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,
nightlight's, 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.
