Kansas is home to four main tick species, and at least one of them is active during nearly every month of the year. The lone star tick is the most abundant tick in the state and transmits the majority of tick-borne diseases reported here. In 2024 alone, the Kansas Department of Health and Environment received over 200 laboratory reports of tick-borne illness before the end of May, including hospitalizations and one fatality. Knowing which ticks live here, when they’re active, and how to protect yourself makes a real difference.
Four Tick Species to Know
Each of the four common Kansas ticks has its own preferred habitat, activity window, and disease risk.
The lone star tick is the one you’re most likely to encounter. It’s found across most of the state, especially in the eastern half, and stays active from early spring through late fall. Adults and nymphs show up earlier in the season, while the tiny larvae (sometimes called “seed ticks”) become common later in summer and into fall. Lone star ticks are aggressive biters and the primary carriers of most tick-borne diseases in Kansas.
The American dog tick is most active during spring and summer. Both nymphs and adults are common during these months, and they tend to frequent grassy areas, trails, and places where dogs and wildlife pass through regularly.
The blacklegged tick (also called the deer tick) breaks the pattern. It’s most active during fall and spring when temperatures are cooler, and adults remain active through the winter on days when the temperature rises above freezing and snow cover is light. This means you can pick up a blacklegged tick in December or January, a time when most people aren’t thinking about ticks at all.
The Gulf Coast tick prefers drier prairie grassland, which makes it well suited to western and central Kansas. It’s active during the hottest stretch of the year, from April through October.
Tick Season Runs Nearly Year-Round
There’s no single “tick season” in Kansas. Lone star ticks cover early spring through late fall. Gulf Coast ticks peak in summer heat. American dog ticks are a spring and summer concern. And blacklegged ticks fill in the gaps during fall, winter, and early spring. The only time tick risk drops significantly is during sustained freezing temperatures with snow on the ground.
Peak risk for most people runs from April through September, when three of the four species overlap in activity. But if you hike, hunt, or work outdoors during the cooler months, blacklegged ticks are still a concern.
Diseases Ticks Carry in Kansas
Several bacterial diseases circulate through Kansas ticks. The most commonly reported are ehrlichiosis, Rocky Mountain spotted fever and related spotted fever infections, and tularemia. All of these are transmitted by the lone star tick.
Rocky Mountain spotted fever can become serious quickly, causing high fever, severe headache, and a characteristic rash that often starts on the wrists and ankles. Tularemia, sometimes called “rabbit fever,” can cause skin ulcers at the bite site along with swollen lymph nodes and fever. Both have led to hospitalizations in Kansas in recent years.
Two rare but dangerous viruses also exist here. Bourbon virus was first identified in 2014 in a patient from Bourbon County, Kansas, and has caused fatal infections. Only five human cases have been confirmed in the U.S., all in Kansas, Oklahoma, and Missouri. Heartland virus, also carried by lone star ticks, has been found in both humans and ticks in the state. No vaccines or specific treatments exist for either virus, which makes prevention especially important.
Alpha-Gal Syndrome: The Red Meat Allergy
Lone star tick bites can trigger alpha-gal syndrome, a condition where your immune system begins reacting to a sugar molecule found in red meat, pork, and other mammal-derived products. Reactions typically happen three to six hours after eating, which makes it hard to connect to the meal. Symptoms range from hives and stomach pain to severe allergic reactions.
Alpha-gal syndrome is most common where lone star ticks live, which covers most of Kansas, particularly the eastern half. Nationally, over 110,000 suspected cases were identified between 2010 and 2022, and experts estimate the actual number could be as high as 450,000 since the condition isn’t formally tracked. If you develop unexplained allergic reactions to red meat after spending time outdoors in Kansas, a blood test can confirm the diagnosis.
How to Prevent Tick Bites
Repellents are your first line of defense. DEET in concentrations of 20% to 35% works well for most outdoor activities. Concentrations above 30% aren’t more effective, they just last longer. For children over two months old, 10% to 30% DEET is safe. Picaridin at 20% provides eight to 14 hours of protection, and products containing IR3535 offer nine to 11 hours depending on whether you use a lotion or spray.
Treating your clothing with permethrin adds a second layer of protection. You can buy 0.5% permethrin spray at most pharmacies or outdoor retailers and apply it yourself outdoors, spraying each side of the fabric for 30 to 45 seconds. Let everything dry completely before wearing it or bringing it inside. A DIY treatment lasts about six weeks or six washes. Professionally treated clothing holds up for roughly twice as long, and pre-treated clothing from outdoor retailers may last 15 washes despite manufacturer claims of 70. Permethrin is safe for people, including children and pregnant women, but it is toxic to cats.
A few habitat-awareness habits help too. Stay out of leaf litter and keep children and pets away from leaf piles. When you come home, remove your shoes outside the front door so you don’t carry ticks into the house where they can bite you, your family, or your pets later.
How to Remove a Tick Safely
Use fine-pointed tweezers and grasp the tick as close to your skin as possible, right at the mouthparts. Pull steadily upward without twisting until the tick releases. Don’t yank sharply, which can tear the mouthparts off and leave them embedded. Don’t squeeze the tick’s body, since that can push infected fluids into the bite. And skip the home remedies: petroleum jelly, nail polish, and matches don’t work and give the tick more time to transmit pathogens.
After removal, wash the bite site and your hands with soap and water, then apply rubbing alcohol or antiseptic.
Symptoms to Watch For After a Bite
In the one to four weeks following a tick bite, watch for an expanding red rash at the bite site or any combination of fever, fatigue, headache, muscle pain, and joint swelling. These symptoms can signal ehrlichiosis, spotted fever, tularemia, or other tick-borne infections. The rash doesn’t always appear, so an unexplained flu-like illness after a tick bite is reason enough to contact your healthcare provider. Early treatment with antibiotics is effective for the bacterial infections common in Kansas, but delays can lead to more serious complications.
