Range in Florida

In Florida, Gray Ratsnakes occur in the Panhandle west of the Apalachicola River. However, they do readily interbreed with Eastern Ratsnakes (Pantherophis alleghaniensis) in the area.

Assessment of risk to people and pets

Non-venomous. Gray Ratsnakes are not dangerous to people or pets, but they will readily bite to defend themselves. These snakes are not aggressive and avoid direct contact with people and pets. Virtually all bites occur when the snakes are intentionally molested.

Comparison with other species

Eastern Ratsnake (Pantherophis alleghaniensis) Non-venomous Eastern Ratsnakes in the Panhandle look like Gray Ratsnakes as both juveniles and adults. However, adults in peninsular Florida might be yellow to gray with four dark longitudinal stripes, sometimes retaining the juvenile’s dark dorsal blotches.
