Tick bites in South Florida: the red meat allergy nobody expects and what homeowners need to know

Have you been following the tick news this spring? ER visits for tick bites across the country hit their highest levels since 2017 in April, according to the CDC. One species in particular is driving a wave of media coverage for a reason most people find hard to believe. A single bite from a Lone Star tick can trigger alpha-gal syndrome, a lifelong allergic reaction to red meat. Up to 450,000 Americans may already have the condition, and most of them were diagnosed years after the bite because symptoms do not appear until hours after eating beef, pork, or lamb. Here in Palm Beach County and the Treasure Coast, the Lone Star tick is established and active right now during peak breeding season. Most South Florida homeowners have never considered ticks a priority. The 2026 data says that should change.

The fast version

Alpha-gal syndrome (AGS) is an allergic reaction to a sugar molecule found in most mammalian meat, including beef, pork, and lamb. A Lone Star tick bite introduces alpha-gal into the bloodstream, triggering the immune response. The CDC estimates as many as 450,000 Americans may be affected by alpha-gal syndrome, with more than 110,000 suspected cases identified from 2010 through 2022. The true number is unknown because AGS is not a nationally notifiable condition. The highest case concentrations are in the South, Midwest, and Mid-Atlantic states, particularly Oklahoma, Arkansas, Missouri, Tennessee, Kentucky, Virginia, and North Carolina. CDC’s prevalence mapping does not list Florida among the highest-concentration states. However, the Lone Star tick that causes AGS is established across Florida, and the risk is real for homeowners in areas where the tick is active. Lyme disease is a separate tick-borne concern. Florida’s risk is lower than the Northeast, but black-legged ticks are present at low densities. Tick prevention on residential properties reduces exposure to both alpha-gal and Lyme disease risk simultaneously.

What alpha-gal syndrome actually is

Alpha-gal is a sugar molecule present in the meat and byproducts of most mammals. Humans do not naturally produce it. When a Lone Star tick introduces alpha-gal during a bite, the immune system can develop antibodies that trigger an allergic reaction the next time the person eats mammalian meat.

The key difference from other food allergies is timing. Traditional food allergies produce symptoms within minutes. Alpha-gal reactions are delayed two to six hours after eating red meat.

A patient who eats steak at 7pm and develops hives at 1am rarely connects the two events without medical guidance. Severity ranges from mild skin reactions to full anaphylaxis. Some patients react only to meat. Others react to dairy, gelatin-based medications, and other mammalian-derived products. There is no cure, and for many patients, the condition is lifelong.

Where alpha-gal syndrome is most concentrated

AGS is not evenly distributed across the country. CDC’s geographic analysis identifies the highest prevalence in a contiguous belt across the South, Midwest, and Mid-Atlantic, with the top states including Oklahoma, Kansas, Arkansas, Missouri, Mississippi, Tennessee, Kentucky, Illinois, Indiana, North Carolina, Virginia, Maryland, and Delaware.
Florida is not listed among the highest-prevalence states in the CDC data. That does not mean the risk is zero here. The Lone Star tick is established across the broader Southeast, and CDC’s 2026 Lone Star tick distribution map includes established populations through 2025. Cases have been reported in Florida, though at lower rates than the core hotspot states.

April 2026 reporting from WUSF confirmed that alpha-gal awareness and reporting requirements are expanding, with Massachusetts joining states mandating reports and preliminary research showing a dramatic rise in positive alpha-gal antibody tests nationally from 2013 through 2024.

The honest framing for South Florida homeowners is this: alpha-gal syndrome is most concentrated in states north and west of Florida, but the tick species that causes it is present here, encounters happen here, and the consequences of a single bite are serious enough that prevention is worth taking seriously.

The national tick surge in 2026

The alpha-gal conversation is happening against a backdrop of elevated tick activity nationally. As of April 2026, CDC data shows emergency room visits for tick bites are higher than normal across most U.S. regions, with weekly ER visit rates the highest for that time of year since 2017 in all regions except the South Central United States.
CDC also estimates approximately 31 million tick bites occur annually in the United States, with about 476,000 Lyme disease patients treated each year. The 2026 data suggests this year’s tick season is tracking above the recent baseline.
For South Florida, the practical implication is that tick awareness matters more this season than usual, even in a state where tick-borne disease rates are lower than the national hotspots.

The Lone Star tick in South Florida

UF/IFAS documents the Lone Star tick as established throughout Florida, with populations concentrated in wooded, brushy, and transitional habitat areas. Palm Beach County and the Treasure Coast support active populations, particularly in western communities near preserve land and the wooded corridors along the Loxahatchee River, Hungryland Slough, and the Savannas Preserve.


Lone Star ticks are aggressive feeders that actively move toward hosts in response to carbon dioxide, body heat, and movement. All three life stages bite humans. The adult female is identifiable by a distinctive white dot on her back.
Peak activity in South Florida runs March through September, with the highest encounter rates in May and June.

Lyme disease risk in Florida

Lyme disease is caused by Borrelia burgdorferi, transmitted by the black-legged tick. The Florida Department of Health tracks a small number of confirmed Lyme cases annually, many associated with travel to endemic northeastern states rather than local transmission.


The risk in South Florida is lower than the Northeast but not zero. Black-legged ticks are present at low densities, and infection rates within the tick population are lower. Tick prevention on your property reduces exposure to both Lyme and alpha-gal risk simultaneously, which is why the prevention steps matter even in a state where Lyme is uncommon.

Where ticks live on South Florida properties

Ticks concentrate in transitional zones between maintained lawn and wooded or brushy areas. Tall grass, leaf litter, mulch beds adjacent to wooded areas, and the edges of trails and preserves are the highest-risk zones.

In Palm Beach County and the Treasure Coast, the highest residential tick exposure occurs in western communities near preserved land. Wellington, Loxahatchee, western Boynton Beach, western Port St. Lucie, and properties adjacent to the Savannas Preserve all see consistent activity. Pets, particularly dogs walking through tall grass and wooded trails, are the most common carriers of ticks onto residential property.

How to reduce tick exposure on your property

Shield Icon

Maintain a clear boundary between lawn and wooded areas.

Mow regularly, keep grass short, and create a three-foot gravel or mulch barrier between the lawn edge and any wooded or brushy zone.

Shield Icon

Remove leaf litter and brush piles.

Ticks thrive in moist, shaded conditions under accumulated debris near tree lines.

Shield Icon

Check pets after outdoor activity.

Dogs pick up ticks from tall grass and bring them onto the property. Regular tick checks and veterinary tick prevention reduce the transfer.

Shield Icon

Professional tick treatment.

Yard and perimeter treatment targeting transitional zones where ticks concentrate reduces the population through peak activity season. Most effective when combined with habitat modification.
