Spider Bites

Spider bites are a real concern for parents of young children and families that keep pets.

Venomous spiders, in general, will typically not bite you unless they feel threatened or provoked. Most spider bites are not considered to be harmful to humans. 

Very few spider bites result in victims requiring urgent medical attention or treatment. However, North America does have a couple of spiders that can cause some real harm to animals and humans if bitten.

Spider Bite Symptoms & Treatment

Most spider bites will have little effect on people but some species can cause a reaction due to the venom injected.

Most spider bites go unnoticed and cause no more than a mild reaction in people like inflammation of the skin, minor swelling and itching. Some spider bites however can lead to lots of pain, gangrene and even necrotic wounds.

Spider Bites in the United States

Black Widow Spider

Black Widow Spiders

Adult Black Widow spiders are not naturally aggressive towards people.

  • They only bite as a defensive measure if they feel threatened.
  • Most defensive bites to people occur when the spider is unintentionally squeezed or pinched.
  • Bites may result in localized pain, tingling and small swelling around the bite.
  • Occasionally more serious symptoms can occur but are usually an exceptional reaction of the individual to the spider’s venom.

Brown Recluse Spider

Brown Recluse Spider Listing

They only bite when crushed, handled or disturbed. Both sexes are venomous.

  • Reactions to bites will vary - some people are unaffected, others may feel a pinprick, others a stinging sensation followed by intense pain.
  • Some people may not be aware of the bite for 2 to 8 hours.

Hobo Spider

Hobo Spider

Although not proven, it is suggested that the bite of adult hobo spiders can have similar effects of brown recluse spider bites. 

  • Hobo spiders can be found in places that have cracks and crevices where they can hide. 
  • Hobo spiders are poor climbers and most commonly found in basements and cellars. 
  • Male hobo spiders are responsible for more bites as they wander into buildings during their early-autumn mating season. 
  • Circumstantial evidence suggests the bite of male hobo spiders is more toxic than females. 
  • Hobo spiders are most commonly encountered in Northwestern states in the U.S. but is rapidly expanding its range in recent years.


In addition to potentially dangerous spiders, there are many commonly encountered spider species whose bite are not considered medically important. Spiders with non-serious bites in the U.S. include house spiders, cellar spiders, daddy long legs, wolf spiders and many more.
