Habits of Brown Recluse Spiders:

Brown Recluse Spider

  • Females produce from one to five egg sacs, each containing 40 to 50 eggs.
  • Developmental time (egg to adult): approximately 336 days.
  • Life span of females: averages 628 days.
  • They construct a nondescript, irregular web used almost exclusively as a retreat.
  • The nest typically is built in secluded locations, e.g., among old papers, in seldom-used clothes and shoes, and in attics.
  • Outdoors, they typically are found under rocks and in barns and sheds.
  • When hunting, they usually retreat to their nests whenever they are disturbed.

Damage Caused by Brown Recluse Spiders:

  • Brown recluse spiders inflict a painful bite that may develop into an ugly, slow-healing ulcer.

Look for:

  • Dark protected areas which attract insect prey.
  • Nondescript webbing.

How to Control and Kill Brown Recluse Spiders:

  • Clutter and debris inside structures and scrap lumber, woodpiles, rocks and other protective outdoor materials should be removed.
  • A vacuum cleaner should be used to remove spiders, webs, and egg sacs and the bag immediately sealed and discarded.
  • Outdoor lighting that attracts insects to the structure should be changed.
