Snake seen near the foundation, garage, or crawl space access
Snakes enter structures in pursuit of rodents or seeking shelter. A snake in the crawl space often indicates a rodent population that attracted it.
Six Venomous Species in Coastal South Carolina
Snake Removal in Mount Pleasant, SC
Active March through November; most encounters April through September
The gist
South Carolina has six venomous snake species: copperhead, cottonmouth (water moccasin), eastern diamondback rattlesnake, timber rattlesnake, eastern coral snake, and pygmy rattlesnake. Coastal Charleston County is within the range of all six. Non-venomous snakes — rat snakes, black racers, kingsnakes, and corn snakes — are beneficial and protected. All snakes in South Carolina are protected by state law.
What to look for
Spotting it
What normally prompts the call.
Shed skin found in the attic, crawl space, or garage
A snake has been using the area as shelter. Shed skin length indicates the size of the snake.
A coiled snake near a water feature, pond, or drainage ditch
Cottonmouths and other water snakes are common near the waterway edges and ornamental ponds throughout Mount Pleasant.
Why this is a coastal SC problem
The Lowcountry's salt marshes, tidal rivers, ponds, and wooded areas provide ideal habitat for a wide diversity of snake species. Mount Pleasant's proximity to coastal wetlands means cottonmouths and diamondbacks are within range of residential areas.
Snakes follow rodent populations. A home with an active rodent problem may attract rat snakes and racers, which are effective natural rodent predators.
Marsh-fringed lots near tidal creeks give snakes plenty of cover, and that pattern holds beyond Mount Pleasant too. The licensed pros we connect you with report similar calls near the Ashley River and around tidal marsh creeks closer to Charleston, where damp ground and brush pull snakes in behind the rodents they hunt. Out toward James Island, the same overgrown ditches and drainage edges along the Folly Road corridor set up the exact conditions that bring a snake onto a porch or into a garage without much warning.
This comes up across Mount Pleasant and the surrounding towns, I'On, Dunes West and Awendaw included.

Commonly confused with
Non-venomous water snakes vs. cottonmouth. Banded water snakes and cottonmouths are frequently confused. Cottonmouths have a chunky body, wide triangular head, and show the white mouth interior when threatened. Water snakes are slender with a narrower head and flee rather than stand their ground. If unsure, treat it as venomous and maintain distance.
The treatment, step by step
Live capture and relocation of snakes inside structures
Exclusion of entry points to prevent re-entry
Rodent control to eliminate the food source that attracts snakes
Vegetation management — reducing dense ground cover and debris piles adjacent to the structure
The honest split is simple: contained and caught early is a single visit; recurring outdoor pressure is a plan.
| What you have | The sensible answer |
|---|---|
| A single active problem, found early | Single visit |
| Something that keeps reappearing | Recurring plan |
| A problem in wall voids, an attic or a crawl space | Treatment, then closing the way in |
The regulatory side
All snakes in South Carolina are protected by state law. Non-venomous snakes cannot be killed. Venomous snakes that pose an immediate threat may be dealt with by a licensed professional. SC DNR can be contacted for guidance on specific species encounters.
The damage and the clean-up
Snakes themselves cause minimal structural damage. Their presence inside a structure is alarming and their feces can stain. The primary damage concern is the rodent infestation that attracted them.
The homeowner side of it
Non-venomous snakes can be encouraged to leave on their own by removing shelter (debris piles, wood stacks, dense ground cover). Do not attempt to handle or kill any snake — all snakes are legally protected in South Carolina, and misidentification is dangerous. Contact a licensed wildlife control operator for removal from inside a structure.
The health side, honestly
Venomous snake bites are a medical emergency. Seek emergency care immediately for any suspected venomous snake bite. Do not apply a tourniquet, cut the bite, or attempt to suck out venom. Immobilize the bitten limb below heart level and transport to the nearest emergency room.
Putting a number on it
A guide figure for snakes locally is an estimated $189 to $549, which is a band rather than a quote. The inspection costs nothing and the real number goes in writing before anyone starts. Estimated bands, and what pushes a job up or down them, are set out on the pricing guide, and the service that handles this is Wildlife Removal.

Questions & Answers
Frequently Asked Questions
Is a cottonmouth really that dangerous?
Yes. Cottonmouths (water moccasins) are pit vipers with potent hemotoxic venom and are not shy about standing their ground when encountered. They are common near any water feature, pond, or drainage area in the Lowcountry. Treat any thick-bodied snake near water as potentially venomous and maintain distance.
A rat snake got in my attic. What do I do?
Rat snakes are non-venomous, beneficial, and common in the Lowcountry. They enter attics following rodents. Contact a wildlife control operator for live removal. The long-term solution is sealing the entry point and addressing any rodent issue.
Can I kill a snake in my yard?
No. All snakes are protected in South Carolina. Killing a non-venomous snake is a state wildlife violation. Contact a licensed wildlife control operator for removal from inside a structure, and leave snakes in the yard alone or contact SC DNR for guidance.
