Snakers55, I just got a response from Alltreat (the producer of Cypress Gold). This mulch comes from the scrap wood used in making telephone poles. The wood is PINE.

Although the dye is not toxic, the Pine is, so perhaps you may want to consider using a different mulch.
I haven't used any of the Cypress Gold yet for my snakes so I will just be putting the bag on my flower garden.
