Brown widow spiders are usually harmless to home and people as they try to avoid human activity.

  • They can be tan to dark brown in color, but also gray and even almost black
  • Orange to yellowish, prominent, hourglass figure on its abdomen
  • Black marks at the top end of the 3 diagonal abdominal stripes are large and square-shaped
  • Venomous, but injects less venom into their prey so they are not dangerous to humans


  • Reduce clutter
  • Regularly vacuum or sweep corners of rooms, storage areas, basements, windows, and other seldom-used areas to remove spiders and their webs
  • Use closed or zip-lock bags and boxes when storing items in basements or garages
  • Make sure windows and doors are tightly closed
  • Fix any cracks, crevices or holes that may allow spiders to enter
  • Outside the home, potential hiding places such as building materials, firewood, and other debris lying on the ground should be moved away from the building or disposed of


  • Brown widow bites are not as severe as black widow bites
  • Clean the bitten area with soap and water
  • Apply an ice pack to the affected area to numb the pain and swelling
  • If there are any severe symptoms besides slight pain, itching, swelling, and redness that persists, contact your doctor
