Raccoons are active year round, but certain times of the year see spikes in their behavior that impact homeowners more noticeably. “Raccoon season” generally refers to spring and early summer when breeding and denning occur. Understanding raccoon season helps homeowners prepare for the times of year when raccoons are most likely to invade attics, chimneys, or sheds in search of shelter for raising their young.
Raccoons mate in late winter through early spring, typically January through March. During this period, males travel long distances searching for females, increasing sightings and encounters with people. After a gestation period of about two months, females give birth in spring, usually between April and June. Litters average 3 to 5 kits, and mothers aggressively seek safe dens to raise their young.
Spring and early summer mark peak denning season. Mothers use attics, chimneys, or crawlspaces to protect their kits. This is when homeowners are most likely to hear noises at night or discover signs of raccoon entry. Because mothers are protective, removal during this time should be handled by professionals to avoid separating families or creating dangerous encounters. Wildlife experts can safely reunite young with their mothers or time removal for after the denning season, ensuring humane and effective solutions. Attempting DIY removal during this sensitive period often leads to property damage and increased risks for both people and animals.
In fall, raccoons increase feeding to build fat reserves for winter. While they do not hibernate, they enter periods of reduced activity during the coldest months, relying on dens for warmth. Activity spikes again in spring when breeding begins anew. These cycles explain why raccoon activity seems to surge at predictable times each year.
Knowing raccoon season allows homeowners to take preventive steps such as sealing entry points before spring or fall. Monitoring activity during these high risk periods reduces the chance of infestations. Professional exclusion is especially important before breeding season to avoid complicated removals involving young kits.
