Short answer

Some ticks can survive cold periods by sheltering in leaf litter, soil, animal nests or protected buildings. Survival varies greatly by species and local conditions.

At a glance

Cold weather may reduce activity without killing every tick. A warm spell or sheltered microclimate can permit activity when the wider weather feels wintry.

Key takeaways

• Cold does not guarantee that ticks are absent.

• Sheltered microclimates matter.

• Seasonal patterns differ by species and region.

Weather is not the whole habitat

Conditions beneath leaves or close to the soil can differ from the air temperature reported nearby. Snow cover and animal shelters may also buffer some ticks from extremes.

Avoid universal claims

Cold tolerance differs among species and life stages. Use regional surveillance and public-health advice rather than assuming that a particular temperature makes every location tick-free.
