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.

There are over 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.

Texas Rat Snake

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 of 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.

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.
