Pack Rat in Bend, OregonBushy-Tailed Woodrat. Stick Nest Builder. Vehicle Wiring Destroyer.

The pack rat — Neotoma cinerea, the bushy-tailed woodrat — is Central Oregon’s most misidentified and most underestimated rodent. Rural Bend, Tumalo, La Pine, Powell Butte, and Sunriver vacation property owners regularly discover massive stick nests under decks, in garages, and inside vehicles with no idea what built them. This is the complete identification and removal guide for pack rats in Bend and Deschutes County.

Found a Large Stick Nest Under Your Deck or in Your Garage? That Is a Pack Rat — Not a Bird.

Pack rats build the largest nests of any rodent species in Central Oregon — structures reaching 3 to 6 feet in diameter built from sticks, debris, insulation, and collected objects. If you are storing a vehicle in the same garage or carport, pack rats may already be inside the engine compartment chewing wiring harnesses, fuel lines, and brake lines. A single pack rat nest season in a Sunriver or La Pine vacation property garage commonly causes $500 to $5,000 in vehicle damage. Act before the next vacant period compounds the problem.

Direct Answer

What Is a Pack Rat and Why Is It Found Throughout Bend and Central Oregon?

The pack rat — formally called the bushy-tailed woodrat (Neotoma cinerea) — is a native Central Oregon rodent characterized by its large bushy squirrel-like tail, gray-brown and white bicolor fur, large eyes, large rounded ears, and instinctive behavior of collecting objects to incorporate into large stick nests. It is the dominant woodrat species throughout Deschutes County and the largest native rodent regularly encountered in Bend outbuildings, rural properties, and vacation homes.

Pack rats are not commensal rodents by nature — they do not seek to live inside human occupied structures the way house mice and Norway rats do. They are opportunistic builders who use human structures as convenient nest sites. Decks, garages, sheds, crawl spaces, and vehicles provide protected building locations pack rats exploit — particularly in rural Bend, Tumalo, La Pine, Powell Butte, and Sunriver vacation properties during vacant periods.

The pack rat in Bend, Oregon is the bushy-tailed woodrat (Neotoma cinerea), identified by its large bushy squirrel-like tail, gray-brown and white bicolor body, large prominent eyes, large rounded ears, and white feet. It reaches 12 to 17 inches total length. Pack rats build massive stick nests up to 6 feet in diameter under decks, in garages, and in crawl spaces. They cause serious vehicle wiring damage in stored vehicles and are most common in rural Bend, Tumalo, La Pine, Powell Butte, and Sunriver properties with juniper and Ponderosa pine habitat nearby.

Pack Rat Identification — What They Look Like in Bend

Pack rats are immediately distinguishable from Norway rats and roof rats by a single feature that requires no expertise to identify — the tail. Once you have seen a bushy-tailed woodrat tail, you will never confuse a pack rat with any other Central Oregon rodent.

Bushy-tailed woodrat Neotoma cinerea showing large bushy squirrel-like tail, gray-brown and white bicolor body, large prominent eyes and large rounded ears — common in rural Bend Oregon and Deschutes County — Bushy-tailed woodrat (Neotoma cinerea) — the pack rat of Central Oregon — showing the large bushy tail, bicolor body with white underside, and large eyes and ears that distinguish it from Norway rats and roof rats found in Bend urban and suburban areas.

Total Length

12 to 17 inches total including tail. Body 7 to 9 inches. Tail 5 to 8 inches. Similar total length to Norway rats and roof rats but with dramatically different tail type and softer overall appearance.

Weight

7 to 14 ounces. Variable based on season and food availability. Heaviest in fall before winter. Similar weight range to roof rats but with a notably different body build — broader and more rounded.

Tail — The Definitive ID Feature

Bushy, furry, squirrel-like. Covered in dense gray-brown fur throughout. Dramatically different from the hairless, scaly tails of Norway rats and roof rats. Once seen, this tail makes pack rat identification unmistakable at any distance. The common name bushy-tailed woodrat describes this feature perfectly.

Body Color

Gray-brown on back and sides — often with a yellowish or buffy tint in Central Oregon populations. Distinctly white on belly, chest, and undersides with a reasonably sharp color transition. White feet. Softer, more attractive appearance than commensal rat species.

Eyes

Large, prominent, dark brown. Larger relative to head size than commensal rats. The large eye is part of the overall softer appearance that causes many Bend property owners to misidentify pack rats as chipmunks or squirrels at first glance.

Ears

Large, rounded, prominent. Larger than Norway rat ears. Covered in fine fur. Large ears combined with large eyes give pack rats a wide-awake, alert facial expression distinctly different from the more compact facial features of house mice and commensal rats.

Feet

White on all four feet. Consistent feature across Central Oregon pack rat populations. White feet combined with white belly and gray-brown back create the overall bicolor appearance similar to deer mice but on a much larger animal.

Droppings

8 to 12mm long, dark, elongated with pointed ends. Smaller than Norway rat droppings (12 to 20mm) but larger than mouse droppings (3 to 6mm). Found in and around nest structures and in any area the pack rat regularly travels. Often intermixed with collected debris near nest entrances.

The Single Most Important Pack Rat ID Fact

If the tail is bushy and furry like a small squirrel tail, it is a pack rat — not a Norway rat or roof rat. Norway rats and roof rats both have completely hairless, scaly tails. This single feature requires zero expertise to identify and is visible from a distance. Every other identification feature is secondary to the tail. In Bend and Deschutes County, any large rodent with a bushy tail is a bushy-tailed woodrat (Neotoma cinerea) — the region’s native pack rat species.

Where Pack Rats Are Most Active in Bend and Central Oregon

Pack rat pressure is heavily concentrated in rural and semi-rural areas of Deschutes County with juniper woodland, Ponderosa pine, and high desert sagebrush habitat adjacent to structures. Urban Bend sees pack rats occasionally — rural Bend, Tumalo, Powell Butte, La Pine, and Sunriver see them consistently.

Tumalo — Highest Pack Rat Density Near Bend

Tumalo and surrounding high desert properties between Bend and Redmond face intensive pack rat pressure. Juniper woodland habitat directly adjacent to rural properties provides ideal pack rat territory. Properties with outbuildings, woodpiles, and vehicle storage face year-round pack rat activity.

Critical Pressure Zone

Powell Butte — Rural Pack Rat Territory

Powell Butte’s rural high desert character supports dense pack rat populations. Agricultural properties, outbuildings, and equipment storage areas face significant pack rat nest establishment. Machinery and equipment left stationary for weeks becomes a pack rat nest site.

Critical — Rural Properties

La Pine — Pack Rat and Vacation Property Intersection

La Pine’s combination of rural character and vacation property density creates the highest-consequence pack rat situation in the service area. Vacation properties left vacant for weeks or months allow pack rat nest establishment in garages and under decks without detection.

Critical — Vacation Properties

Sunriver — Vacation Home Pack Rat Risk

Sunriver vacation properties bordering high desert and forest habitat face seasonal pack rat pressure during vacancy periods. Garages with stored vehicles are the primary risk. Pack rats established in a garage during a two-week vacancy can cause significant vehicle damage before the owner returns.

Critical — Vehicle Damage Risk

Rural Bend Outskirts — NE and SE Bend

Properties on Bend’s rural outskirts bordering undeveloped high desert face pack rat pressure from adjacent native habitat. Larger lot properties with outbuildings, woodpiles, and equipment storage see more pack rat activity than urban Bend neighborhoods.

High — Rural Interface

Terrebonne and Sisters Rural Areas

High desert and juniper woodland throughout Jefferson and northern Deschutes County support pack rat populations that affect rural residential and agricultural properties. Outbuildings and equipment storage face the same risk patterns as Tumalo and Powell Butte.

Pack Rat Stick Nests — What They Are and Why They Grow So Large

The pack rat stick nest — technically called a midden — is the most distinctive evidence of pack rat activity and the most surprising feature for Bend property owners who encounter one for the first time. Understanding nest biology explains why they grow so large and why simple removal without exclusion sealing fails.

What a Pack Rat Nest Contains

A Central Oregon pack rat midden contains sticks from 6 inches to 3 feet long, chunks of cactus and juniper, pine cones, bark strips, pieces of insulation, wire, collected human objects including keys, coins, tools, and any portable item the pack rat discovered — all bound together with urine-soaked debris that hardens into a compact mass over time.

How Large Nests Get

A first-season pack rat nest under a Bend or La Pine deck reaches 12 to 24 inches in diameter. After two seasons the same nest commonly reaches 2 to 3 feet. Established middens left undisturbed across multiple pack rat generations reach 3 to 6 feet in diameter and 2 to 4 feet in height — filling entire under-deck spaces and blocking garage corners completely.

Why Nests Are Reused Across Generations

Pack rats return to established midden sites generation after generation. A nest site used by one pack rat broadcasts chemical signals that attract successor pack rats to the same location. Removing the nest without sealing the access point results in a new pack rat discovering the vacated site and beginning construction within weeks — in the same location.

The Urine Concentration Problem

Pack rats urinate extensively throughout and around their nest structure. Over seasons and years, urine accumulates in the nest mass and surrounding area creating highly concentrated pathogen load. Large established nests should be wet-treated with enzyme solution before any physical disturbance. Never dry-disturb an established pack rat midden without respiratory protection.

Collecting Behavior and Object Return

Objects collected by pack rats — including keys, coins, and tools — are incorporated into the nest structure and do not follow the pack rat if it moves. Objects found in pack rat nests are removed during nest remediation. Do not expect collected objects to be at the edge of the nest — they are embedded throughout the midden structure and only found during complete nest removal.

Common Nest Locations on Bend Properties

Under decks and porches with accessible undersides. In detached garage corners and behind stored equipment. Inside engine compartments of parked vehicles. In crawl spaces of rural properties. Inside outbuilding walls. Against woodpiles stored adjacent to structures. Any protected void space within reach of a pack rat territory.

Pack rat middens on rural Deschutes County properties have been documented in paleontological research as being thousands of years old in some desert canyon locations — the urine-hardened debris preserves plant material for extraordinary periods. Modern residential pack rat nests are not ancient but can represent 5 to 10 years of layered construction when properties change hands and new owners inherit established midden sites.

Pack Rat Vehicle Damage in Bend Garages — The Underreported Problem

Vehicle wiring damage from pack rats is the most financially significant pack rat problem in Bend, Sunriver, and rural Deschutes County — and the most commonly discovered after it is too late to prevent.

Pack rats access vehicle engine compartments through wheel wells. Once inside, the engine compartment provides warmth, shelter, and material for nest building. Pack rats chew through engine wiring harnesses, brake lines, fuel lines, and air filter material within days of gaining access to a parked vehicle. Vehicles stored in vacation property garages during owner absence are the primary victim — damage is discovered when the owner returns and the vehicle will not start or throws multiple fault codes.

Engine Wiring Harness

Main wiring harness connecting engine sensors, fuel injection, and ignition systems. Pack rats chew through insulation and wire bundles causing multiple simultaneous electrical faults. Modern vehicles may require dealer-level diagnosis to identify all damage.

Repair: $500–$5,000

Brake and Fuel Lines

Flexible brake line sections and rubber fuel lines in engine compartments are chewed through by pack rats. Brake line failure creates a safety emergency. Fuel line damage creates fire risk. Both create situations where the vehicle cannot be safely operated.

Repair: $300–$1,500

Air Filter Housing and Intake

Pack rats nest inside air filter housings and intake systems. Nesting material in the air intake system can be drawn into the engine causing damage. Air filter replacement and intake system cleaning required after pack rat nesting confirmed.

Repair: $150–$600

Engine Insulation and Sound Deadening

Engine hood insulation and sound deadening material is shredded for nesting. Less operationally critical than wiring damage but contributes to increased engine noise and heat management issues over time.

Repair: $200–$800

HVAC Cabin Air System

Pack rats occasionally access cabin air filter housings from inside the engine compartment, nesting in the HVAC air intake path. Nesting material drawn into the cabin air system affects air quality inside the vehicle and can damage blower motors.

Repair: $200–$700

Catalytic Converter Heat Shields

Pack rats cache nesting material against catalytic converter heat shields which operate at high temperatures. Nesting material stored against hot exhaust system components creates fire risk when the vehicle is started after extended storage.

Fire Risk — Immediate Inspection

Protect Stored Vehicles in Sunriver and La Pine Garages

Any vehicle stored in a Sunriver, La Pine, Tumalo, or rural Bend garage for more than two weeks during pack rat active season — April through November — faces pack rat engine compartment access risk. Before starting a stored vehicle after any absence, check under the hood for nesting material before operating. Starting a vehicle with nesting material against exhaust components creates fire risk. Rodent wire tape wrapping on vulnerable wiring harnesses and electronic deterrent devices inside engine compartments are documented prevention options for stored vehicles. Exclusion sealing of the garage itself is the most reliable protection. See our vacation property rodent control service →

Signs of Pack Rat Activity in Your Bend Property

Pack rat evidence is larger and more visible than mouse evidence. The stick nest itself is usually the most dramatic sign — but earlier detection before full nest establishment prevents vehicle damage and structural issues.

Stick and Debris Pile Under Deck or in Garage

Any accumulation of sticks, debris, plant material, and collected objects in a sheltered location is a pack rat midden in progress or already established. Small beginning nests are often dismissed as wind-blown debris until they reach obvious size.

Missing or Displaced Objects Near the Structure

Keys, coins, tools, shiny objects, and small items that disappear from decks, garages, or outbuildings and are found incorporated into a stick pile elsewhere are definitive pack rat collecting evidence. The specific object displacement pattern is unique to pack rats among Central Oregon rodents.

Droppings in and Around Nest Area

8 to 12mm elongated dark droppings concentrated in and immediately around the nest area and along regular pack rat travel routes. Less widely distributed than house mouse or Norway rat droppings — pack rats are more territorial and have more concentrated activity areas.

Strong Musky Urine Odor

Pack rat urine has a strong, distinctive musky odor more pungent than house mouse urine. Detectable near established nest sites and in enclosed spaces where pack rat activity is concentrated. The odor intensifies in warm weather as urine in the nest material volatilizes.

Nocturnal Activity Sounds

Dragging, scraping, and movement sounds from under decks and in garages at night as pack rats collect and transport nest material. Heavier than mouse sounds — pack rats transporting large sticks create audible dragging sounds. Activity peaks between dusk and 2 AM.

Chewed Wiring or Hoses on Vehicles

Fault codes, warning lights, or starting issues in a stored vehicle may indicate pack rat wiring damage. Physical inspection under the hood reveals chewed wire insulation, severed harness sections, or nesting material inside air filter housing. Never ignore sudden electrical issues in a stored vehicle without checking for rodent damage.

Gnaw Marks on Structural Wood

Large rough gnaw marks on deck structural members, garage door frames, outbuilding siding, and stored lumber. Pack rats gnaw on wood both for nest material collection and incisors maintenance. Gnaw patterns on deck joists and posts indicate pack rat territory use of the structure.

Live Sightings at Dusk or Dawn

Pack rats are primarily nocturnal but occasionally observed at dawn and dusk. The bushy tail is immediately visible and distinctive. Pack rats move with a more deliberate, less frantic movement pattern than house mice — they stop and examine their surroundings regularly rather than scurrying continuously.

Pack Rat Damage Beyond Vehicle Wiring in Bend Properties

Vehicle wiring damage is the most dramatic pack rat problem but not the only one. Established pack rat nest sites create multiple damage categories across Bend and rural Deschutes County properties.

Structural Wood Gnawing

Pack rats gnaw deck joists, posts, blocking, and structural framing of outbuildings for nest material and incisor maintenance. Concentrated gnawing at specific structural connections weakens members over time in multi-season infestations.

Structural Repair: $400–$3,000

Insulation Removal and Contamination

Pack rats pull insulation from crawl space floor joists and wall cavities for nest material. Contaminated insulation removed requires professional replacement with decontamination protocol. Floor joist insulation loss increases heating costs in La Pine and rural Bend properties.

Restoration: $600–$2,500

Stored Item Contamination

Items stored in garages and outbuildings adjacent to pack rat nest sites are contaminated with urine and droppings and shredded for nest material. Camping gear, outdoor equipment, and stored clothing are common targets in Sunriver and La Pine vacation property garages.

Loss: Variable

Water Line Damage in Crawl Spaces

Pack rats accessing crawl spaces chew PEX and rubber water lines as observed with other rat species. In rural Bend and La Pine vacation properties with crawl space water supply lines, pack rat plumbing damage discovered after extended vacancy can cause significant water damage.

Plumber Repair: $300–$2,000

Deck and Porch Structural Assessment

Large established pack rat middens under decks retain moisture that accelerates wood rot in adjacent structural members. Deck joists and posts with chronic pack rat nesting require structural assessment for moisture-related deterioration beyond gnaw damage.

Assessment and Repair: $300–$2,500

Propane and Generator Equipment

Rural Bend and La Pine properties with propane systems and backup generators face pack rat nesting in equipment housings. Pack rats chew propane regulator lines and generator wiring. Equipment inspection after pack rat removal is required before operating any fuel-burning equipment.

Equipment Service: $200–$1,500

Professional Pack Rat Removal and Nest Remediation — Bend and Deschutes County

Pack rat removal has a specific protocol that differs from commensal rat removal. The nest structure itself requires safe removal and the access point requires permanent sealing — both steps are essential to prevent immediate recolonization.

Species Confirmation and Nest Assessment Pack rat confirmed from tail type, nest structure, and collecting behavior evidence. Nest size assessed — diameter, height, and estimated age from construction material stratification. All potential entry points to the nest site documented. Vehicle inspection for engine compartment nesting if garage is involved. Written assessment delivered with photos.
Large-Format Snap Trap Placement Rat-sized snap traps placed at confirmed pack rat travel routes and nest entrances. Pack rats are neophobic — traps are placed without disturbance to the nest or surrounding area and left in place minimum 5 to 7 days before being considered effective. No poison — dead poisoned pack rats decomposing in nest structures create severe odor problems within the large, enclosed midden mass.
Confirmed Removal Before Nest Disturbance Zero new activity for minimum 5 consecutive days confirmed before any nest disturbance begins. Disturbing an active pack rat nest without confirmed removal drives the pack rat to relocate — often to a new structural void on the same property — rather than eliminating the problem.
Safe Nest Wet-Treatment Before Removal Entire nest structure wetted thoroughly with enzyme decontamination solution before any physical disturbance. N95 or better respiratory protection, nitrile gloves, and protective clothing required. Wetting the nest prevents dried urine and debris from becoming airborne during removal — the primary exposure pathway for leptospirosis during pack rat nest cleanup.
Complete Nest Material Removal and Disposal All nest material removed in sealed bags — sticks, debris, collected objects, contaminated insulation, and all accumulated material. Complete removal required — leaving any nest material in place provides framework for a successor pack rat to rebuild rapidly. Collected objects sorted and returned to owner. Structural surfaces beneath nest exposed for decontamination.
Surface Decontamination of Nest Site Enzyme decontamination applied to all surfaces exposed after nest removal — structural wood, concrete, soil surface. Urine soaking in structural wood surfaces requires thorough enzyme treatment to neutralize both pathogen load and the chemical signals that attract successor pack rats to the established midden site. This step is essential for preventing immediate recolonization.
Permanent Exclusion Sealing of Access Points Every structural gap through which the pack rat accessed the nest site sealed with 304-grade stainless steel hardware cloth mechanically fastened to framing. Under-deck perimeter enclosed with hardware cloth buried 6 inches below grade to prevent tunneling access. Garage door seal gaps addressed. Vehicle protection recommendations provided. See our exclusion service → and full process overview →

Pack Rat Prevention for Bend and Rural Deschutes County Properties

Prevention is always more effective and less expensive than nest remediation. These specific measures address the conditions that attract pack rats to Bend and rural Deschutes County structures.

Remove Woodpiles From Building Contact

Woodpiles stacked against structures are pack rat nest starter kits. Move all woodpile storage minimum 20 feet from any building. Stack wood on elevated racks rather than ground contact. This single change eliminates the most common pack rat nest initiation site on rural Bend properties.

Enclose Under-Deck Perimeters

Install stainless steel hardware cloth around the full perimeter of deck undersides, buried 6 inches below grade to prevent tunneling access. Open deck undersides are the most common pack rat nest establishment site in Sunriver and La Pine vacation properties. This is the single most effective pack rat prevention investment for vacation properties.

Seal Garage Entry Points

All gaps in garage walls, around overhead door frames, and at garage door bottom seals sealed with stainless steel mesh or replacement weatherstrip. Pack rats enter most garages through surprisingly small gaps — any gap larger than one inch is accessible. Priority sealing for any garage storing vehicles during vacancy periods.

Trim Dense Vegetation Away From Structures

Dense juniper, sagebrush, and ornamental shrubs growing against building foundations provide pack rat travel cover and nest initiation sites. Maintain minimum 3-foot cleared zone between dense vegetation and any structure. This reduces pack rat territorial use of the building perimeter.

Vehicle Protection During Vacancy Periods

For vacation properties with stored vehicles, parking on hardware cloth mats under the vehicle (pack rats avoid climbing over mesh), using commercial rodent deterrent tape on wiring harnesses, placing sound-emitting deterrent devices near parked vehicles, and regular startup and movement of stored vehicles reduces — but does not eliminate — pack rat vehicle access risk.

Annual Pre-Season Inspection

Annual property inspection before summer rental season — May is optimal for Sunriver and La Pine properties — identifies early-stage nest construction before it reaches size that causes vehicle damage or structural issues. Small nests addressed early cost dramatically less to remove than large established middens discovered after extended vacancy.

Pack Rat Questions — Bend and Deschutes County Property Owners Ask

What does a pack rat look like in Bend, Oregon?

A pack rat in Bend is the bushy-tailed woodrat (Neotoma cinerea) — 12 to 17 inches total length with a large bushy squirrel-like tail, gray-brown and white bicolor body, large prominent dark eyes, large rounded ears, and white feet. The bushy tail is the single definitive identification feature — no other Central Oregon rat species has a furry tail. Norway rats and roof rats both have completely hairless, scaly tails.

What is the difference between a pack rat and a Norway rat in Bend?

Pack rats have a distinctly bushy, furry squirrel-like tail — Norway rats have a thick hairless scaly tail shorter than body length. Pack rats are bicolor gray-brown and white with white feet — Norway rats are uniformly brown with gray feet. Pack rats build large visible stick nests above ground — Norway rats burrow underground. Pack rats are native wildlife most common in rural areas — Norway rats are commensal rodents concentrated near the Deschutes River corridor and Downtown Bend commercial areas. Full Norway rat guide →

Why do pack rats collect objects in Bend properties?

Pack rats are instinctive collectors — a documented behavior consistent across all woodrat species in North America. They collect shiny, interesting, or structurally useful objects and incorporate them into nest structures. In Bend and Deschutes County properties, collected items include keys, coins, wire, insulation pieces, pine cones, and virtually any portable object found near the nest site. Objects are not retrieved after removal from the nest.

How large do pack rat nests get in Central Oregon properties?

First-season pack rat nests reach 12 to 24 inches in diameter. After two seasons the same nest reaches 2 to 3 feet. Established middens undisturbed across multiple generations reach 3 to 6 feet in diameter and 2 to 4 feet in height. In Sunriver and La Pine vacation properties left vacant for extended periods, pack rat nests in garages can reach substantial size — filling entire corners and blocking vehicle access.

Do pack rats damage vehicles in Bend garages?

Yes. Pack rats cause significant vehicle damage in Bend, Sunriver, and rural Deschutes County garages. They chew engine wiring harnesses, brake lines, fuel lines, and air filter material in vehicles stored in garages during vacancy periods. Vehicle wiring repair from pack rat damage commonly costs $500 to $5,000. Before starting any stored vehicle after a vacancy period, check under the hood for nesting material — particularly against heat-generating exhaust components. Vacation property protection service →

Are pack rats dangerous to humans in Central Oregon?

Pack rats in Central Oregon do not carry hantavirus — that is specific to deer mice. However, pack rat urine and nesting material carry leptospirosis and other pathogens. Large established nests contain concentrated accumulated urine that creates pathogen exposure during disturbance. Always wet pack rat nests with enzyme solution before disturbance and handle with nitrile gloves and N95 respiratory protection. Pack rats are not aggressive toward humans and do not bite unless cornered. Hantavirus guide for Central Oregon →

How do you remove a pack rat nest in Bend?

Professional pack rat nest removal requires first confirming the pack rat is removed through trapping, then wetting the entire nest with enzyme decontamination solution before disturbance, removing all nest material in sealed bags using gloves and respiratory protection, decontaminating all surfaces beneath the nest, and sealing every structural access point with stainless steel hardware cloth to prevent a successor pack rat from recolonizing the established midden site. Removal without exclusion sealing is guaranteed to fail.

What attracts pack rats to Bend properties?

Pack rats are attracted to properties with protected structural voids for nest building, adjacent materials for nest construction, and food sources. Specific attractants include woodpiles against structures, open deck undersides, detached garages with gaps, dense juniper or sagebrush vegetation near buildings, and any structural void providing protected building space. Removing woodpiles from building contact and enclosing deck undersides are the two highest-impact prevention measures for rural Bend and Deschutes County properties.
