Welcome

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.

Adult deer ticks are active now (March, 2016) and will be out until mid-Summer.  In prior years we’ve also picked up nymphs in March and April, so even the smaller stages may be out there.

AMB AME MALE & FEMALEThese 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 smpaskew@wisc.edu if you find one.  See the page on Amblyomma under Wisconsin ticks  for more information.
