Yellow Ratsnake
Pantherophis alleghaniensis
A large, nonvenomous climbing snake with yellow-and-brown stripes, common through much of peninsular Florida.
The Yellow Ratsnake is a color form of the Eastern Ratsnake found across much of peninsular Florida. It uses hardwood forests, hammocks, wetland edges, farms, parks, and neighborhoods where trees and prey are available.
Around buildings, ratsnakes may enter through roof gaps while following rodents or bird nests. Sealing entry points after the snake leaves and reducing rodent attractants solves the underlying conflict while preserving a valuable native predator.
Habitat:
Freshwater Wetlands, Forests and Woodlands, Urban and Residential Areas
Area / Range:
Florida Panhandle, North Florida, Central Florida, South Florida
Diet:
Kills prey by constriction and eats rodents, squirrels, birds, eggs, lizards, and frogs. Young snakes take smaller vertebrates.
Behavior:
An excellent climber, it searches trees, attics, barns, and ground cover for prey. It is nonvenomous but may coil, vibrate its tail, release musk, or bite defensively if restrained.
Daytime, Dawn and Dusk
Active Times:
Best time to see:
Warm mornings and late afternoons from spring through fall, especially near forest edges and buildings with rodent activity.
Florida Native Status:
Native
Conservation Status:
Not federally listed; generally secure, though road mortality and intentional killing affect local populations.
Safety Level:
Moderate
Safety Information:
Do not grab or corner any snake. Keep children and pets back, allow an escape route, and use a qualified wildlife professional for indoor removal. Confirm identification from a safe distance.
Benefits to Property:
Provides effective natural control of rats and mice around farms, sheds, gardens, and neighborhoods.

May enter garages, attics, sheds, or poultry areas and may take eggs or small chicks. It is often mistaken for a venomous snake.
Fun Fact:
- Young Yellow Ratsnakes look blotched rather than striped.
- They climb rough walls and trees using muscular body bends.
- The species helps limit rodents that can damage structures and food supplies.
Wildlife Laws:
Native snakes are part of Florida’s wildlife community. Avoid harming them and use lawful, humane relocation or exclusion; protected areas and certain species have additional rules. Never move a snake to another property without permission.
Identification:
Yellow Ratsnakes are slender, usually yellow to tan, with four dark longitudinal stripes and faint darker blotches between them. The belly is pale and patterned, and the head is only slightly wider than the neck. Young snakes are gray with bold brown blotches.
