Common Spiders

Latin Name: Arachnida

Common House Spiders

  • Appearance: Common house spiders typically have brown or gray coloration with a bulbous abdomen. They are usually small to medium-sized.
  • Behavior: They are harmless to humans and primarily feed on other small insects. You'll often find their messy, irregular webs in corners or other secluded areas indoors.
  • Habitat: These spiders are highly adaptable and can live in many areas of the home, particularly in basements, attics, closets, and garages.
  • Risk to Humans: Although their presence can be unsettling, these spiders are not aggressive and rarely bite. If they do bite, it's usually because they feel threatened, and their venom is not harmful to humans.
  • Cellar Spiders (Daddy Longlegs)

  • Appearance: Cellar spiders, often called "daddy longlegs," have extremely long, thin legs relative to their small bodies. They are usually pale brown or gray.
  • Behavior: Cellar spiders are known for their delicate, loosely constructed webs, often found in undisturbed areas. They can vibrate in place as a defensive behavior when threatened, which gives them a blurry appearance.
  • Habitat: They favor dark, damp environments like basements, cellars, and crawl spaces, but they may also be found in other quiet, indoor areas.
  • Risk to Humans: Contrary to myths, cellar spiders are harmless to humans. Their venom is not dangerous, and they pose no threat, often feeding on smaller insects and even other spiders.
  • Triangulate House Spiders

  • Appearance: Triangulate house spiders are light yellowish-brown with a distinctive pattern on their abdomen, typically consisting of dark, triangular or V-shaped markings. They're small to medium-sized.
  • Behavior: These spiders are non-aggressive and tend to stay in one spot, building small, sheet-like webs in low-traffic areas of homes.
  • Habitat: They prefer dry, undisturbed indoor spaces and are often found in closets, behind furniture, and in garages.
  • Risk to Humans: Like other house spiders, they are not harmful to humans and rarely bite. They are generally beneficial, as they help control the population of other insects inside homes.

    Woodlouse Spiders

    • Appearance: Adults are about 1-2 cm in length and have a reddish-brown cephalothorax, creamy-colored abdomen, and bright orange or red legs.
    • Behavior: Woodlouse spiders are nocturnal and are active hunters rather than web builders. And despite their fearsome appearance, they are generally non-aggressive toward humans.
    • Habitat: These spiders are often found in moist, dark environments where their prey, woodlice (commonly called pill bugs or roly-polies), thrive.
    • Risk to Humans: Although their presence can be unsettling, these spiders are not aggressive and rarely bite.
