Tick season in Kentucky
Tick season in Kentucky runs whenever the ground is not frozen, roughly March through November, with two peaks. Nymph deer ticks, the poppy-seed-sized stage that causes most Lyme cases, peak from late May through July. Adult deer ticks make a second push in October and November, and on any winter day above about 40 F they can quest again. American dog ticks are busiest from April through July.
| Life stage | J | F | M | A | M | J | J | A | S | O | N | D |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Deer tick nymphs | ||||||||||||
| Deer tick adults | ||||||||||||
| American dog tick | ||||||||||||
| Lone star tick |
Those are averages, and any single week can run hotter or colder than the calendar suggests. The daily score on every town page folds the season, the weather, and local habitat into one number each morning, so it is the safer way to time yard work, hikes, and pet prevention.
Highest-risk towns in Kentucky (2026)

They are active whenever the ground is not frozen, and today 207 of the state's 446 towns are at moderate or high tick risk on TickZone's daily score.
- What types of ticks live in Kentucky?
