Animal Pest Management Around Homes in Nevada

Animal Pest Management Around Homes

Nevada
Non-poisonous snakes are harmless
and should be left alone. They are
beneficial to the environment.
Many Snakes Control Pests
Gardeners want to control diseases, insects and get rid of persistent weeds. Pesticides are often
recommended. However, their over use or misuse may be harmful to the user, the user’s neighbors
and the environment including beneficial organisms–honey bees, fish, endangered species and insect
predators. It is best to adopt an Integrated Pest Management (IPM) strategy that uses a combination
of cultural, mechanical, physical and chemical techniques to manage pests. Integrated Vertebrate Pest
Management (IVPM) is similar to IPM. Vertebrate pests occupy an area because the habitat meets
their needs for shelter, protection from predators, food and water. Much of what is done as IVPM
modifies these needs and excludes the pest from the property or buildings. Vertebrate pests are trapped
to be relocated or killed. Habitat modifications and trapping may or may not be difficult. Predators
may be used in some cases to reduce pest numbers; however, this rarely eliminates the pest. Repellents
are available, but most are ineffective.
Use integrated methods to control vertebrate pests, see the following table. Contact your local
Cooperative Extension or Nevada Department of Agriculture offices for additional information if a
pest persists after these techniques have been tried. The back cover lists phone numbers and addresses.
Control of some vertebrate pests (lions, bears, dogs, cats, etc.) is best left to a professional. Contact
Animal Control in your county, USDA Wildlife Services or Nevada Division of Wildlife for assistance.
Bats play an important ecological role
by eating flying insects–including mosquitoes.
Encourage their presence; build a bat house in
your yard. Bats do best near ponds and
streams. Rabies from bat bites occurs only
rarely.
Bats are not pests!

Control
Cultural Control
Plant deer resistant plants or “lure” crops;
harvest large blocks of timber 100-200 acres,
to provide forage away from home and crops
House/Deer Mice Sanitize counters; put food in rodent proof
Rats/Norway Rats containers; reduce food, water, and shelter;
control weeds and remove debris from around
buildings
Biological Control
Mountain lions and wolves; do not kill (check the
law before doing anything to wild animals)
Cats–limited effectiveness
Bears
Reduce cover around buildings; thin woods
and forests near structures; never leave food or
garbage available for bears, this attracts them
Ask Nevada Division of Wildlife biologists to
trap and relocate
Raccoons
Same as for bears; reduce food around
buildings
Dogs–limited effectiveness
Moles
Reduce soil moisture or compact soil to deter
digging; reduce population of soil insects,
nightcrawlers and earthworms; use milky spore
or pesticides to kill grubs
Dogs, cats–limited effectiveness
Pocket Gophers
Flood irrigation
Dogs, cats–limited effectiveness
Voles
Reduce cover by tilling, mowing or thinning
vegetation and remove excess mulch to expose
to predators
Dogs, cats, raptors may help reduce the
population
Ground Squirrels
Remove cover, trash, etc. around buildings;
seal repeated burrow; retreat new burrows;
deep tillage burrows (repeat as needed);
remove vegetation and wood piles
Dogs, cats, hawks, eagles, other raptors, rattle
snakes, gopher snakes, and coyotes

Erect wire/electrical deer fencing; fence off gardens, farm fields,
orchards and nurseries
Repellents: sulfurous are best, they work up to 4 weeks, hot/
spicy ones work okay; propane guns frighten animals for 2-4
weeks then they get use to them
Mouse/rat traps and glue boards; concrete, mortar, galvanized
sheeting, heavy gauge hardwire cloth or caulk to close off entry
holes larger then ½ inch for rats and ¼ inch for mice
Anticoagulant or other toxic bait
Bear-proof trash containers; fencing; notify Nevada Division of
Wildlife (trap and relocate); DON’T FEED BEARS!
None
Raccoon-proof trash containers with secure lids; electric fencing;
exclude from chimneys, crawl spaces, etc.; traps, USDA Wildlife
Services may provide traps
None
Mole traps; flooding; exclude from small areas with wire baskets
for bulbs, etc.
Use soil insecticides to reduce food supply (moles don’t eat
plants)
Gopher traps; place trap in burrow; wire cylinders to protect plants
Baits with strychnine; zinc; aluminum phosphide; and anticoagulants or use gas cartridges and fumigants; apply toxic baits
by hand or with mechanical applicator
Wire mesh cylinders around plants; snap traps - about a dozen for a
small area
Zinc phosphide (restricted use pesticide, contact Nevada
Department of Agriculture); anticoagulant baits; gas cartridge
“smoke bombs,” and sulfurous or capsaicin compounds
painted on trunks may prevent damage (not tested on voles)
Exclude from buildings using ¼ inch mesh hardwire cloth, caulking; sheet metal cylinders around trunks of trees and bird feeders;
shooting okay; trap and relocate or euthanize; kill trap
Zinc phosphide (restricted use pesticide, contact Nevada
Department of Agriculture); anticoagulant baits; fumigants; gas
cartridge

Dogs, cats, raptors
Douglas/Western
Grey Squirrels
Plant trees away from buildings; remove
branches near buildings to reduce access to
roof
Dogs, cats, raptors
Wood Rats
Close openings larger than ½”
Wild predators and raptors
Feral Cats
Seal buildings; don’t leave dog/cat food out
Large dogs, wild predators
Woodpeckers
Sapsuckers

nesting box (6” X 6” X 22–26”) with a thick
layer of sawdust in the box. Let them use it
and then trap them in it
None
Pigeons
Plant more large growing trees (pigeons like
open areas); eliminate roosting spots

encourage falcons to nest; cats with access to
nests and roosts

Integrated Pest Management
Effective in the home garden and landscape. It takes time and effort to develop your own program, but in the
long term it will mean healthier plants, safer pest control for you and your animals, and a better environment.
