This year's tick season in Finland has commenced earlier than usual, with reports indicating the first tick sightings have been made by mid-March, particularly in the vicinity of Oulu. Almost a hundred observations have been recorded across the country in the past month, contributing to the database maintained by Turku University and pharmaceutical company Pfizer.

Professor Marko Mutanen from the University of Oulu's molecular systematics and biological literacy department highlighted the unusual timing of the tick season's emergence. Typically, ticks are known to awaken in early spring; however, he noted that starting the season by mid-March is not the norm and indicates a shift in environmental conditions that may be affecting these creatures.

The early awakening of ticks is attributed to the lack of snow coverage and the warmer weather across Finland. Ticks hibernate in the underbrush and typically become active once the ground is clear of snow and temperatures rise above a few degrees Celsius. With temperatures reaching 5 to 6 degrees, the absence of a snowy landscape has allowed ticks to emerge earlier than expected, raising concerns regarding the potential for increased tick-borne diseases this season.
