Facts About Spiders

Characteristics
  • Spiders have four pairs of legs, eight in total
  • Most spiders have six to eight simple eyes in various arrangements 
  • All spiders have a pair of jaw-like structures, the chelicerae, each of which ends in a hollow fang through which venom can be injected 
  • Spiders have two body regions
    • Cephalothorax - fused head and thorax
    • Abdomen
    • They're joined by a narrow waist 
  • The tip of the abdomen has a group of fingerlike spinnerets to produce silk
Spider Bites
  • Only two species of spiders are dangerous to humans
    • The brown recluse spider
    • The black widow 
  • The sac spider species (clubionids) are suspect for most spider bites
    • Their venom is cytotoxic
    • It causes tissue around the bite to die 
  • The vast majority of spiders are harmless to humans 
  • Usually, there is no more than a slight swelling of the bitten area
  • Most spiders fangs are too small or weak to puncture human skin 
  • Spiders don't bite unless they are pressed or held against the skin
  • Some will actively protect their egg sacs and young
Habitat
  • Some like damp places:
    • Basements
    • Crawl spaces
    • Damp parts of buildings 
  • Others like dry, warm areas:
    • Subfloor air vents
    • Upper corners of rooms
    • Attics 
  • They will hide in dark areas
Diet
  • Spiders are predators and feed on living prey, mostly other insects 
  • They produce a venom that is poisonous to their normal prey
  • Venom is injected through the hollow fangs
  • Venom immobilizes the prey and begins the digestion process
  • Then they suck the digested liquid food 
  • Some species build webs to trap prey, other spiders actively hunt 
  • Passive hunters lie in wait for prey rather hunting
Reproduction
  • Spiders produce egg sacs which are laid either in a web, attached to a surface, or carried in the female 
  • Spiders may produce several egg sacs, containing several hundred eggs 
  • Spiders grow by molting or shedding its skin multiple times before reaching maturity 
  • In many species, males wander in search of a mate 
  • Some species live for many years, but most only live for one season
Sanitation is the best control and preventative measure.
