🐀 Rat Removal in Chatham County

Rat Removal in Chatham County, Georgia

If you've been searching 'rats in my walls' or 'scratching in walls at night' anywhere in Savannah, Pooler, Tybee Island, or the rest of Chatham County, you almost certainly have a rat problem — and it's almost certainly worse than you think. Coastal Chatham has two rat species working at the same time: roof rats (Rattus rattus) dominate the Savannah Historic District, Ardsley Park, and the older intown housing because of the mature live oak canopy and the tourism-corridor food density, while Norway rats (Rattus norvegicus) push out of storm sewers and the older inner-city industrial corridors into basements and crawl spaces. Mixed-species infestations are routine in older Chatham housing. This page covers what rats in your walls sound like, how to tell which species you have, where they're getting in, the damage and disease risks that make this urgent, what rat removal costs in the Savannah area, and how a licensed Chatham County contractor solves the problem permanently rather than temporarily.

Hearing Scratching or Squeaking in Your Walls at Night? It Might Be Rats

The most common reason Chatham homeowners call about rats is sound — usually scratching, gnawing, or squeaking inside walls or above the ceiling, almost always at night. Rats are nocturnal — nighttime activity is the dead giveaway. If you're hearing fast scratching, scrabbling, or chewing inside walls or in the attic after dark, particularly between sunset and 2-3 a.m. and again in the pre-dawn hours, you almost certainly have rats. Common sound patterns:

• Scratching in walls at night — the most common report. Rats travel inside wall cavities, nest in insulation between studs, and scratch at the back of drywall. The sound is faster and lighter than squirrel activity, and is concentrated after dark.
• Squeaking and high-pitched chittering — rats vocalize, especially during territorial disputes or when juveniles are present. If you're hearing squeaks coming from inside walls, you have an active colony, not a single animal.
• Sustained gnawing — rats chew constantly to wear down their teeth. Listen for grinding or gnawing sounds, especially on wood structural members or wire insulation.
• Quick, light running across ceiling — roof rats travel along ceiling joists in attic spaces. The sound is fast and rhythmic, very different from the heavy thumping of raccoons.
• Activity continues all night, not just at one time — unlike raccoons (which tend to leave the attic at dusk and return at dawn), rats often have multiple feeding and nesting trips per night, so noise can recur multiple times.

If you're trying to figure out whether it's rats or mice in your walls, the difference is mostly volume and intensity: mice produce lighter, quieter, more sporadic noise; rats produce louder, more sustained, more confident activity. Rats also tend to use specific runways repeatedly, so noise concentrates in particular wall sections. A licensed contractor's inspection identifies species through droppings, grease marks, and runway sign.

Signs You Have Rats in Your Attic, Walls, or Crawl Space

Beyond the noise, here are the signs Chatham homeowners most commonly notice when rats have moved in:

• Rat poop — the single most reliable indicator of an active infestation. Roof rat droppings are about half an inch long, pointed at the ends, and dark when fresh; Norway rat droppings are slightly larger, blunt-ended, and often found in concentrated piles. Do not handle rat droppings without protective equipment — they can transmit hantavirus, leptospirosis, and salmonellosis.
• Grease marks on walls, beams, and travel paths — rats follow the same routes repeatedly, and their fur leaves dark, oily smudges on structural members, baseboards, and around entry points. Grease marks are the single best diagnostic for an established rat colony and don't appear with squirrel or mouse activity.
• A musky rat smell — active rat infestations produce a distinct musky odor that homeowners often describe as 'something died in the wall' even without an actual dead animal. The smell intensifies in warm weather and is particularly strong near nesting sites.
• Dead rat smell — if a rat dies inside a wall cavity, attic, or crawl space, the smell of decomposition is unmistakable and persists for 1-3 weeks. Coastal Georgia humidity and warmth make this smell substantially worse than in cooler climates.
• Gnaw marks on wood, wire, plastic, and food packaging — rats chew through almost anything to widen entry points or access food. Look for fresh chew damage on door frames, baseboards, pantry shelves, and stored materials.
• Visible runways — rats travel the same paths over and over, leaving worn tracks in attic insulation, dust trails on rafters, and faint paths along baseboards.
• Footprints in dust or flour — sprinkling a thin layer of flour along suspected travel paths overnight reveals rat activity by morning.
• Pets fixated on a wall or ceiling area — dogs and cats often hear and react to rat activity homeowners can't detect yet. A pet that suddenly stares at one spot on the ceiling or wall, especially at night, may be tracking a rat.
• Outdoor sign — rat burrows in mulch beds and along foundations, droppings around bird feeders or pet feeding stations, gnawed citrus or fruit (roof rats love citrus, and the climate supports it across coastal Georgia), and dock-area droppings on waterfront properties.

Roof Rats vs Norway Rats — How to Tell Which You Have

Chatham County is unusual because both rat species are well-established and routinely show up in the same property. The species you have determines where they nest, where they enter, and how they need to be excluded — so identifying which is critical to solving the problem.

• Roof rat (Rattus rattus) — also called black rat or palm rat. Slim build, longer than its body tail, agile climber, dark brown to black. Enters at roofline level — gable vents, soffit returns, decayed fascia, attic ridge gaps, and roof-to-wall transitions. Nests in attics, false ceilings, and the upper sections of wall cavities. Heavy population in mature-canopy submarkets across the Savannah Historic District, Ardsley Park, Chatham Crescent, Habersham Park, and the older Eastside neighborhoods. Roof rats followed citrus and tropical food crops up the I-95 corridor during the 1990s-2000s and are now the dominant species in coastal Georgia.
• Norway rat (Rattus norvegicus) — also called brown rat or sewer rat. Heavier-bodied, shorter tail, ground-level entry profile, brown to gray. Enters at foundation level — gaps around plumbing penetrations, crawl-space access points, foundation cracks, and damaged sewer line connections. Nests in basements, crawl spaces, sewers, and ground burrows along property edges. Heavier population in the older inner-city blocks, the industrial-edge neighborhoods of Garden City and Port Wentworth, and along the storm-drainage corridors throughout the county.

The diagnostic tell at the inspection stage is the location of the activity: attic and roofline activity is roof rat; basement, crawl-space, foundation, and ground-level activity is Norway rat. Mixed-species infestations are common in older Savannah Historic District properties, particularly when restaurant-corridor food pressure is high enough to support both populations on a single property. An effective Chatham rat exclusion has to address both species when both are present — sealing the roofline alone leaves Norway rats in the basement, and vice versa.

How Rats Get Into Savannah and Chatham County Homes

Rat entry profiles in Chatham vary by species and by neighborhood. Rats can squeeze through any opening they can fit their head through — for adult roof rats, that's about a half-inch gap; for Norway rats, about three-quarters of an inch. Common entry points across the county:

• Gable vents and louvers — primary roof rat entry, particularly in Historic District, Ardsley Park, and Habersham Park housing where original wood louvers have decayed.
• Decayed soffits and fascia — gaps under eaves and at roof-to-wall transitions are routine roof rat entry, especially in the older intown housing stock.
• Roof-to-wall transitions and dormer junctions — common roof rat entry on Tybee Island, Wilmington Island, and Whitemarsh Island construction with raised foundations and complex rooflines.
• Foundation gaps and crawl-space vents — primary Norway rat entry, particularly in the older inner-city housing and across the Eastside waterfront where crawl-space construction is standard.
• Plumbing penetrations and utility entries — gaps around water lines, sewer lines, and electrical conduit through the foundation are routine Norway rat entry points.
• Damaged or missing sewer line caps — Norway rats travel through storm sewers and access yards through broken cleanouts. Storm-flooding events expand sewer-rat populations into surrounding properties.
• Garage door gaps — both species use gaps under garage doors when other access is limited.
• Pet doors — rats walk through pet doors more readily than homeowners expect.
• Citrus trees, palm trees, and live oak branches touching the structure — roof rats use any vegetation that contacts the roofline as a highway. Trimming back vegetation 4-6 feet from the structure is part of long-term roof rat control in Chatham.

Rat Poop, Pee, and the Smell of an Active Infestation

Rat contamination in your home is more than a smell problem — it's a real disease and structural risk. Here's what's accumulating in your walls, attic, or crawl space when you have an active rat colony:

• Droppings concentrate in nesting and feeding areas — typically dozens to hundreds per active rat per week. In long-running infestations, droppings can accumulate to inches of contamination across the affected attic or crawl space.
• Urine saturates insulation — rat urine has a strong musky smell and contains pathogens that survive after the urine dries. Coastal Georgia humidity prevents complete drying, so contaminated insulation in Chatham attics holds active pathogens longer than in dry inland regions.
• Pheromone trails along travel paths — rats deposit oils and scent markers on travel routes. These trails attract more rats from outside the structure, which is part of why rat infestations rapidly grow into colonies if left unaddressed.
• Dead rats decomposing inside walls — happens regularly when DIY poison is used without an exclusion plan. The smell of a decomposing rat in a wall cavity is distinct, severe, and lasts 1-3 weeks in coastal Georgia conditions. The only solution is to find and remove the carcass, which often requires opening drywall.

Professional rat sanitation uses HEPA-equipped vacuums, full PPE, and decontamination protocols developed for rodent-borne disease environments. Household cleaners and basic vacuum work do not adequately address the contamination — and exposing yourself to rat droppings without proper PPE is a real disease-transmission risk.

Rat Damage and Health Risks — When the Problem Becomes Urgent

Rats cause specific damage and health risks that make a 'wait until next month' approach genuinely dangerous. The job becomes urgent when one of these develops:

• Chewed electrical wiring — like squirrels, rats chew on wire insulation and create fire risk. The risk is highest in older Historic District homes with original cloth-jacketed wiring still in service.
• Flickering lights, tripping breakers, or burning smell — call an electrician AND a wildlife contractor immediately. These are warning signs of imminent fire.
• Smell penetrating into living space — strong musky odor from urine-saturated insulation indicates a multi-week active infestation and substantial contamination footprint.
• Visible droppings in pantry, food storage, or near food prep areas — direct food contamination is a salmonellosis and disease-transmission risk that should not wait for a 'normal' service appointment.
• Pet exposure or fixation — pets that catch and kill rats can pick up rat-borne ectoparasites and pathogens. Pets fixated on wall or ceiling areas suggest active activity behind drywall.
• Rat sighting inside the living space — a rat inside the kitchen, living room, or bedroom indicates the population has grown enough that animals are exploring beyond the typical attic/wall/crawl-space habitat. This is a 'call today' situation.
• Bite or scratch on a person or pet — rat-bite fever is real and the Coastal Health District should be notified for any rat-related bite injury.
• Storm or hurricane recovery — Atlantic hurricane season displaces sewer and outdoor rat populations into structures. After major storms, residential rat call volume across Chatham spikes for 30-60 days.

Are Rats Dangerous? Disease, Bite Risk, and Coastal Concerns

Yes — rats are a documented disease vector and the risks are heightened in coastal Georgia's climate. The major concerns:

• Leptospirosis — bacterial infection transmitted through rat urine. Coastal Georgia's warm, moist climate dramatically increases environmental survival of Leptospira bacteria, particularly in standing water, dock areas, and crawl spaces. Severe in dogs and humans.
• Salmonellosis — bacterial food contamination from rats accessing food storage, pet food, or food prep surfaces. Common cause of acute gastrointestinal illness.
• Hantavirus — viral, transmitted through aerosolized droppings during DIY cleanup attempts. Less common in the Southeast than in the Western U.S. but documented.
• Rat-bite fever — from any rat bite or scratch. Reportable to the Coastal Health District.
• Murine typhus — flea-borne; the fleas that ride rats can transmit typhus bacteria to humans. Documented in coastal Georgia historically.
• Allergic reactions and asthma — rat dander and urine proteins are documented asthma triggers, particularly serious for children with existing respiratory conditions.
• Pet ectoparasites — fleas, mites, and ticks ride rats into living spaces and disperse onto pets after the rats are removed.

The Coastal Health District (Chatham County Health Department) handles disease-exposure investigations and coordinates with the Georgia Department of Public Health on serious cases. This is the main reason DIY rat cleanup without proper PPE is genuinely a health risk, and why professional sanitation matters more than for squirrel work.

How Much Does Rat Removal Cost in Savannah?

Most full Chatham County rat jobs run between $600 and $2,000+ from inspection through final clearance — generally higher than squirrel work because rats require longer monitoring periods, often involve mixed-species coordination, and need more comprehensive sanitation. The variables that move the price:

• Single species vs mixed — mixed roof-rat-plus-Norway-rat infestations require both roofline AND foundation-level exclusion, and run substantially higher.
• Number of entry points — older Historic District properties commonly have 6-10 viable entry points across both rooflines and foundations.
• Insulation contamination scope — multi-month infestations often require full insulation replacement, which adds substantially.
• HVAC ductwork damage — chewed ducts in newer Pooler and Southside subdivisions cost real money in repair plus cooling losses during the work window.
• External food-source pressure — properties near restaurant districts, dumpsters, or storm sewers require ongoing monitoring beyond the initial exclusion to keep populations from re-invading.
• Historic-preservation coordination — required for visible structural work in Historic District and certain designated properties.

Single-species suburban work in newer Pooler or Southside construction at the low end runs $500-$800+; mixed-species work in pre-WWII Historic District housing with extensive contamination can run $3,000+. Phone estimates are free.

How We Remove Rats From Your Home

A typical Chatham County rat removal runs as follows:

1. Inspection (day 1). Full attic, basement, crawl space, foundation, and exterior survey explicitly evaluating both roof rat and Norway rat sign — droppings, runways, gnaw patterns, grease marks, and entry points at both roofline and foundation level. Species and population scope confirmed.
2. Trap installation (day 1-3). Strategic trap placement along confirmed runways. Trapping is the primary removal method; chemical control is used only as a coordinated supplement when trapping cannot reach the population.
3. Active removal (days 3-21). Trapping over a multi-week window as the population is reduced. Activity monitored continuously to confirm the population is collapsing rather than just shifting.
4. Sealing (days 14-30). Permanent closure of every entry point using galvanized steel mesh, copper mesh (rats can chew through aluminum and many other materials), masonry repair, and code-appropriate flashing. Historic-preservation coordination handled where required.
5. Sanitation (days 21-35). HEPA-equipped vacuuming of contaminated insulation, droppings zones, runways, and travel paths. Full antimicrobial decontamination.
6. Repair (days 28-45). Insulation replacement where contamination is heavy, HVAC duct repair, electrical inspection of any wire runs that show chew damage.
7. Monitoring (days 30-60). Confirm the exclusion is complete and no overlooked entry points are still allowing access. The monitoring period is what distinguishes a real rat removal from a temporary fix.

Total timeline: 30-60 days from first call to confirmed clearance. Older Historic District properties with mixed-species infestations and extensive contamination scope run on the longer end. See our full Chatham County wildlife removal coverage for the broader service area.
