Since snakes are adaptable to multiple climates and regions, they can be categorized as ground-dwelling or arboreal and as venomous or non-venomous. Arboreal, or tree, snakes are generally more active and smaller than their ground-dwelling counterparts, which are heavy-bodied and sedentary. Due to the irregular feeding patterns and infrequent defecation of both varieties, finding snake droppings is rarely the easiest way to confirm an infestation. Still, homeowners with snake problems may find some waste left by these pests.
