Located in Wisconsin’s Fox Valley, Appleton’s mix of wooded parks, river corridors, tall grasslands, and suburban neighborhoods creates an ideal environment for ticks. The area’s warm summers, cool spring rains, and mild-to-moderate winters support several tick species that remain active for much of the year.
Ticks in Appleton typically begin appearing in April, peak in May–August, and remain active until the first hard freeze in late fall. Understanding which species are most common in the region helps residents protect themselves, their families, and their pets during the warmer months.
