Characteristics of Spiders:
Spiders have eight legs, two body regions, and no wings or antennas. They have three or four pair of eyes.
Habits and Lifestyle:
The lifestyle can vary between spiders. Some spiders like to live in damp conditions such as basements, and crawl spaces. Other spiders prefer to live in dry, warm areas such as air vents, upper corners of rooms and attics and hide in dark areas.
Spiders feed on insects, other spiders, and any other prey they can subdue.
Spiders produce silk that is elastic and strong. Their silk is used to spin webs where they can live and keep their egg sacs. Each web's size and shape is varied according to the spider. Some webs are orb-shaped, while others are funnel-shaped, orderly, haphazard, etc. Some spider species live in burrows instead of webs, while others live in crevices.
Almost all spiders are venomous, but the black widow, brown recluse, hobo, and yellow sac spiders are the most venomous spiders in the United States.
Black Widow Spiders: Characterized by the hourglass marking on its belly. The bite feels like a pinprick. Signs and symptoms of the bite can include: swelling, faint red marks, intense pain and stiffness, severe abdominal pain or cramping, excessive sweating.
-Webs commonly found near ground level, irregular shape, uneven and tangled
Brown Recluse Spiders: Characterized by a violin-shaped marking on its back, which can be difficult to see. Signs and symptoms of the bite can include: at first a mild stinging, redness and intense pain within 8 hours, a deep blue or purple area around the bite (which may develop a red ring around it)
-Webs commonly found in storage boxes, shoes, clothing, tires, beneath furniture; the web is loose, sticky, and off-white or grayish;
Hobo Spiders: Even though the bite of a Hobo Spider is initially painless, it can be serious. A redness will first appear around the bite site, which will develop into a blister after 24 hours, before breaking open, leaving an open, oozing ulceration. The bite might also cause severe headaches lasting 2 to 7 days and even nausea, weakness, fatigue, malaise, temporary memory loss and vision impairment.
-Webs are funnel-like shaped
Yellow Sac Spiders: This species has a mildly toxic venom. Bites can be painful and cause skin irritations: erythema, edema and pruritis. Yet, though wounds may become slightly necrotic, they usually heal in rather rapidly without severe scarring.
-Create a sac instead of a web, and prefer a corner usually near the ceiling
Signs of Infestation:

Spider eggs are in a silken sac, which may be fixed on a surface, hidden in the web or carried by the female
