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.

We are currently seeking neighborhoods to participate in a community-based do-it-yourself tick control project. We are looking for sets of 5-10 contiguous properties of 1/2-1 acre which abut wooded areas.  All homeowners should agree to treatment of the property and be willing to grant access for tick and small mammal collections.  Neighborhoods would be assessed for tick abundance and proximity to untreated (control) sites before enrollment in the project.

The goal is to find low-cost methods that can reduce tick abundance/Lyme disease risk and can be easily performed by individual homeowners or neighborhood groups.  Enrolled neighborhoods would be responsible for applying the treatments to woods and edge habitats. Treatments include methods that target mice (home-made bait boxes or tick tubes) because these are the main source of the disease agents, as well as a barrier treatment with an over-the-counter insecticide or thick mulch path between woods and yard.   We will provide training related to these methods.  We would then visit the community several times over the summer to collect ticks and small mammal samples.  These would be returned to the lab for examination for the Lyme Disease bacterium and other disease agents.  Communities would gain information about the density of infected ticks in the area, infection rates with various pathogens, and tick control methods that might reduce the risk of disease. Please contact Dr. Susan Paskewitz if interested (smpaskew@wisc.edu; 608-262-1696).

Deer ticks are widely distributed in Wisconsin.  Here is a map showing counties where they have been collected through an animal surveillance project.  Most of the white counties are also positive for deer ticks through other surveillance methods.  This means that anywhere in the state where there are woods, deer and mice, the deer tick can now be found.

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.
