themselves, the skunk advertises its identity with its
bold coloration. Most predators need only one lesson to
learn to avoid the skunk at first sight of black-and-white.
As shown here with a badger, the striped skunk has two
prominent white stripes running down its back.

Skunks are mild-tempered,
mostly nocturnal, and will defend themselves only when cornered
or attacked. Even when other animals or people are in close proximity,
skunks will ignore the intruders unless they are disturbed.
Skunks are
beneficial to farmers, gardeners, and landowners because they feed
on large numbers of agricultural and garden pests. While young skunks
are cute and kittenlike, they are wild animals and it is illegal
to keep them as pets (see "Legal Status").
Two skunk species
live in Washington: The striped skunk (Mephitis mephitis,
Fig. 1) is the size of a domestic cat, ranging in length from 22
to 32 inches, including its tail. Its fur is jet black except for
two prominent white stripes running down its back. The striped skunk
occurs throughout most lowland areas in Washington, preferring open
fields, pastures, and croplands near brushy fencerows, rock outcroppings,
and brushy draws. It is also seen—or its musky odor noticed—in
some suburban and urban locations, particularly near sources of
open water.
The spotted
skunk (Spilogale putorius, Fig. 2), also known as the
civet cat, ranges in length from 14 to 18 inches, including its
tail. Its fur is a black or grayish black, with white stripes on
its shoulders and sides, and white spots on its forehead, cheeks,
and rump.
The spotted
skunk occurs throughout west and southeast Washington. The spotted
skunk and striped skunk use similar types of habitat, although the
spotted skunk is more likely to be seen in and around forests and
woodlands, and is not as tolerant of human activity as the striped
skunk.
Facts
about Washington Skunks
Food and
Feeding Habits
|
|
| Figure
2. Two skunk species found in Washington State. The
striped skunk on the left, and the spotted skunk or civet
cat on the right. |
- Skunks
will eat what they can find or catch. They have large feet,
well-developed claws, and digging is their primary method used
to obtain food.
- Some of
their favorite foods include, mice, moles, voles, rats, birds
and their eggs, and carcasses—also grasshoppers, wasps,
bees, crickets, beetles, and beetle larvae.
- Skunks
also eat fruits, nuts, garden crops, and scavenge on garbage,
birdseed, and pet food.
- Skunks
will roll caterpillars on the ground to remove the hairs before
eating them. They will also roll beetles that emit a defensive
scent, causing the beetle to deplete its scent before they eat
it.
Den
Sites
- Skunks
use underground dens year-round for daytime resting, hiding,
birthing and rearing young.
- Dens are
located under wood and rock piles, buildings, porches, and concrete
slabs—also in rock crevices, culverts, drainpipes, and
in standing or fallen hollow trees.
- Skunks
may dig their own dens, but more often use the deserted burrows
of other animals, such as ground squirrels and marmots.
- Dens are
either permanent, or used alternately with other dens.
- Spotted
skunks are excellent climbers and may use an attic or a hayloft
as a den.
- Skunks
do not hibernate; instead, they lower their body temperature
and stay inside their dens during extreme cold, plugging the
entrance with leaves and grass to insulate them from the cold.
- Female
skunks sometimes share communal dens.
Reproduction
- Striped
skunks breed from February through March. Spotted skunks breed
from September through October and experience delayed implantation;
the fertilized egg does not attach to the uterine wall for a
period of time after breeding.
- In late
April and May, females of both species give birth to four to
five young in an underground nest lined with dried grass and
other vegetation.
- At around
60 days of age, the mother leads her young out at dusk to forage
and hunt. At three months old the skunks are almost full-grown
and completely independent.
- Striped
skunk families often remain together throughout the winter.
Mortality
and Longevity
- Skunks
have few predators—hungry coyotes, foxes, bobcats, and
cougars, also large owls (which have little sense of smell).
Domestic dogs will also kill skunks.
- Skunks
also die as a result of road kills, trapping, shooting, and
killing by farm chemicals and machinery.
- Striped
skunks live three to four years in the wild; spotted skunks
live half that long.
Signs
of Skunks
Signs of skunks
include their tracks, droppings, and evidence of their digging.
A musky odor is another sign of their presence. A persistent smell
and freshly excavated soil next to a hole under a building or
woodpile indicates that a skunk may have taken up residence.

Figure
3. Striped skunk tracks average 2 inches long by 1 inch
wide. The tracks of spotted skunks are similar, but smaller.
The long nails of the front foot are the skunk’s identifying
feature.
(From Pandell and Stall, Animal Tracks of the
Pacific Northwest) |
Skunks usually
begin foraging after dark and are back in their dens before daylight.
While striped skunks are sometimes seen during the day, spotted
skunks seldom are—they may not even venture out on bright
moonlit nights.
Skunks search
for food along established routes and have a home range of less
than 2 miles. Since they commonly patrol country roads looking
for road-killed animals, vehicles often hit them.
When around
skunks, avoid making loud noises, moving quickly, or taking other
steps that could be interpreted by the skunk as a threat. If the
skunk appears agitated, retreat quietly and slowly.
Skunks have
poor eyesight and will often approach people who are standing
still. If this happens, slowly move away from the approaching
skunk.
Tracks
Skunk tracks
can be found in mud, dirt, or snow around den sites and feeding
areas (Fig. 3). Skunk tracks look like domestic cat prints, except
they show claw marks and five toes, not four. Unlike cats, skunks
can’t retract their claws, so each of their toe pads has
a claw mark in front of it. Skunk tracks are also usually staggered,
unlike domestic cat prints, which are often on top of each other.
Droppings
Look for droppings
where skunks have been feeding or digging, or near a den. Droppings
look like those of domestic cats and contain all types of food,
from insect skeletons, to seeds or hair. Striped skunk droppings
are ½ inch in diameter, 2 to 4 inches long, and usually
have blunt ends. Spotted skunk droppings are similar looking,
but half the size.
Getting
Skunked |

Figure
4. The spotted skunk has white stripes on its shoulders
and sides, and white spots on its forehead, cheeks, and
rump. When forced to, it will adopt a defensive posture
of standing on its front feet with its hind feet and tail
in the air.
(From
Christensen and Larrison, Mammals of the Pacific Northwest:
A Pictorial Introduction.) |
In other
animals, musk is used for scent-marking and courtship. Only
the skunks have turned musk into olfactory muscle. When an adult
skunk or its young are threatened, they may emit a musky fluid
from a nozzlelike duct that protrudes from the animal’s
anus. This fluid—nature’s version of tear gas—can
be discharged either in a fine mist or in a water-pistol-type
stream. It has a stifling, pungent, often gagging odor that
can persist for weeks and be detected over a mile away. On a
still day, a skunk can discharge musk 12 feet with good accuracy.
On a windy day, spray may reach a person standing downwind 18
feet away or more. Because even a few droplets of skunk spray
smell so strongly, it doesn’t take a direct hit to pick
up the odor.
People’s reaction to the odor varies greatly. Almost
everyone finds it intolerable when in high concentration.
Some people become violently ill. Low levels of the odor are
still repugnant to most, while a few find them bearable or
almost pleasant.
Because
skunks have a limited supply of ammunition, they don’t
waste their defensive spray. A striped skunk can fire five
to eight times before it has to reload, which takes about
a week.
Fortunately
skunks have various ways of warning when they are threatened,
giving an intruder ample opportunity to back off. Dogs, however,
tend to ignore this warning. That’s why it’s hard
to find a human who has been sprayed, but easy to find a dog
that has!
Contrary
to popular myth, a striped skunk cannot spray over its back.
When threatened it will stomp its front feet and, if the threat
continues, it will make short charges with its tail raised
in the direction of the threat. Next, the skunk will twist
its hind end around so it is headed in the same direction
as its snout. If the sunk continues to feel threatened, it
will then spray.
Musk
produced by spotted skunks is more pungent than that of striped
skunks. However, they are less likely to spray, and will climb
a fence post or a tree when threatened. When forced to, a
spotted skunk will stand on its front feet with its back arched
so that the spray is discharged forward (Fig. 4).
The odor-bearing
fluid, or musk, is amber in color, oily, and only slightly
volatile. Therefore, it goes away “on its own”
very slowly. However, it will go away eventually (perhaps
in two to four months), even if nothing is done to get rid
of the odor. This natural process is greatly slowed in areas
with little ventilation and when the musk has penetrated porous
materials.
If a
person or pet is sprayed, the quicker you do something about
it the more completely you can remove the odor. First, if
eyes get irritated, flush them liberally with cold water.
Next, because skunk spray is highly alkaline, counteract this
by washing with mildly acidic substances such as carbolic
soap, tomato juice, diluted vinegar, or the following home
remedy:
- 1
quart of fresh, 3 percent hydrogen peroxide solution (old
HP eventually turns into water)
- ¼
cup of baking soda (bicarbonate of soda)
- 1
teaspoon of a liquid soap that is known for its degreasing
qualities
Always
mix the solution in a large, open container. A closed container
can explode. The mixture will bubble because of the chemical
interaction between the baking soda and the hydrogen peroxide.
Use the entire mixture while it is still bubbling. Wearing
rubber gloves, apply the solution, work it into lather, and
leave it on for 30 minutes.
Commercial
preparations containing “neutroleum alpha,” available
from some pet stores, are also effective.
After
washing with any remedy solution, follow with a long hot shower.
Depending on the severity of the spray, you may have to repeat
the process two or three times.
These
solutions may be used to eliminate most of the skunk odor
from people and pets. When washing a dog, wash the body first
and then the head to keep the dog from shaking off the mixture.
This will make the odor tolerable—only time will eliminate
it.
Depending
on the severity of the spray, clothing may be soaked in a
weak solution of household chlorine bleach, ammonia, or products
containing neutroleum alpha. If the clothing has been heavily
sprayed, however, your best option may be to discard or burn
it, because fabric will hold the skunk odor for a long time.
The above
products may also be used to clean odor from inanimate objects.
If the odor is inside or under your house, the area will need
to be thoroughly aired out. Using fans will help.
Never
use bleach or ammonia, at any dilution, on pets. Never use
bleach or ammonia on materials you do not want to stain or
discolor.
And remember . . . the best remedy is Don’t
Get Sprayed! |
Den
Entrances
Look for a
grass-free, smooth, 3 by 4 inch depression under a woodpile, shed,
porch, or similar place. Generally, you will find only one entrance
and a musky odor will be noticeable. Two-inch long black or white
hairs may be found lodged in wood or other rough surfaces surrounding
the entry.
Digs
Skunks
dig in lawns and other grassy areas; usually several holes appear
in the same few square yards. When searching for insect grubs,
skunks make small holes 1 to 3 inches in diameter and deep. (Such
holes are similar to those made by Eastern
gray squirrels.) Larger holes in rougher grass may be evidence
of skunks digging for voles or other rodents. Skunks also tear
apart logs and dig up nests of wasps and other insects in search
of a meal.
Preventing
Conflicts
| Figure
5. Various ways to install a barrier to prevent skunks
(and other burrowing mammals) from digging under concrete
slabs, decks, chicken coops, and similar places. To add to
the life of any metal barrier, spray on two coats of rustproof
paint before installation. Always check for utility lines
before digging in an area. |
|
a.
Lay large flat stones, concrete patio pavers, or ¼-inch
hardware cloth (held in place with stakes) on the surface
of the soil next to a concrete slab or wall. The barrier
forces animals to begin digging farther out and they will
most likely give up in the process. |
|
b.
Bend hardware cloth into an “L” shape and lay
it in a trench so that the wire goes at least 1 foot below
ground and 1 foot out from the concrete slab. |
|
c.
Excavate a 3 x 3 inch trench along the side of the slab
or wall, and hammer 2-foot lengths of rebar, spaced a few
inches apart, into the ground. Cover the tops with concrete
or dirt.
(Drawings by Jenifer Rees.) |
Even though
skunks possess a powerful spray defense, they will not spray unless
surprised, cornered, harmed, or they need to protect their young.
Young skunks are more likely to spray than more experienced skunks.
Occasional
skunk sightings in a neighborhood need not be cause for alarm.
Because skunks are nomadic, most concerns about them being under
sheds, porches, and outbuildings are resolved in due time: skunks
just move on.
The most
effective way to prevent conflicts is to modify the habitat around
your home so as not to attract skunks.
Do not
feed skunks.
Doing so may create undesirable situations for you, your children,
your pets, and the skunks. Skunks that are artificially fed often
lose their fear of humans. Artificial feeding also tends to concentrate
skunks in a small area, and overcrowding can encourage diseases
or parasites. Finally, these skunks might drop in on neighbors
who do not want them around. These same neighbors might decide
to have the skunks removed.
In addition,
feed dogs or cats inside or clean up any spilled or uneaten food
before dark, place indoor pet food or other food away from a pet
door, and put food in secure compost containers. Also, regularly
clean up bird feeding stations. (See the handout "Preventing
Problems at Bird Feeders" for detailed information on
managing bird feeding stations.)
Prevent
access to denning sites.
Skunks frequently den under houses, porches, sheds, and similar
places. Close off these areas with ¼-inch hardware cloth,
boards, metal flashing, or other sturdy barriers. Make all connections
flush and secure to keep mice, rats, and other small mammals out.
Make sure you don’t trap an animal inside when you seal
off a potential entry (see Evicting Animals
from Buildings). To prevent skunks from digging under a building
or concrete slab, install a barrier (Fig. 5).
Enclose
ducks and chickens in a secure coop at night.
A skunk may dig or otherwise find its way into a chicken coop
and kill one or two small fowl, but if several chickens or ducks
have been killed at one time, the predator is more likely a weasel,
mink, fox, raccoon, or bobcat. If a skunk is eating the eggs of
chickens or ducks, you will usually find eggs opened on one end
with the edges crushed inward. A skunk cannot easily carry or
hold chicken-sized eggs; therefore, the eggshells are rarely moved
more than 3 feet from the nest.
To prevent
skunks from digging under the coop or pen, create a barrier (Fig.
5). For further information, see "Preventing
Conflicts" in Raccoons.
Protect
your pets.
To keep pets from being sprayed, keep them inside at night.
Prevent
damage to lawns.
Because lawns—especially newly created ones—are often
heavily watered, worms and grubs inhabit areas just under the
sod, attracting skunks (and raccoons). Skunks tend to dig 1- to
3-inch deep holes only where a grub is located; raccoons tend
to roll or shred the sod in their search. The use of pesticides
to kill worms and grubs is not recommended because of their toxic
effect on the environment, people, and animals.
To prevent
digging, lay down 1-inch mesh chicken wire, securing the wire
with stakes or heavy stones or heavy objects. Alternatively, sprinkle
cayenne pepper or a granular repellent, such as Repel®—a
commercial dog and cat repellent available at most pet stores
or garden centers—over small areas during dry weather.
Surrounding
the area with a low chicken-wire fence used to prevent rabbit
damage can protect large areas from striped skunks. (See "Preventing
Conflicts" in Rabbits for a
fence design). To prevent spotted skunks from climbing, use the
mini floppy fence described under "Preventing
Conflicts" in Mountain Beaver.)
A temporary, single strand of electric wire 5 inches above the
ground will also deter skunks (see "Electric
Fences" in Deer).
Skunks
in or Under Buildings
Occasionally
a skunk will find a suitable den site in or under a building.
Skunks normally occupy a den site for only two or three consecutive
nights. However, during the mating and nesting season, females
are attracted to warm, dry, dark, easily defended areas, and will
remain longer if the setting remains favorable.
You may choose
to let skunks occupy an area, such as under an outbuilding, if
they don’t pose a problem. Should you choose to remove the
animals, a wildlife control company can be hired (see Hiring
a Wildlife Control Company), or you can complete the process
yourself (see Evicting Animals from Buildings.)
If a skunk
finds its way into your house, garage, or other structure, stay
calm, close all but one outside door, and let the animal find
its own way out. If necessary, you can slowly encourage the skunk
to move in a preferred direction while holding a large towel,
or a large piece of plastic or cardboard in front of you. If the
skunk appears agitated, retreat immediately. Don’t use food
as a lure—this will make the animal associate food with
humans, and return for more. If the skunk appears sick or injured,
call a nearby wildlife rehabilitator for assistance (see Wildlife
Rehabilitators and Wildlife Rehabilitation for information).
Trapping
Skunks
If all efforts
to dissuade problem skunks fail, you may feel the need to trap
the animals. Trapping skunks should be a last resort and can never
be justified without first applying the above-described preventative
measures. Trapping is also rarely a permanent solution since other
skunks are likely to move into the area if attractive habitat
is still available.
A wildlife
damage control company can be hired to do the trapping, or you
can do it yourself (see Hiring a Wildlife
Damage Control Company). It is usually best to let someone
with experience trapping skunks do the work. Because skunks often
live in groups, multiple traps are necessary to trap them out
of an area. If you choose to do the trapping yourself, follow
the steps listed in Trapping Wildlife.
Removing
Skunks from Window Wells and Similar Areas |
| Occasionally,
striped skunks get stranded in window wells and similar areas.
If this occurs, slowly lower in a rough board that is long
enough to act as a ramp from the bottom to the top of the
window well. Because striped skunks cannot climb a steep slope,
the board should lean at no more than a 45 degree angle. You
may need to attach wood cleats or a heavy piece of cloth so
that the skunk can grip the board.
Crouch
when approaching the area to stay out of sight of the skunk.
If possible, have a second person on hand, with a vantage
point high enough to see the skunk, and to warn you if the
animal is becoming agitated.
Another
method is to tie the board to the end of a long pole and lower
it into the area. Once the board is placed, keep people and
pets away from the area until nightfall, when the skunk should
leave on its own. If the skunk doesn’t leave, it probably
can’t get out because the board is positioned at too
steep an angle.
Another
approach is to place smelly cheese or cat food in the back
of a small garbage can or a cat carrier. Slowly lower the
can or carrier sideways into the window well with the open
end facing the skunk. The skunk will smell the bait and go
inside. When it does, slowly raise the skunk and carrier,
elevator style, to ground level, keeping your hands on the
outside so you don’t risk being bitten. Leave the area
and the skunk will amble out—probably after it is done
eating.
Screen
the top of the well to prevent the problem from reoccurring.
Commercial well covers are available. |
Public Health
Concerns
The diseases
or parasites associated with skunk populations in Washington are
rarely a risk to humans.
Canine distemper,
a disease that affects domestic dogs, is found in skunk populations
(see "Public Health Concerns"
in Coyotes). Have your dogs vaccinated
for canine distemper to prevent them from contracting the disease.
Skunks may
also be infected with the bacterial disease tularemia (see "Public
Heath Concerns" in Beavers).
Never approach
a skunk that appears to be ill, is overly friendly, or approaches
you. If a person is bitten or scratched by a skunk, immediately
scrub the wound thoroughly with soap and water. Flush the wound
liberally with clean tap water. (In other parts of the United
States skunks can carry rabies.) Contact your physician and the
local health department immediately. If your pet is bitten, follow
the same cleansing procedure and contact your veterinarian to
ensure that your pet has proper protection.
Anyone handling
a skunk should wear rubber gloves, and wash their hands well when
finished.
Legal
Status
Because legal
status, trapping restrictions, and other information about skunks
change, contact your WDFW
Regional Office for updates.
Skunks are
not classified as game animals or furbearing animals (WAC
232-12-007). People can trap or shoot skunks on their own
property when the animals are causing damage to crops or domestic
animals (RCW
77.36.030). In such cases, no special trapping permit is necessary
for the use of live traps. However, a special trapping permit
is required for the use of all traps other than live traps (RCW
77.15.192, 77.15.194;
WAC
232-12-142).
It is unlawful
to release a skunk anywhere within the state, other than on the
property where it was legally trapped, without a permit to do
so (RCW
77.15.250; WAC
232-12-271).
Except for
bona fide public or private zoological parks, persons and entities
are prohibited from importing skunks into Washington State without
a permit from the U.S. Department of Agriculture and written permission
from the Washington Department of Health. Persons and entities
are also prohibited from acquiring, selling, bartering, exchanging,
giving, purchasing, or trapping a skunk for a pet or for export
(WAC
246-100-191).
