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.
Tick testing: We frequently receive requests for tick testing. While we don’t perform this service, you can find commercial operations that will do this for a fee at the Tick Encounter Resource http://www.tickencounter.org/tick_testing.
Larval and nymphal deer ticks are active now (July 2015)! Both deer and wood ticks are actively looking for hosts. Remember to do careful tick checks if you’ve been in tick habitat. And watch out for the tiny nymphal deer ticks, which are likely responsible for much of the disease transmission. Numbers of nymphs are usually highest in June and early July.

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 email@example.com if you find one. See the page on Amblyomma under Wisconsin ticks for more information.
