Deer ticks, Lyme disease carriers, found in Montana

Laura Lundquist

(Missoula Current) Montana appears to have a new invasive species, and this one could come with a few nasty parasites.

The Montana Department of Public Health and Human Services announced last week that three blacklegged ticks, also called deer ticks, have been found in eastern Montana over the past year. While the ticks aren’t necessarily pleasant, the real problem is that they’re known to carry Lyme disease, in addition to several other parasites that can infect people and animals.

The first blacklegged tick was found in Dawson County around Glendive earlier in 2024. A man found the tick on his hunting dog and sent it to the Montana State University Extension’s Schutter Diagnostic Lab, where diagnostician Marni Rolston identified it. Rolston collaborated with scientists at the National Institutes of Health’s Rocky Mountain Laboratory in Hamilton to confirm the identification.

“This discovery is incredibly important because it greatly expands the geographic range of the blacklegged tick, a carrier of the pathogen that causes Lyme Disease,” said Bob Peterson, an MSU entomologist in a release. “The implications of finding this tick in Montana cannot be overstated.”

In the fall of 2024, two more ticks were found in Sheridan County in far northeast Montana, an area popular for bird hunting, and DPHHS, along with the Centers for Disease Control and Prevention, confirmed they were blacklegged ticks.

The percentage of blacklegged ticks that are infected with Lyme disease ranges from none to more than 50% of a population, depending on the area and life stage. Lyme disease infection occurs mostly in the northeastern, mid-Atlantic, and north-central United States, according to the CDC. Blacklegged ticks found in most areas of the southeastern United States are almost never infected.

Lyme disease can produce a wide range of symptoms, depending on the stage of infection. These include fever, rash, facial paralysis, an irregular heartbeat and arthritis.

No pathogens were found on the ticks in Montana, according to the DPHHS. But their presence means Montanans should be alert, particularly in Dawson and Sheridan counties, said Devon Cozart, DPHHS vector-borne disease epidemiologist.

“The presence of this new type of tick in the state could mean that Montanans have an increased risk of exposure to diseases that weren’t previously a threat in Montana,” Cozart said in a release. “These ticks could have been carried into the state by a host animal, or they could be active and reproducing here – we just don’t know yet. We will be conducting further investigations this spring.”

Blacklegged ticks are not native to Montana. Research indicates they survived the Ice Age in the southeastern U.S. and then steadily expanded northward during the 20th century, spurred by reforestation, a warming climate and animal hosts moving north. In addition, blacklegged ticks have subsequently been spreading west, followed by the lone star tick.

Research has shown that several species can serve as migration vectors for ticks, including deer and migratory birds. People can also factor in, because they move animals around, including horses and dogs. In recent years, the number of nonresidents using eastern Montana to train their dogs in the winter and hunt in the fall has surged. Just like ticks can be carried into your house, one or two ticks could hitch rides to Montana on nonresident dogs from the hotbeds of Minnesota, Iowa and Wisconsin.

If anything, dog owners should be concerned because pets can get Lyme disease too. In most cases, a tick must be attached for more than 24 hours before the Lyme disease bacterium can be transmitted, according to the CDC. If you remove a tick within 24 hours, you can greatly reduce the chances of you or your pets getting Lyme disease.

According to the CDC, the established populations currently closest to Montana are in the eastern portions of the Dakotas and throughout Minnesota. A November 2023 CDC scientific review concluded that, because black-legged ticks have established in counties in the far eastern parts of Nebraska and the Dakotas, “it is reasonable to assume that (blacklegged ticks) invaded in recent decades from the eastern neighboring states of Minnesota and Iowa.”

The map showing tick presence could change to include Montana if researchers find more ticks. To that end, DPHHS is launching a citizen-scientist program and is requesting the public’s help in tick surveillance, especially in Dawson and Sheridan counties. Anyone who thinks they have found a blacklegged tick is encouraged to fill out this online form.

Montana is home to the Rocky Mountain wood tick and the American dog tick, which can also spread diseases such as Rocky Mountain spotted fever and Colorado tick fever. These ticks tend to be brown and are much larger than the dark-red deer tick.

Montana smokejumper Sam Forstag aims to flip House seat blue

Montana hasn’t elected a Democrat to the House since the late 1990s. Smokejumper Sam Forstag, who jumps out of planes into the remote wilderness to put out wildfires, is trying to change that. Forstag joins “The Takeout” to lay out his progressive campaign in the deep-red state.

Amazing America: Smokejumpers share how job evolved through the years

MISSOULA, Mont. — In this week’s Amazing America, NBC Montana is highlighting smokejumpers and their efforts to keep our communities safe during wildfire season.

NBC Montana caught up with a current and a former smokejumper to learn more about the work they do and how the job has changed throughout the years.

Jim Kitchen was a smokejumper for 20 seasons, fought over 100 fires and raised his three daughters on a smokejumper base, where he served as base commander.

Kitchen says he’ll never forget his first jump, when he started training in Fairbanks, Alaska, in 1987.

“I went, ‘That was amazing,’ and he goes, ‘Yeah,’ and I go, ‘Have you ever done anything as amazing in your life? I mean, we just made our first jump,” said Kitchen.

Kitchen told NBC Montana when he laughed his crew had to do 50 pushups.

Kitchen saw several changes during his career, including women entering a historically male-dominated field. He told NBC Montana Deanne Shulman, the first woman smokejumper, paved the way for the industry.

He recalled a time when he was on a trip to Washington, D.C. , in the early ’90s to coordinate emergency response, when a U.S. Department of State official asked him a question.

“He goes, ‘I didn’t realize men were smokejumpers.’ And I had to go, ‘Peter, I’ll have you know, there’s quite a few of us, and actually, it’s the women that are rare,’” said Kitchen “The early ladies in smokejumping, they always met and exceeded the bar, and they were instrumental in doing these winter details.”

Another change he oversaw as base commander, was moving from round parachutes used in World War II, to the ones used today.

“Ram-Air parachutes that inflate make the shape of the wing and they actually have about a 20 mph forward speed. And so you can you can fly those in much windier conditions, higher elevations,” said Kitchen.

Kitchen says the job requires you to roll with the punches and make quick decisions on the fly.

He said while training new jumpers, he taught them early to prepare and never hesitate.

“The only thing that we ask of you is that you take all the information that you can and then make a decision,” said Kitchen.

Nick Holloway, a current Missoula smokejumper, who’s been working for 14 seasons, says it’s important to rely on your training, stay positive and persevere.

“Having done this for a few years, it’s just trying to know that essentially every season is a marathon, it’s not a sprint. Just stay healthy, stay focused and keep having a good time,” said Holloway.

NBC Montana asked both men what they were most proud of during their time jumping.

Kitchen recalled fighting a fire near the Grand Canyon, when he and his crew decided to manage a fire instead of suppressing it when they ponderosa pine trees.

The crew let the fire burn to a plateau, “The Ponderosa pine has about a 20 to 30-year fire return interval in that area,” said Kitchen. “That’s one of the high points as far as land stewardship of my career is seeing fire on a landscape escape and not necessarily suppressing it but allowing it to burn, because then you’re saying it’s good for decades after that.”

Holloway told NBC Montana, while he has “too many to count,” he’s most proud that recently he jumped a 3- to 5-acre fire at Yellowstone National Park.

The fire grew to 8 acres, “So seven days later we got around everything, put it all out and essentially with a good product upon departure. So it’s just a classic example of a smokejumper fire.”

Holloway says staying fit for annual trainings, regardless of experience, is critical to staying fire-ready.

“Pushups, pullups, sit-ups, a certain amount and then a mile and a half in a certain time as well,” said Holloway.

Kitchen told NBC Montana he still does his pullups, pushups and sit-ups.

“Many of my colleagues are still in really fit shape even in their 60s, 70s and 80s,” he said.
