Hobo spiders (Eratigena agrestis) are not native to North America and were accidentally introduced here from Europe.

These spiders are long-legged, swift-running spiders that build funnel or tube-shaped retreats. Like most spiders in this family, hobo spiders are most active at night.

This species has received a lot of bad press because it was suspected of being aggressive and its bites were suspected of causing sores that do not heal readily. In reality, this spider prefers secluded locations and will not bite unless it is handled roughly, harassed, or accidentally pressed against your skin.

There is no scientific evidence that hobo spider venom causes death of skin tissues (necrotic lesions), if bitten.

To keep spiders out of your home:

  • make sure any small cracks and openings to your home are well sealed
  • remove spider webs from the foundation, eaves, windows, and door frames of your home
  • install good window screens
  • install rubber, plastic or brush gaskets underneath doors that lead outdoors or into garages and basements
  • seal gaps in window frames with weather stripping, wood putty, or sealant; seal gaps around plumbing with construction foam
  • watch for spiders if you bring firewood, potted plants, or other objects in from outside
  • vacuum regularly and vacuum any visible spiders
  • keep bedding several inches above the floor
  • shake clothes and shoes before wearing and shake your bath towels before using
  • Use sticky spider traps. Traps are most effective when placed on the floor in dark corners and under furniture
