Huge Venomous Hobo Spider in My Shower! And I was late for work!

So I got in to take a quick shower before work and what do I see running across the floor of the tub? This huge furry spider full of venom. It is the venomous hobo spider!!!Show more

I learned later that is it s Hobo Spider and that they can be highly toxic, but not enough to kill people in most instances like a Brown Recluse or a Black Widow venomous spiders can.

Oddly enough, I found a Black Widow in my parents backyard over a decade ago and needless to say, my fingers were only inches away from being bitten by that beast as well.

Tegenaria agrestis is a non-native species in the United States, Hobo spiders lack the colored bands found on many spiders of the Agelenidae family where the leg joints meet.
The abdomen has chevron (V-shaped) patterns (possibly many of them) down the middle, with the chevrons pointing towards the head.
Hobo spiders have a light stripe running down the middle of the sternum. If the spider instead has three or four pairs of light spots on the lateral portions of the sternum, then it is one of the other two related Tegenaria species. However absence of spots is not conclusive proof that the spider is a hobo spider, since the spots on other Tegenaria species may be extremely faint and not readily visible.[8]
Hobo spiders do not have two distinct longitudinal dark stripes on the top side of the cephalothorax, instead showing indistinct or diffused patterns. Washington spiders with distinct dark stripes include spiders from the genera Agelenopsis and Hololena and possibly some wolf spiders. (These spiders do not have common names.)

The toxicity and aggression of the hobo spider are currently disputed by arachnologists. One common name, the aggressive house spider may arise from a misinterpretation of the Latin name agrestis, (lit. "of the fields") as "aggressive". If a hobo spider is tending an egg sac, it may become aggressive if it perceives the egg sac as being threatened.[9] However, they generally do not bite unless forced to protect themselves.

In the United States, the hobo spider has been considered to be a dangerous species based on a toxicology study on rabbits where lesions appeared after spiders were induced to bite the rabbits.[10] This laboratory study has led to the proposal that in some parts of the U.S. nearly all bites attributed to the brown recluse spider are in reality the hobo spider's bite.[11] The CDC and other U.S. government agencies[12] have also used this same study as the basis for a report claiming that the hobo spider bite causes necrosis in humans,[13] despite the absence of any confirmed cases. Subsequent attempts to replicate the study by injecting sufficient venom to ensure envenomation have failed to produce necrotic lesions, and there is even question as to whether the lesions observed in the original study were necrotic from the venum.[14]

In Canada, there are scientists who claim that no hobo spider bites lead to dermal necrosis.[15] Hobo spiders are common in Europe, though bites are relatively uncommon, and there are no confirmed reports of them causing necrosis despite hundreds of years of coexistence there. The only documented case of a verified hobo spider bite leading to necrotic skin lesions involves a person who had a pre-existing medical condition (phlebitis) that can also cause the appearance of skin lesions.
