Did they *SEE* the spider bite them?
Or did they wake up with a painful wound and assume it's a spider?
The lesions that were caused by a "Hobo" spider are usualy not so at all.
And if any of them WERE indeed Tegenaria agrestis bites, they were a personal reaction.
I have been bitten by this species before, with no lesions what so ever.
Not trying to be a know-it-all or anything, just trying to clear the reptutation for this beautiful species.
