Study finds some ticks can survive weeks on home flooring: full analysis

A new Ohio State University study is giving veterinary professionals firmer evidence for something many already suspected: ticks brought into the home don’t necessarily die off quickly. In work published in the Journal of Vector Ecology, researchers found that adult Gulf Coast ticks and lone star ticks could survive at least a week, and in some cases about three weeks, on common household flooring. Ohio State said the findings offer the first scientific evidence for how long these species can persist on indoor floor surfaces. (bpb-us-w2.wpmucdn.com)

The study arrives as tick exposure remains a growing concern for both animal and human health. CDC says lone star ticks are now widely distributed across the Northeast, South, and Midwest, with established populations tracked through 2024. More broadly, Ohio State noted that reported U.S. tick-borne disease cases increased 40% from 2019 to 2022, underscoring why indoor carry-in risk matters beyond the bite that happens outdoors.

In the experiment, investigators placed 180 unfed adult ticks, 90 Gulf Coast and 90 lone star, individually on five flooring types: tile, wood, vinyl, short-pile carpet, and long-pile carpet. Under ambient lab conditions of about 23°C and 42% relative humidity, Gulf Coast ticks survived significantly longer than lone star ticks on vinyl, wood, tile, and short-pile carpet. Reported median survival was 22.5 days for Gulf Coast ticks on vinyl versus 11.5 days for lone star ticks, 21.0 versus 6.5 days on tile, 18.5 versus 11.0 days on wood, and 20.0 versus 10.5 days on short-pile carpet. Long-pile carpet was the exception: lone star ticks lived longer overall there, with mean survival of 14.9 days versus 10.4 days for Gulf Coast ticks. (bpb-us-w2.wpmucdn.com)

Ohio State researchers framed the findings as a practical message for households and clinics rather than a signal of indoor infestation in the traditional sense. First author Afsoon Sabet said ticks can pose a risk “even in the places you least expect,” while co-senior author Risa Pesapane said the public health goal is to reinforce that ticks brought into the home on pets or people could still be a risk and that the data should encourage tick checks. Those comments align with the paper’s conclusion that prevention should focus on stopping ticks from entering the home in the first place through protective clothing, routine tick checks, and appropriate acaricide use on pets and people.

For veterinary professionals, the study is useful because it sharpens client communication. It supports telling pet parents that an unattached tick dropped indoors may remain viable for days to weeks, not just hours, and that flooring type doesn’t eliminate risk. It also broadens the relevance of prevention beyond Lyme-centered conversations. The paper notes that Gulf Coast ticks are vectors of Rickettsia parkeri and Hepatozoon americanum, while lone star ticks are associated with ehrlichiosis, tularemia, Heartland virus, Bourbon virus, and alpha-gal syndrome in people. In practice, that means indoor tick control counseling should connect companion animal health, household exposure, and zoonotic awareness. (bpb-us-w2.wpmucdn.com)

There are also important caveats. The study used contained, unfed adult ticks under controlled indoor conditions, so real-world survival in homes may vary with humidity, temperature, grooming, cleaning frequency, and whether ticks remain hidden in fabrics or cracks. Even so, the paper gives clinics something they often lack: species-specific, surface-specific data to back up recommendations for year-round prevention, especially in regions where these ticks are expanding or already established. That may be particularly relevant for practices seeing more travel-related exposure, hunting dogs, outdoor cats, or clients who assume winter or indoor settings sharply reduce risk. This is an inference based on the study design and current CDC surveillance, rather than a direct claim from the authors. (bpb-us-w2.wpmucdn.com)

What to watch: The next step will likely be follow-on work testing additional tick species, life stages, and household microenvironments, along with how cleaning practices or indoor humidity affect survival, but for now the immediate impact is likely to be stronger prevention messaging in clinics and public health outreach.
