Adult deer ticks are looking for hosts now. On Oct 26, 2013, we collected 171 adults in a site between Spooner and Rice Lake. On Oct 19, we collected 41 adults, a few nymphs and some larvae at a site between Madison and Milwaukee. Citizens and veterinary partners who are helping us by collecting ticks are also sending and reporting high numbers of adults. We estimate that, on average, 30-50% of the adults will be infected with the Lyme disease spirochete. Remember to do tick checks after you’ve been outside.

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.
