Tick Season in South Carolina: What to Know and How to Stay Safe
March 30, 2026
South Carolina’s warm climate and lush outdoor landscapes make it a wonderful place to hike, hunt, and explore — but they also create ideal conditions for one of the state’s most persistent health concerns: ticks. Unlike states with hard winters that push tick activity into a short seasonal window, South Carolina residents face tick exposure nearly every month of the year.
Whether you’re spending time in the Lowcountry marshes, the Upstate forests, or simply walking your dog in the backyard, understanding tick season in South Carolina can help you make smarter decisions outdoors and respond quickly if a bite occurs. This guide covers when ticks are active, which species you’ll encounter, the diseases they carry, and exactly what to do if one latches on.
When Is Tick Season in South Carolina
Warm weather in South Carolina means that ticks can be active year-round, despite many people letting their guard down in the fall and winter. This is one of the most important things to understand about ticks in the Palmetto State — there is no true “off season.”
Ticks are always in season due to the life cycles of different species overlapping. That said, activity does intensify during warmer months. February’s first warm days bring ticks out from winter dormancy. By March, nymphs actively search for blood meals in your yard. Adult ticks stay active through November, giving these disease-carriers nearly ten months to threaten your family and pets.
South Carolina’s mild winters create year-round tick activity during warm spells. Blacklegged ticks stay active when temperatures climb above 35 degrees. Lone star ticks emerge earlier than other species, often appearing in late February. American dog ticks peak from April through July but remain active into fall. Tick season intensifies from April through September when all three major species hunt simultaneously.
Key Insight: Peak tick season in South Carolina runs from April through September, but you should remain vigilant from late winter through late fall — and even during mild winter days.
If you enjoy outdoor activities like dove hunting in South Carolina, keep in mind that your time afield during late summer and early fall places you squarely in peak tick season. Taking precautions before and after every outing is essential.
Types of Ticks Found in South Carolina
In South Carolina, people often encounter six tick species: the blacklegged, lone star, American dog, brown dog, Gulf Coast, and Asian longhorned ticks. Each species has distinct habits, preferred hosts, and associated health risks. Knowing how to identify them can help you assess your risk after a potential bite.
| Tick Species | Key Identifier | Primary Hosts | Main Disease Risk |
|---|---|---|---|
| Lone Star Tick | White dot on female’s back | Deer, humans, dogs | Ehrlichiosis, STARI, alpha-gal allergy |
| Blacklegged (Deer) Tick | Dark legs, small size | Deer, mice, humans | Lyme disease, anaplasmosis |
| American Dog Tick | White markings on back | Dogs, rodents, humans | Rocky Mountain spotted fever, tularemia |
| Brown Dog Tick | Reddish-brown, uniform color | Primarily dogs | Rocky Mountain spotted fever (in dogs) |
| Gulf Coast Tick | Ornate markings | Birds, deer, humans | Rickettsia parkeri rickettsiosis |
| Asian Longhorned Tick | No white dot, smaller size | Livestock, dogs, humans | Emerging — under active surveillance |
The lone star tick is the most collected species in South Carolina. This tick can cause alpha-gal allergy (red meat allergy), ehrlichiosis, and Southern Tick-Associated Rash Illness. It is easy to recognize — it sports a white dot on its back, which is one of the reasons for its “Lone Star” name.
The blacklegged tick is found across South Carolina, but in low volume. This tick can transmit Lyme disease, tick-borne relapsing fever, and anaplasmosis. The American dog tick can also be found in South Carolina and can transmit Rocky Mountain Spotted Fever.
The brown dog tick is a particular threat to homes in South Carolina because it is able to live entirely inside a home. From egg to adult, it is right at home in the bedding of your pet, in your carpet, and in many other locations. While this tick is mostly a threat to pets, it can also be a threat to humans through the spread of Rocky Mountain spotted fever.
The Asian longhorned tick deserves special attention as an invasive species of growing concern. It was first identified in the United States from a sample taken off a white-tailed deer in 2010 in West Virginia, and was first identified in South Carolina in Pickens and Lancaster Counties on dogs in an animal shelter in 2020. These ticks are of great concern as females can replicate quickly without males, a process called parthenogenesis, and can infest the environment in a short time. To learn more about how ticks reproduce, visit our guide on how ticks reproduce.
Important Note: The Asian longhorned tick can produce 1,000 to 2,000 eggs at a time without mating, making infestations capable of growing rapidly in a short period.
Tick-Borne Diseases in South Carolina
Ticks can carry and transmit a multitude of pathogens that may result in contracting a tick-borne disease, including anaplasmosis, babesiosis, Lyme disease, Rickettsia parkeri rickettsiosis, Rocky Mountain spotted fever, Southern Tick-Associated Rash Illness (STARI), ehrlichiosis, Powassan virus disease, Heartland virus, and tularemia.
In the central and southeastern U.S., ehrlichiosis and spotted fever rickettsiosis are top concerns, along with a tick-induced allergy to red meat. Here is a closer look at the most significant diseases South Carolinians should know about:
Lyme Disease: Lyme disease is caused by Borrelia bacteria that is transmitted after a tick has been attached and feeding for 24–72 hours. Symptoms begin within days or weeks after a tick bite and may include fever, headache, chill, stiff neck, fatigue, muscle aches, and joint pain. An expanding red skin rash called erythema migrans (EM), which grows at the site of the tick bite, occurs in 70–90% of patients.
Rocky Mountain Spotted Fever (RMSF): Despite its name, RMSF is a serious concern in the Southeast. It is transmitted primarily by the American dog tick and brown dog tick in South Carolina and can cause severe illness if not treated promptly with antibiotics.
Ehrlichiosis: Spread mainly by the lone star tick, ehrlichiosis causes fever, headache, chills, and muscle aches. Symptoms typically appear within one to two weeks of a bite.
Heartland Virus: Heartland virus disease is caused by a virus in the genus Bandavirus. Symptoms begin within a few days to two weeks after a tick bite and may include fever, fatigue, decreased appetite, headache, nausea, diarrhea, and muscle or joint pain.
Powassan Virus: Powassan virus disease is caused by Powassan virus or deer tick virus. Initial symptoms begin within one week to one month after a tick bite and may include fever, headache, vomiting, and weakness. Powassan virus can cause severe disease, including inflammation of the brain (encephalitis) or the membranes around the brain and spinal cord (meningitis). For more detail on encephalitis caused by tick-borne viruses, see our article on tick-borne encephalitis.
Alpha-Gal Syndrome (Red Meat Allergy): A circular rash of unknown cause (STARI) sometimes follows the bite of the lone star tick, and growing evidence suggests that alpha-gal syndrome (red meat allergy) may be triggered by the bite of lone star ticks.
In addition to tick-borne diseases, a toxin can be transmitted through the saliva of a tick bite that causes progressive paralysis, a condition known as “tick paralysis.” Tick feeding may also result in mild to severe allergic reactions in some individuals.
Pro Tip: Disease transmission from ticks generally occurs within 24 to 72 hours after attachment — but Powassan virus can be transmitted in as little as 15 minutes. Removing ticks as soon as possible after discovery is always the right move.
High-Risk Areas and Habitats in South Carolina
Ticks are generally found near the ground in forests and in areas with brush or tall grass and weeds. They cannot jump or fly. Instead, they climb tall grasses or shrubs and wait for a potential host to brush against them. This behavior is known as “questing” and is how the vast majority of tick encounters happen.
In South Carolina, several environments carry elevated tick risk:
- Coastal forests and maritime shrublands — Particularly in the Lowcountry, where warm temperatures and high humidity create ideal tick habitat year-round
- Upstate woodlands and mountain foothills — Forested areas in counties like Pickens, Greenville, and Oconee are known habitats for blacklegged ticks
- Marshes and grassy wetlands — The Gulf Coast tick thrives in coastal plain environments
- Suburban backyards with wooded edges — The transition zone between lawn and forest is one of the highest-risk areas for tick encounters
- Livestock and agricultural areas — Cattle farms and pastures, as demonstrated by the York County Asian longhorned tick infestation, can harbor high tick densities
- Hiking trails and parks — Overgrown vegetation along trail edges is a common questing site
Pasture and lawn control measures — such as maintaining low grass height, controlling weeds and other brushy areas, and removing woody debris from pasture and lawn edges — can reduce tick-bite risk. Maintaining a 9-foot distance between pasture or lawn and wooded edge habitat can reduce the risk of tick contact.
Common Mistake: Many people assume ticks are only found deep in the woods. In reality, your own backyard — especially if it borders trees or tall grass — can be just as risky during peak season.
South Carolina’s diverse wildlife also contributes to tick distribution. Many animals serve as hosts that carry ticks across the landscape. You can learn more about the wildlife in South Carolina’s ecosystems, including species like snakes, salamanders, and bats — many of which interact with tick populations. In fact, some animals are natural predators of ticks, and you can read about animals that eat ticks and help keep local populations in check.
How to Protect Yourself, Children and Pets During Tick Season in South Carolina
Protection starts before you head outdoors. A few consistent habits can dramatically reduce your risk of tick bites and tick-borne illness throughout the year.
Personal Protection
Use EPA-registered insect repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol, or 2-undecanone. Treat clothing and gear, such as boots, pants, socks, and tents with products containing 0.5% permethrin.
Wear light-colored clothing so that, if a tick does hitch a ride on you, it will be easy to spot. Wear long-sleeved shirts, long pants and hats, and tuck pants into socks or shoes. When hiking, try to stay on the cleared pathways of the trail and avoid exploring areas with overgrown brush, shrubbery, or grass.
After Time Outdoors
Showering when you come in from outside has been shown to be a good way to prevent tick-borne diseases. Ideally, that would be within two hours. It helps to either wash off ticks that haven’t become attached, or makes you more apt to find ticks that may be on you because you can do a full body tick check.
Experts say 15 minutes in a dryer on high heat is enough to kill any remaining ticks on clothing.
Perform a full-body tick check, paying close attention to these areas:
- Under the arms
- In and around the ears
- Inside the belly button
- Behind the knees
- Between the legs
- Around the waist
- Along the hairline and scalp
Protecting Children
Children are particularly vulnerable to tick bites because they often play in grassy or wooded areas. Apply repellents according to label directions before outdoor play, dress them in protective clothing, and perform a head-to-toe tick check every day during active tick season. It’s good guidance for parents to keep an eye out for their kids. Once traveling through tick-prone areas, always do a daily tick check.
Protecting Pets
Veterinarians and other pet care experts highly recommend a preventative treatment program to help your pet avoid fleas and ticks. There are a variety of options for you to choose from including medicated collars, oral pills, and more.
Symptoms pets may exhibit after being bitten by a tick include fatigue, lameness, fever and loss of appetite. Seek veterinary care if a pet shows any of these symptoms. South Carolina companion animal and livestock owners are encouraged to work with their veterinarian to determine an appropriate tick prevention and treatment program for their animals.

You should also be aware that South Carolina is home to a variety of insects and other creatures that share the same outdoor environments — from bees and ants to flies — and general outdoor awareness goes a long way.
Yard and Property Management
Cutting grass short and removing leaves from your yard helps keep ticks away. Create a buffer zone of wood chips or gravel between your lawn and wooded areas to discourage tick migration. Keep woodpiles away from the house, and consider limiting wildlife access to your yard, as deer and rodents are primary tick hosts.
Pro Tip: Treating your yard with permethrin-based products in early spring — before peak tick season — can significantly reduce tick populations around your home before they build up.
What to Do If You Find a Tick in South Carolina
Staying calm and acting quickly are the two most important things you can do when you find an attached tick. The sooner you remove it, the lower your risk of disease transmission.
How to Remove a Tick Safely
- Use fine-tipped tweezers. Grasp the tick as close to the skin’s surface as possible. Pull upward with steady, even pressure while being careful not to jerk or twist the tick, as this could cause the mouthparts to break off and remain in the skin.
- Clean the bite area. After removal, clean the bite area with soap and water and apply an antiseptic such as iodine, hydrogen peroxide, or rubbing alcohol.
- Note the date. Write down the date of the tick bite to help monitor for potential symptoms.
- Consider saving the tick. To be safe, consider saving the tick after removal should any symptoms develop later. Put it in a sealed bag or container, write the date and location where bitten, and keep the sealed bag or container in the freezer.
What NOT to Do
When removing a tick, avoid covering it in nail polish and don’t try to suffocate it with Vaseline. These techniques could cause the tick to release fluid that increases the chance of tick-borne disease transmission. You should also never burn the tick or use petroleum-based products on it while it is still attached.
Important Note: If the tick’s mouthparts break off and remain in the skin, do not dig at the skin to remove them. Clean the area and allow it to heal. Seek medical attention if the area becomes infected.
When to See a Doctor
Seek medical attention promptly if:
- The tick cannot be fully removed
- The tick was on the person for more than 36 hours, especially in areas known for Lyme disease
- You develop symptoms such as fever, rash, muscle aches, or joint pain within 30 days of the bite
- A bull’s-eye rash appears around the bite site
Disease transmission from ticks generally occurs within 24 hours or up to 72 hours after attachment, but diseases such as Powassan virus disease can be transmitted in as little as 15 minutes. In general, the longer a tick is attached, the more likely it is to pass on an infection if it is carrying one.
Reporting Tick Bites and Tick-Borne Illness in South Carolina
South Carolina has an active tick surveillance program, and your participation can help protect the broader community. Reporting tick encounters and submitting collected ticks contributes to statewide data that shapes public health responses.
Report Tick-Borne Illness
If you are diagnosed with a tick-borne illness, your healthcare provider is required to report it to the South Carolina Department of Public Health (DPH). You can also contact the DPH Vector-Borne Diseases Division directly at Vector@dhec.sc.gov or by calling 803-896-3802.
Submit Ticks for Identification
With an increase in tick species and tick-borne disease awareness in South Carolina, the DPH Vector-Borne Diseases Division is partnering with the University of South Carolina and Clemson University Livestock and Poultry Health to collect ticks from domestic animals and livestock. This surveillance will help determine tick species presence, prevalence, distribution, seasonality, and potential tick-borne disease risks.
To participate in the tick surveillance project, send collected ticks in any sealable vial or zippered storage bag to: The Laboratory of Vector-borne and Zoonotic Diseases, 915 Greene Street #327, Columbia, SC 29201, OR the S.C. Department of Public Health, ATTN: Medical Entomology (State Park Bldg 5), P.O. Box 2046, West Columbia, SC 29171.
When submitting a tick, include:
- Your name and contact information
- The date and location where the tick was collected
- Whether the tick was removed from a person, pet, or livestock
- Any symptoms experienced after the bite
Key Insight: Submitting ticks — especially unfamiliar species — helps South Carolina researchers track the spread of invasive species like the Asian longhorned tick and identify emerging disease risks before they become widespread health threats.
