House spiders are common throughout North America and thrive indoors in basements, attics, and quiet corners. They build irregular, tangled webs to catch small insects and other pests. House spiders are generally non-aggressive and prefer to stay hidden, emerging only to repair webs or capture prey. They can live for over a year indoors and are considered beneficial as they help control unwanted insects.

Size: 1/4 to 1/2 inch (body length)
Color: Light to dark brown with a distinct, violin-shaped marking on its back
Habitat: Prefers dark, undisturbed areas such as basements, attics, closets, and wood piles

Brown recluse spiders are primarily found in the central and southern United States. They are known for their reclusive behavior, rarely venturing out from their secluded hiding spots. Unlike many spiders, they create irregular webs that are used more for shelter than for capturing prey. Although not aggressive, brown recluse bites can occur if they feel threatened, and their venom can cause serious skin reactions. These spiders are best identified by their unique eye pattern—six eyes arranged in pairs—as opposed to the usual eight found in other spiders.

Size: 1 1/2 to 2 inches (body length, varies by species)
Color: Brown to gray with darker markings, often resembling camouflage
Habitat: Grasslands, forests, gardens, and occasionally indoors

Wolf spiders are found throughout North America and are known for their excellent hunting skills. Unlike web-building spiders, wolf spiders are active hunters, relying on speed and agility to catch prey. They have keen eyesight, with two large central eyes that give them a distinctive appearance. Wolf spiders do not use webs to capture food but instead roam at night to find insects and other small arthropods. Female wolf spiders carry their egg sacs attached to their spinnerets and are known to carry their spiderlings on their back after they hatch. Though intimidating due to their size and speed, wolf spiders are generally harmless to humans.

Size: 1/4 to 3/8 inch (body length)
Color: Pale yellow to light green, with darker mouthparts
Habitat: Gardens, shrubs, and indoors in undisturbed areas like corners and ceilings

Yellow sac spiders are common across North America and are known for creating silk "sacs" or small tubes where they rest, often found in hidden or elevated locations. Unlike many spiders, they don’t use webs to catch prey but instead hunt actively at night, preying on insects and other small arthropods. Yellow sac spiders may bite if trapped against the skin, and while their bites can be painful and cause mild skin reactions, they are not considered medically dangerous.

Size: 1/8 to 3/4 inch (body length, varies by species)
Color: Varies widely, often with black, brown, gray, or brightly colored patterns and sometimes iridescent markings
Habitat: Gardens, shrubs, and indoors in undisturbed areas like corners and ceilings

Jumping spiders are found worldwide and are known for their remarkable jumping abilities, which they use to pounce on prey and quickly navigate their surroundings. Unlike web-building spiders, jumping spiders are active hunters with excellent eyesight provided by four large central eyes and four smaller side eyes, allowing them to track and leap accurately. Their behavior is curious and alert, often turning to observe nearby movement. Generally harmless to humans, jumping spiders are often regarded as beneficial for pest control, as they actively hunt insects and other small arthropods.
