Warmer weather means you might start seeing gypsy moths.
Crews from the Minnesota Department of Natural Resources put traps out Friday for the invasive species that has taken over oak trees in the state.
The traps are meant to let the DNR know where the moths are invading so they can decide on the best trapping or treatment solution.
Gypsy moths have been in Europe and Asia for thousands of years. They started showing up in America around the 1870s.
