Raccoon mating season generally kicks off in late winter and runs into early summer, with the heaviest activity around February and March. The exact window shifts a bit by region, warmer areas start earlier and stretch later. During this stretch, males roam farther than usual looking for mates, and females start hunting for a safe den, which is where your attic or chimney comes in.
The timeline
- Late winter to early spring: males start moving around more, fighting and calling.
- February and March: peak mating, and the noisiest stretch.
- Spring: pregnant females look for den sites, and attics and chimneys are prime targets.
- Spring into summer: litters are born. Gestation runs about 63 days, and a typical litter is a few kits.
- Late summer into fall: the young start exploring and then go independent.
Behavior during mating season
- More noise. Males chatter, hiss, and growl while competing.
- More daytime activity. Males travel farther than usual and may show up at odd hours.
- More damage. Males tear at roofing, siding, and vents trying to reach a potential den.
- Protective mothers. A female with kits will defend the den, so give them space.
Males reach breeding age around one year old, but younger ones often get out-competed by bigger, older males and may not actually breed right away. Females raise the litter alone, and the male takes no part in it.
If there are babies
A litter is born blind and helpless, and the mother keeps them in the den for weeks. They stay with her through their first winter in a lot of cases.
If you find baby raccoons, leave them. The mother is probably close by and will come back. If you are sure she is gone, call a wildlife rehabilitator rather than trying to raise them yourself.
Prevention
The best time to raccoon-proof is late fall, before mating season starts. Seal entry points with hardware cloth, cap the chimney, trim branches away from the roof, and remove food sources like unsecured garbage and pet food. Once a female has denned with kits, you usually have to wait until the young are mobile before you exclude them, so preventing it in the first place is the easier path.
Frequently Asked Questions
Generally from late winter through early summer, peaking around February and March. The timing varies by region and climate.
No. They are not monogamous. A male mates with several females, and the female raises the litter alone.
A typical litter is a few kits, usually three to five or so. A female has one litter a year, though she may breed again if an early litter is lost.
Males get more aggressive competing for mates, and mothers get protective of their dens. Give them extra space during this stretch.
