Here's a paragraph I found on a page for the Hobo Spider:
For years there have been numerous reports of spider bites in the Northwest United States in which the Brown Recluse Spider was blamed, despite the fact that they reside in the Mid-Southern to Southeast United States. Brown Recluse Spiders have bite effects and symptoms that are nearly identical to Hobo Spiders. Because the Brown Recluse Spider is known more throughout the general population, they had been, and still are today, wrongfully accused of the insidious effects of Hobo Spider bites. Our traps are recommended for Brown Recluse Spiders as well.
Here's the link to the page for the traps:
