The rosy boa spends most of its life concealed beneath rocks and in crevices to escape the elements and natural predators.
 Granite outcroppings are the most common geologic association inhabited by the rosy boa.
Less often, it is found in association with volcanic or other rock types.
Only in rare places does the rosy boa inhabit rockless environments.
In areas with few rocks, the rosy boa uses rodent burrows for concealment.

The rosy boa's activity season follows local weather patterns; however, it is generally dormant during the winter, and active during the spring, summer, and fall.
Like all snakes, it is dependent on external temperatures to promote such normal bodily functions as digestion and gestation.
Throughout most of its range, the winter is too cold for these functions and the rosy boa goes into a dormant state called brumation.
The spring is breeding season, resulting in its highest rate of activity.
Most specimens of the rosy boa are encountered in spring as they leave the security of their rock piles and crevices to seek mates.
Another reason why the rosy boa may be active on the surface of the ground is to find prey or new territory.

The surface activity of the rosy boa can take place during any hour of the day, but during hot weather, it is primarily nocturnal.
In the spring, it is often out in the afternoon and early evening.
In the late spring and summer, this activity period switches from dusk to late into the night.
Because most populations of the rosy boa live in exceedingly dry habitats, activity is often highly moisture-dependent.
During dry periods it remains deep underground to assist in remaining hydrated.
Recent rainfall often results in a flurry of surface activity.

The rosy boa forages mainly for small mammals, but has occasionally been known to take other prey items, such as lizards, birds, and mammals.
Pack rats, baby rabbits, deer mice, and kangaroo rats make up a large portion of its diet.
The rosy boa is one of the slowest-moving species of snakes in the world.
It is unable to pursue prey and must either wait in ambush or stalk its meals.
When a meal is within reach, usually a few inches, a rosy boa strikes with surprising speed and accuracy.
Prey is secured with tiny rows of needle-sharp teeth, then suffocated through constriction.

The rosy boa is extremely docile when encountered by humans.
When disturbed, it usually rolls into a compact ball with the head in the center.
The species is not prone to bite in defense, but rather will release a foul-smelling musk from the base of the tail when threatened.
When human bites have occurred, they have usually been the result of a feeding response with a captive animal.
The rosy boa is nonvenomous.
Its extreme docility, few needs, and attractive coloration have made the rosy boa popular with herpetoculturists.
