Wildlife Control at Home
Control Wildlife Damage Around the Home
With Common Sense Control Methods
Whether you
are a home gardener, enjoy landscaping
around your home or just own your own
home, there are times when certain
species of wildlife can become a
nuisance or a pest and cause
damage to plants and even economic
losses. Wildlife damage problems can
occur throughout the year, but the fall
and winter months are times when food
supplies and cover may become more
limited for many wildlife species,
causing them to find your home or
landscape an attractive place to call
home. Solving wildlife damage problems
may seem out of your control - but most
often, you have more control over the
problem than you think. It might not be
easy - but if you think through the
problem and put forth some effort - you
can often cut your losses and maybe even
eliminate them.
Many
different species of wildlife can become
a nuisance and cause problems under
certain conditions. Raccoons, skunks,
snakes, woodchucks and other rodents
such as moles, house mice, and tree
squirrels can often cause problems. In
addition, whitetail deer populations
have increased to the point in many
urban environments where they are
becoming a nuisance by browsing on
landscape plantings. Other problem
wildlife can include starlings, pigeons,
sparrows, or the nuisance woodpecker
damaging the wood siding on your home,
just to name a few.
Think Through the Problem
People
experiencing a problem caused by
critters usually want an easy, quick
solution and often ask "Is there
something I can spray to get rid of this
pest?" It is never quite that easy.
Preventing and controlling wildlife
damage requires a thought process and
often includes using integrated pest
management techniques. A successful
wildlife damage program often makes use
of a combination of control options and
usually begins with an accurate
assessment of the damage and
identification of the desired outcome.
Wildlife damage management is the
opposite of managing property to attract
wildlife. To manage for wildlife, you
must make sure that animals have
sufficient food, water, and cover
throughout the year. If you have
unwanted animals around your home, it is
a sure bet that there is food, water and
cover in the area. The solution is to
remove at least one of these elements -
and if you can remove two, it’s even
better.
Try this
sequence in thinking through a wildlife
damage problem:
-
Identify the wildlife species
causing the problem. This is the
most important step. Correctly
identifying the species of wildlife
causing damage may seem simple, but
it can be challenging under certain
circumstances. Learn about the life
history and habitat requirements for
the wildlife species that may be a
potential problem in your area.
- Are
there cultural techniques which you
could use to modify the habitat and
reduce the chances of having a wild
life damage problem? For instance,
there may be certain plants which
could be used in your home landscape
that might not be an attractive food
source for deer. Would more frequent
mowing or herbicide use reduce the
amount of weedy cover needed for a
build up of rodent populations?
- Is
there some way you can keep the
animal causing damage from getting
into the site?
- If
you can’t build them out, can you
repel them from the area? Sometimes
you can use chemical, home-made,
visual or sound repellents to solve
and control a problem.
- If
you can’t put up an effective
barrier or repel the animals from
the problem site, the last step may
involve removing from the area the
animals that are causing the damage.
It may be necessary to trap, shoot,
use gas cartridges in dens, or use
poison baits to control a wildlife
damage problem. Of course, when
considering these alternatives for
controlling most wildlife species
you should check with a Conservation
Agent or local animal damage control
agent to get approval. Often these
persons will also provide some
assistance.
-
Remember that no entire species of
wild animal is a nuisance or pest
all the time. The trick is to deal
only with the animal(s) causing
damage, not try to eradicate the
entire population.
- A
final consideration: Is it worth the
effort? It takes quite a bit of time
and money to solve and control a
wildlife damage problem. Can you
tolerate some damage or losses
caused by wildlife? Remember the
aesthetic benefits derived from
viewing wildlife and the importance
of managing habitats for those
wildlife species you wish to attract
to your property. Ask yourself if
the economic loss is greater than
the control cost. If it is, then it
is worthwhile to develop and
implement a wildlife damage control
program.
Living With Wildlife
Wild animals
contribute to our enjoyment of nature
and outdoor recreation, but they can
also damage property, agriculture, and
natural resources and threaten human
health and safety. Equipped with the
right information and tools, most
homeowners can solve their own problems
and learn to live with wildlife. For
example, trimming trees and shrubbery
are ways of changing a habitat to make
it less attractive to unwanted flocks of
birds or even snakes.
The
following information may assist in
keeping that curious raccoon out of the
garbage can, that persistent rabbit or
deer out of the garden, that goose or
duck out of the backyard pool, that
woodpecker off the siding, and that
swooping bat out of the attic. Caution
should always be taken to avoid overly
aggressive animals.
Squirrels and Other Rodents
To keep
these animals from becoming a permanent
part of the family home and yard,
screens, vents, and fan openings; keep
doors and windows in good repair;
tighten eaves; replace rotten boards;
cap the chimney; trim overhanging trees;
remove bird feeders or use
squirrel-proof feeders; and remove
acorns and other nuts from the yard.
Chipmunks can be deterred by removing
denning habitat, which includes logs,
rock walls, and stones.
Woodchucks
These
animals, also known as groundhogs,
sometimes burrow near buildings, browse
in gardens, and damage fruit trees and
ornamental shrubs. Fencing can help
reduce woodchuck damage. The lower edge
of the fence should be buried at least
10 inches in the ground to prevent
burrowing. The fence should be 3 to 4
feet high, with a surrounding electric
hot-shot wire placed 4 to 5 inches off
the ground.
Opossums and Skunks
Opossums and
skunks become a problem to homeowners by
raiding garbage cans and bird feeders;
eating pet foods; and living under
porches, low decks, open sheds, and any
other areas that provide shelter. Skunks
also dig holes in lawns, golf courses,
and gardens. Both animals sometimes kill
poultry and eat eggs. To keep opossums
and skunks from denning under buildings,
seal off all foundation openings with
wire mesh, sheet metal, or concrete.
Chicken coops can be protected by
sealing all ground-level openings into
the buildings and by closing the doors
at night. Foraging in garbage cans may
be eliminated by providing
tight?-fitting lids and straps.
Bats
Bats prefer
to avoid human contact; however, they
are known to establish roosts in attics
and abandoned buildings. Building and
attic roosts can be eliminated by
sealing entry and exit holes (after the
bats have left) with such materials as
1/4-inch hardware cloth, caulking, or
wire mesh. If a bat makes its way into
the house, you can usually encourage it
to leave after dark by turning on lights
and opening windows and doors.
Rabbits
Rabbits can
be kept out of the garden or away from
ornamental plants and small trees by
using products containing repellents
such as Hinder or by placing a 2-foot
poultry fence around the area. It is
important to bury the fence at least 6
inches beneath the surface of the
ground. For information about taste
repellents, check your local garden or
farm center. Before using any chemical
repellents, read the label carefully and
check with your State pesticide
regulatory agency for application
guidelines.
Raccoons
Raccoons are
attracted to easy food sources, like
garden produce, garbage, and pet food.
To help prevent scavenging, use metal
trash cans that are fastened to a pole
or to another solid object. A strap or
latch that secures the lid of the
garbage can is also helpful. To keep
raccoons out of the garden, use two
strands of electric livestock fence. The
strands should be placed 4 and 8 inches
respectively off the ground and surround
the entire garden. Exercise caution when
implementing this exclusionary method in
urban areas.
Raccoons
will also readily inhabit attics,
chimneys, and sheds. Use metal flashing
and 1-inch-mesh hardware cloth to block
entrances.
Snakes
The best way
to keep snakes out of your house and
yard is to seal cracks and openings
around doors, windows, water pipes,
attics, and foundations. Removing logs,
woodpiles, and high grass and
controlling insects and rodents are also
helpful. Remove nonpoisonous snakes from
inside buildings by placing piles of
damp burlap bags in areas where snakes
have been seen. After the snakes have
curled up beneath the bags, remove the
bags and snakes from the building. To
remove dangerous snakes, call a
professional pest control company.
Woodpeckers
These birds
damage buildings by drilling holes into
wooden siding, eaves, or trim boards,
especially those made of cedar or
redwood. If the pecking creates a
suitable cavity, the bird may use it for
nesting. Effective methods of excluding
woodpeckers include placing lightweight
mesh nylon or plastic netting on the
wooden siding beneath the eaves,
covering pecked areas with metal
sheathing, and using visual repellents
like "eye-spot" balloons.
Deer
Deer feed on
row crops, vegetables, fruit trees,
nursery stock, stacked hay, and
ornamental plants and trees. Deer can be
discouraged by removing supplemental
food sources and by using scare devices
and repellents. The only sure way to
eliminate deer damage is to fence the
deer out. A wire-mesh fence is effective
if it is solidly constructed and at
least 8 feet high. Electric fencing also
helps reduce damage.
Coyotes and Foxes
These
animals may carry rabies and sometimes
prey on domestic pets, rabbits, ducks,
geese, chickens, young pigs, and lambs.
Coyotes also kill calves, goats, and
deer. Net-wire and electric fencing will
help exclude foxes and coyotes; however,
because they are good climbers, a roof
of net wire on livestock pens may also
be necessary. For more information about
fencing, contact your local county
extension office.
The
protection of livestock and poultry is
most important during the spring denning
period. Foxes and coyotes will often den
close to farm buildings, under
haystacks, or inside hog lots or small
pastures used for lambing. Shed lambing
and farrowing in protected enclosures
can be useful in preventing predation on
young livestock. Additionally, noise-
and light-making devices, such as the
Electronic Guard, may keep these
predators away. Guarding dogs are also
useful in preventing predation on sheep.
Regrettably, dispersal methods are not
effective in all situations, so other
methods, including trapping or snaring,
may have to be used.
Mountain Lions and Bears
As bear and
lion habitats continue to decrease,
interactions between these animals and
humans continue to increase. Bears are
noted for destroying cornfields and
trees, scavenging in garbage cans,
demolishing the interiors of cabins and
campers, and killing livestock. Lions
are serious predators of sheep, goats,
domestic pets, large livestock, poultry,
bighorn sheep, and deer. Typical bear
and lion predation on sheep leaves 10 or
more killed in a single attack, and both
species are known to attack humans.
Prevention
is the best method of controlling bear
and lion damage. Heavy woven and
electric fencing can effectively deter
bears and lions from attacking livestock
and damaging property. Loud music,
barking dogs, exploder cannons,
fireworks, gunfire, nightlights,
scarecrows, and changes in the position
of objects in the depredation area often
provide temporary relief. The best way
to protect pets is to keep them inside
an enclosed kennel or shelter. Using
guarding dogs, removing garbage and dead
carcasses, and placing crops and
beehives at considerable distances away
from timber and brush may reduce damage
by bears. Mountain lions also prefer to
hunt where escape cover is close by;
removal of brush and trees within a
quarter of a mile of buildings and
livestock may reduce lion predation.
Professional
relocation of damaging mountain lions
and bears is sometimes necessary. For
more information about State laws and
regulations concerning relocation or
lethal control of mountain lions and
bears, contact your State wildlife
agency.
Remember,
think through your problem before
attempting to invest in a control
program. What is the easiest, cheapest,
most practical way to control the
problem? What will be the least
hazardous to pets, people, and
non-target wildlife? Are you losing
enough money to justify a control
expense? Your goal should be to reduce
damage to a level you can live with.
