Lone star ticks are the most common tick species encountered by people in Georgia, found across nearly every region of the state except the mountainous Blue Ridge area in the northeast corner. They’re aggressive biters, active for much of the year in Georgia’s warm climate, and capable of transmitting several serious diseases, including one that can trigger a lifelong allergy to red meat.
Where They Live in Georgia
A 2022 survey of 198 locations across 43 Georgia state parks and wildlife management areas found lone star ticks in every ecoregion except the Blue Ridge mountains. The heaviest concentrations were in forested areas of the Piedmont, Southeastern Plains, and Southern Coastal Plains, which together cover the vast majority of the state. If you spend time outdoors anywhere from metro Atlanta southward, you’re in prime lone star tick territory.
These ticks thrive in very specific conditions: forested areas at mid-elevation with soils that hold moisture but aren’t waterlogged. Brushy bottomlands near creeks and rivers are especially productive habitat, particularly where deer are common. Game trails, thick undergrowth, and leaf litter all concentrate tick populations. Large deer herds correlate directly with large tick populations, since deer are a primary host for adult lone star ticks.
When They’re Most Active
Lone star ticks are active in Georgia from early spring through midsummer, with the highest risk falling roughly March through July. Georgia’s warm, humid climate can extend this window in either direction during mild years. Adults and nymphs (the immature stage most likely to bite people) overlap in their active seasons, meaning you can encounter multiple life stages on a single outing. Nymphs are particularly easy to miss because they’re roughly the size of a poppy seed.
How to Identify Them
Adult female lone star ticks are the easiest to recognize. They’re reddish-brown and have a single bright white or silvery spot in the center of their back, which gives the species its name. Males are smaller, lack the prominent white dot, and instead have scattered white streaks or spots along the edges of their body. Both sexes have notably long mouthparts compared to other common ticks, and they’re rounder in shape than the flatter black-legged (deer) tick. Nymphs and larvae are tiny, pale tan, and lack the distinctive markings of adults.
Diseases Lone Star Ticks Carry
Lone star ticks transmit a wider range of pathogens than most people realize. The diseases linked to their bites include ehrlichiosis, southern tick-associated rash illness (STARI), tularemia, heartland virus disease, bourbon virus disease, and alpha-gal syndrome. Georgia’s Department of Public Health recorded 32 confirmed cases of ehrlichiosis alone between 2018 and 2022, though actual numbers are likely higher since surveillance depends on doctors reporting cases.
Ehrlichiosis causes fever, headache, muscle aches, and fatigue, typically appearing one to two weeks after a bite. It can become severe if untreated. STARI produces a circular rash that looks similar to the bull’s-eye rash of Lyme disease, along with fatigue and body aches. Researchers still don’t know what pathogen causes STARI, which makes it one of the more puzzling tick-borne conditions. Notably, lone star ticks are not considered a significant vector for Lyme disease itself.
Alpha-Gal Syndrome
Perhaps the most unusual condition tied to lone star ticks is alpha-gal syndrome, sometimes called “red meat allergy.” When a lone star tick bites you, it can inject a sugar molecule called alpha-gal into your bloodstream. Your immune system may then begin producing antibodies against that molecule. Because alpha-gal is naturally present in beef, pork, lamb, and other mammalian meats, eating those foods can trigger an allergic reaction.
What makes alpha-gal syndrome tricky to diagnose is the delay. Reactions typically appear two to six hours after eating, which is far longer than most food allergies. Symptoms range from hives, stomach pain, and nausea to severe anaphylaxis with throat swelling, rapid pulse, and difficulty breathing. Some people develop the allergy after a single tick bite, while others are bitten repeatedly without issue. Researchers still don’t fully understand why some people react and others don’t. Because of the delayed timing, some people with alpha-gal syndrome experience repeated unexplained allergic episodes before anyone connects the dots to their diet.
Preventing Bites
Lone star ticks are ambush predators. Unlike black-legged ticks, which wait passively on vegetation, lone star ticks actively move toward hosts when they detect carbon dioxide or movement. This makes them more likely to find you even if you stay on trails. Prevention requires a layered approach.
For skin, repellents containing 20% to 35% DEET provide effective protection. Concentrations above 30% don’t repel ticks any better but do last longer. Products with 20% picaridin offer 8 to 14 hours of protection and are a good alternative for people who prefer to avoid DEET. For children over two months old, 10% to 30% DEET is considered safe.
For clothing and gear, permethrin is the gold standard. You can buy 0.5% permethrin spray at most pharmacies or outdoor retailers and treat your own pants, socks, shoes, and packs. Permethrin kills ticks on contact and remains effective through several washes. Wearing treated clothing in combination with a skin repellent provides the strongest protection available.
Behavioral habits matter just as much as chemicals. Stay in the center of trails rather than brushing against vegetation at the edges. Avoid leaf litter, tall grass, and brushy areas, especially near bottomlands and creeks where tick density is highest. After time outdoors, do a thorough tick check focusing on the hairline, ears, underarms, waistband, and behind the knees. Showering within two hours of coming indoors helps wash off ticks that haven’t attached yet. Tossing clothes in a hot dryer for 10 minutes kills any ticks hiding in fabric.
Removing an Attached Tick
If you find a lone star tick attached to your skin, use fine-tipped tweezers to grasp it as close to the skin surface as possible. Pull upward with steady, even pressure. Don’t twist, jerk, or squeeze the body, as this can leave mouthparts embedded or push saliva into the bite. Clean the area with rubbing alcohol or soap and water afterward. Save the tick in a sealed bag or take a photo, which can help with identification if you develop symptoms later. Watch the bite site for several weeks for any rash, and pay attention to fever, headache, or unusual fatigue, all of which warrant a call to your doctor.
