How long can a tick live on clothing? - briefly
Ticks can survive on fabric for a few days to about two weeks, with longevity determined by humidity and temperature. In dry, indoor environments they typically die within 48–72 hours.
How long can a tick live on clothing? - in detail
Ticks that attach to garments can remain alive for several days, but the exact period depends on species, temperature, and humidity. Under optimal conditions—moderate warmth (15‑25 °C) and relative humidity above 80 %—adult ticks of the black‑legged species may survive up to 10 days. When the environment is cooler (5‑10 °C) or drier (humidity below 50 %), survival drops to 2‑4 days. Larval and nymph stages are more vulnerable; they typically endure 1‑3 days under similar conditions.
Key variables that determine longevity on fabric:
- Temperature: Survival time shortens markedly below 5 °C or above 30 °C.
- Humidity: Dry air accelerates desiccation; high moisture extends life.
- Species: Dermacentor variabilis (American dog tick) tolerates lower humidity and can last 5‑7 days, whereas Ixodes ricinus (European castor bean tick) requires higher moisture and survives 3‑5 days.
- Clothing material: Synthetic fibers wick moisture away, reducing humidity around the tick; cotton retains moisture, potentially lengthening survival.
Indoor storage further limits duration. In a heated, air‑conditioned room with typical indoor humidity (30‑50 %), most ticks die within 24‑48 hours. Exposure to direct sunlight or a tumble‑dry cycle at high heat (>60 °C) kills them instantly.
Practical measures:
- Remove and shake clothing immediately after outdoor activity.
- Wash garments in hot water (≥60 °C) and tumble‑dry on high heat for at least 10 minutes.
- Store unused clothing in sealed containers to prevent accidental contact.
Understanding these parameters helps assess risk and implement effective control after exposure to tick‑infested habitats.
