Hobo Spiders in Pocatello, Idaho Falls, and Eastern Idaho
Spiders are fascinating creatures. It is amazing that something so small has the ability to create panic in people the way spiders do. While there are over 3,000 species of spiders in the United States, only Black Widows, Brown Recluses, and Hobo Spiders can cause considerable harm to humans. Brown Recluse spiders hold an almost mythical reputation of being dangerous. However, this reputation is exaggerated to an extent, and Brown Recluse spiders are not found in the Northwest. While Brown Recluse bites have been reported in the Northwest, it is commonly believed that the Hobo spider was the actual culprit of these bites. While it seems the Brown Recluse and Black Widows are known throughout the country, many people still no very little about the Hobo Spider. In this entry we will discuss this interesting creature, and many of the misconceptions associated with it.
The Hobo spider, or Tegenaria Agrestisis, is typically found in Washington, Oregon, Utah, Idaho, Wyoming, and Southwestern Canada. Originally from Europe, it is believed the Hobo spider was accidentally brought into the United States through Seattle by boat in the early to mid 1900’s. After arriving in Washington this spider has spread throughout the Northwest. They are typically 11-18 mm in body length, have solid brown legs, and few markings. These very common features make the Hobo Spider difficult to identify, and help explain why it is typically confused for Wolf or Brown Recluses. Hobo Spiders are not known climbers, but do run extremely quickly. These spiders are thought to have an aggressive temperament, and their bites can be very severe, sometimes causing necrotic lesions. (While there has been recent debate on the actual severity of the Hobo spider bite, we would rather not personally find out) Hobo spiders spin funnel shaped webs and are typically found in dark humid places and woodpiles.
Hobo spiders can become a problem in homes, as they are very protective of their nests. If you believe you have found signs of Hobo spiders in your home it is important to contact a professional to help with the problem. If you have any questions or concerns give us a call!
