Rattlesnakes in Arizona: Everything You Need to Know
Introduction
Rattlesnakes are a common sight in the southwestern United States, including in Chandler, Arizona. Known for their distinctive rattling sound and venomous bites, these snakes can be a cause for concern for residents and visitors alike. In this article, we will answer some common questions about rattlesnakes, their behavior, habitat, and protection in Arizona.
Are Rattlesnakes Poisonous or Venomous?
One of the most common questions people have about rattlesnakes is whether they are poisonous or venomous. The answer is that they are venomous. Poisonous animals deliver toxins through ingestion, while venomous animals deliver toxins through bites or stings. Rattlesnakes, like all pit vipers, are venomous, delivering their venom through specialized fangs.
When Do Rattlesnakes Come Out?
Rattlesnakes are cold-blooded reptiles and are most active in warm weather. In Arizona, they can come out of hibernation as early as February or March and can be active until October or November, depending on the weather. They are most active during the early morning and late afternoon when temperatures are cooler.
How Do Rattlesnakes Rattle?
Rattlesnakes produce their distinctive rattling sound by vibrating their tail. The sound is created by the rattles on the end of the tail, which are made of keratin, the same material as human hair and nails. As the snake vibrates its tail, the segments of the rattle knock against each other, creating the distinctive sound.
What Do Rattlesnakes Eat?
Rattlesnakes are carnivorous and eat a variety of prey, including rodents, lizards, birds, and other snakes. They are ambush predators, waiting for their prey to come within striking distance before they attack. They have specialized venom that helps them immobilize their prey and begin the digestion process.
Are Rattlesnakes Deadly?
Rattlesnakes can be deadly if their bite is not treated promptly. Their venom can cause a range of symptoms, from swelling and pain to respiratory distress and even death. However, most bites are not fatal, and with prompt medical treatment, the chances of survival are high.
Are Rattlesnakes Nocturnal?
While some species of rattlesnakes are nocturnal, many are active during the day. In Arizona, rattlesnakes are most active during the early morning and late afternoon when temperatures are cooler. They may also be active at night during the hottest months of the year.
How Often Do Rattlesnakes Shed?
Rattlesnakes shed their skin several times a year, with young snakes shedding more frequently than adults. The frequency of shedding depends on factors such as growth rate, diet, and temperature. In general, adult rattlesnakes shed their skin two to four times a year.
How Do Rattlesnakes Mate?
Rattlesnakes mate in the spring, shortly after emerging from hibernation. The male will locate a female using his sense of smell and will engage in courtship behaviors, such as bobbing his head and flicking his tongue. If the female is receptive, the two will mate, and the female will give birth to live young several months later.
Where Do Rattlesnakes Go in the Winter?
In colder months, rattlesnakes enter a period of dormancy known as hibernation. They will seek out areas with stable temperatures and high humidity, such as underground burrows or rock crevices. In Arizona, rattlesnakes may begin hibernation as early as October or November and emerge as early as February or March.
Where Do Rattlesnakes Live? Map of Habitat
Rattlesnakes are found throughout much of the southwestern United States, including in Arizona. They prefer arid environments such as deserts, grasslands, and rocky outcroppings. Here’s a map of the areas in Arizona where rattlesnakes are commonly found:

Are Rattlesnakes Protected in Arizona?
In Arizona, all native species of rattlesnakes are protected under state law. It is illegal to kill, harass, or collect rattlesnakes without a permit. The Arizona Game and Fish Department manages permits for the collection and relocation of rattlesnakes.
How Often Do Rattlesnakes Eat?
Rattlesnakes can go for weeks or even months without eating, depending on factors such as temperature and activity level. They have a slow metabolism and are able to conserve energy by slowing down their bodily processes. When they do eat, they can consume prey that is up to 75% of their own body weight.
Are Rattlesnakes Born Live?
Yes, rattlesnakes are ovoviviparous, which means they give birth to live young. The female carries her young inside her body until they are fully developed, then gives birth to a litter of 3-14 snakes. The young are born fully formed and are able to fend for themselves soon after birth.
Will Rattlesnakes Chase You?
Contrary to popular belief, rattlesnakes do not chase humans. They are generally shy and prefer to avoid confrontation. If they feel threatened, they may rattle their tails as a warning, but they will only strike as a last resort. It’s important to give rattlesnakes plenty of space and to avoid approaching or handling them.
How Many Rattlesnakes Are in Arizona?
It’s difficult to estimate the exact number of rattlesnakes in Arizona, as populations can fluctuate depending on a variety of factors. However, it’s safe to say that there are many thousands of rattlesnakes in the state. Arizona is home to more than a dozen species of rattlesnakes, including the Western Diamondback, the Sidewinder, and the Mojave Rattlesnake.
How Often Do Rattlesnakes Shed Their Skin?

How Do Rattlesnakes Get Their Rattles?
Rattlesnakes are born with a small button at the end of their tail, which they use to create a rattling sound by vibrating their tail. As the snake grows and sheds its skin, additional segments are added to the button, creating the rattles.
Why Do Rattlesnakes Rattle?
Rattlesnakes use their rattles as a warning to potential predators or threats. When they feel threatened, they will rattle their tails as a way to signal their presence and to warn the threat to stay away. The sound of the rattle can be heard from a considerable distance, and it serves as an effective defense mechanism for the snake.
How Many Rattlesnakes Are Born at a Time?
The number of offspring produced by a female rattlesnake varies depending on the species and the size of the female. On average, a female may give birth to a litter of 3-14 young at a time. Some species, such as the Western Diamondback, can produce litters of up to 25 offspring.

How Do Rattlesnakes Survive in the Desert?
Rattlesnakes are well adapted to survive in the harsh desert environment. They are able to conserve water by minimizing their metabolic processes and can go for long periods without drinking. They also have specialized venom that helps them immobilize their prey, which may be scarce in arid environments.
Why Might Rattlesnakes Not Rattle?
While rattlesnakes are known for their distinctive rattling sound, there are some situations in which they may not rattle. If they feel threatened and believe that remaining still is the best course of action, they may not rattle. Additionally, some rattlesnakes may have lost their rattles due to shedding or damage.
How Many Rattlesnakes Live in a Den?
Rattlesnakes often den together in groups, especially during the winter months. The number of snakes in a den can vary widely depending on factors such as the size of the den and the availability of food and water. Some dens may contain only a few snakes, while others may have dozens or even hundreds.
