Study suggests some ticks can persist indoors for up to 3 weeks

Version 1 — Brief

An Ohio State University study found that lone star ticks and Gulf Coast ticks can survive indoors on common household flooring for far longer than many people may assume, with survival ranging from at least one week to about three weeks depending on the species and surface. The work, published online March 13, 2026, in the Journal of Vector Ecology, tested tile, vinyl, wood, and both short- and long-pile carpet. Gulf Coast ticks generally survived longer than lone star ticks, except on long-pile carpet, where lone star ticks lasted longer. The finding adds evidence that ticks carried inside on dogs, clothing, or gear may remain a bite risk in the home rather than dying quickly. (vet.osu.edu)

Why it matters: For veterinary professionals, the study sharpens the message around year-round tick prevention and home-risk counseling. Both species are relevant to animal and public health: Gulf Coast ticks are associated with Hepatozoon americanum transmission in canids, and lone star ticks are tied to several human and animal health concerns, including ehrlichiosis and alpha-gal syndrome. That means post-walk advice shouldn’t stop at “check outside” — clinics may also want to remind pet parents to inspect pets promptly after outdoor exposure, launder or heat-treat clothing, and be mindful that carpeted areas may allow some ticks to persist.

What to watch: Expect more discussion this tick season around how veterinarians translate indoor-survival data into practical prevention, cleaning, and client education protocols. (u.osu.edu)
