“Ticks have been active for quite a while now,” said P.J. Liesch, the director of the University of Wisconsin-Madison Insect Diagnostic Lab. “It’s something that can often catch folks off-guard. We might not be thinking about ticks in those winter months — January, February, March — but once temperatures get above freezing consistently and we maybe hit 40-degrees with no snow on the ground, ticks can be active.”
