The two most dangerous spiders that call the Great Lakes area home are the brown recluse and the northern black widow. The Great Lakes area is also home to many orb-weaver spiders, which make the typical spiral-shaped webs you find in your garden. The common house spider is also prevalent, as well as several spiders who spend much of their time near water, where the insects that make up their diet are plentiful. The striped fishing spider and the six-spotted fishing spiders also thrive by the lakes.
