Garter snakes occupy a variety of habitats including pond and stream edges, wetlands, forests, fields, rocky hillsides and residential areas. They are often observed as they bask on rocks, woodpiles, stonewalls, hedges and swimming pool decks.
Although they feed on a variety of small animals, garter snakes’ primary prey are earthworms and amphibians. Their saliva appears to be toxic to amphibians and other small animals.
Occasionally, garter snakes make their way into basements, a situation that appears to be most common in spring or autumn.
Garter snakes are completely harmless and quite gentle, however, they do not make good pets.
