Cottonmouth

Cottonmouths are venomous snakes with thick bodies, reaching lengths of 30-48 inches. Key identifiers include a dark brown or black coloration (though juveniles can be lighter with dark crossbands), a triangular head, and a white, cotton-like lining of the mouth displayed when threatened. They have elliptical pupils and a heat-sensing pit between the eye and nostril on each side of the head.

Cottonmouths are not typically found *inside* homes, but may be present in yards, especially near water sources. Look for them near ponds, ditches, swamps, and slow-moving creeks. You may see them basking on logs or rocks, or swimming in the water.

MBPC does not directly handle snake removal, as it falls outside the scope of SC Department of Pesticide Regulation. However, we can offer advice on habitat modification to deter snakes and recommend licensed wildlife removal specialists operating in the Grand Strand area. Reducing potential food sources, like rodents, can also help.

Clear dense vegetation and debris around your property to reduce potential hiding spots. Avoid approaching or handling any snakes you encounter. Keep pets on a leash when walking near water sources in Myrtle Beach, and teach children to respect wildlife and maintain a safe distance.

Cottonmouths thrive in the humid subtropical climate and coastal habitats of Myrtle Beach. They are commonly found near freshwater sources like swamps, marshes, rivers, and creeks. These snakes often inhabit areas with dense vegetation and readily available prey, making them relatively common along the Grand Strand.
