Ticks in Oklahoma

Ticks are active in Oklahoma nearly year-round, led by the lone star tick. TickZone scores all 609 Oklahoma towns every morning, so risk stays local: pick your town for today's number, a 7-day outlook, and what's driving it.

Tick season in Oklahoma

Tick season in Oklahoma effectively runs year-round: winters rarely stay cold long enough to fully shut ticks down. Lone star ticks ramp up first in early spring, peak from April through July, and their larval "seed tick" swarms hit hardest in late summer. American dog ticks are busiest from spring through midsummer, and adult ticks of every species can still quest on mild winter days.

That means prevention never fully comes off in Oklahoma: the safer way to time it is by the day, not the month. The daily score on every town page folds the season, the weather, and local habitat into one number each morning.

Oklahoma tick questions

Are there ticks in Oklahoma?
Yes. Oklahoma has ticks in every county, led by the lone star tick, with the American dog tick, Gulf Coast tick, brown dog tick, and deer tick also present. Ticks here stay active nearly year-round, and today 0 of the state's 609 towns are at moderate or high tick risk on TickZone's daily score.
What types of ticks live in Oklahoma?
Oklahoma has five human-biting ticks: the lone star tick (established statewide, the state's most common human-biting tick and the main cause of alpha-gal syndrome), the Gulf Coast tick (not established), the American dog tick, the brown dog tick, and the deer tick (blacklegged tick), which carries Lyme disease but bites people far less often this far south. See the Oklahoma tick identification chart for photos and how to tell them apart.
When does tick season start and end in Oklahoma?
In Oklahoma, ticks are active nearly year-round: the region rarely gets a hard freeze long enough to fully shut them down. The lone star tick ramps up earliest in spring, peaks in midsummer, and its larval "seed tick" swarms hit hardest in late summer. Adult ticks can still quest on mild winter days.
When is flea and tick season?
Flea and tick season generally runs from early spring through late fall, peaking in the warm summer months. In Oklahoma, start prevention for pets and people in March and keep it up through November, since ticks can bite on any mild day.
Which tick carries Lyme disease in Oklahoma?
The deer tick, also called the blacklegged tick, is the tick that spreads Lyme disease, but it is a minor factor in Oklahoma. The lone star tick does not carry Lyme, but its bite causes alpha-gal syndrome, and it bites people far more often here than the deer tick does.
Does Oklahoma have lone star ticks that cause alpha-gal syndrome?
Yes. The lone star tick is established across Oklahoma and is the tick most responsible for human bites in the state. Its bite can trigger alpha-gal syndrome, a delayed allergy to red meat and other mammal products, along with ehrlichiosis and STARI.
