This site will provide information on ticks and tick-borne disease in Wisconsin. Please use the drop-down menus above to find the information most relevant to you.
What’s new? We’ve added maps with data on the distribution of deer and wood ticks in Wisconsin and on the infection rates of deer ticks for Anaplasma phagocytophilum, Ehrlichia, and Babesia microti.
Figure 1. Adult deer ticks (top row) and wood ticks (bottom row). Females are on the left and males on the right.
These are male and female lone star ticks (Amblyomma americanum). We are interested in receiving specimens that were picked up in Wisconsin, especially if the approximate location can be identified. Please contact firstname.lastname@example.org if you find one. See the page on Amblyomma under Wisconsin ticks for more information.
