Considering it is well known and accepted the Hobo infestation started in the port of Seattle sometime before the 1930's, this issue has become an interesting head scratching case of denial. Most people bitten and envenomated by Hobo or Recluse spiders do not feel the initial bite and do not see the biting spider. More serious bites occur when the Hobo is trapped between clothes and skin and is trying to get away. However, if caught between skin and clothing or bedding it will almost always bite you. Many bites occur this way.
Most bites are defensive in nature and lightening fast.
The spider is simply trying to get away. We recommend keeping clothes, shoes and bedding up off the floor. Click picture for larger view. Top view of a male Hobo. Hobo spiders are most active during the months of June to late October, when the males are widely roaming and entering homes looking for females.
