Critter Removal: Ultimate 2025 Guide
When Your Home Becomes a Wildlife Haven
Critter removal is the professional service of identifying, humanely removing, and preventing the return of unwanted wildlife from your property. If you’re hearing scratches in the walls or noises from the attic, you likely need help from a licensed wildlife control specialist.
Professional critter removal follows a proven process that not only gets wildlife out but keeps them out permanently. Services typically include:
- Inspection: Identifying the animal and all entry points.
- Removal: Safely trapping and removing wildlife using humane methods.
- Exclusion: Sealing entry points to prevent re-entry.
- Cleanup: Sanitizing affected areas and removing contaminated materials.
- Repair: Fixing damage to insulation, wiring, and structures.
Common critters that invade Massachusetts homes:
- Squirrels, raccoons, rats, mice, bats, skunks, opossums, and snakes.
Wildlife seeking shelter often choose attics, chimneys, and crawl spaces, especially during cold weather. What starts as a few scratches can quickly become a serious problem involving damaged wiring, contaminated insulation, and health risks. Unlike DIY attempts that often fail, trained specialists know how to identify species, remove them safely, seal entry points, and restore your home.

Identifying the Unwanted Guest: Common Critters & Telltale Signs
Figuring out who’s moved into your attic is the first step in effective critter removal. Each type of wildlife leaves unique clues—different sounds, droppings, and damage. Understanding these signs helps create the right removal strategy. While not “normal,” having animals in your attic is incredibly common in Eastern Massachusetts, as it offers shelter from predators and weather. Let’s explore the most frequent uninvited guests.
Squirrels
These are the champions of attic invasions. You’ll hear them in the early morning or late evening—persistent scurrying, scratching, and the sound of nuts rolling across the floor.
Squirrel droppings resemble large brown rice grains. The real trouble is their relentless chewing on wood, insulation, and electrical wires, which creates a serious fire hazard. They can squeeze through 1.5-inch openings and build nests from your insulation.

Raccoons
If squirrels are acrobats, raccoons are heavyweight wrestlers. You’ll hear loud thumping and heavy walking, almost always at night. These intelligent and strong animals can tear apart vents and rip off shingles.
Raccoon droppings are large and dark, often found in concentrated “latrines.” They need about 4 inches of space to enter and leave five-toed tracks. Whining or chattering sounds often indicate a mother with her babies.

Rodents (Rats & Mice)
Don’t let their size fool you; rats and mice are highly problematic. Active at night, you’ll hear gnawing or scratching from inside walls or ceilings. Their teeth never stop growing, so they must chew constantly.
Rodent droppings are small, dark, and pellet-shaped. You may also see oily rub marks along baseboards. Mice can squeeze through openings as small as a dime (¼ inch), while rats need slightly more space, making even well-sealed homes vulnerable.

Bats
Bats are quiet invaders. You might only notice them around dusk or dawn, listening for chirping or squeaking as they enter or exit.
The most obvious sign is guano (droppings), which looks like black rice and accumulates in piles below their roost. You might also spot brown or gray smudges near entry points. Bats can squeeze through openings as small as half an inch.

Other Wildlife
Other critters might settle on your property. Opossums are nocturnal and make hissing or screeching sounds, leaving sizable droppings. Snakes can enter through small cracks, often following rodents, and shed skins are a clear sign. Skunks prefer denning under decks or porches, and their unmistakable musky odor is the primary clue.
The Dangers Lurking in Your Home: Damage and Health Risks
When wildlife moves in, they create real problems for your property and health. A “minor” issue can quickly turn into thousands of dollars in repairs and expose your family to serious risks. This is why professional critter removal is so important.
Property Damage Caused by Critters
The damage compounds quickly. Rodents and squirrels constantly gnaw, and chewed electrical wires are a major fire hazard. They also tear through insulation to build nests, which ruins your home’s energy efficiency and increases utility bills.
Larger animals like raccoons can destroy HVAC ductwork, contaminating your air supply with dust and animal waste. Persistent gnawing can also lead to weakened wooden beams, compromising your home’s structural integrity. Finally, soiled ceilings and walls from urine and feces create stubborn stains and odors that are difficult to remove.
Health Risks Associated with Wildlife Infestations
The health concerns are significant and should not be ignored.
- Histoplasmosis: A respiratory disease caused by a fungus in bat guano. Spores become airborne when disturbed.
- Salmonella & Leptospirosis: Bacteria from rodent droppings and urine can cause severe gastrointestinal illness and lead to kidney or liver damage.
- Rabies: A fatal viral disease carried by raccoons and bats. Any bite or direct contact requires immediate medical attention.
- Parasites: Wildlife can bring fleas, ticks, and mites into your home, which can infest pets and bite family members, spreading diseases like Lyme disease.
Some DIY “solutions” also pose health risks. Mothballs, for instance, are carcinogenic and ineffective. The longer wildlife remains, the greater the risks to your property and family’s health.
The Professional Critter Removal Process: A Step-by-Step Guide
At Waltham Pest Control, we use a comprehensive, multi-step process that provides a long-term solution, not a temporary fix. Our approach is built on humane methods and over 40 years of experience. Simply removing a critter without sealing the entry point is like bailing water from a boat without patching the hole. Our process ensures they don’t come back.
Step 1: Comprehensive Wildlife Inspection
Every successful critter removal begins with a thorough inspection. Our licensed specialists examine your property from the roofline to the foundation to find every vulnerability.
- Identify the species: We determine exactly what we’re dealing with by analyzing noises, droppings, and damage patterns.
- Locate all entry points: Critters often have multiple ways in and out. We inspect every potential access point, from roof vents to foundation cracks.
- Assess the damage: We check for torn insulation, chewed wires, and other damage to understand the full scope of the problem.
- Create a custom plan: Based on our findings, we develop a removal plan custom to your specific situation.

Step 2: Humane Critter Removal
We are committed to resolving conflicts between wildlife and homeowners ethically. All our methods prioritize animal welfare and adhere to Massachusetts state and local regulations.
- Live Trapping: We use traps designed to capture animals safely without injury, and we check them frequently to minimize stress.
- One-Way Exclusion Doors: This highly effective technique allows animals to exit your home but prevents them from re-entering. It’s ideal for ensuring mothers and babies can reunite outside.
- Species-Specific Techniques: We understand the behavior of each species and adapt our methods accordingly, especially when dealing with mothers and their young.
- Relocation Protocols: We follow all legal guidelines for relocation, releasing animals in appropriate habitats where they can thrive.
Step 3: Exclusion and Prevention to Stop Re-entry
Getting critters out is half the battle; keeping them out is critical. Our exclusion work is designed to provide a permanent solution.
- Seal Cracks and Holes: We seal every opening, even those as small as ¼ inch, using professional-grade materials that animals can’t chew through.
- Install Chimney Caps: A durable cap blocks animal access to your chimney while allowing proper ventilation.
- Secure Vents: We protect gable, roof, and soffit vents with heavy-duty mesh guards that prevent entry without restricting airflow.
- Trim Tree Branches: We recommend keeping branches at least six to eight feet from your roof to eliminate easy access routes for squirrels and raccoons.
- Secure Attractants: We advise on securing trash cans and other outdoor items that might attract wildlife.
Step 4: Cleanup, Sanitation, and Damage Repair
The final step is addressing the mess and damage left behind, which is crucial for your health and for preventing future infestations.
- Remove Contaminated Materials: We safely remove and dispose of insulation and other materials soiled with urine and droppings.
- Disinfect and Deodorize: We use professional-grade, enzyme-based products to eliminate bacteria, viruses, and lingering odors that can attract new critters.
- Repair Damage: We address safety hazards like chewed electrical wires and repair damaged structural wood to ensure your home’s integrity.
- Attic Restoration: For severe cases, we offer complete attic restoration, which can include replacing insulation, repairing ductwork, and treating for any parasites left behind. We return your attic to a clean, safe, and energy-efficient space.
Frequently Asked Questions about Critter Removal Services
It’s natural to have questions when dealing with unwanted wildlife. Here are answers to the most common ones we’ve heard over our 40+ years serving Eastern Massachusetts.
How much does professional critter removal cost?
The honest answer is: it depends. The cost of critter removal reflects the unique challenges of your situation. Factors include the type of animal, the location of the infestation (attic vs. inside a wall), and the extent of the damage. A simple removal is less costly than a job requiring full attic restoration and repairs. Because every situation is different, we provide detailed, transparent estimates only after a thorough inspection to determine the exact scope of work required.
Are professional removal methods humane?
Absolutely. At Waltham Pest Control, humane treatment of wildlife is a core principle. We use live traps and one-way exclusion doors that allow animals to leave safely. Our specialists are trained in safe handling techniques that minimize stress, and we take special care to keep mothers and their young together. We strictly follow all Massachusetts state regulations for removal and relocation, and we never use harmful poisons or toxins.
What are the dangers of DIY critter removal?
While tempting, DIY critter removal is risky and often makes the problem worse.
- Personal Injury: Cornered wildlife can bite or scratch, and animals like raccoons and bats can transmit rabies. There’s also the physical danger of falling from ladders.
- Disease Exposure: Without proper protective gear, you risk exposure to diseases like histoplasmosis from bat guano or leptospirosis from rodent urine.
- Legal Consequences: Many species are protected by state laws, and improper removal can lead to fines.
- Ineffective and Worsening the Problem: Sealing the wrong hole can trap animals inside, where they may die and cause a terrible odor. You might also separate a mother from her babies, leaving them to starve in your walls. Popular DIY methods like mothballs are carcinogenic and ineffective.
Calling a professional at the first sign of a problem is the safest and most effective solution. Our team serves communities throughout Eastern Massachusetts and is ready to help you solve your wildlife problem permanently.
