Yes, South Florida has ticks. What it does not have is the tick most national articles are actually written about.
The black-legged tick that drives Lyme disease coverage across the Northeast is present in Florida at low densities, and Lyme is uncommon here. The species you are more likely to encounter in Palm Beach County, Martin County, or St. Lucie County are different animals with a different risk profile.
That distinction matters because it changes what you should be watching for and where.
What to know first
Several tick species are established across Florida. UF/IFAS documents the Lone Star tick as established throughout the state in wooded, brushy, and transitional habitat, and it is the species most commonly encountered by people here.
Lyme disease risk is low. The Florida Department of Health tracks a small number of confirmed cases annually, many of them travel-associated rather than acquired in state.
The tick most often found inside Florida homes is the brown dog tick, which can complete its entire life cycle indoors and does not need a yard at all.
Peak encounter season runs March through September, though the absence of a hard winter means ticks remain possible in every month.
Four are worth knowing by name.
Lone Star tick.
The one you are most likely to encounter outdoors. Adult females carry a single white dot on the back, which is where the name comes from. Aggressive feeders that actively move toward hosts rather than waiting passively, and all three life stages will bite people. This is also the species associated with alpha-gal syndrome, a red meat allergy triggered by a tick bite.
Brown dog tick.
The one that shows up indoors. Adapted to living with dogs and inside human structures, and capable of completing its full life cycle in a house with no yard. Homeowners find them along baseboards, in wall cracks, behind furniture, and around dog bedding, often in rooms with no obvious outdoor connection.
Gulf Coast tick.
Common in coastal and grassy areas of Florida. Adults typically feed on larger animals including deer and cattle, while immature stages feed on birds and small mammals. Less frequently encountered on people than the Lone Star tick, though present across the region.
Black-legged tick.
The Lyme disease vector, present in Florida at considerably lower densities than in the Northeast, and with lower infection rates within the tick population. Its presence is the reason Lyme cannot be ruled out entirely here, but the risk is not comparable to Connecticut or Pennsylvania.
Ticks need shade, humidity at ground level, something to climb, and hosts passing through. Trees are only one way to get the first two.
Properties bordering preserved or conservation land see the most pressure, though the mechanism is wildlife movement rather than the trees themselves. Wellington, Loxahatchee, western Boynton Beach, and properties along the Savannas Preserve all fall into that category.
Within a property, ticks concentrate in transitional zones rather than open lawn. Shaded ground cover, the interior of hedges, mulch beds on the north or east side of the house, fence line edges where leaf litter accumulates, and wherever a dog rests outside. Our guide on tick habitat in suburban yards covers this in detail, including why mowed turf is poor tick habitat.
Hosts matter more than habitat type. A dog with outdoor access is the strongest single factor in a residential setting, followed by outdoor cats and the raccoons and opossums that cross nearly every South Florida property at night.
Worth being specific rather than alarming.
Alpha-gal syndrome.
A Lone Star tick bite can trigger an allergy to mammalian meat. CDC estimates as many as 450,000 Americans may be affected, with more than 110,000 suspected cases identified from 2010 through 2022. Reactions appear two to six hours after eating red meat, which makes the connection to the bite difficult to identify. Our guide on alpha-gal covers the honest geographic picture, including why Florida is not among the highest-prevalence states.
Rocky Mountain spotted fever and ehrlichiosis.
Both are tick-borne bacterial illnesses documented in the southeastern United States. Florida reports cases annually, and both are treatable with prompt medical attention.
Lyme disease.
Present but uncommon, and many Florida cases are travel-associated.
Nothing at all, most of the time.
Most tick bites transmit nothing. That is not a reason to ignore them, but it is worth knowing before assuming the worst. If you have a bite that is worsening, spreading, or accompanied by fever, that is a question for a physician rather than a pest control company.
Most tick content published in the United States is written about the Northeast and Upper Midwest, where black-legged ticks dominate, deer populations drive the cycle, and forested habitat with deep leaf litter is the primary concern.
Apply that framework to a Wellington property and you reach the wrong conclusions. You would be watching for the wrong species, looking in the wrong habitat, and weighting Lyme disease far above the risks that actually apply here.
Two Florida-specific realities that national articles miss. The brown dog tick can infest a house independently of any yard, which no northeastern guide addresses. And the absence of a hard winter means veterinary tick prevention on pets matters year-round rather than seasonally.
Habitat modification does most of the work.
Keep grass mowed, especially the edges and corners a mower usually skips. Thin dense ground cover in shaded areas where people and pets spend time. Trim shrubs so air moves through and the base is visible, which lowers humidity in the interior. Reduce mulch depth in shaded beds. Clear leaf accumulation along fence lines. Create a gravel or hardscape break between lawn and any brushy edge.
Keep pets on veterinary tick prevention year-round, and check dogs after they have been in landscape beds or tall grass, focusing on ears, neck, armpits, and between toes.
Secure trash and remove fallen fruit to reduce the wildlife traffic that carries ticks onto the property in the first place.
Professional yard treatment targets the transitional zones where ticks concentrate rather than broadcasting across open lawn. Combined with habitat modification and veterinary prevention, that is what changes the outcome. UF/IFAS integrated pest management guidance emphasizes addressing the conditions supporting a population alongside treatment, and with ticks the habitat side carries more weight than usual.
Occasional ticks on a dog after a walk in a park or preserve is not a yard problem.
Repeated ticks on pets that only use your own yard indicates an established property population.
Ticks found indoors, particularly along baseboards or walls, points toward brown dog tick and warrants prompt attention, since indoor populations grow rather than resolving.
Properties adjacent to preserve land often need seasonal treatment regardless of how well the habitat is managed, because the source is off the property.
If ticks keep turning up on pets that only use your own yard, the source is on the property and worth locating. Wise House Pest Control offers a free inspection across Palm Beach County, Martin County, and St. Lucie County.
