PHOTOS: Hobo Spider season has arrived

KHQ.COM - Mid August is about the time that we start to see spiders come into our homes, particularly the hobo spider.

August and September is mating season for the hobo and that means you may be seeing more funnel-like webs in and around your home. Males are on a mission to find a female which is why they are a lot more active. They will continue moving from place to place, until they find a mate. After mating, the males die. Males can be distinguished from females by the "boxing gloves" in front of their head.

The hobo spider is known to be aggressive. If  you've had a friend tell you that they've been chased by a hobo, they are most likely telling the truth. The scientific genus species of the hobo is actually Tegenaria Agrestis. "Agrestis" meaning aggressive.

To prey on insects, the hobo actually sets up a funnel-like web and hides inside to wait. The web of a hobo is not very sticky so once an insect gets caught, the hobo spider has to act quickly and attack the insect to ensure it doesn't escape. Hobo spiders will commonly set up webs inside homes and they will even lay their eggs indoors. One egg can have as many as 300 baby spiders - just one more reason why people are anxious to get them out of their houses.

What does a hobo look like? They have brown solid legs and chevron markings. Range in size from 1-1 3/4 inch total including legs.

Where do they build their webs? They like to take up shop in cracks, holes or crevices of a structure. A web acts as camo for the spider to catch food.

Does the spider bite? It certainly can. A hobo spider bite can cause necrosis in some people but everyone reacts differently.

What can you do to protect yourself and your home?

  • Call the exterminator. It's not a bad idea to spray the perimeter of your home every year and even the inside if necessary.
  • Keep vegetation away from your home. It's a good idea to have a perimeter of rock or gravel around your house.
  • Keep the lights in your home off, especially at night and in your basement. Spiders know that if they find light, they will find insects, i.e. food.
  • Pick up debris and clutter in and around your house. Hobos love to hide...they will even hide in your clothes if you leave them on the ground.
