North DFW — including communities such as Frisco, Plano, McKinney, Allen, Prosper, Little Elm, and surrounding areas, sits within a rapidly growing suburban landscape bordered by greenbelts, creek systems, parks, and undeveloped land. Combined with warm temperatures, seasonal rainfall, and generally mild winters, these conditions support tick activity from early spring through late fall, with some species remaining active during warmer winter periods.
Ticks in North DFW are commonly encountered by residents, outdoor enthusiasts, and pets, particularly in grassy, wooded, or brush-heavy environments.
The most common and aggressive tick species across North Texas.
Key traits:
Easily recognized by the white “lone star” marking on adult females.
Actively seeks hosts rather than waiting passively.
Common in wooded areas, brush, tall grass, and shaded yards.
Known to transmit ehrlichiosis.
Associated with alpha-gal syndrome, a red meat sensitivity linked to tick bites.
Widespread throughout Collin, Denton, and Dallas counties.
Key traits:
Most active from late spring through summer.
Common in open grassy fields, trails, parks, and roadside vegetation.
Primary vector for Rocky Mountain spotted fever in Texas.

Key traits:

Encounters often occur near creek corridors and forest edges.
Early Spring: Lone star and deer ticks become active as temperatures rise above 50°F.
Late Spring–Summer: American dog ticks peak in grassy and open environments.
Fall: Lone star and deer ticks remain active during warm spells.
