Facts About Hobo Spiders
Not a native of the United States, the hobo spider was brought to this country via international trade from Europe. The name “hobo spider ” has been adopted because of the way it spread to various cities on railways. It has also been called the aggressive house spider, even though it has been found to be no more aggressive than any other species. You’ll find this spider in many states in the Pacific Northwest. The hobo spider was identified as a potentially harmful species in the 1980s because of its ability to leave a very deep flesh wound, similar to the ones inflicted by brown recluse spiders. However, this has since been disproven.
Hobo Spider Bites
The hobo spider will not attack humans unless it is disturbed or provoked. Whether or not these bites are really toxic is hotly debated among scientists. The hobo spider looks like several other varieties of of spiders, so being sure of their identity is difficult. Some believe their venom can cause blisters and tissue scarring similar to the the brown recluse, others contribute these bites to other spiders mistaken for the hobo spider.
Hobo Spider Infestation
When mating in the late summer, female hobo spider s will lay in their funnel-shaped webs and wait for males to approach. Males tap at the entrance of the web to signify interest. If the female does not respond, she may kill him. However, if she is receptive to the male, the male will add silk to the web and approach her. The female will lay one to four cases that contain anywhere between 50 and 100 eggs that will hatch in the late spring and early summer. Once they are fully grown, they can live up to three years.
Hobo spiders will often be found in dark places like under rocks or other organic material. In the home, they are found under foundations, or in other secluded areas where they will not be disturbed. Their webs are large, sticky funnels that trap their prey. The spider then exits to attack and ingest whatever has been trapped. This activity often occurs at night.
