More ticks means more chances for someone to get bitten
When winter loosens its grip too gently, the natural world takes notice in ways that ripple outward into human life. Across Colorado this season, a mild winter has allowed tick populations to swell beyond typical numbers, prompting public health officials to issue warnings about elevated risks of Lyme disease and Rocky Mountain spotted fever. The concern reflects something larger than a single season's weather — it speaks to a gradual shift in climate patterns that is quietly redrawing the boundaries of when and where certain dangers exist. As residents prepare to spend more time outdoors, the invitation to enjoy the landscape now carries a small but serious obligation to pay attention.
- A winter too warm to cull tick populations has set the stage for an unusually dense tick season across Colorado, catching many residents off guard.
- Public health officials are racing to close a persistent awareness gap — many people still don't know how to safely remove a tick or where to check their bodies after time outdoors.
- The diseases ticks carry, including Lyme disease and Rocky Mountain spotted fever, are not minor inconveniences; a surge in tick numbers means a direct surge in potential human illness.
- Climate patterns are extending the active tick season well beyond its traditional window, turning what was once a late-spring concern into a near year-round consideration.
- Health agencies are urging Coloradans to treat tick prevention with the same seriousness as any other health precaution — proper clothing, repellents, and thorough body checks after every outdoor excursion.
The winter just passed felt almost forgiving — mild enough that few paused to consider its consequences. But Colorado's public health officials are bracing for one of them: tick populations across the state are expected to be significantly higher than usual this year.
Mild winters are ideal for ticks. More survived the cold months, more had time to feed and reproduce, and now, as people move outdoors with the season, health agencies are warning that elevated tick numbers mean elevated risk. The diseases these insects carry — Lyme disease, Rocky Mountain spotted fever, among others — are serious, and more ticks in the landscape means more opportunities for transmission.
Public health agencies are already tracking populations and pushing education campaigns, because despite years of awareness efforts, many residents still don't know how to protect themselves. Common mistakes persist: improper tick removal, incomplete body checks after hikes, and underestimating where ticks wait — in tall grass, brush, and the edges where wild and suburban spaces meet.
This year's surge isn't an isolated event. Warming trends have been gradually extending the tick season, stretching what was once a late-spring concern into fall and sometimes beyond. Colorado's varied geography — forests, grasslands, and wildlife corridors threading through populated areas — makes it particularly hospitable terrain.
The guidance from officials is practical and urgent: wear light-colored clothing, tuck pants into socks, use DEET or permethrin repellent, and check your entire body carefully after time outdoors. If a tick is found, remove it with tweezers, pulling straight out without twisting or squeezing. The tick season is arriving with unusual force this year. Whether residents meet it with equal preparation remains the open question.
The winter that just passed was mild enough to feel almost pleasant—the kind of season that makes you forget to dread the cold. But Colorado's public health officials are already bracing for a consequence most people would rather not think about: ticks are coming, and there will be a lot of them.
Mild winters are a tick's dream. The insects that survived the cold months did so in larger numbers than usual, and the warmer temperatures meant they had more time to feed, reproduce, and prepare for spring. Now, as the season shifts and people begin spending more time outdoors, health officials are warning residents to expect elevated tick populations across the state. The concern isn't merely about the nuisance of finding a tick on your skin—it's about the diseases these creatures carry. Lyme disease, Rocky Mountain spotted fever, and other tick-borne illnesses pose real health risks, and a surge in tick numbers means a surge in potential exposures.
Public health agencies across Colorado are already in motion, tracking tick populations and trying to educate residents about prevention. The work is necessary because, despite decades of awareness campaigns, many people still don't know how to protect themselves or what to do if they find a tick. Some remove ticks incorrectly, which can increase the risk of disease transmission. Others don't check themselves thoroughly after hiking or spending time in tall grass and brush—the places where ticks wait for a host to brush past.
The mild winter is just one piece of the puzzle. Climate patterns have been shifting for years, and warmer seasons overall have been extending the window during which ticks are active. What was once a concern limited to late spring and summer now stretches into fall and sometimes even early winter. Colorado's geography—with its mix of forests, grasslands, and suburban areas where wildlife and human spaces overlap—creates ideal habitat for ticks to thrive.
For residents, the message from health officials is straightforward but requires vigilance. Wear light-colored clothing when hiking or working outdoors, tuck pants into socks, and use insect repellent containing DEET or permethrin. After coming inside, check your entire body for ticks, paying special attention to warm, moist areas like the groin, armpits, and behind the ears. If you find a tick, remove it promptly with tweezers, grasping it as close to the skin as possible and pulling straight out—not twisting, not squeezing, not applying heat or petroleum jelly, all of which are common mistakes.
What makes this year different from previous tick seasons is the sheer numbers health officials expect to encounter. The mild winter wasn't an anomaly; it's part of a broader warming trend. As Colorado heads into summer, outdoor enthusiasts should assume ticks are present in any brushy or wooded area. Hikers, campers, and even people working in their yards need to treat tick prevention as seriously as they would any other health precaution. The tick population surge is coming. The question now is whether residents will be ready.

The Hearth Conversation Another angle on the story
Why does a mild winter specifically create more ticks? Don't they just survive in cold anyway?
Ticks don't really survive harsh winters well. Many die in extreme cold. A mild winter means more of them make it through, and they have more time to feed and reproduce before spring arrives. It's a numbers game—more survivors means exponentially more ticks by the time warm weather hits.
So this is just about quantity, not about the ticks themselves being more dangerous?
The ticks themselves aren't more dangerous, but there are more of them hunting. More ticks means more chances for someone to get bitten, and more chances for disease transmission. If you encounter one tick on a hike, that's manageable. If you encounter five, the odds shift.
What's the most common mistake people make when they find a tick?
They panic and grab it wrong. Twisting it, squeezing it, applying heat—all of that can cause the tick to regurgitate its stomach contents into your skin, which actually increases disease transmission risk. People think they're being thorough when they're actually making things worse.
Is this something that will get worse year after year?
That's the real concern. This isn't a one-year spike. The warming trend is ongoing. We're seeing tick seasons start earlier and last longer. Colorado's geography—forests, grasslands, suburbs all mixed together—is perfect habitat. This could become the new normal.
What should someone actually do if they're planning to hike this summer?
Treat it like any other health precaution. Light clothes, tuck your pants in, use repellent. Check yourself thoroughly when you come home. Know how to remove a tick correctly. It's not complicated, but it requires attention. Most people don't do it, and that's where the risk lives.
