litter, a behavior researchers have termed “hiding behavior.”10PubMed Central. A comparative evaluation of northern and southern Ixodes scapularis questing height and hiding behaviour in the USA
Northern nymphs from high-risk states were roughly eight times as likely to quest on or above the leaf litter surface compared to southern nymphs. This difference in behavior was strongly correlated with Lyme disease incidence in the nymphs’ counties of origin.11PubMed. Nymphal Ixodes scapularis questing behavior explains geographic variation in Lyme borreliosis risk in the eastern United States A separate experiment confirmed the pattern: nymphs originating from Wisconsin were roughly 4 to 12 times as likely to be observed questing in the open compared to nymphs from southern origins.12PLOS ONE. Different Populations of Blacklegged Tick Nymphs Exhibit Differences in Questing Behavior That Have Implications for Human Lyme Disease Risk
Host ecology also plays a role. The Southeast has a higher abundance of lizards, and blacklegged tick nymphs that feed on lizards are thought to be less likely to acquire or transmit Borrelia burgdorferi. Lizards are among the least-studied hosts in the Lyme cycle, but they appear to participate in feeding ticks without efficiently maintaining the spirochete.13PubMed Central. Lizards and the enzootic cycle of Borrelia burgdorferi sensu lato The combination of nymphs that avoid humans and hosts that dilute pathogen transmission goes a long way toward explaining why Florida’s Lyme numbers are modest despite having the right tick.
Ticks and Your Pets
Dogs in Florida are significantly more likely than cats to come home with ticks. In a statewide veterinary survey, dogs accounted for over 98% of tick submissions. The brown dog tick made up about 94% of ticks found on dogs, which makes sense given that species’ preference for canine hosts and its ability to thrive indoors. On the minority of ticks collected from cats, the lone star tick was the most common species, representing about three-quarters of feline tick submissions.6PubMed. Ticks associated with domestic dogs and cats in Florida, USA
These ticks can transmit diseases to pets as well as to the humans handling them. Brown dog ticks are vectors of canine ehrlichiosis and canine babesiosis. Lone star ticks on cats or dogs can expose family members to all the pathogens that species carries. Year-round tick prevention for pets is especially warranted in Florida given the absence of a reliable hard freeze to knock back tick populations.
Personal Protection That Actually Works
The most effective personal protection against ticks combines treated clothing with a topical repellent. Permethrin-treated clothing provides contact-level killing effects and offers longer-lasting protection against ticks than topical DEET or picaridin alone.14PubMed. Chemical and Plant-Based Insect Repellents: Efficacy, Safety, and Toxicity Field trials showed that permethrin-treated uniforms, whether sprayed or factory-impregnated, reduced tick numbers by 97 to 98% compared to untreated clothing, and this held across lone star ticks, American dog ticks, and blacklegged ticks.15Journal of Medical Entomology. Comparative Field Evaluation of Permethrin and Deet-Treated Military Uniforms for Personal Protection Against Ticks (Acari) DEET applied to clothing alone was still effective, cutting tick numbers by about 60%, but permethrin outperformed it.
For topical skin protection, picaridin, IR3535, and oil of lemon eucalyptus (PMD) may offer better protection than DEET against certain biting arthropods, including ticks, in settings where prolonged exposure is expected.14PubMed. Chemical and Plant-Based Insect Repellents: Efficacy, Safety, and Toxicity In practical terms, any EPA-registered repellent applied to exposed skin, combined with permethrin on your clothing, gives you the best available shield. Tucking pants into socks and wearing light-colored clothing to spot ticks more easily are low-tech additions that genuinely help.
Yard Management and Its Limits
Standard recommendations for reducing ticks on residential property include keeping grass short, removing leaf litter, clearing brush, and creating gravel or mulch barriers between lawn and wooded edges. These steps are sensible and widely recommended, but the evidence that they meaningfully suppress tick numbers on individual properties is thinner than you might assume. A study in Connecticut that evaluated landscaping and vegetation management on residential properties found no statistically significant reduction in blacklegged tick nymph density between managed and unmanaged areas.16Environmental Entomology. Evaluation of landscaping and vegetation management to suppress host-seeking Ixodes scapularis (Ixodida: Ixodidae) nymphs on residential properties in Connecticut, USA
A separate study found that the only yard features significantly associated with higher tick abundance were trash accumulation, stone walls (which harbor rodent hosts), and proximity to forest. Other management variables like mowing frequency and garden maintenance did not have detectable effects on questing tick numbers.17Journal of Medical Entomology. Assessing Effectiveness of Recommended Residential Yard Management Measures Against Ticks This does not mean yard work is pointless. Removing trash and rodent habitat is clearly useful, and reducing the shaded, moist microhabitats ticks prefer should help at the margins. But if you live adjacent to forest or undeveloped land in north Florida, yard management alone is unlikely to eliminate your risk. Personal protection when you step outside remains the more reliable line of defense.
How to Remove a Tick Safely
The best approach is straightforward: grasp the tick as close to the skin as possible with fine-tipped tweezers and pull straight up with steady, even pressure. A systematic review of tick removal methods found limited but supportive evidence in favor of pulling with tweezers or a commercial tick-removal device over twisting or rotating techniques.18PubMed. Effective methods for tick removal: A systematic review Do not use petroleum jelly, nail polish, heat, or any other folk remedy designed to make the tick “back out.” These approaches delay removal and may cause the tick to regurgitate its gut contents into the wound, increasing infection risk.
After removing the tick, clean the bite area with rubbing alcohol or soap and water. If you develop a rash, fever, or flu-like symptoms in the days to weeks following a bite, see a healthcare provider and mention the tick exposure. In Florida specifically, be aware that doctors may not immediately think of tick-borne illness the way a provider in Connecticut or Minnesota would. Being able to describe when and where you were bitten, and what the tick looked like, gives the clinician useful information.
Emerging and Invasive Species on the Horizon
The Asian longhorned tick (Haemaphysalis longicornis), first detected in the United States in 2017, has been expanding its range along the eastern seaboard. Distribution modeling suggests that peninsular Florida falls in a zone of high uncertainty for this species’ potential establishment, meaning it is not yet clear whether the state’s conditions will support a stable population.19Scientific Reports. Potential Spatial Distribution of the Newly Introduced Long-horned Tick, Haemaphysalis longicornis in North America The longhorned tick is concerning because individual females can reproduce without mating, allowing a single introduced tick to establish a population, and because the species has been associated with severe infestations on livestock in other countries.
Climate modeling also points to potential range expansion for cattle fever ticks (Rhipicephalus microplus and R. annulatus), historically associated with a devastating cattle disease that was eradicated from the U.S. through decades of quarantine work along the Texas-Mexico border. Models indicate that by mid-century, climate conditions suitable for these ticks could expand into major cattle-producing areas of the southern United States.20BioMed Central / Parasites & Vectors. Invasive potential of cattle fever ticks in the southern United States For Florida, which has a significant cattle industry, this is not an abstract concern. Any reintroduction of cattle fever ticks would have serious agricultural and economic consequences alongside the public health dimension.
Whether or not these specific species gain a permanent foothold in Florida, the broader trajectory is clear: warming winters and expanding suitable habitat are pushing tick ranges southward and extending the window of activity. For a state that already lacks a reliable winter tick die-off, the practical implication is that the tick problem is more likely to intensify than to recede in the coming decades.
