At a glance

Peak seasons are useful for awareness campaigns, but they are not hard boundaries. Exposure can occur outside the expected season.

Key takeaways

• Mild winter days can support activity.

Season is local

Latitude, altitude, humidity, vegetation and host activity all influence when ticks quest. A calendar created for one country or species may be misleading elsewhere.
