The best way to stop animals from nesting in your Myrtle Beach chimney is a combination of physical barriers (chimney caps, screens), routine inspections, and professional sweeping. Most infestations start with small entry points, like cracks in the crown or gaps around the flue, that homeowners miss until debris or smoke backs up. If you hear scratching or see nests, call a chimney sweep immediately to avoid structural damage or fire hazards. Prevention costs far less than repairs after an animal takes up residence.
What is a chimney animal infestation, and why do Myrtle Beach homes get them?
A chimney animal infestation happens when squirrels, raccoons, birds, or even snakes use your chimney as shelter, nesting material, or a food source. Myrtle Beach’s humid subtropical climate, with its hot summers and mild winters, creates ideal conditions for these pests. The coastal area’s mix of older brick homes, pine-needle debris, and open flues (especially in vacation rentals) makes chimneys particularly inviting. Animals target chimneys because they’re dark, enclosed, and often left unchecked during off-seasons. A single squirrel can block a flue with nesting material in weeks, while birds like starlings or sparrows can create thick mud nests that trap creosote and reduce airflow to dangerous levels.
Most homeowners in Myrtle Beach don’t realize their chimney is compromised until they notice one of these red flags: smoke backing into the room, a strong musty odor, or, worst of all, a fire hazard from blocked airflow. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) reports that animal nests are a leading cause of chimney fires in coastal regions, often because homeowners ignore early signs until it’s too late. If you’ve seen birds flying in and out of your chimney or heard scratching at night, your flue is already at risk.
The key to prevention is understanding how animals enter. Most start with small gaps: a loose chimney cap, cracks in the crown, or even a missing damper. Myrtle Beach’s salt air accelerates masonry deterioration, so older homes near the ocean (like those in North Myrtle Beach or Surfside Beach) are especially vulnerable. A professional chimney sweep can identify these entry points during an inspection and recommend sealing solutions before animals exploit them. Learn more about chimney inspections in Myrtle Beach.
Myth: 'If I can’t see animals, my chimney is fine.' Fact: Most Myrtle Beach infestations start with tiny clues homeowners ignore.
Homeowners often assume their chimney is safe if they don’t see animals, until it’s too late. The truth is, animals like squirrels and birds leave subtle signs long before they fully occupy your flue. For example, a single squirrel can chew through a chimney cap’s mesh in days, creating just enough space to drag in nesting material. By the time you notice feathers, twigs, or droppings around the fireplace, the nest may already be deep inside, blocking 50% or more of your flue’s diameter.
In Myrtle Beach, where many homes sit vacant for weeks during summer or winter, animals have even more opportunity to move in unnoticed. A raccoon or opossum might use your chimney as a dry shelter during a rainstorm, while European starlings, common in the area, build nests that can weigh 20 pounds or more, putting stress on masonry. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) warns that even small nests increase the risk of creosote buildup, which is highly flammable. If you’ve ever smelled a rotten-egg odor near your fireplace, it could mean an animal has died inside and begun to decompose.
The best way to catch these early is to look for these Myrtle Beach-specific warning signs: - Feathers or twigs around the fireplace or on the roof near the chimney. - Scratching or scurrying noises coming from the chimney at night (common with squirrels or raccoons). - Smoke that doesn’t rise or lingers in the room instead of exiting through the flue. - Bird droppings on the chimney cap or ledge, which can erode mortar over time. - A sudden drop in heat output from your fireplace, signaling restricted airflow.
If you spot any of these, schedule a chimney sweep immediately. Many homeowners wait until they see an animal’s tail or hear rustling, by then, the damage (and cost) is far worse. Need help identifying signs? Check our Myrtle Beach chimney troubleshooting guide for a step-by-step checklist.
How to physically block animals: Chimney caps, screens, and Myrtle Beach-specific solutions
The most effective way to stop animals is to eliminate their access points. A properly installed chimney cap with a tight-fitting mesh (1/4-inch or smaller) can block 99% of pests, including squirrels, birds, and even snakes. However, not all caps are created equal, especially in Myrtle Beach’s humid, salt-corrosive environment. Cheap caps made from thin aluminum or plastic can rust or warp within a year, leaving gaps for animals to exploit. For coastal homes, stainless steel or heavy-gauge galvanized steel caps last longer and resist corrosion better.
Here’s what works best for Myrtle Beach homes: - Top-sealing caps: These create a physical barrier over the flue, preventing animals from entering while still allowing smoke to escape. They’re ideal for homes with open flues or those near dense pine forests (like areas around Huntington Beach State Park), where falling branches could introduce debris. - Mesh screens: Installed inside the flue, these are less visible but highly effective. They’re often used in conjunction with caps for added security. The mesh should be fine enough to stop birds but still allow proper draft. - Damper seals: If your damper has gaps, a flexible seal or a new damper can block entry while improving efficiency. Older homes in Garden City or Murrells Inlet often have worn dampers that need replacement.
Installation matters just as much as the product. A poorly fitted cap can leave gaps at the sides or base, making it useless. Many DIY attempts fail because homeowners underestimate the precision required, especially on sloped or damaged chimneys. For Myrtle Beach’s mix of brick, stucco, and modern masonry, a professional chimney sweep can ensure the cap is sealed correctly and won’t blow off in high winds (a common issue near the beach). See our guide on choosing the right chimney cap for Myrtle Beach homes for recommendations tailored to local conditions.
Costs vary based on materials and chimney height, but a quality stainless steel cap in Myrtle Beach typically ranges from $150 to $400 installed. This is a fraction of the cost of repairing a chimney after an animal infestation, where nests can require full flue relining or even masonry repairs. If your home is in a high-risk area (like near a wooded lot or close to the ocean), investing in a cap now can save thousands later.
What most people get wrong about DIY animal removal: Why you should never try this alone in Myrtle Beach
Many homeowners in Myrtle Beach attempt to remove animal nests themselves, often using tools like shop vacuums, brooms, or even their hands. This is a dangerous mistake. First, animals like raccoons or skunks can carry diseases like rabies or leptospirosis, and their bites or scratches require medical attention. Second, disturbing a nest can cause the animal to panic and scratch at the flue lining, creating new cracks or holes. Third, if the nest is deep or the animal is trapped, you risk suffocating it inside the chimney, leading to a foul odor and potential mold growth.
The EPA the U.S. Environmental Protection Agency advises against DIY animal removal in enclosed spaces like chimneys due to the risk of exposure to feces, urine, and nesting materials that may contain fungi or parasites. In Myrtle Beach’s heat and humidity, these materials can also decompose rapidly, releasing toxic gases. A professional chimney sweep uses specialized tools, like flexible rods and high-powered vacuums, to safely remove nests without harming the animal or damaging the chimney.
Another common mistake is assuming that once the animal is gone, the problem is solved. In reality, the nest itself can leave behind creosote, debris, and even structural damage. A chimney sweep will inspect the flue for: - Creosote buildup from the animal’s presence, which increases fire risk. - Masonry cracks caused by the animal’s movements or nest weight. - Lining damage from sharp claws or beaks. - Residual odors that require cleaning to prevent mold.
If you’ve already attempted removal and notice smoke backing up, a strong smell, or reduced draft, call a professional immediately. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends that any chimney with a confirmed animal infestation should be inspected and cleaned by a certified sweep before use.

How often should you inspect for animals in Myrtle Beach? Seasonal risks and local factors
Myrtle Beach’s climate and housing patterns mean animal infestations don’t follow a one-size-fits-all schedule. Vacation rentals, for example, are at higher risk because they’re often left unoccupied for weeks, giving animals free rein. Permanent residents should follow this localized approach:
- Spring (March–May): This is peak nesting season for birds and squirrels. If you’ve had your chimney capped but notice increased bird activity, inspect the cap for damage or gaps. The humidity in spring can also cause wood nests to swell, blocking flues. - Summer (June–August): While many animals avoid the heat, raccoons and opossums may seek shade in chimneys. If your home is near wooded areas (like near the Intracoastal Waterway or the Pawleys Island Highway), be extra vigilant. - Fall (September–November): Squirrels and chipmunks prepare for winter by nesting in warm, enclosed spaces. This is the most critical time for inspections, especially before holiday fireplace use. - Winter (December–February): While animals are less active, a dead animal in your chimney can pose a serious fire hazard. If you haven’t used your fireplace in months, schedule a sweep before lighting it.
For Myrtle Beach homeowners, the CSIA recommends an annual inspection, but if your chimney is older, near wooded areas, or used infrequently, you may need bi-annual checks. Vacation rental owners should inspect before and after each guest season. See our seasonal chimney prep guide for Myrtle Beach to stay ahead of pests.
Pro tip: If you hear animals in your chimney during the day (unlike nocturnal squirrels), they’ve likely taken up permanent residence. Don’t wait, schedule a sweep within 48 hours to avoid further damage. Many sweeps in Myrtle Beach offer emergency service for active infestations, including after-hours calls for urgent situations.
Chimney sweep vs. pest control: Who should you call for Myrtle Beach animal infestations?
This is a question we hear often in Myrtle Beach: Should I call a chimney sweep or a pest control company? The answer depends on the severity of the infestation. Here’s how to decide:
- Call a chimney sweep if: - You’ve already confirmed an animal is inside (e.g., you see feathers, droppings, or hear scratching). - The chimney shows signs of damage (cracks, missing mortar, or a damaged cap). - You need a full inspection and cleaning of the flue, not just removal. - You want to ensure the chimney is safe for future use (sweeps check for creosote, lining integrity, and draft issues). - Call pest control if: - The animal is still outside the chimney (e.g., squirrels in the attic or birds on the roof). - You need humane trapping or exclusion services before sealing the chimney. - The infestation is part of a larger pest problem in your home.
In Myrtle Beach, many homeowners make the mistake of calling pest control first, only to find the technician can’t safely remove the animal without risking damage to the chimney. A certified chimney sweep has the training to handle both the animal and the chimney structure. For example, if a raccoon has chewed through your flue liner, a sweep can assess whether it needs repair or replacement, something a pest control service won’t catch.
That said, some pest control companies specialize in chimney-specific animal removal and work alongside sweeps. If you’re unsure, start with a chimney inspection. Many sweeps in Myrtle Beach, like ours, offer free estimates and can coordinate with local pest control if needed. Need help finding a licensed sweep in your area?

| Season | Animal Risks | Prevention Steps | Recommended Action |
|---|---|---|---|
| Spring (Mar–May) | Birds (starlings, sparrows), squirrels preparing nests | Check chimney cap for gaps, install mesh screens if needed | Inspect before nesting season peaks |
| Summer (Jun–Aug) | Raccoons, opossums seeking shade | Seal cracks in masonry, ensure cap is corrosion-resistant | Inspect after heavy rains (salt air accelerates wear) |
| Fall (Sep–Nov) | Squirrels, chipmunks nesting for winter | Remove leaves/debris from cap, reinforce weak points | Full sweep before holiday fireplace use |
| Winter (Dec–Feb) | Dead animals trapped in flue | Avoid using fireplace if you hear scratching | Emergency sweep if you smell decay or see smoke backup |
Frequently Asked Questions
My chimney cap is intact, but I still hear squirrels at night. What’s happening?
Squirrels can enter even with a cap if there’s a gap between the cap and the chimney’s inner flue, or if they’ve chewed through the mesh. Myrtle Beach’s humidity can also cause metal caps to warp over time, creating tiny openings. Check for rust or bending around the cap’s edges, if you see daylight through the seams, the cap needs replacement. Never ignore nighttime scratching; a single squirrel can block your flue in weeks, turning your next fire into a smoke-filled disaster.
I found bird nests in my chimney last winter. Do I need a full sweep, or can I just remove the nests?
You must schedule a full chimney sweep after removing bird nests, even if the nests seem small. Bird nests trap moisture, which accelerates creosote buildup and can weaken your flue liner. In Myrtle Beach’s damp climate, this moisture also promotes mold growth, which spreads into your home’s air supply. A sweep will clean the flue, check for damage, and ensure no nest material remains, especially in hard-to-reach spots where birds often hide eggs or lining.
My neighbor’s chimney has a cap, but squirrels keep getting in. What’s the best fix?
If squirrels bypass your cap, the issue is likely poor installation or an older, damaged cap. Myrtle Beach’s salt air corrodes cheap caps quickly, leaving gaps. Upgrade to a top-sealing cap with a tight mesh (1/4-inch or smaller) and have it professionally installed to seal any gaps between the cap and the chimney’s outer structure. Some sweeps also recommend adding a chimney screen inside the flue as a secondary barrier. Avoid DIY fixes like caulk or hardware cloth, these can trap heat and create fire hazards.
I smell something dead in my chimney. Is this an emergency?
Yes, this is a fire and health emergency. A dead animal in your chimney decomposes quickly in Myrtle Beach’s heat, releasing toxic gases and creating a severe fire risk from trapped creosote. Do not attempt to remove it yourself, call a chimney sweep immediately. They’ll use specialized tools to extract the remains safely, clean the flue, and check for structural damage. Until then, do not use your fireplace, the fumes can be deadly.
