Hobo spiders can be found throughout Oregon and Washington. Several spiders including the hobo spider, make funnel webs that lead into a small space such as a hole in between bricks, shrubs or other small spaces. If you are able to safely view the underside a suspicious spider in your home remember that hobo spiders will have a light stripe running down its sternum. If it has spots rest assured it is not a Hobo spider. You’ll more likely be able to view the invader’s legs without risking contact. A hobo spider’s legs will be evenly colored. If the spider’s legs have dark rings, are shiny or dark-orange in color it is definitely not a hobo spider. Regardless of the spider species you’re dealing with, if you just want them gone Wildwoods Pest Control can effectively exterminate spiders from your house, garage, workshop and more.

Common Name: European House Spiders, Hobo Spiders, and Barn Funnel Weavers

Scientific Name: Tegenaria sp.

Family: Agelenidae (funnel web weavers)

Three species of Tegenaria funnel web spiders may be encountered around Portland-area residences. These are the barn funnel weaver (Tegenaria domestica), the giant house spider (Tegenaria gigantia), and the hobo spider (Tegenaria agrestis).

All of these spiders build funnel webs in dark, moist areas such as in woodpiles, under rocks, or in basements. Distinguishing among the three species can be difficult, and typically needs to be done with the aid of a microscope or hand lens.

Size: These spiders vary greatly in size, with the giant house spider the largest of the three species (some are large enough that, from legtip to legtip, they would spread across the entire palm of your hand!).

Behavior: Funnel web spiders sit in their sheet webs, often within the funnel portion, and wait for prey to enter their webs. The spiders that people most commonly encounter in their homes are adult males, wandering in search of females.

When and Where to Find: Males are most commonly seen during July–September when they wander in search of females. Indoors, they are most frequently found in dimly lit areas such as in boxes, closets, and storage areas.

Identification: All three of these spider species are medium brown with variably shaped lighter chevrons on the dorsal (upper) side of the abdomen. These species of funnel weaver spiders cannot readily be distinguished with the naked eye and require examination under magnification.
