During the past several days, I have received several questions about silver to gray colored small snakes with dark brown blotches in backyards, garages or in the driveway. The snakes in question are juvenile black rat snakes. Juvenile black rat snakes have a distinctly different color pattern than the mostly black adult and are non venomous.
The black rat snake is commonly found in Mecklenburg County and has adapted well to the urban habitat. Like all snakes, the black rat snake is valuable to the environment because they prey on ‘pests’ and help maintain balance in the ecosystem.
Young black rat snakes when threatened will rise up, assume a coiled position and rattle its tail to scare off potential predators. This defense behavior and their unique markings often result in the snake being misidentified as a copperhead or rattlesnake.
I understand the fear many have of snakes and the surprise when a snake ends up in or near your home. My first word of advice is, if it is outside, leave it alone, it is likely moving to a safe place for shelter. If you encounter a snake and are concerned as to whether it is venomous or nonvenomous or if you want to have it moved please call Charlotte Nature Museum’s Wildlife Hotline at 704.372.6261 x603 and we will help you locate a professional.
