Updates
May 2023: It's National Lyme Awareness month. As we move into the period when ticks are active, keep an eye out for symptoms like an unexplained large and expanding rash or "summer flu". Check with your physician if you might have been in tick habitat.
April 2023: We just got the earliest nymph we've collected in the state (April 14). Please remember to take precautions!
January 2023: It's unseasonably warm so adult ticks may be active when you don't expect it. Adult deer ticks can be actively looking for a host when temperatures are in the low 40s (or even lower when in a sunny spot). Be sure to check for ticks if you've been in snowless areas and might have brushed the vegetation.

FOR 2023: We are excited to expand the Tick App to provide reminders about prevention strategies! The Tick App is a smartphone application to study human behavior, tick exposure and the risk of Lyme disease by collecting data through simple surveys with a citizen science approach.


Nymphal deer ticks can be in your lawn. We found lots of them in mowed grass near woods while sampling at home sites in Eau Claire, Wisconsin and near Mirror Lake.
