Ticks used to be something many hunters worried about in spring turkey season and early bow season, then mostly forgot once hard frosts hit. In large parts of the country, that pattern is fading. Milder winters, expanding deer and small-mammal populations and changing land use have combined to give ticks a longer active season and, in some places, no real break at all. Layer on the growing list of tick-borne diseases—Lyme, ehrlichiosis, anaplasmosis, Rocky Mountain spotted fever and the meat allergy linked to lone star ticks—and you have a background risk that now extends well beyond a few warm months. While ticks exist almost everywhere, hunters in certain states are reporting year-round or near year-round activity often enough to change their habits permanently.
Texas
In Texas, hunters can chase something almost every month, and ticks seem to follow suit. The state’s size and varied climate mean you might see fewer ticks in the Panhandle during a hard cold spell, but in much of the Hill Country, South Texas brush and Piney Woods, mild winters let ticks stay active on deer, hogs and small game for most of the year. Hunters running feeders, checking trail cameras or stalking pigs in January report picking ticks off pant legs and dogs even when mornings feel cool. That reality has pushed a lot of Texas hunters to treat clothing with permethrin, keep repellent in their trucks and make tick checks a normal part of cleaning up after any trip into waist-high grass or thick brush.
Florida
Florida’s long, humid warm season provides ideal conditions for ticks to stay active nearly all year. Whitetails, hogs and small mammals carry them through swamps, pine flatwoods and oak hammocks, and there is rarely a month when temperatures fall low enough for long enough to shut them down statewide. Hunters glassing hogs, running dogs or slipping along creek bottoms for deer can gather clusters of ticks on socks and boot tops in months that would count as deep winter farther north. Because many Floridians also live in close proximity to greenbelts and overgrown lots, it’s common to find ticks picked up both in the woods and in suburban backyards. For many, the only practical strategy is to assume ticks are a 12-month concern and use clothing, repellents and post-hunt showers accordingly.
Georgia
Georgia sits at the heart of the Southeast’s tick country, with a mix of hardwoods, pines, thickets and edge habitat that suits whitetails and small mammals perfectly. Winters are often mild, especially in the southern half of the state, and warm spells can kick ticks back into gear even in what used to be considered off-season months. Turkey hunters, hog hunters and deer hunters all report seeing ticks from early spring into late fall, with enough activity on warm winter days that many simply treat every woods trip the same. The variety of tick species present means Georgians also pay attention to disease risk, and state health officials regularly remind residents and hunters that long pants, treated clothing and thorough skin checks aren’t just for April—they’re smart precautions whenever you’ve been moving through brush or bedding cover.
California
California’s size and range of climates hide how much of the state offers good tick habitat. Coastal regions, oak woodlands and foothill country in particular can host heavy tick populations on deer and small mammals, and Mediterranean-style winters there are cool and wet rather than deep-frozen. Hunters chasing blacktail deer, pigs and turkeys in these areas often deal with ticks well into winter, because temperatures rarely stay below freezing long enough to cut them off. Areas with green grass and leaf litter stay hospitable to ticks even when the calendar says it should be “off season.” As a result, many California hunters who spend time in brushy foothills and coastal timber treat tick precautions as standard gear, right alongside snake gaiters and rain shells.
Arizona
Arizona doesn’t always appear in national tick conversations because much of the state is dry, but pockets of brush, riparian corridors and higher-elevation forests create more tick habitat than people expect. Coues deer, elk and other big game carry ticks at altitude, while pockets of denser vegetation in central and southern Arizona can harbor them in cooler months when people are out calling coyotes or chasing javelina. Because many hunts take place on mild winter days when temperatures are comfortable and long sleeves feel optional, it’s easy to forget that ticks can still be active in sheltered cover. Hunters who spend a lot of days in Arizona’s mixed terrain often take a conservative approach: long pants, deliberate clothing choices and a quick once-over in the shower regardless of whether they felt “like tick weather” out in the field.
Pennsylvania
Pennsylvania has become a case study in how serious tick-borne disease can get. The state consistently ranks near the top of national Lyme disease counts, and large whitetail and rodent populations give ticks plenty of hosts. Winters are not as harsh as they once were, and warm spells in late fall, midwinter and early spring often produce enough bare ground and above-freezing temperatures to wake ticks back up. Deer, small game and predator hunters who move through brushy creekbottoms, edge cover and second-growth timber routinely report finding ticks outside the traditional May–June peak. Many now treat every trip into brush with the same caution, regardless of season, and pay close attention to symptoms that could indicate early tick-borne illness after long runs of days in the woods.
New York
New York, especially its Hudson Valley, Long Island and parts of upstate, is another place where tick issues have become a year-round discussion. Dense human and deer populations overlap heavily, and there is no shortage of edge habitat where ticks can thrive. Bowhunters, small-game hunters and late-season deer hunters all share stories of plucking ticks off clothing during what used to be considered “cold months,” particularly during stretches of unseasonably warm weather. For many New York hunters, permethrin-treated clothing, tucking pants into socks or boots and drying clothes on high heat after outings have shifted from optional to normal practice. They’ve also become more aware of the wide range of diseases beyond Lyme that ticks in their state can carry, and that awareness has changed how they approach the woods all year.
New Jersey
New Jersey may be small, but it has a high concentration of people, whitetails and green spaces, which together create a near-perfect machine for sustaining tick populations. Hunters are often moving through the same patches of woods that joggers, dog walkers and kids use, and there is little seasonal relief in many areas. Warmer winters have led to a pattern where a few mild days in January or February can produce active ticks on deer trails and in leaf litter, even when most people assume the risk is gone. New Jersey hunters who’ve dealt with tick bites and Lyme diagnoses tend to be vocal about prevention, and it’s common to hear them talk about tick checks as part of unloading the truck and hanging up camo, regardless of the month printed on their tag.
Wisconsin
Wisconsin combines classic northern deer country with enough warm months and edge habitat to support robust tick numbers. Hard freezes still knock populations back more than in the Deep South, but shoulder seasons have stretched, and regular swings into warmer temperatures keep ticks active later into fall and earlier in spring. Archery, gun and late-season small-game hunters report pulling ticks during mild spells that would once have been considered safe stretches. With Lyme and other tick-borne diseases firmly established in the Upper Midwest, many Wisconsin hunters now assume that any day in brush, CRP or timber when the snow isn’t deep can be a tick day, and they dress and plan accordingly.
Minnesota
Minnesota’s mix of forests, wetlands and farmland has made it another Upper Midwest state where ticks and tick-borne disease have become part of normal hunting conversations. Long-standing deer traditions keep people in the woods from early bow season through late firearms and muzzleloader seasons, and relatively mild periods within the broader winter can give ticks windows to stay active on deer trails and under leaf litter. Hunters who grew up assuming that “frost kills ticks” have seen enough counterexamples now that many no longer rely on that belief. Instead, they use repellents, treat clothing, inspect dogs carefully and treat every bare-ground outing from spring through late fall as an exposure opportunity. The need for that mindset is one of the clearest signs that tick issues have shifted from seasonal to nearly year-round in many parts of the country.
