5 Common Spiders in Boise: Identification and Control Tips

In Boise, we share our environment with a variety of spider species. While spiders play a crucial role in our ecosystem, it's important to know which ones are common in our homes and gardens, and how to manage them effectively. Today, we'll introduce you to the five most frequently encountered spiders in Boise and provide expert advice for their control.


1. The House Spider (Parasteatoda tepidariorum)

  • Identification: This familiar spider is typically grey or brown, with a round abdomen, and is about a quarter-inch in size. They're often found in less-traveled corners of our homes.
  • Control Tips: Regular cleaning, reducing clutter, and sealing gaps around doors and windows are effective ways to deter these spiders. They're harmless but can be a nuisance due to their webbing.


2. The Bold Jumping Spider (Phidippus audax)

  • Identification: Recognizable by its stout body, short legs, and distinctive jumping behavior, this spider has a black body with white or yellow markings.
  • Control Tips: Jumping spiders are predominantly outdoor dwellers. Maintaining a tidy garden and installing window screens can minimize their presence indoors.


3. The Yellow Sac Spider (Cheiracanthium inclusum)

  • Identification: These small, pale yellow spiders measure about 1/4 to 3/8 inches long. They're commonly seen in gardens or on exterior walls.
  • Control Tips: To keep these spiders outside, seal cracks and crevices in your home's exterior. Regular pest control treatments are also effective in controlling their numbers.


4. The Western Black Widow (Latrodectus hesperus)

  • Identification: Easily identified by the red hourglass marking on its underside, the black widow spider is glossy black and measures about 1.5 inches across.
  • Control Tips: Black widows favor secluded areas like garages or sheds. Exercise caution in these spaces, especially when moving long-stored items. For safety, professional pest control services are recommended for dealing with black widow spiders.


5. The Hobo Spider (Eratigena agrestis)

  • Identification: This spider is brown with a body length of about 1/2 inch. While often mistaken for the more dangerous brown recluse, hobo spiders are less threatening.
  • Control Tips: Preventing entry is key with hobo spiders. Ensure that your home’s ground-level openings are sealed, keep areas around the foundation clear, and maintain window screens in good repair.


Understanding these common spiders in Boise is the first step in managing them effectively. While most spiders pose little threat and contribute positively to controlling insect populations, it's natural to prefer keeping them at a respectful distance from our living spaces.
