Quick Answer
Ticks can survive in cold climates, but their activity level decreases significantly below 40°F (4°C). In temperatures below 32°F (0°C), ticks are typically immobile and unable to feed.
Tick Survival in Cold Climates
Ticks can survive for several months in cold temperatures by entering a state of dormancy called diapause. During this time, their metabolic rate slows down, and they rely on stored energy reserves. The duration of diapause depends on the species of tick and the temperature, but it can last anywhere from a few weeks to several months.
Cold-Resistant Tick Species
Some tick species, such as the winter tick (Dermacentor albipictus), can survive for up to 18 months in cold temperatures. The American dog tick (Dermacentor variabilis) can survive for up to 12 months. The blacklegged tick (Ixodes scapularis) and the lone star tick (Amblyomma americanum) can survive for up to 6 months.
Tick Removal in Cold Climates
When removing ticks in cold climates, it’s essential to use a fine-tipped pair of tweezers to grasp the tick as close to the skin as possible. Slowly and steadily pull upward with steady, even pressure. Do not twist or jerk the tick, as this can cause the mouthparts to break off and remain in the skin, increasing the risk of infection. After removal, clean the bite area with soap and water and apply an antiseptic.
