If you hear scratching in your chimney, it’s almost always animals nesting. In Myrtle Beach, raccoons, birds, and squirrels are the most common culprits, especially after summer storms or during cooler months. The safest course is to call a licensed chimney sweep to remove the nest and inspect for damage, never attempt removal yourself, as live animals or eggs can pose health risks. Routine chimney sweeps (twice yearly for wood-burning fireplaces) help prevent nests by keeping the flue clear of debris, which is the first step animals use to build their homes. If you’ve already spotted signs like feathers, droppings, or a foul odor, schedule an inspection immediately to avoid structural damage or fire hazards.
What ‘scratching’ in your chimney actually means, and why it’s not just a minor nuisance
Most Myrtle Beach homeowners assume scratching in the chimney is just a harmless animal exploring. But in reality, it’s almost always the first sign of a nest being built. The coastal humidity and frequent summer storms create ideal conditions for birds, raccoons, and squirrels to seek shelter in chimneys. These animals don’t just scratch, they shred insulation, chew through mortar joints, and leave behind droppings that corrode metal and masonry over time. The longer you wait, the more damage occurs. For example, a single raccoon nest can weigh 20–30 pounds, putting stress on the chimney crown and flue liner. Birds like starlings or sparrows may seem less threatening, but their nests can block airflow entirely, forcing smoke into your home, a serious fire and carbon monoxide risk.
The key is recognizing the type of scratching. Light, high-pitched noises often mean birds, while deep, rhythmic scraping usually indicates raccoons or squirrels. If you also notice feathers, twigs, or a strong ammonia-like smell near the fireplace, animals are already established. Myrtle Beach’s older neighborhoods, especially those near Huntington Beach State Park or the Intracoastal Waterway, see more animal activity due to the mix of mature trees and unmaintained chimneys. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) warns that even a small nest can reduce chimney efficiency by up to 40%, making your fireplace less safe and less effective.
What to do immediately: Stop using the fireplace. The heat and smoke can agitate animals, increasing the risk of them falling into your home or damaging the nest further. Instead, call a professional chimney sweep to assess the situation. Many homeowners in Myrtle Beach wait until they see droppings or hear noises at night, by then, the cleanup is more expensive and the chimney may need repairs. Learn more about chimney inspection damage assessments in our Myrtle Beach guide.
A chimney inspection is a thorough examination of your chimney’s structure, flue condition, and any obstructions, including animal nests, debris, or damage, before cleaning begins.
A chimney inspection goes beyond just peeking inside the flue. It’s a detailed assessment of every component: the crown (top of the chimney), flue liner, smoke chamber, and even the mortar joints. When animals nest in your chimney, they leave behind more than just feathers and twigs, they damage the chimney itself. Raccoons, for instance, will tear apart insulation and chew through thin metal liners, while birds like chimney swifts (yes, they’re real and common near Myrtle Beach’s marshes) can pack their nests with mud, clogging the entire flue. During an inspection, a certified sweep will check for: - Structural damage: Cracks in the masonry, loose bricks, or a compromised chimney crown (a favorite entry point for animals). - Obstructions: Nests, leaves, or even dead animals blocking airflow. - Corrosion: Rust on metal components or acid erosion from animal urine. - Safety hazards: Gaps where smoke or sparks could escape into your home.
In Myrtle Beach, where older homes with brick chimneys are common, inspections are especially critical. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) states that chimneys with nests have a 3x higher risk of chimney fires due to blocked airflow and flammable nesting materials. Many homeowners in Surfside Beach or Garden City areas assume their chimneys are fine until they smell something rotten or see droppings on their fireplace hearth. By then, the damage might require costly repairs, or worse, a full chimney relining.
Pro tip for Myrtle Beach homeowners: If your chimney hasn’t been inspected in over a year, schedule one before you hear scratching. Animals are drawn to chimneys that already have debris or cracks. A routine sweep (which includes inspection) can catch these issues early. See our checklist for new Myrtle Beach homeowners to avoid these pitfalls.
‘I’ll just wait until spring’, why delaying animal removal in Myrtle Beach is a costly mistake
This is the most common mistake we see in Myrtle Beach, especially after the summer season. Homeowners think, ‘It’s too hot for animals to be active, so I’ll deal with it later.’ But here’s the problem: animals don’t follow your schedule. Raccoons, for example, are most active at dawn and dusk year-round, and birds like European starlings (an invasive species thriving in Myrtle Beach’s climate) start nesting as early as February. By the time you’re ready to tackle the issue, the nest could be larger, the damage more extensive, and the cleanup more dangerous.
Consider this scenario: A home near Little River’s marshes had a squirrel nest go undetected for six months. By the time the homeowner noticed the scratching, the squirrels had chewed through the flue liner, leaving sharp metal edges inside the chimney. The repair cost? Over $2,000, not including the lost heat efficiency and potential fire risk. Meanwhile, a nest removed in its early stages (when animals are still scouting) often costs between $150–$400 for cleanup and inspection, with no additional repairs needed.
Another risk of delaying removal is the health hazard. Animal droppings contain fungi, bacteria, and parasites that can contaminate your home. The U.S. Environmental Protection Agency the U.S. Environmental Protection Agency warns that inhaling dust from old nests can cause histoplasmosis, a serious lung infection. Myrtle Beach’s humid climate accelerates mold growth in nests, making the problem worse over time.
Local example: Last year, a family in Murrells Inlet called us in October after hearing scratching for weeks. The nest turned out to be a family of raccoons, and the chimney had sustained water damage from their activity. The repair bill? Nearly $3,500. If they’d acted when they first heard the noises, the cost would’ve been a fraction of that. Learn how to spot early warning signs in our North Myrtle Beach prevention guide.
How Myrtle Beach’s climate makes chimneys more vulnerable to animal intrusions
Myrtle Beach’s coastal environment creates the perfect storm for animal nesting in chimneys. The combination of high humidity, frequent storms, and the region’s mix of older homes and vacation rentals makes chimneys especially attractive to wildlife. Here’s how local conditions play a role:
1. Humidity and Rain: After a summer storm, chimneys can develop cracks or loose mortar. Animals like raccoons and opossums use these gaps as entry points. The moisture also weakens wood and insulation, making it easier for animals to tear through. 2. Mature Trees: Neighborhoods like Fantasy Harbour or the areas near the Intracoastal Waterway have dense tree cover, providing easy access for squirrels and birds to scout chimneys. 3. Unoccupied Homes: Vacation rentals and second homes in Myrtle Beach are prime targets because animals know they won’t be disturbed. Even if you’re not using your fireplace, a chimney left unattended is an open invitation. 4. Coastal Winds: Strong winds can dislodge chimney caps or loosen bricks, creating larger openings for animals to enter.
The EPA’s Burn Wise program the EPA's Burn Wise program highlights that chimneys in humid climates are 25% more likely to develop animal nests due to the conditions above. If you’ve noticed more birds or raccoons in your area, especially near construction sites or overgrown lots, your chimney is at higher risk.
Prevention tip: Install a stainless steel chimney cap with a mesh screen (1/4-inch or smaller) to block animals while allowing smoke to escape. In Myrtle Beach, where hurricanes can damage chimneys, a heavy-duty cap is a smart investment. See our guide on chimney cap installation for Myrtle Beach homes.
The step-by-step process for safe animal removal and nest cleanup in Myrtle Beach
Removing an animal nest from your chimney isn’t a DIY job, it’s a multi-step process that requires safety gear, the right tools, and knowledge of local wildlife. Here’s what a professional chimney sweep does to handle the job safely:
1. Assessment: The sweep starts with a Level 2 inspection (the most thorough type) to evaluate the extent of the damage, the type of animal involved, and any structural weaknesses. This includes using a chimney camera to inspect the flue without disturbing the nest. 2. Humane Removal: If the nest contains live animals or eggs, the sweep will use exclusion methods (like one-way doors or deterrents) to encourage the animals to leave on their own. In Myrtle Beach, we’ve had success with live traps for raccoons and bird netting for starlings, but these must be placed correctly to avoid harming the animals. 3. Nest Removal: Once the animals are gone, the nest is carefully extracted using long-handled tools to avoid contact with droppings or nesting materials. The sweep will also check for signs of disease or parasites. 4. Cleaning and Disinfection: The flue is scrubbed with industrial-grade cleaners to remove soot, debris, and any remaining organic matter. This step is critical to prevent mold growth and odors. 5. Repairs: If the inspection reveals damage, such as cracked mortar, rusted liners, or a compromised crown, the sweep will recommend and perform the necessary repairs before the chimney is deemed safe for use.
What you shouldn’t do: - Don’t use pesticides or traps yourself. This can harm the animals or leave toxic residue in your chimney. - Don’t flush the nest down the toilet or burn it. Animal nests can contain harmful pathogens, and burning them releases toxic fumes. - Don’t ignore the problem. Even after removal, schedule a follow-up inspection to ensure no damage was missed.
Cost considerations: In Myrtle Beach, animal removal and nest cleanup typically ranges from $200–$600, depending on the size of the nest, the type of animal, and any repairs needed. For example, removing a raccoon nest with minor damage might cost around $300, while a large bird nest requiring liner repairs could reach $500–$600.

‘I’ve heard animals can be removed with smoke’, why this myth is dangerous in Myrtle Beach homes
This is one of the most persistent (and dangerous) myths we encounter in Myrtle Beach. Some homeowners believe that lighting a small fire or using ‘smoke bombs’ will scare animals out of the chimney. The reality? This method is not only ineffective but also extremely hazardous. Here’s why:
- Animals don’t leave. Raccoons, squirrels, and birds are used to smoke and won’t be deterred by a small fire. In fact, the heat can make them more aggressive, increasing the risk of them falling into your home. - Fire risk. A blocked chimney with a nest inside can cause creosote buildup to ignite, leading to a chimney fire. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that chimney fires are 5x more likely when nests are present. - Toxic fumes. Burning a nest releases ammonia, methane, and other harmful gases, which can fill your home and cause respiratory issues. - Legal consequences. In South Carolina, attempting to remove wildlife from your property without proper licensing can result in fines, especially if the animals are protected species (like certain birds).
What actually works: If you suspect an animal is in your chimney, the safest approach is to stop using the fireplace immediately and call a professional. Many Myrtle Beach homeowners make the mistake of trying to ‘smoke them out’ during cooler months, only to end up with a chimney fire or a nest that’s now larger and harder to remove. See our emergency chimney fire prevention guide for Myrtle Beach.
How often should you schedule a chimney sweep in Myrtle Beach to prevent animal nests?
The answer depends on how often you use your fireplace and the type of fuel you burn. But in Myrtle Beach’s climate, we recommend at least two sweeps per year for wood-burning fireplaces, once in the fall (before heating season) and once in the spring (after summer storms). Here’s why this schedule works for local homes:
- Fall sweep (September–October): This is the best time to catch early signs of animal activity before cooler weather drives them inside. It’s also when many Myrtle Beach homeowners start using their fireplaces for the first time in months, increasing the risk of nests blocking airflow. - Spring sweep (March–April): After winter, animals become more active, and summer storms can damage chimneys, creating entry points. A spring sweep ensures any nests from the off-season are removed before the humidity peaks.
Exceptions: - Gas fireplaces: If you only use a gas fireplace occasionally, an annual inspection is sufficient, but you should still check for animal signs between sweeps. - Vacation homes: These should be inspected twice a year, even if unused, because animals are more likely to nest in unoccupied chimneys. - Homes near wooded areas (e.g., Loris, Conway, or Huntington Beach State Park): These may need additional checks due to higher wildlife activity.
Pro tip: If you hear scratching between sweeps, don’t wait, schedule an emergency inspection. Many Myrtle Beach homeowners assume it’s just a squirrel, but early intervention can save hundreds in repairs. See our seasonal chimney sweep schedule for Myrtle Beach homeowners.
| Type of Animal/Nest | Cleanup Cost Range | Additional Repairs Needed? | Best Time to Schedule |
|---|---|---|---|
| Bird nest (starlings, sparrows) | $150–$350 | Sometimes (if flue is clogged) | Spring or fall |
| Raccoon nest | $300–$600 | Often (chewed liners, damaged mortar) | Immediately if active |
| Squirrel nest | $200–$450 | Occasionally (minor structural damage) | Before winter or summer storms |
| Opossum or large rodent | $400–$800 | Frequently (extensive debris, corrosion) | ASAP, health risk |
| Multiple nests (e.g., birds + raccoons) | $500–$1,000+ | Almost always | Emergency inspection |
Frequently Asked Questions
I heard scratching in my chimney last night, could it just be the wind?
Unlikely. Wind against a chimney makes a hissing or whistling sound, not rhythmic scratching. If you’re hearing deep scraping or tapping, it’s almost always an animal, raccoons, squirrels, or birds, testing the chimney for entry. In Myrtle Beach, raccoons are the most common culprits, especially in neighborhoods near marshes or overgrown lots. If the noise persists for more than a day, call a chimney sweep to inspect before the animal settles in. Learn how to identify chimney trouble signs in our Myrtle Beach troubleshooting guide.
I found feathers and twigs near my fireplace, does this mean there’s a nest inside?
Yes, feathers and twigs are definite signs of a bird nest, most likely from starlings, sparrows, or chimney swifts. These birds are common in Myrtle Beach’s coastal areas and will pack their nests tightly into flues, blocking airflow. If you also smell a musty or ammonia-like odor, the nest is likely established. Don’t wait, birds can build nests in as little as 3–5 days, and removing them later requires more work. Schedule a sweep immediately to avoid reducing your chimney’s efficiency by up to 40%. See our guide on chimney cap installation to prevent future nests.
My chimney has a cap, why are animals still getting in?
Chimney caps prevent debris and large animals, but small gaps, rusted edges, or improper installation can let in raccoons, squirrels, and birds. In Myrtle Beach’s humid climate, metal caps can corrode quickly, creating openings as small as a quarter, just enough for a starling to squeeze through. If your cap is older than 5 years, it may need replacing. Also, some caps lack fine mesh screens (1/4-inch or smaller), which are needed to block birds. A professional inspection will check for these issues and recommend repairs. Learn how to choose the right chimney cap for Myrtle Beach homes.
I think a raccoon is in my chimney, what should I do before the sweep arrives?
Stop using the fireplace immediately to avoid agitating the animal. Raccoons are nocturnal and may become more active if they sense heat or smoke. Do not try to ‘smoke them out’, this can cause a chimney fire. Instead, close the damper to limit their movement and keep pets and children away from the area. If you’re unsure whether it’s a raccoon (deep scratching, heavy thuds) or a smaller animal, take a photo or video of the chimney at night with a flashlight. This helps the sweep assess the situation faster. See our emergency chimney safety guide for Myrtle Beach.
