What Time of Year Do Raccoons Have Babies in Wisconsin?
Raccoons mate in late winter from January through March. After a gestation period of about 60 days, most litters are born in April and May. However, births can occur as early as March or as late as June, depending on how mild or severe the winter is.
A female raccoon usually gives birth to a litter of 2 to 5 kits. These newborns are completely dependent on their mother for the first several weeks and remain in the den until they’re strong enough to explore on their own. If you start hearing chirping, chattering, or scratching noises overhead during this time of year, there’s a good chance you may have an unexpected raccoon family.
Common Signs You Have Raccoons in Your Attic
Raccoons are noisy, destructive, and quick to make themselves at home in attics. Recognizing the early signs can help you address the problem before serious damage occurs.

- Damaged roof shingles, vents, or soffits.
