Tick Season in Texas: Peak Months, Common Species, and Bite Prevention Strategies

Texas is one of the most tick-active states in the country, and if you spend any time outdoors — hiking, hunting, gardening, or simply letting your dog roam the backyard — ticks are a real and present concern. The state’s vast land with diverse ecosystems, from arid deserts to dense forests, makes it a suitable habitat for various tick species. What makes Texas particularly challenging is that the threat doesn’t disappear when summer ends.

Tick season in Texas is no longer just a spring and summer concern — while those warmer months still see peak activity, ticks are increasingly being spotted in winter, too. That means knowing which ticks live here, when they’re most active, and how to respond to a bite isn’t just useful information — it’s essential for anyone living in or visiting the Lone Star State.

Key Insight: Understanding tick season timing and behavior is your most effective first line of defense against tick-borne illness in Texas.

When Is Tick Season in Texas

Tick season in Texas starts in April and runs until October. However, the full picture is more nuanced than a simple calendar window. Tick season in Texas can extend throughout the year due to the state’s mild climate, but ticks are most active from spring to fall. If you’re planning outdoor activities like goose hunting in Texas or trout fishing, understanding this seasonal window is critical for your safety.

Although ticks are active year-round in Texas, there is increased activity during the warmer months when populations swell, typically peaking in the summer and then declining in the fall. Spring is generally when tick encounters begin to climb sharply, making March through May an important time to start taking precautions.

The warmer climate in the South can lead to a longer tick season, sometimes spanning from late winter (February) to late fall (November). In some areas, tick activity may persist year-round due to mild winters. South Texas, in particular, sees some of the longest periods of tick activity in the state.

Important Note: “As the winters are becoming milder due to climate change, the tick breeding season and subsequent tick population has increased,” according to an infectious disease specialist at UT Physicians. Year-round vigilance is now the recommended standard for Texas residents.

When it comes to specific species timing, Lone Star ticks are most active in late spring and throughout the summer, while the Gulf Coast species is active year-round, especially in South Texas. Knowing which tick is most likely to be active during your outdoor activities helps you tailor your protective measures accordingly.

Types of Ticks Found in Texas

There are 11 common species of ticks found in Texas. The black-legged tick, brown dog tick, Lone Star tick, Gulf Coast tick, and American dog tick are the species most likely to be encountered. Each carries its own risks, behaviors, and preferred habitats. Understanding how ticks reproduce can also help you understand why populations can surge so quickly in favorable conditions.

Lone Star Tick

The Lone Star tick has a distinct white dot or “lone star” on the female’s back that helps identify it easily. It is found throughout Texas, especially in wooded, bushy areas, and is known for transmitting diseases such as ehrlichiosis and Southern Tick-Associated Rash Illness (STARI).

The Lone Star tick poses a unique risk that can trigger a rare red meat allergy, which may cause a severe allergic reaction hours after eating meat. This condition, known as Alpha-gal Syndrome, has received increased attention in recent years and makes the Lone Star tick one of the most consequential species in Texas.

American Dog Tick

The American Dog tick prefers grassy areas with little to no tree cover. It primarily targets dogs but will bite humans and can transmit Rocky Mountain spotted fever and tularemia. While this tick prefers the scent of animals, it will bite humans, especially during the spring and summer months.

Black-Legged Tick (Deer Tick)

Also known as deer ticks, black-legged ticks are present mainly in eastern and coastal regions of Texas. While they are more common and more dangerous in the northeastern United States, black-legged ticks can still be found in Texas and may transmit Lyme disease. It’s essential to be vigilant for them when spending time in areas with tall grass and brushy or wooded vegetation.

The black-legged tick is more common in areas with a higher deer population. If you spend time in wooded areas of East Texas where deer are prevalent, this is a species to watch for closely.

Brown Dog Tick

Brown Dog ticks have a reddish-brown appearance and primarily infest domesticated dogs in Texas, often found infesting kennels and homes. While they are not commonly carriers of human diseases and don’t favor human hosts, instances of human infestations have been reported. It’s important to be vigilant in protecting pets from these ticks, as they can transmit Rocky Mountain spotted fever and other hazardous canine diseases.

Unlike most species of tick found in Texas, the brown dog tick is most likely to become a household pest because it can complete its entire life cycle indoors. This makes it a unique concern for pet owners throughout the year.

Gulf Coast Tick

According to Texas A&M AgriLife Research, the Gulf Coast tick is one of the two most common ticks in Texas. Unlike the Lone Star tick, which is most active in late spring and summer, the Gulf Coast species is active year-round, especially in South Texas. It is capable of transmitting spotted fever rickettsiosis and can cause significant irritation at the bite site.

Pro Tip: Use Texas A&M AgriLife’s Tick App for Texas and the Southern Region to help identify tick species you find on yourself, your children, or your pets.

Tick-Borne Diseases in Texas

Ticks are most active in the warmer months of spring and summer and can transmit a variety of diseases. Texas residents face several significant tick-borne illnesses, though the risk profile differs from states in the Northeast. Understanding these diseases — and their symptoms — helps you seek treatment quickly if you’re exposed. You can also learn about tick-borne encephalitis, a serious viral disease transmitted by ticks in other parts of the world.

Rocky Mountain spotted fever, one of several related diseases known as spotted fever group rickettsioses, is typically characterized by fever and a measles-like rash and can cause serious illness and even death if not treated quickly. It remains one of the most medically serious tick-borne diseases you can encounter in Texas.

Lyme disease, the most frequently diagnosed tick-borne illness in the United States, is not commonly acquired in Texas — Texas is considered a low-incidence state for Lyme disease. Texas records less than 100 cases per year. That said, it’s not zero risk, and symptoms should always be taken seriously after a tick bite.

Tick-borne relapsing fever (TBRF), which is often associated with cave exploration or sleeping in rustic cabins, can cause recurring bouts of fever, headache, muscle and joint aches, and nausea. If you enjoy outdoor adventures in Central or West Texas, be aware of this less-common but uncomfortable illness.

Important Note: Monitor your health closely after any tick bite, and talk to your healthcare provider if rash, fever, headache, muscle or joint pains, or swollen lymph nodes develop within 30 days of a tick bite. These can be signs of a number of tick-borne diseases.

High-Risk Areas and Habitats in Texas

Tick encounters are most likely to occur in wooded areas or places with tall grass. But in Texas, the sheer diversity of landscapes means ticks can show up in places you might not expect — from the piney woods of East Texas to the cedar breaks of the Hill Country. If you enjoy activities like dove hunting in Texas, you’re regularly moving through prime tick habitat.

Here are the environments where your risk is highest:

• Dense forests and wooded areas: East Texas’s Pineywoods region is home to heavy populations of black-legged ticks and Lone Star ticks.
• Tall grass and brushy fields: Ticks are prolific in Texas and like to hide in tall grasses where they wait until they can latch onto someone.
• Suburban backyards near wooded edges: Ticks thrive in shaded, moist, or overgrown areas — even in well-kept neighborhoods.
• Trail edges and hiking paths: “You’ll most often encounter ticks when you enter their natural habitats,” according to Texas A&M AgriLife Research entomologist Pete Teel.
• Caves and rustic cabins: Soft ticks associated with tick-borne relapsing fever are found in these environments, particularly in Central and West Texas.
• Areas with high deer populations: The black-legged tick is more common in areas with a higher deer population. Deer are a primary host, and their range directly maps tick distribution.

In humid regions like the Gulf Coast, recurring professional treatments may be needed more frequently due to high tick populations and fast vegetation growth. Coastal and southeastern Texas residents face an extended risk window compared to drier parts of the state. Animals that eat ticks — such as opossums and certain birds — can play a natural role in keeping local tick populations in check.

Pro Tip: When hiking or camping, stay in the middle of the trail and avoid heavy vegetation to reduce your chances of brushing against tick-laden grass or brush.

How to Protect Yourself, Children and Pets During Tick Season in Texas

Protecting your family during tick season requires a layered approach — combining clothing strategies, repellents, yard management, and thorough tick checks. Many veterinarians in Texas recommend year-round protection due to the extended tick season. The same year-round mindset applies to people, too.

Protective Clothing

The best defense against ticks is similar to mosquito protection: wear long-sleeve shirts and pants when hiking or spending time in wooded areas. Headwear and light-colored clothing that protects as much skin as possible is a good idea if you’ll be where ticks might be present. Light-colored clothing makes it easier to see the ticks that may have hitched a ride. Pants should be tucked into socks and boots to minimize the odds of an unwanted bloodsucker attaching.

Repellents

Apply DEET or permethrin to clothing to repel ticks. Use a repellent with at least 20% DEET on exposed skin and clothing. For those who prefer a natural option, products containing the oil of lemon eucalyptus can also provide protection.

Protecting Children

Parents should take extra precautions with kids who play outside. Use insect repellent, dress them in protective clothing, and do a tick check at the end of the day. Ticks can be easy to miss, especially in their poppy seed-sized nymph stage.

After outdoor play, check the areas where ticks typically latch on: head, hair, chest, armpit, groin, waist, and back of the knees. Make tick checks a routine part of bathtime for younger children.

Protecting Pets

Pets are frequent tick carriers, and an untreated pet can bring ticks directly into your home. Choose from oral medications, spot-on treatments, tick collars, or combination products that also repel fleas and mosquitoes. Talk to your vet about which product is best suited for the tick species common in your area. For more detailed guidance, explore these tips for preventing tick-borne diseases in your dog.

When checking your pets, run your fingers through their fur and watch out for little bumps that may turn out to be ticks. Check their entire body, including their neck, face, between their toes, and around their legs.

Yard Management

• Mow regularly and avoid tall vegetation around the home’s perimeter.
• Ticks love shady, moist ground — clear out brush, leaves, and clippings. Use gravel or mulch borders between wooded areas and your lawn to limit migration.
• Remove bird feeders and other food sources that attract wildlife, such as deer, that can carry ticks.
• Move picnic tables, swing sets, and outdoor lawn furniture away from trees and shrubs.

Common Mistake: Many people only check for ticks after hiking. In reality, ticks carry multiple diseases even in urban and suburban areas — you don’t need to be hiking through the woods to encounter ticks. They can be right in your backyard.

What to Do If You Find a Tick in Texas

Finding a tick on yourself, a child, or a pet can be unsettling, but staying calm and acting promptly makes a significant difference. Ticks need to feed on your skin for more than 24 hours to transmit infections such as Lyme disease, which means quick removal is one of the most effective protective actions you can take.

How to Remove a Tick Safely

1. Use the right tool: Use fine-tipped tweezers or a tick-removal tool to grasp the tick as close to the skin as possible.
2. Pull steadily: Pull straight out with steady, even pressure. Avoid twisting or jerking, which can cause mouthparts to break off and remain in the skin.
3. Clean the area: Clean the area with an alcohol swab or antiseptic after removing the whole tick.
4. Save the tick: Once the tick is removed, consider placing it in a closed bottle or bag and saving it. Ticks removed from Texas citizens can be submitted for identification and tick-borne pathogen testing free of charge to the Texas Department of State Health Services.
5. Monitor for symptoms: Watch for rash, fever, fatigue, or muscle aches in the days and weeks following the bite.

Important Note: Do not remove ticks by squeezing them, coating them with petroleum jelly, or burning them with a match. These methods can cause the tick to release more saliva into the bite, increasing the risk of disease transmission.

Tick bites can vary in appearance and often look like a mosquito bite with a dark spot in the center where the tick is still attached. Lyme disease presents as a rash that looks like a circle or bullseye. If you notice this type of rash, contact your healthcare provider promptly.

Should a rash develop within several weeks of the tick being removed, or if you have a fever, consult a physician. Early treatment of most tick-borne diseases is highly effective, so don’t delay if symptoms appear.

Reporting Tick Bites and Tick-Borne Illness in Texas

Texas has dedicated resources for tick surveillance and disease reporting, and using them benefits both your personal health and the broader community. When ticks are tracked and tested, public health officials can better understand where disease risks are highest across the state.

Submitting a Tick for Testing

The Department of State Health Services (DSHS) and the University of North Texas Health Science Center (UNTHSC) Tick-Borne Disease Research Laboratory have teamed up to test ticks for disease agents in the Borrelia, Ehrlichia, and Rickettsia genera using molecular methods. Ticks should be submitted to the DSHS Zoonosis Control office for identification, after which they will be forwarded to UNTHSC for testing. There is no charge for testing. However, this service is available only to Texas residents submitting ticks found at a location within Texas. Only ticks attached to a human should be submitted.

For free testing of ticks found in the environment or on pets, you can visit the Texas Tick Project. The program is designed for tick surveillance, not disease diagnosis. It’s a valuable resource for understanding tick activity in your local area.

Pro Tip: For information on ticks, tick attachment, and tick bites, contact your Regional Zoonosis Control office or email The.Vet@dshs.texas.gov. They can provide guidance specific to your region of Texas.

Reporting Tick-Borne Illness

Texas law requires reporting of certain tick-borne diseases within one week. There are several laws in Texas that require doctors, hospitals, schools, and labs to inform the Texas Department of State Health Services (DSHS) if they think someone has a notifiable condition. If you’ve been diagnosed with a tick-borne illness, your healthcare provider is responsible for filing this report.

As a patient, your role is to provide your doctor with as much information as possible — including the date and location of the tick bite, the type of tick if you know it, and how long it was attached. This information helps with accurate diagnosis and contributes to statewide tick-borne disease surveillance. You can also visit the Texas DSHS tick-borne diseases page for the most current information on reportable conditions and regional outbreak alerts.

Using the CDC and Texas A&M Resources

To learn more and see maps of where tick species live in Texas and across the U.S., visit the Centers for Disease Control and Prevention’s page about where ticks live. To see more Texas tick species, visit Texas A&M AgriLife’s tick app. Both tools are free and regularly updated, making them excellent resources for residents and outdoor enthusiasts throughout the state.

Staying informed, acting quickly after a bite, and reporting illness when it occurs are the most meaningful steps you can take — not just for your own health, but for the health of your community. Whether you’re spending time in the backyard or heading out for a day of fishing or dove hunting, a little preparation goes a long way during tick season in Texas.
