Kicking off the second half of May, tick season returns to Door and Kewaunee Counties. The area is classified as being under a moderate threat for the worst tick-borne illness, Lyme disease. Door County Public Health Sanitarian Chelsea Smies says the insects are most prevalent in brush.
Record low temperatures mid-week have helped rein in grass and foliage growth. Ticks are not able to survive hard frosts and freezes, something seen by most areas in the Door Peninsula outside of the lakeshore. That may keep the parasites at bay longer than average this spring.
