How Are Snakes Born? The life cycle of a snake largely varies by species. Some snakes lay eggs, while others give birth to live young in broods ranging from one or two newborns to litters of nearly 100. In some rare species, snakes lay eggs without mating in a process known as parthenogenesis. Snakes born from eggs, like the common green snake or corn snake, emerge using special teeth used to break the leathery membranes of their shell casings. Newly hatched snakes, also called snakelets, must feed in order to survive and usually find small rodents or reptiles for sustenance. How Long Do Snakes Live? Snakes reach sexual maturity within two to four years, depending on the species and living conditions. In perfect conditions, adult snakes live anywhere from 20 to 30 years, with natural predators and the encroachment of humans severely limiting the number of years most snakes live. Detection & Removal Because newborn and juvenile snakes molt as they grow, the discovery of molted snake skins may indicate that the reptilian pests are living and breeding nearby. The presence of snake eggs, both hatched and unhatched, or the sight of snakes at any stage of the life cycle is also indicative of a snake problem. For safe and effective snake removal, contacting the professional wildlife control specialists at Critter Control is the best plan of action when snake infestations become apparent.
