Short answer

Ticks can orient to combinations of host odour, carbon dioxide, heat and movement, although responses differ among species.

At a glance

Ticks can orient to combinations of host odour, carbon dioxide, heat and movement, although responses differ among species. Behaviour changes with species, life stage, temperature, humidity and host cues, so one observation rarely predicts every tick.

Key takeaways

• Ticks can orient to combinations of host odour, carbon dioxide, heat and movement, although responses differ among species.

• Behaviour changes with species, life stage, temperature, humidity and host cues, so one observation rarely predicts every tick.

• Apply this information with current official guidance and the actual circumstances; use qualified medical or veterinary help when removal, symptoms or safety are concerning.
