Snakes near Dallas are most active during the spring, summer, and early fall months. During the cold winter season, most go into a state of brumation. Brumation is the cold-blooded equivalent of hibernation, in which the snake’s metabolism slows, and they become stuporous and slow. 

Snakes near Dallas are most active in the daytime when temperatures reach about 65 degrees. They come out to warm their bodies, and to hunt. As the summer turns hot, they become more crepuscular (active at dawn and dusk), and even nocturnal, to avoid the intense heat. So, if you’re watching out for snakes, keep the temperature and time of year in mind.

Non-Venomous Snakes Near Dallas

An overview of 7 Snakes Near Dallas in North Texas.

There are more than 30 species of snakes near Dallas. Out of those, only a few are venomous. The most common snakes you might see in the area, by far, are Texas rat snakes, western ribbon snakes, and Texas brown snakes. If you see a snake in the water, chances are very good that it’s either a diamondback water snake or a blotched water snake, both of which are non-venomous.

Let’s take a closer look at the three most common non-venomous snakes near Dallas.

The most common snake near Dallas is the Texas rat snake. This snake is tan with olive green or brown blotches. It can reach lengths over five feet long, and prey primarily on rodents.

Unfortunately, despite their non-aggressive nature, they’re often killed by fearful humans who mistake them for venomous snakes. In fact, Texas rat snakes are essential for rodent control, and can be found anywhere there is a large rodent population.

Western Ribbon Snake

Western ribbon snakes are small, slender snakes native to North Texas. They grow to a maximum length of around four feet and eat mostly earthworms. They’re easy to recognize by the black and yellow stripes that run from head to tail. These snakes are easygoing and very unlikely to bite humans. 

Texas Brown Snake

They have light brown bodies with regular dark brown markings and a dark brown head. Like the western ribbon snake, they’re very gentle and pose no threat to humans.

Texas coral snakes are not one of the most common snakes near Dallas. They’re characterized by alternating bands of red, black, and yellow stripes and can grow up to four feet long. These venomous snakes are very shy and tend to come out mostly at night, so your chances of encountering one are slim.

Cottonmouth (Water Moccasin)

These snakes near Dallas are most likely to be encountered in or near a source of water. They’re dull brown, with irregular light and dark stripes, and can grow up to five feet long. Cottonmouths have a highly venomous bite and are known to stand their ground when threatened, rather than fleeing. If you encounter a cottonmouth in the wild, it’s always best to let it be.

Western Diamondback Rattlesnake

Western diamondback rattlesnakes are most likely to be seen in hot, dry areas with plenty of brush or rocky outcroppings. They can grow up to five feet long, and come equipped with the famous rattle. They eat mostly rodents and only bite when threatened. As with the other species of venomous snakes near Dallas, it’s best to leave these impressive creatures alone.

There are several subspecies of copperhead around Dallas. These include the southern copperhead in East Dallas and the broad-banded copperhead in West Dallas. Copperheads grow to around three feet long and can deliver a painful, venom-filled bite. Most bites to humans occur either when the snake is accidentally stepped on, or when people try to handle or kill them. If you encounter a copperhead, remember that it’s a dangerous wild animal, and should not be approached or touched.
