The Sinaloan milksnake rests during the day under rocks, in rock crevices or beneath cactus plants. It can also be found on farmland under woodpiles and in old buildings. They are non-venomous and harmless to humans. Some milk snakes have a striking resemblance to coral snakes and this mimicry likely scares away potential predators.

While both milk snakes and coral snakes possess transverse bands of red, black and yellow, a common mnemonic can be used to properly distinguish between the deadly coral snake and the harmless milk snake: "Red on yellow will kill a fellow, but red on black is a friend of Jack."
