A team of University of Wisconsin-Madison scientists recently surveyed Doctors Park in Bayside for the presence of deer ticks and found evidence suggesting that ticks were not just present in the county, but were living and reproducing there, too.”As far as I know, this is the first demonstration of an established population in Milwaukee County, although ticks have been getting closer and closer,” said Susan Paskewitz, a UW professor of entomology who led the survey.
