Can you use a standard humidifier to humidify a snake enclosure?

Most snakes don't need a humidifier. The vast majority of the commonly-kept species thrive in relatively dry, temperate climatesThe only species that need high humidity - are those found in rain-forests. Commonly-kept species - such as those from northern america, (corn snakes and garter snakes) don't need high humidity. Neither do those from Africa/Asia such as Royal & Burmese pythons. Even Boas from Central America don't need the humidity that high.

In most cases, gently misting the vivarium a couple of times a week, using a simple spray-bottle filled with water - is sufficient to raise the humidity if needed.
