RACCOON FACTS
Raccoons (Procyon lotor) belong to the
Procyonidae (those who came before dogs family. This highly
intelligent mammal has a rounded head with short nose, small ears,
and a sturdy body with minimum-length, thick, grayish brown fur.
Raccoons are easily identified by (1) a distinctive pattern of
alternating black and yellowish white rings around a large, bushy
tail and (2) a unique narrow black face mask with two white
patches above the eyes. They average 2 to 3
feet long (including the tail) and 12 inches high, weigh 8 to 22 pounds (heaviest in autumn), and live for 10 to 13 years. Females produce one litter a
year, numbering from one to six kits and averaging four or five.
Over most of the U.S. and southern Canada, except in the
western mountain ranges, raccoons are found in many different
habitats, especially near streams, ponds, and marshes in mature
wooded areas. Their range is expanding further north into Canada,
because of habitat lost to agriculture and the apparent warming of
northern weather. As humans have moved into raccoon habitat, this
mammal has proven more adaptable than most. For nesting sites it
prefers warm, dry, dark, easily protected areas. In the wild, it
dens in tree hollows, hollow logs, or sometimes rocky caverns. In
urban areas, raccoons may nest in drainpipes, basements, crawl
spaces and house attics. Raccoon populations now are actually
densest in suburban and urban areas.
Raccoons will eat whatever their environment provides. In the
rural environment, they eat insects, nuts, worms, frogs,
shellfish, fish, mammals, birds, eggs, grubs, snakes, and fruits.
In agricultural areas, they may feed on corn crops, poultry and
garden and orchard vegetables and fruits. In urban settings, an
easily opened garbage can is hard for them to resist. They are
nocturnal but are occasionally active in daytime.
They are fairly sociable and often den with other raccoons. In
colder regions, raccoons may sleep for a good portion of the
winter; in the summer, they find shady, cool places to rest. They
are territorial with limited private ranges, approximately 1 mile
in diameter. Often their territories overlap with those of other
raccoons but boundary clashes are rare. When confronting each
other, they often grunt threateningly but seldom fight.
The species scientific name, lotor, means the washer,
because raccoons have been observed dunking
their food in water before eating it. This behavior in captivity
is thought to mimic behavior in the wild, where raccoons hunt in
or near water and hold their catch submerged before eating it. In
the wild, they do not wash all food before eating.
Raccoons have keen senses of smell and hearing. They are strong
and agile, hence good tree and fence climbers. Each foot has five
long and slender digits, which operate with remarkable dexterity.
In the wild, they use their front feet for finding food in water,
opening shellfish, and conveying food to the mouth. In adapting to
human habitat, they often apply this dexterity to opening garbage
cans and pet food storage containers.
Zoologists attribute the raccoons adaptability to transmission
of culture, a mammalian trait this creature has developed to a
high level. The young quickly pick up new skills from adults and
then can make their own adjustments or adaptations to new
circumstances.
The raccoons primary enemies are humans, dog packs, traps, and
automobiles. Many would-be larger predators know better than to
take on an adult raccoon, a tough fighter with razor-sharp teeth.
If threatened, the raccoon will often try a counter threat,
fluffing out its fur so that it appears larger and uttering a
throaty growl or cry. Raccoons may appear bold but usually are not
aggressive except during mating season or when defending their
young. However, their strength, teeth, and claws equip them to
defend themselves effectively.
Raccoons are so common that you need not look far for them, and
as their natural habitat shrinks, they are increasingly found in
urban areas. They are night creatures and will be shy in areas
where they are hunted. Where people do not pursue them with rifles
and dogs, they are curious animals. Their tracks are easily
identifiable, looking much like a human handprint.
TIPS
1. Raccoons Raiding Garbage Cans:
Raccoons have learned, through adapting to human
habitat, that garbage cans are excellent sources of food. To raccoon-proof a garbage can, fasten the lid
securely with rope, bungee cords, chain, or even weights. To
prevent cans from being knocked over and rolled around, secure the
handle to a metal or wooden stake driven into the ground. Store
garbage cans in wooden bins or in a shed or garage to limit
raccoon access. As a last effort, place an inch or so of
ammonia-soaked newspaper or rags in the bottom of the garbage can
and sprinkle cayenne pepper on top of the garbage to discourage
raccoons. Handle ammonia carefully, and keep in mind that it is
toxic to children and animals. The ammonia is intended to deter
raccoons with its odor, not to injure them.
2. Raccoons on Porch or in Yard:
Fear of
Threat to Humans or Pets. Raccoons, like humans, are constantly
tending to the basic needs for food and shelter. They find both
near us. While they may be just curious, they are probably in
search of food and usually are not aggressive unless cornered,
mating, or with young. Send them off with a good dousing of water
from the hose or a bucket of water. Instruct and remind children
not to approach, touch or feed them. Raccoons seldom bother cats
unless the cat is territorial and aggressive. Kittens, especially
if out at night, may be seen as prey. Store pet food in heavy-duty
plastic containers with tamper-resistant lids. Try talking to your
neighbors, one of more of whom may deliberately feed raccoons
because they are so cute. Try to discourage this practice by
reminding neighbors not to leave out pet food dishes and to store
pet food securely. Use pet doors at your own risk. Lock them at
night, if possible, or you may be surprised to discover that a
skunk, opossum, or raccoon has invited itself into your home. Some
newer models can be opened only by pets wearing a special magnetic
collar.
3. Raccoons in the House:
Occasionally a
raccoon will find its way into a house through a pet door or
chimney and be unable to find its way out.
A panicked raccoon can
cause extensive damage, so close doors to all other rooms in the
house, open doors and windows to the outside and leave the house.
Wait quietly for the raccoon to find its way out. Do not use food
as a lure; this will make wildlife associate food with humans and
return for more. If the raccoon has not left in a reasonable
period of time, call your local wildlife agency. Only
professionally trained wildlife workers should attempt capture (as
opposed to live-trapping) of raccoons.
4. Raccoons Under the House or Deck:
In
the mating and nesting season, these animals are especially
attracted to warm, dry, dark, and easily defended areas for
temporary homes. The deterrents listed here should never be used
during baby season as they may prevent the mother from
returning, resulting in orphaned, starving babies. Limit and
eliminate access by following these steps:
- Close off all but
one access route to the den area.
- Gather all materials to close
the remaining entrance and place them outside the opening. Sheet
metal works best, or you can use sturdy wire mesh or wood,
hammer, nails, etc.
- Toss ammonia-soaked rags into the space:
the pungent odor annoys the animals with their keen sense of
smell. Check daily to ensure that the odor is present; replenish
as needed. Place small bowls of ammonia on either side of the
entryway; refill daily for at least two weeks. Use ammonia
carefully, however, because it can be toxic to children and to
domestic and wild animals. The aim is strictly to drive away the
raccoon with the odor.
- Brightly light the area, day and night.
This is annoying to nocturnal animals; it is easily accomplished
by taping a mechanics droplight or trouble light to a long
two-by-four and sliding it into the space. Or try placing a
radio near the opening and playing it loudly day and night.
(This may annoy your neighbors more than the raccoons, however.)
- Spread a light layer of flour on the ground outside the
entrance, covering an area large enough to record footprints as
the animals exit. After sunset, begin checking the flour every
45 minutes for exiting tracks. When you see tracks, seal the
opening tightly, unless you hear sounds that indicate the
presence of kits.
- If you do hear kits, leave the access open so
the mother can tend her young; repeat the flour-tracking process
when they begin to follow their mother hunting (at about 8
weeks). Do not approach the den when the mother is inside, as
her protective instinct can make her dangerous.
- If you hear
noise after closing the entrance, determine where it is coming
from. Check outside the blocked entrance as a determined raccoon
will scratch and pull at the barrier to regain access. If the
sound is coming from inside the enclosure, an animal is trapped
inside; reopen the area and repeat the process until all the den
residents have departed.
- Consider live-trapping as the last
alternative. It is rarely a permanent solution, because raccoons
are usually plentiful enough that others will soon replace those
trapped; also, live traps are expensive. Check with local
wildlife agencies regarding live-trapping of raccoons and
appropriate release sites. Never live-trap during baby season.
5. Raccoons in the Attic or on the
Roof:
Attics and roofs can be good nesting locations from a
raccoons point of view. The following deterrents should never be
used during baby season as they may prevent the mother from
returning, resulting in orphaned, starving babies. *Limit access
by following the steps under Raccoons Under the House or Deck.
Unless the roof is easily accessible to you, you may have to
forgo the flour tracking and depend on the other steps. Be sure
to keep replenishing the ammonia until you no longer hear sounds
in the attic; then close the opening. *Remove trellises, vines,
shrubs, tree limbs or other objects that may give animals a
route to the roof or attic.
Wrap tree trunks with 2-foot wide sheet metal, positioning it
at least 2 feet above the ground to prevent raccoons from
jumping over the barrier and climbing trees for access to
buildings. *Replace shingles, repair holes near eaves, and cover
the chimney with heavy mesh wire.
6. Raccoons in the Chimney:
Raccoons
will den in uncapped chimneys and even sometimes bear young
there. They will use the fireplace flue because of the smoke
shelf. *Prevent entry by capping chimneys with a commercial
chimney cap, wire mesh, or other cover. *If a raccoon is in your
chimney, place a small bowl of ammonia at the base of the
chimney so the fumes will carry upward. (Close fireplace doors
or set a barrier across the opening to control odor and prevent
the raccoon from exiting via the house.) Or lower a bag filled
with mothballs or rags soaked in ammonia from the top. Be sure
to leave the top open so the animal can climb out. Make sure
that kits are not in the chimney. If they should be disturbed
(and ammonia should not be used) as this may prevent the mother
from returning.
7. Orphaned Baby Raccoons.
It is normal
for raccoon mothers to leave their young in order to hunt. It is
also normal for kits to whine and cry like puppies. *Unless you
can observe the area for many hours, it is difficult to
determine whether the mother is truly missing or just
temporarily away. If the young cry continuously, with no quiet
periods during which the mother may be feeding them, call
Project Wildlife or another local wildlife agency to get further
information on evaluating the situation.
8. Raccoons in the Garden or Fruit
Trees:
Raccoons are good climbers and relish fruit, but they may
break branches and compete with the growers enjoyment of his or
her crop. Raccoons also like to help themselves to grapes and
corn just before they are ready for picking. *Keep the yard free
of fallen fruit. Wrap a strip of sheet metal (about 2 feet wide)
around the trunk of the tree, positioning it at least 2 feet
above the ground so the animal cannot jump over it and continue
up the trunk. *Use extra vigilance in chasing animals away,
using lights and loud noises, to deter raccoons long enough for
crops to be harvested.
11. Raccoons in Ponds, Hot Tubs, and
Pools:
Raccoons are attracted to water because they associate it
with fish and other prey in the wild. *Cover hot tubs and pools
at night when animals are active. *If the pond isn't too large,
submerge a 2-foot-wide wire mesh horizontally around the edge.
Roll out the mesh, leaving it lightly secured under water.
Raccoons cant reach over the wire and tend not to stand on it
because it is unstable. See also suggestions about the use of
electric fencing in the following section. *If you are so
inclined, leave open access to the pond so the raccoon can share
the water with you.
12. Raccoons Digging Up Garden Plants
and Lawn:
. Raccoons dig in search of worms, insects and grubs
tiny, wormlike larval stages of insects that live in lawns. The
good news is that they wont eat your plants. The bad news is
that they will dig them up to get at the food source in the soil
below.
- Sprinkle lawns or planters with cayenne pepper to
discourage grub hunters.
- Control grub populations so that
raccoons will not be drawn to your lawn in the first place. A
commercial product called Grub Attack is an effective organic
control.
- Fasten bird netting over garden plants. It is easier
for raccoons to dig elsewhere than to remove the netting.
- Improve existing fences by enclosing any open area between the
bottom of the fence and the ground. Or install fence extenders
facing outward at a 45-degree angle on top of each post, with
two or three strands of wire strung between them.
- If the area
is fairly small, try sinking jars filled with ammonia into the
ground, with sponges as wicks. Be sure the jars are anchored in
the soil to prevent spilling. Or hang socks filled with
mothballs.
- Serious gardeners might consider an electrified
fence. String ordinary, 2-millimeter galvanized wire along
insulator posts around the perimeter. The wire should start
about 8 inches above the ground to prevent crawling underneath
and lines should be spaced close together so animals cannot
reach through. Connect the wires to an approved fence charger
with alternating current not exceeding 12 volts, which can be
purchased relatively cheaply at feed stores. Be sure to check
with your local building inspection department for installation
guidelines and/or limitations.
Trapping and relocation of raccoons
is not a recommended or viable alternative. Wild animals are
territorial & like species will simply take over the area
vacated by the relocated or dead animal.
