Garter snakes might bite when they feel threatened, are provoked, or, in rare cases, during feeding. Compared to other snake species, such as rattlesnakes or vipers, the garter snake's venom is exponentially less potent and generally poses minimal risk to humans. In fact, garter snake bites are often compared to a bee sting, causing only minor discomfort.
