How long does a tick live in clothing? - briefly
Ticks can survive in clothing for up to two weeks under favorable humidity and temperature. In dry, low‑humidity conditions they usually die within five days.
How long does a tick live in clothing? - in detail
Ticks can remain viable on clothing for several weeks under favorable conditions. Their survival depends primarily on temperature, humidity, and whether they have fed.
-
Temperature: At 20‑25 °C (68‑77 °F) ticks stay active for up to 30 days. Below 10 °C (50 °F) metabolic activity slows, extending lifespan to 60 days or more, but they become dormant. Temperatures above 35 °C (95 °F) reduce survival to a few days.
-
Humidity: Relative humidity above 80 % prevents desiccation, allowing ticks to persist for the full temperature‑dependent period. In dry environments (≤50 % humidity) survival drops to 7‑10 days.
-
Feeding status: Unfed nymphs and adults can survive longer than engorged individuals. Engorged ticks lose water quickly and typically die within 3‑5 days if left on fabric.
-
Species variation:
– Ixodes scapularis (black‑legged) tolerates lower humidity, surviving up to 45 days on moist clothing.
– Dermacentor variabilis (American dog tick) requires higher humidity, lasting 20‑25 days under optimal moisture.
– Amblyomma americanum (lone‑star) endures warmer conditions, persisting 15‑20 days at 30 °C with adequate humidity. -
Fabric type: Synthetic fibers wick moisture away, creating drier microenvironments that shorten tick lifespan. Natural fibers such as cotton retain humidity, supporting longer survival.
-
Removal and prevention: Immediate shaking, laundering at ≥60 °C, or tumble‑drying for 30 minutes eliminates ticks. Regular inspection after outdoor activities reduces the risk of prolonged exposure.
In summary, a tick can live on garments from a few days to two months, governed by ambient temperature, moisture level, species traits, feeding state, and fabric characteristics. Proper hygiene and environmental control are essential to minimize the duration of viability.
