In late summer, young snakes often find their way into basements. Gulf Branch Nature Center is no exception. In the past two weeks we have removed several young Ring-necked Snakes (Diadophis punctatus edwardsii) from our basement, releasing them in the surrounding forest.
Even as adults ring-necks are small snakes, typically ranging 10 – 15 inches in length. Females lay eggs in a rotting log in early summer. The young hatch and must fend for themselves. Small invertebrates make up the diet of juveniles, while older snakes will also eat earthworms, small snakes, small lizards, and salamanders. They do not bite when handled, instead releasing feces or a foul-smelling musk from anal glands. This is easily washed from one’s hands, and these small snakes can be safely and easily removed from your home.
Other common snake species with young small enough to find their way into our basements include:
These three snakes don’t initially seem to have a lot in common. Northern Brownsnakes live under rocks and logs in forests, fields and suburban areas, feeding on slugs and worms at night. They rarely exceed 15 inches in length. Eastern Gartersnakes live in a variety of habitats including forests, fields, wetlands and urban and suburban areas. Their diet is just as varied, including invertebrates, fish, frogs, salamanders, and lizards. Gartersnakes can reach lengths of 4 feet. Eastern Ratsnakes can reach lengths in excess of 6 feet. They live in fields and forests. Excellent climbers, these snakes will feed on birds and bird eggs, as well as rodents.
What these three species do have in common is that they are nonvenomous and harmless. As juveniles they may feign a strike, never actually opening their mouth, but are far more likely to try to escape than bite. They also share the unfortunate coincidence of being mistaken for juvenile Northern Copperheads (Agkistrodon contortrix mokasen). Most tales of these mistaken identities do not end well for the snake.
Copperheads are mostly uncommon in Arlington, and juveniles can be quickly identified with two simple ID tips:
The first and easiest tip is to look for bright yellow on the tail. This bright yellow tip is used by young copperheads to draw prey in closer before striking. Second, note the presence and shape of dark bands on the back of the snake. They narrow as they approach the spine, producing an hourglass or saddlebag pattern. The nonvenomous snakes shown above have patterns with spots, not bands.
If you’re uncertain about a snake you have seen, check out this webpage about Northern Copperheads from the Virginia Herpetological Society: http://www.virginiaherpetologicalsociety.com/reptiles/snakes/northern-copperhead/northern_copperhead.php. It has an excellent set of photos comparing juvenile and adult snakes to copperheads.
You are far more likely to find a nonvenomous snake in your basement. Avoid using glue traps. Snakes suffocate and suffer needlessly in them. Even if rescued from a glue trap, a snake will often have severe and irreparable damage to its scales. Gently use a broom to guide snakes into a waiting bucket or box and deposit them outside, away from your home in a grassy or wooded area.
