Hobo Spiders

Date: August 20, 2007 / Posted by: Admin AH / Pest Alerts

Hobo Spiders are found in the Pacific Northwest region of the United States. They prefer woodpiles, hollow stumps, trash piles, sheds and garages. They are sometimes found inside homes in cluttered areas such as basements and crawl spaces.

Hobo Spiders are brownish in color and measure about 1/2 to 2/3 inches long. Their legs have short hairs and their abdomens have several chevron-shaped markings. They are also known as the “aggressive house spider”. I don't know about you, but I don't want any spiders in my house, especially not aggressive ones! Actually, they will avoid contact with humans, but will bite when accidentally squeezed or crushed. Hobo Spider bites can be very serious. It isn't usually painful at first, but within 24-36 hours the bite turns into an oozing sore. The most common symptom is severe headaches, but nausea, weakness, fatigue, temporary memory loss and vision impairment have also been associated with the Hobo Spider bite. Immediate medical attention is advised…followed by a call to your local pest control company!
