When chiggers are busiest in Wisconsin

The Wisconsin Extension guide covers chiggers as a warm-season outdoor hazard alongside ticks and biting flies but does not assign specific months to chigger activity.

After exposure Extension recommends a hot, soapy bath or shower as soon as possible, a vigorous towel rubdown to remove unattached larvae, and washing all clothing before wearing it again.
