Raccoons are nuisance animals that can become aggressive and spread disease to humans and pets. They are active year round but can be most destructive in late winter and early spring as they seek nesting or denning areas in which to birth their young.
- Raccoons are stocky with short front legs and long back legs.
- Adults are 20 to 30 inches long and weigh 10 to 35 pounds.
- They have grayish-black fur, rounded ears, and a distinguishing black "mask" over the eyes.
- They are very furry with a striped tail, having alternating light and dark rings.
- These mammals are very common throughout the United States.
- Raccoons are very intelligent. According to the Maryland Department of Natural Resources, studies have shown that these mammals can remember how to solve tasks for up to three years.
- Raccoons are a nocturnal animal and are active year-round.
- They make their homes:
Natural dens – in wooded areas along streams, lakes, marshes, swamps, and farmland in hollow trees, ground burrows, brush piles, or rock.
In cities/suburbs – in backyards, beneath decks, or in outbuildings, such as sheds, barns or abandoned buildings.
In houses – in attics, chimneys, and the spaces beneath the home or porch
- Like many wildlife, raccoons have their young in the spring, generally having. litters of 3 to 6 babies, or "kits."
- The kits stay with their mother for the first year, then begin to leave as new young are born the following spring.
- They are omnivorous, eating just about anything. Preferred food includes:
- Plants: fruits, plums, gooseberries, blackberries, blueberries, dogwood berries, wild cherries, currants, wild grapes, apples, hawthorns, acorns, hazelnuts and beechnuts, corn, grains.
- Animals: crayfish, clams, fish, frogs, snails, insects, turtles, rabbits, muskrats, eggs and young of ground-nesting birds, turtle eggs.
- Human foods: garden fruits, nuts, and vegetables, outdoor pet food, garbage and compost scavenging, bird feeder grains.
- To feed, raccoons use the well-developed sensory nerves on their paws to feel their food and remove unwanted parts.
Raccoon Damage & Disease
Raccoons can cause a great deal of damage to homes and yards and be threatening to human health, including:
- In gardens and yards – Raccoons will eat garden vegetables and fruit; they will raid trash cans and eat pet food that is left outside.
- To home exteriors – Raccoons will rip off shingles, fascia boards, rooftop ventilators, and crawlspace doors to get into the home (particularly attic and crawlspace) to nest.
- To home interiors – They will use insulation for nesting, and urinate and leave feces in the areas in which they den, leaving parasites and foul odors.
- To people and pets – Raccoons carry diseases and parasites. They can spread rabies as well the raccoon roundworm to people. Both can cause serious problems or disabilities, particularly to young children. Raccoons can also spread canine distemper and parvovirus to dogs.
