All rattlesnakes have large triangular heads and, of course, a rattle at the end of their tails. Because there are 32 species, they will vary in size and color depending on the part of North America they’re in. In general, they are light gray, brown, or olive with a distinct diamond pattern. Their rattle can be hard to see unless you are close to the snake, so it’s not the best feature to use to identify them.

The highest concentration of rattlesnakes is in the southwestern U.S., but their habitat extends to much of North America and even in South America. While they’re most commonly associated with arid desert habitats, rattlesnakes can also be found in woodlands and swamps because of their wide range.

Like most vipers, rattlesnakes have medically significant venom that causes swelling and tissue damage, which can result in death. If bitten by a rattlesnake, receiving immediate medical attention is crucial. They are the most venomous snakes in North America and when not treated, their venom causes more damage over time. Luckily, anti-venom is commonly accessible in areas with large rattlesnake populations.

The best way to prevent snakes is by reducing their food sources in your area. This means removing piles of debris and trash from your yard where both rodents and snakes can hide. Using non-toxic snake repellant will encourage them to leave your yard. If you see a rattlesnake near your house, call Hughes Exterminators for professional snake control and removal. Attempting to remove one yourself is not worth risking a bite from these dangerous snakes.
