Hobo Spiders: Identification and Extermination

Hobo spiders, scientifically known as Tegenaria agrestis, are venomous spiders that belong to the family Agelenidae. Originating from Europe, they were accidentally introduced to North America in the 1900s and have since established themselves in several regions. Here, we delve into true and unique information about Hobo spiders, shedding light on their characteristics, behavior, and potential implications for human encounters.
Eratigena agrestis is another scientific name commonly associated with Hobo spiders. While Tegenaria agrestis is the more widely accepted scientific name, Eratigena agrestis is sometimes used as a synonym for the same species. It’s important to note that taxonomic nomenclature can vary, and different researchers or references may use different names interchangeably.



Hobo spiders, scientifically known as Eratigena agrestis, are a species of venomous spiders found in certain regions of North America. This comprehensive guide provides information on identifying hobo spiders, their behavior, and effective extermination techniques if necessary.

Hobo spiders have distinctive features that aid in their identification:

  • Body: Adult hobo spiders have a body length of approximately 8 to 14 mm. They have a light to dark brown cephalothorax and a robust abdomen with chevron-shaped markings.
  • Legs: They possess eight long, hairy legs, which are typically uniform in coloration with no distinctive banding or striping.
  • Web: Hobo spiders create funnel-shaped webs, which are usually found in low-lying vegetation, woodpiles, and crevices. These webs serve as both a retreat and a trap for prey.


Hobo spiders are nocturnal hunters that primarily reside in undisturbed outdoor habitats such as gardens, forests, and grasslands. They are ground-dwelling spiders and construct funnel webs in areas where they can ambush their prey. Hobo spiders are not aggressive but can bite if they feel threatened. Their bites may cause localized pain and discomfort.

Extermination Techniques

If hobo spider populations need to be managed, the following extermination techniques can be employed:

  1. Non-Chemical Methods:
    • Physical Removal: Use a vacuum cleaner or a broom to carefully remove hobo spiders and their webs from infested areas. Dispose of the captured spiders properly.
    • Habitat Modification: Eliminate clutter, remove piles of debris, and maintain a well-trimmed yard to discourage hobo spiders from establishing populations.
  2. Chemical Control:
    • Insecticides: In severe infestations, professional pest control services may apply insecticides to targeted areas where hobo spiders are present. It is important to follow the instructions provided by the pest control experts and take necessary precautions.
