This has been the coldest winter since 1980 and we don’t know what impact that will have on tick survival. I predict that the lone star tick-which we have begun to see in greater numbers here in Wisconsin-will be wiped out in our state. Conversely, deer ticks are adapted to cold conditions so there may be little impact. But many experts predicted that 2012 would be a record year for ticks and Lyme because of the early warm season (it wasn’t a record year anywhere) and I predicted that 2013 might be a low-tick year in Wisconsin because of the 2012 drought (we actually saw higher numbers at all sites for which we have records). So, for this year’s cold weather impacts, we’ll have to wait and see what the spring brings.

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.
