# Tick season is getting longer. So is the list of states trying to keep up. **Published:** 2026-07-16T20:41:09.000Z **Source:** [Kentucky Lantern](https://kentuckylantern.com/2026/07/16/repub/tick-season-is-getting-longer-so-is-the-list-of-states-trying-to-keep-up/) **Republished from:** [Kentucky Lantern](https://kentuckylantern.com/2026/07/16/repub/tick-season-is-getting-longer-so-is-the-list-of-states-trying-to-keep-up/) (CC BY-NC-ND 4.0) **Canonical:** https://kentuckylantern.com/2026/07/16/repub/tick-season-is-getting-longer-so-is-the-list-of-states-trying-to-keep-up/ By Amanda Watford, [Kentucky Lantern](https://kentuckylantern.com) · July 16, 2026 The tiniest menace of summer doesn’t care if you’re hiking through the woods, walking the dog or pulling weeds in your backyard. It just wants a ride and a meal. As ticks spread into new parts of the country and emergency room visits for tick bites climb higher than usual, states are scrambling to monitor where the pests are showing up, what diseases they may be carrying and how to warn residents before a bite turns into something far more serious. The federal Centers for Disease Control and Prevention [reported](https://www.cdc.gov/media/releases/2026/2026-cdc-data-show-weekly-er-visits-for-tick-bites-higher-than-usual.html) in April that emergency department visits for tick bites were higher than expected across much of the United States and at their highest levels for that point in the year since 2017. In June, there were 112 tick-related ER visits per 100,000 people, compared with 110 per 100,000 during the same period last year, according to the CDC’s online tick bite [tracker](https://www.cdc.gov/ticks/data-research/facts-stats/tick-bite-data-tracker.html). That suggests this year’s summer trend may be in line with 2025. _(function(){function e(){window.addEventListener(`message`,function(e){if(e.data[`datawrapper-height`]!==void 0){var t=document.querySelectorAll(`iframe`);for(var n in e.data[`datawrapper-height`])for(var r=0,i;i=t[r];r++)if(i.contentWindow===e.source){var a=e.data[`datawrapper-height`][n]+`px`;i.style.height=a}}})}e()})(); Nationwide, the latest available data show an estimated 65 tick bite-related emergency department visits per 100,000 people, up from 47 per 100,000 last year. This year’s current figures are preliminary and subject to change, but if they hold, this year’s rate may be the highest since 2017. Health officials say the trend reflects a combination of expanding tick populations, changing environmental conditions and increased human exposure during warmer months. The concern extends well beyond Lyme disease. The lone star tick, once found primarily in the Southeast, has steadily expanded its range and is known for its aggressive host-seeking behavior, often actively crawling toward people and animals. An adult female is distinguished by a white dot or “lone star” on her back. The species has been linked to alpha-gal syndrome, an allergy that can cause people to develop severe reactions after eating beef, pork and other mammalian products. Researchers also continue to monitor ticks that carry Rocky Mountain spotted fever, anaplasmosis and other illnesses.

Some states maintain active surveillance programs that collect and test ticks to identify where disease-carrying species are becoming established. Other states rely more heavily on human disease reports or passive tick submissions, making it harder to detect changes before infections begin to rise. Those differences can leave public health officials with an incomplete picture of how quickly tick populations are changing — and where people may face the greatest risk. Several states, including Massachusetts, Missouri and Oklahoma, have expanded surveillance efforts in recent years or launched public education campaigns as tick habitats shift. All three joined the [list](https://alphagalaction.org/state-level-initiatives/) of states that now or will soon mandate reporting of alpha-gal syndrome. Other states are studying the spread of lone star ticks and the increasing recognition of the syndrome, which experts believe remains underdiagnosed.  Some experts say warmer winters in many parts of the country have allowed ticks to remain active for longer periods each year while expanding into regions where they were once uncommon. At the same time, growing white-tailed deer populations and changing land use have created more opportunities for people and ticks to cross paths. Public health officials say the best defense remains preventing bites altogether. They recommend using insect repellents [registered](https://www.epa.gov/insect-repellents/find-repellent-right-you) by the Environmental Protection Agency, wearing permethrin-treated clothing, including long sleeves and pants in wooded or grassy areas, checking people and pets for ticks after spending time outdoors and removing attached ticks as soon as they’re found. For states, the challenge is becoming less about responding to tick season and more about adapting to a future in which, in many places, the season is lasting longer — and the tiny hitchhikers are turning up in places they never did before.
