West Virginia is home to four tick species that bite humans, and the state has seen a dramatic rise in tick-borne illness over the past decade. Reported Lyme disease cases jumped from 297 in 2016 to 1,542 in 2021, making it the most common tick-borne disease in the state. Whether you’re hiking the Appalachian Trail, hunting in the eastern panhandle, or mowing your backyard, knowing which ticks are out there and what they carry helps you protect yourself.
Common Tick Species in West Virginia
Four tick species are tracked by state health authorities: the American dog tick, the blacklegged (deer) tick, the lone star tick, and the Gulf Coast tick. Each looks different, lives in slightly different habitats, and carries different diseases.
The American dog tick is the one you’ll encounter most often. It’s brown to reddish-brown with cream or grayish markings on its back. These ticks are the primary carriers of Rocky Mountain spotted fever in the eastern United States and tend to favor grassy fields, trails, and the edges where lawns meet wooded areas.
The blacklegged tick, also called the deer tick, is the species responsible for Lyme disease. Adults are chocolate brown, and females have a distinctive orange-to-red body surrounding a darker shield on their back. They’re smaller than American dog ticks, roughly the size of a sesame seed in the nymph stage, which is when most transmission to humans occurs. Most human Lyme cases in West Virginia cluster in the eastern panhandle counties of Jefferson, Berkeley, and Morgan, but blacklegged ticks have been found across other parts of the state as well.
The lone star tick is reddish-brown to tan. Females are easy to identify by a single white spot on the center of their back. This species is aggressive. It actively pursues hosts rather than just waiting on vegetation, and its bite is linked to a condition most people haven’t heard of: alpha-gal syndrome, a potentially lifelong allergy to red meat and other mammalian products.
The Gulf Coast tick rounds out the surveillance list. It resembles the American dog tick but has been expanding its range northward into West Virginia in recent years.
The Asian Longhorned Tick
A fifth species, the Asian longhorned tick, has been confirmed in West Virginia counties since its initial U.S. discovery in 2017. This tick is unusual because a single female can reproduce without mating, laying 1,000 to 2,000 eggs at a time. That means hundreds or even thousands of ticks can infest a single animal or a small patch of ground. In other parts of the world, this species transmits several pathogens already present in the U.S., including the bacteria behind Lyme disease, anaplasmosis, ehrlichiosis, and babesiosis. The full impact of its spread is still being studied, but the sheer numbers it produces on livestock and wildlife make it a growing concern for both public health and agriculture.
Tick-Borne Diseases to Know About
Lyme disease dominates the conversation in West Virginia, and for good reason. The five-fold increase in reported cases between 2016 and 2021 reflects both expanding tick populations and greater awareness. Early Lyme disease typically shows up as a circular rash (not always a perfect bull’s-eye) along with flu-like symptoms: fatigue, fever, headache, and muscle aches. Those general symptoms are easy to mistake for a summer cold or virus, which is one reason cases go undiagnosed.
If untreated, Lyme disease progresses. Weeks to months after the bite, it can cause multiple rashes, facial nerve paralysis, heart rhythm problems, and in some cases eye inflammation. Months to years later, the most common lasting feature is arthritis in one or more joints. Neurological problems, though rare at that stage, can also develop.
Alpha-gal syndrome is a different kind of threat. After a lone star tick bite, some people develop an allergic reaction to a sugar molecule found in beef, pork, lamb, and mammalian products like dairy, gelatin, and even leather. Reactions typically appear three to six hours after eating red meat, which makes the connection hard to spot at first. Symptoms range from hives and stomach cramps to full anaphylaxis. West Virginia’s Office of Epidemiology tracks it as a distinct condition because of the state’s large lone star tick population.
Other tick-borne illnesses reported in the state include Rocky Mountain spotted fever (carried by the American dog tick), ehrlichiosis, anaplasmosis, and babesiosis. All can cause fever, headache, and fatigue in their early stages, making it important to mention any recent tick exposure when visiting a healthcare provider.
When Ticks Are Most Active
Tick activity in West Virginia ramps up in spring and stays high through summer, with a secondary bump in fall for adult blacklegged ticks. The highest risk period for Lyme disease runs roughly from April through September, which overlaps with when the tiny nymphal-stage deer ticks are feeding. Nymphs are so small (about the size of a poppy seed) that many people never notice the bite.
Adult ticks are active from early spring into late fall, and blacklegged adults can remain active on mild winter days when temperatures climb above freezing. If you’re a deer hunter in November, you’re still at risk. American dog ticks and lone star ticks are most active from April through August.
Where Risk Is Highest
The eastern panhandle, particularly Jefferson, Berkeley, and Morgan counties, consistently reports the most Lyme disease cases. But the state’s surveillance data shows confirmed or probable cases in most West Virginia counties between 2000 and 2014, so no region is truly tick-free. Wooded areas, leaf litter, tall grass, and the brushy edges between forest and open land are the habitats where encounters happen most. Ticks also thrive along stream banks, stone walls, and anywhere deer and rodents travel regularly.
Protecting Yourself
Permethrin-treated clothing is one of the most effective barriers. You can buy pre-treated gear or spray your own boots, pants, and socks with a permethrin product. On skin, EPA-registered repellents containing DEET, picaridin, or oil of lemon eucalyptus all reduce tick bites. Tucking pants into socks looks ridiculous and works well.
The single most important habit is a thorough tick check after spending time outdoors. Ticks prefer warm, hidden areas: behind the ears, along the hairline, in the armpits, behind the knees, and around the waistband. Showering within two hours of coming inside helps wash off unattached ticks and gives you a natural opportunity to check your skin. Running clothes through a hot dryer for 10 minutes kills ticks even if the clothes are dry.
If you find an attached tick, remove it with fine-tipped tweezers by grasping as close to the skin as possible and pulling straight up with steady pressure. Don’t twist, squeeze the body, or use petroleum jelly or a hot match. Clean the bite area with rubbing alcohol or soap and water.
After a Tick Bite
Not every tick bite requires antibiotics. Current guidelines recommend preventive treatment only for bites that meet specific high-risk criteria: the tick was identified as a blacklegged tick, it was attached long enough to have fed (typically 36 hours or more), and the bite occurred in an area where Lyme disease is common. If those criteria are met and you seek care within 72 hours of removing the tick, a single dose of an antibiotic can reduce your risk of developing Lyme disease.
For bites that don’t meet those criteria, or where the tick species is unknown, observation is the standard recommendation. Watch the bite site for a rash and monitor yourself for fever, fatigue, headache, or joint pain over the following 30 days. Early Lyme symptoms can appear anywhere from 3 to 30 days after the bite.
Tick Identification Services
West Virginia’s Zoonotic Disease Program offers tick identification through veterinary practices as part of the state’s surveillance efforts. Ticks should be killed by drowning in alcohol, then sealed in a watertight container (a zip-lock bag with an alcohol-soaked cotton ball works) to prevent the specimen from drying out. Submissions go to the Office of Laboratory Services in South Charleston. This service identifies the species for surveillance purposes, not as a diagnostic test for disease. For questions about tick-borne disease surveillance, the Zoonotic Disease Program can be reached at (304) 558-5358 ext. 1.
