Charlotte has rattlesnakes. How to identify them & keep out of your yard

Warmer weather brings rattlesnakes out of hiding across North Carolina, including wooded areas in and around Charlotte.

Here’s what experts say residents should know about identifying the snakes, avoiding bites and what to do if one shows up in the yard:

• Two rattlesnake types live in North Carolina — the widespread timber rattlesnake (sometimes called “canebrake”) and the rare diamondback, which is mostly confined to a few federally protected lands, NC State assistant professor Skylar Hopkins told The Charlotte Observer.
• A third species, the Carolina pigmy rattlesnake, also lives in the state. All three are in decline from habitat destruction and listed on North Carolina’s Endangered Species list. Timber rattlers are the only ones likely to be spotted near Charlotte.
• Timber rattlesnakes have a distinctive pattern of dark W-shaped bands, look “fat and flat” and carry the telltale rattle on the tail, Hopkins said. A triangular head is not a reliable identifier because many nonvenomous snakes flatten their heads when threatened.
• Bites on humans are uncommon because the snakes rely on camouflage, and their venom is built for small prey like rodents, Hopkins said. If bitten, back away, photograph the snake if safe and seek medical help for swelling or hives — skip Benadryl, tourniquets and venom suction.
• A recent study by Appalachian State biology professor Matt Estep found North Carolina’s timber rattlesnake population is in “excellent genetic health, the best of any population of timber rattlesnakes that we know about right now” — a surprise given the species’ threatened status.
• To keep snakes out of your yard, reduce rodent populations, clear brush and log piles, and wear long pants and closed shoes in wooded areas — and always check the far side of a log before stepping over it, Hopkins advised.
