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.
