Understanding Hobo Spiders

Appearance

Tegenaria agrestis are known as hobo spiders and aggressive house spiders. Because of its common features and color, they can easily be confused with other spiders.

  • Females: The hobo spider female measures between 11 to 14 mm in body length. Its brown legs are solidly colored and exhibit no markings. Females have slightly larger abdomens than males.

  • Males: The males are rarely longer than 11 mm and have a swollen appendage that appears menacing, but is merely the hobo spider’s reproductive organs.

  • Color: Hobo spiders exhibit varying hues of brown and resemble many other common spiders such as wolf spiders and brown recluse spider.

  • Characteristics: They have eight eyes clustered together, but the best characteristics to identify a hobo spider are difficult to see with the naked eye.

Behavior

Hobo spiders belong to the Family Agelenidae, a group of spiders known for their funnel-like web construction. These arachnids spin horizontal layers of entangled silk threads that serve as nests, detection devices and traps for potential prey.

Diet

Hobo spiders feed on various insects and may also consume other arachnids. Prey that comes into contact with the web triggers vibrations along the silken structure, alerting the spider. After attacking their prey, they will consume it within the narrow end of their funnel-shaped webs.

Webs

Hobo spiders weave webs in the shape of funnels that also serve as mating grounds. Females generally remain within the perimeter of their nests, while males move about in search of potential mating partners.

Reproduction

Males cautiously approach their female counterparts, mating only after finding that the female is receptive, rather than hostile. Females remain in their nests after mating. Males will either die soon afterward or move on.

Habitat

As a species of house spider, hobo spiders are most commonly found in and around human dwellings and work spaces. They inhabit lesser-used and dark areas of such places, thriving best in humid conditions. Hobo spiders may also be found beneath rocks and among woodpiles outside.

Geographic Range

Native to Europe, the aggressive house spider, or western hobo spider, was accidentally introduced to the Northwestern United States in the 1980s. They are found primarily in:

  • Colorado

  • Montana

  • Oregon

  • Pacific Northwest United States

  • Utah

  • Washington

  • Wyoming
