Utah Tick Season: When It Peaks, Which Ticks to Watch For, and How to Stay Safe
March 30, 2026
Utah’s mountains, canyons, and sagebrush flats draw millions of hikers, campers, and trail runners every year — but they’re also home to ticks that become active the moment snowmelt arrives. Most people don’t think twice about ticks until one shows up on their skin, and by then, prevention has already passed.
Understanding tick season in Utah — when it starts, where ticks hide, and what to do if you’re bitten — gives you a real advantage when spending time outdoors. Whether you’re planning a fishing trip into Utah’s backcountry or walking the dog through a brushy neighborhood trail, this guide covers everything you need to keep your family protected from spring through fall.
Key Insight: Tick-borne disease transmission in Utah is relatively low compared to the eastern U.S., but that doesn’t mean the risk is zero. Knowing the species, the season, and the signs of illness keeps you ahead of any problem.
When Is Tick Season in Utah
In Utah, the most likely time to encounter ticks is from snowmelt through mid-July, but it can vary by year, elevation, geographic location, and climatic conditions. That means your window of highest risk typically opens somewhere between late March and early May depending on where you are in the state.
The moist spring season promotes tick activity, while hot temperatures and dry summer conditions inhibit it — though ticks can also become active again in the fall. In Utah, tick season usually begins in May and lasts through the summer or early fall, with most tick bites occurring in May and June.
Spring in Utah brings rain to the mountain ranges, and moisture from spring rains and snowmelt creates perfect living conditions for ticks. For outdoor enthusiasts, traveling in the canyons this time of year could result in an unpleasant encounter with these hungry hitchhikers.
Important Note: Tick season timing shifts with elevation. Higher-elevation areas like the Wasatch Back may see later activity than lower valleys. Always check conditions for the specific area you’re visiting.
Climate also plays a role in year-to-year variation. Utah’s milder, drier conditions over the winter and into the spring can be beneficial to ticks. As one Utah State University biology professor explained, “If you have milder winters, you have the ability for those insects, those arthropods, to survive better and therefore we’ll be able to see higher numbers.”
Types of Ticks Found in Utah
Both hard ticks (Ixodidae) and soft ticks (Argasidae) may be encountered in Utah. Most of what you’ll encounter outdoors, however, falls into a small group of hard tick species that are known to attach to humans and pets.
Rocky Mountain Wood Tick
The Rocky Mountain wood tick (Dermacentor andersoni) is the most commonly encountered tick for humans and pets. Rocky Mountain wood ticks are characterized by their reddish-brown color, diffuse white pigment pattern on the scutum, and distinctive large size. This is the tick you’re most likely to pull off after a spring hike through Utah’s brushy foothills.
Western Blacklegged Tick
Western blacklegged ticks are smaller compared to other tick species, with a dark reddish-brown and black coloration. The western blacklegged tick is the only human-attaching tick capable of transmitting Lyme disease in Utah, but the likelihood of encountering this tick and contracting Lyme disease in Utah is very low. These ticks are less commonly encountered but still present in Utah, especially the southeastern corner and around Salt Lake City.
Brown Dog Tick
Brown dog ticks are reddish-brown in color and have a flattened body when unfed, which becomes engorged and elongated after feeding. They are primarily associated with dogs and are often found in kennels, homes, and other indoor environments. The brown dog tick may occasionally be brought into homes on infested dogs or animals. If your dog spends time outdoors, checking them regularly is important — not just for their health, but for yours.
Winter Tick (Moose Tick)
Winter ticks, also known as moose ticks, have a unique life cycle that involves a single blood meal during their long winter feeding period. They are small, reddish-brown ticks that primarily infest moose, elk, and other large mammals. Unlike many other tick species, winter ticks are adapted to endure cold temperatures. While they do not commonly transmit diseases to humans, heavy infestations on large mammals can lead to significant health issues.
Soft Ticks
In Utah, two soft tick species may transmit diseases. Ornithodoros parkeri may transmit tick-borne relapsing fever to humans, though encountering this tick would be a rare event. Its habitat includes burrows of prairie dogs, ground squirrels, and burrowing owls in basins and valleys. The other soft tick species, O. hermsi, may transmit Borrelia hermsii and prefers coniferous forests in mountainous regions at higher elevations.
To learn more about how ticks reproduce and complete their life cycle, understanding their biology can help you anticipate when and where they’re most active.
Tick-Borne Diseases in Utah
Tick-borne disease incidence in Utah is low. The most common disease carried by ticks in Utah is Colorado tick fever (CTF), followed by Rocky Mountain spotted fever (RMSF). On average, 1–2 CTF cases are reported annually and an average of 1 RMSF case is reported every 5 years in the state.
| Disease | Tick Vector in Utah | Key Symptoms | Relative Risk |
|---|---|---|---|
| Colorado Tick Fever | Rocky Mountain Wood Tick | Fever, chills, fatigue, muscle aches | Most common in Utah |
| Rocky Mountain Spotted Fever | Rocky Mountain Wood Tick | Fever, rash, headache | Low (approx. 1 case/5 years) |
| Lyme Disease | Western Blacklegged Tick | Bull’s-eye rash, joint pain, fatigue | Very low in Utah |
| Tick-Borne Relapsing Fever | Soft ticks (Ornithodoros spp.) | Recurring fever episodes | Rare |
The most common tick-transmitted disease in Utah is Colorado Tick Fever, a virus. Transmission of disease usually occurs 12–24 hours after feeding has begun. If you are bitten by a disease-carrying tick, expect to experience symptoms in about seven days. If a tick has fed on you, it is best to consult a doctor for treatment. Some diseases are bacterial and treatable, while some are non-treatable viruses.
Transmission of most tick-borne illnesses, including Lyme disease, requires at least 24 hours of tick attachment. Prompt removal of ticks reduces the risk of infection. This is why daily tick checks after outdoor activities are so effective — catching a tick before it has fully attached dramatically lowers your risk.
Common Mistake: Many people assume Lyme disease is a major concern in Utah. While the western blacklegged tick — the only vector for Lyme in the state — is present, the most common cause of tick-borne illness in Utah residents is Lyme disease; however, most human cases reported in Utah involve travel to Lyme-endemic areas in the Midwest.
Diagnosing tick-borne illnesses can be challenging because symptoms may not appear until weeks after exposure, and some people may not recall a tick bite. If you’ve been outdoors during tick season and develop fever, headache, muscle aches, or a rash, let your doctor know about your recent outdoor activities.

High-Risk Areas and Habitats in Utah
Utah’s diverse landscapes, from high mountain forests to arid deserts, are not just a haven for outdoor enthusiasts but also a habitat for various tick species. Knowing where ticks concentrate helps you take targeted precautions rather than worrying everywhere you go.
Ticks typically concentrate on areas where their animal hosts commonly travel. They are usually found from ground level to 3 feet above the ground in grass, low plants, and brush along the edges of fields and woodlands. In Utah, ticks tend to live in brush-filled meadows where they can easily hide and wait for a host to pass, then latch on to feed.
Typical High-Risk Habitats
- Sagebrush flats and scrublands — A defining feature of Utah’s landscape and one of the most common places to pick up a Rocky Mountain wood tick
- Canyon trails and riparian zones — Moist, brushy vegetation along creeks and rivers creates ideal tick habitat, especially in spring
- Forest edges and meadow margins — The transition zone between open fields and wooded areas is where ticks quest most actively
- Prairie dog and rodent burrow areas — Soft ticks associated with rodent burrows can be found in valleys and desert basins
- Higher-elevation conifer forests — Western blacklegged ticks favor these cooler, shadier environments
- Backyards and neighborhood trails — Ticks live in grassy, brushy, and wooded areas, or even on animals. Many people get ticks in their own yard or neighborhood.
Avoid grassy, bushy, and sagebrush areas along edges of woodlands and fields, especially from March to mid-July. The western blacklegged tick has been documented in Tooele, Millard, and Washington counties in particular, so extra vigilance is worthwhile in those areas. If you spend time in Utah’s wild spaces during Utah’s dove hunting season or other outdoor pursuits in late summer and fall, remember that ticks can still be active during warmer autumn days.
Pro Tip: Ticks don’t jump or fly to reach you. Utah’s commonly encountered ticks find hosts by “questing” — climbing vegetation and waiting for a host. The tick senses a passing host, extends its legs, and grabs on as the host brushes against the vegetation. Staying on the center of trails and avoiding brushing against vegetation are simple, effective habits.
How to Protect Yourself, Children and Pets During Tick Season in Utah
With the right precautions, tick bites are largely preventable. Whether hiking, walking the dog, or camping with your family, staying tick-aware is a simple way to protect your health all season long.
Clothing and Physical Barriers
- Wear long sleeves and pants. Light-colored clothing makes it easier to spot ticks. Tuck pants into socks or boots to prevent ticks from crawling up your legs. Wear a hat and keep long hair tied back.
- Choose light-colored fabrics so any ticks that latch on to clothing are immediately visible before they reach skin
Repellents
- Apply DEET (20–30%) on exposed skin. Treat clothing and gear with permethrin (follow product instructions carefully). Natural options include oil of lemon eucalyptus or IR3535, which are less effective but preferable to some.
- For children, use EPA-registered repellents appropriate for their age — always follow label instructions carefully
Tick Checks
Ticks may take 2 hours or longer to find a suitable feeding site and even longer to fully attach. This gives you time to find and remove them from yourself, your children, and your pets. Removing ticks before they feed is ideal for avoiding tick-vectored diseases.
According to wilderness medicine experts at University of Utah Health, the most important thing is to look over your body after you’ve been outdoors. This includes feeling through your hair and looking over your skin. Ticks are small and often cause little to no irritation at the site of attachment. They tend to attach by skin creases near joints and where clothing is tight around the body — like at your waistband.
Pay special attention to these areas during your tick check: behind the knees, groin area, belly button, armpits, behind the ears, and the scalp — especially for children with thick hair.
After Being Outdoors
- Showering within two hours helps wash away ticks and makes it easier to find them.
- Put clothes in a dryer on high heat for 10–15 minutes to kill any ticks. Wash clothes in hot water if they’re dirty.
- Check all gear, backpacks, and outdoor equipment before bringing them inside
Protecting Pets
Household pets that spend time outside, particularly dogs, can unknowingly bring ticks indoors. Even if a pet is treated with a tick preventive, it may still carry ticks on its fur, creating a potential exposure risk for everyone in the home.
Protect your pets from ticks with preventative medications, and consider treating outdoor dog gear and dog bedding with permethrin. You can also purchase pre-treated pet clothing with built-in permethrin tick repellent. For more guidance on keeping your dog safe, see these tips for preventing tick-borne diseases in dogs. You can also explore animals that naturally eat ticks as part of a broader understanding of tick control in your environment.
What to Do If You Find a Tick in Utah
Finding a tick on your skin is unsettling, but the situation is manageable if you act calmly and correctly. There is no need to rush to urgent care — ticks can be removed at home.
Step-by-Step Tick Removal
- Gather your tools. A plain set of fine-tipped tweezers works very well for tick removal. You don’t need special devices.
- Grasp the tick correctly. Use clean, fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
- Pull steadily upward. Pull upward with steady, even pressure. Don’t twist or jerk the tick, as this can cause the mouth parts to break off and remain in the skin.
- Remove it in one piece. Remove the entire tick in one piece and be careful not to leave the head in your skin.
- Clean the area. After removing the tick, thoroughly clean the bite area and your hands with rubbing alcohol or soap and water.
- Save the tick. After removal, save the tick in rubbing alcohol for identification in case symptoms develop.
Important Note: Do not burn the tick or cover it in petroleum jelly. These methods can be dangerous. Stick to the tweezers method for safe, reliable removal.
What to Watch For After a Bite
Seek medical attention if you develop any tick-borne disease symptoms, including fever, chills, headache, fatigue, muscle and joint aches, swollen lymph nodes, and a target-shaped rash at the tick site.
If you recently spent time outdoors and notice flu-like symptoms in the days following, or you came into contact with a tick and are unable to remove it completely, seek medical help right away. Nearly all associated tick diseases can be treated with antibiotics or other medications, which can clear up symptoms within a few weeks.
According to one Utah epidemiologist, “Tick-borne diseases typically will develop only if the tick has been attached to you for over 24 hours, so if you find the tick before then, you’re most likely OK.” That’s why consistent tick checks are your best line of defense.
Reporting Tick Bites and Tick-Borne Illness in Utah
Reporting your tick encounter — whether or not you become ill — contributes directly to Utah’s ability to track tick populations and disease risk across the state. The Utah Department of Health and Human Services (DHHS) conducts tick surveillance to better understand the distribution of tick species across the state, seasonal tick trends, and potential tick-borne diseases that can be acquired in Utah. All these data help identify areas of risk for certain tick-borne diseases across the state.
Where to Report and Get Help in Utah
- Utah DHHS Epidemiology Program — The state’s primary resource for tick-borne disease reporting. Visit epi.utah.gov/tickborne-diseases to report a suspected tick-borne illness or find current guidance.
- Utah Plant Pest Diagnostic Lab (USU) — If you discover a tick bite, contact the Utah Plant Pest Diagnostic Lab at Utah State University. The lab can provide identification through photos submitted via email or phone. Physical samples of ticks cannot be accepted due to safety protocols.
- Summit County Health Department — Summit County Health offers free tick species identification. Put the tick into a plastic baggie with your contact information and bring it to any of their Health Department locations, and Environmental Health staff will identify it for you. Keep in mind that the specimen will not be tested for disease.
- Your local health department — Tick surveillance efforts have been conducted with help from local health departments throughout Utah, the Division of Wildlife Resources (DWR), and Utah residents who submit tick specimens to the Utah Public Health Lab. Contact your county health department for local guidance.
Pro Tip: Whenever possible, save the tick in a sealed container or plastic bag, noting the date and location of the bite. This can be useful if you develop symptoms later and need to identify the species involved. A smartphone photo of the tick is also helpful for remote identification.
When to See a Doctor
If you’ve recently been outdoors and are experiencing symptoms of a tick-borne illness, contact a Family Medicine or Urgent Care provider in your area. Mention your outdoor activity history, the date and location of any known tick bite, and whether you saved the tick for identification. Early treatment is highly effective for the bacterial diseases ticks carry in Utah.
Staying informed, practicing consistent tick checks, and knowing who to contact if something feels wrong are the three pillars of tick safety in Utah. Staying informed, practicing safe outdoor habits, and reporting tick encounters are powerful tools to protect not just yourself, but your broader community. Utah’s outdoors are worth every adventure — a little preparation makes sure you come home healthy every time.
