Wolf Spider: Wolf Spiders are large, fast-moving hunters that are common throughout Pennsylvania. Unlike most spiders, they do not build webs to catch prey. Instead, they rely on excellent eyesight and speed to stalk and capture insects such as crickets, beetles, and other small invertebrates. Although their size and quick movements can be startling, wolf spiders are not aggressive toward people, and their venom is not considered medically significant. During the day, they take shelter in soil burrows or beneath rocks, firewood, boards, and other ground cover. As temperatures cool in fall and winter, Wolf Spiders may occasionally wander into homes, particularly basements and garages, in search of warmth or a meal. While unexpected indoor encounters can be unnerving, these spiders are beneficial predators that help keep insect populations under control.
