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.
