Hearing loud thumps, dragging, or rolling sounds above your head at night? That usually isn’t the house

“settling.” In Southern California, it’s often a raccoon using your attic or crawl space as a

nesting site. Raccoons are strong, intelligent, and very determined once they decide your roofline is home.

This guide explains how to recognize raccoon activity, what kind of damage they cause, and how
raccoon removal and trapping works when it’s done legally, humanely,

and professionally by Urban Wildlife Trapping Experts.

Why Raccoons Love Southern California Attics

Raccoons don’t break into attics by accident. They choose them. In Los Angeles County, Orange County,

Riverside County, and San Bernardino County, our mix of older roofs, tile roofs, and aging vents creates easy

access points. Add food sources like trash, fruit trees, pet food, and backyard water, and your property becomes

prime raccoon territory.

Raccoons target:

• Loose or damaged roof tiles, shingles, and ridge caps
• Weak or screened-only attic vents and gable vents
• Soft fascia boards and rotted roof edges
• Crawl space vents and openings around additions and decks

Once they find a weak spot, they pry and pull until they create an opening large enough to squeeze through. From

there, they begin nesting, breeding, and using your attic like a high-rise den.

Common Signs of Raccoons in the Attic

Homeowners often call us after weeks or months of ignoring noises because they seemed “too loud” to be

an animal. But raccoons are big, strong, and heavy. Here are the most common signs we see across
Los Angeles County,
Orange County,
Riverside County, and
San Bernardino County:

• Loud thumps and walking sounds above ceilings, especially at night
• Rolling or dragging sounds as they move objects or insulation around
• Scratching and ripping noises near eaves or walls
• Strong odor from droppings and urine in the attic or certain rooms
• Visible roof damage around vents, corners, and roof edges
• Raccoon sightings on your roof, fence, or near pet food and trash cans

If you’re hearing noise in the attic but aren’t sure what it is, our
Urban Wildlife Blog and
raccoon removal and trapping service page work together to help you

identify what’s going on and what to do next.

Damage Raccoons Cause Inside Attics

Raccoons are powerful animals. Once inside, they can quickly turn a clean attic into a contaminated mess. During

inspections, we commonly find:

• Torn and flattened insulation used for nesting
• Droppings and urine saturation spread across the attic floor
• Chewed ductwork and flexible vents leading to lost heating and cooling efficiency
• Damaged wiring that can create fire hazards
• Stained and weakened drywall from urine soaking down

Beyond the physical damage, raccoon droppings can carry parasites and bacteria that are unsafe to breathe around.

Leaving a raccoon problem in place rarely stays “just noise.” It usually turns into a full
attic cleaning and insulation replacement project if

it goes on long enough.

Health Risks Linked to Raccoon Infestations

Raccoons are wild animals, and with them come potential health risks. Some of the main concerns include:

• Roundworm eggs present in raccoon droppings
• Leptospirosis and other bacteria spread through urine
• Fleas and ticks carried in on their fur

This is why safe cleanup procedures, protective equipment, and proper disposal of contaminated materials are so

important. A raccoon job is never just “set a trap and leave.” It’s about restoring a healthy

space for the people living below.

How Humane Raccoon Removal & Trapping Works

At Urban Wildlife Trapping Experts, our approach to
raccoon removal and trapping is built around three priorities:

protecting your family, protecting your home, and treating wildlife humanely and legally.

1. Full Inspection

We start with a detailed inspection of the roofline, attic, crawl space, and exterior. Our goal is to find:

• The main entry and exit holes raccoons are using
• Secondary weak spots likely to become future entries
• Evidence of nesting, droppings, and damage inside the attic or crawl space

2. Customized Trapping Plan

Based on what we find, we design a trapping plan that follows California law and focuses on safe, humane capture. We

avoid cheap shortcuts that create suffering or unnecessary risk to pets and non-target animals.

Traps are placed strategically near active entry points and travel paths. We walk homeowners through what to expect

and how to monitor the situation between our visits.

3. Removal, Exclusion & Repairs

Once raccoons are removed, we seal and reinforce entry points so the problem doesn’t restart the next week.

Depending on the home, exclusion work may include:

• Screening and reinforcing attic vents and gable vents
• Repairing roof edges, fascia, and gaps in the eaves
• Securing crawl space vents and foundation openings

When contamination is severe, we recommend
attic cleaning and insulation replacement so you’re

not living under droppings, urine, and damaged materials long-term.

DIY Raccoon Control vs. Calling a Professional

We understand the temptation to try DIY traps or online repellents. The problem is that raccoons are extremely smart

and very strong. Common DIY issues we see include:

• Trapping one raccoon while leaving babies behind in the attic
• Blocking an entry hole before all raccoons are out, causing panic and more damage
• Using the wrong type of trap placement, creating risk for pets or neighbors
• Relying on sprays and home remedies that don’t actually fix the entry points

Professional raccoon removal and trapping focuses on the whole situation:

the animals, the structure, the contamination, and long-term prevention. It’s not just about catching

“something.” It’s about solving the problem correctly the first time.

When to Call Urban Wildlife Trapping Experts

You don’t need to see a raccoon face-to-face to have a serious problem. It’s time to call in help if:

• You hear heavy walking, thumping, or rolling noises in the attic or crawl space
• You notice roof damage, torn vents, or new openings around the eaves
• You find droppings, insulation pulled back, or strong odors in specific rooms
• Pets are alert, barking, or staring at walls and ceilings at night

Urban Wildlife Trapping Experts provides humane
raccoon removal and trapping across Southern California, including
Los Angeles County,
Orange County,
Riverside County, and
San Bernardino County.
