March 13, 2024: Our colleagues at the Department of Health Services just received a photo of a nymphal deer tick that was found this week in southern Wisconsin. That's earlier than the record we set last year in April, by 1 full month.
March 12 , 2024: We've been collecting adult deer ticks for at least a month now because of the warm temperatures. It looks like the risky months will be expanded this year. So please use your tick prevention methods-do a tick check, take a shower soon after being outside, throw your clothes in a hot dryer and use a repellent.
2024: IT’S HERE! Tick season has begun and it is early this year. Lots of people are picking up adult deer ticks on themselves and pets because it has been so warm. They usually get active above about 40F. We even have a report of 1 nymph from the week of March 11. Remember to do your tick checks-adults are relatively easy to feel and remove.
2024: The Tick App now has a Spanish version. We are excited to expand the Tick App to new audiences 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.
