So far as known, all spiders, except the small
family Uloboridae, are venomous. However their
venom is mostly adapted to affect their prey, which
is usually an invertebrate animal, and normally has
little or no effect on a vertebrate, especially one
as large as a human being.
There are only a very few spiders whose venom
causes serious problems to a human, and even
then fatalities are normally limited to childres or
adults who are already in poor health for some other reason. Several more species can produce
an effect about equivalent, in pain, to a bee sting.
The bite of most spiders seems to be either
quite without effect, or no more thatn getting
scratched by a bramble or pricked by a pin. I have
handled hundreds of spiders and can remember only one good bite. It took me a couple of minutes
to persuade it to let go, and there was no effect
of venom at all.

Many wolf spiders are very large, members of the genus Hogna are quite big, and very nasty looking. Here are some neat facts about wolf spiders. Well first of all, they are in the family Lycosidae, they are found all around the world except the poles, but they actually get pretty close. I have seen studies done on them in the high arctic and Alaska, so they are pretty cold hardy as well.
They are very common in open areas, lik agricultural fields, roads, rock faces, things like that. The entire family are terrestrial hunters, they dont make webs to catch food, they are simple chase and capture hunters. Some make underground burrows (much of the larger specimens).
One thing you absolutely have to try is night spotting for wolf spiders. In the middle of the summer when it is pitch black out at night, go out into a corn field with a head lamp on, you can actually see all thier little eyes shining back, it is really cool.
Well trained arachnologists can actually identify many of them to species, just by their eye shine, pretty neat stuff.
Wolf spiders carry thier egg sacs under the abdomen, it is usually attached to the spinerettes. When the young hatch they will remain on the mother's back for some time before dropping off and fending for themselves.
I have only ever been bitten once by a wolf spider. This isnt an old wives tale either (many people always beleive they are bit by spiders in their sleep???)
I was actually sleeping in this very shotty cabin, and one climbed onto my shoulder, not knowing what it was, I tried to rub it off and in the process, it bit the soft skin between my thumb and forefinger. Let me tell you it hurt!!! I was swollen for at least 3 days if memory serves me right. My hand was very sore and it was tough to move my thumb.
But you know what I never killed the spider, I actually let him (her) go outside, I figured, hey I assaulted her, she was just defending herself............
So, sorry about the rant there, I love spiders......
to answer your question, yes they are all venomous, all spiders are, no ifs ands or buts about it.
The bite is very painful.
There are thankfully no long lasting effects or severe necrosis from thier bite.
If you are from the cental or souther united States or Europe then you have some mighty big specimens on your hands there, but arent they awsome???

Wolf Spiders
Habitat: Common household pest in the fall when they are looking for a warm place to overwinter. They are commonly found around doors, windows, house plants, basements, garages, and in almost all terrestrial habitats. They do not spin a web but roam at night to hunt for food. Wolf spiders are often confused with the brown recluse, but they lack the unmistakable violin-shaped marking behind the head. The wolf spider is shy and seeks to run away when disturbed.
--------------------------------------------------------------------------------
Description: Wolf spiders range from about 1/2 inch to 2 inches in length, hairy, and are typically brown to gray in color with various markings or lines. Wolf spider mothers carry their large egg sacs around with them. When the young spiderlings hatch they climb onto their mother's back and ride around until partially grown. Wolf spiders are not poisonous, though as with all spiders, bites may cause reactions in certain individuals.
INTERESTING FACTS: Most homeowners have misconceptions about spiders-they are pictured to be poisonous (even deadly), and likely to attack at any time. Wrong. The only dangerous spiders we have in Virginia are the brown recluse spider and the black widow spider. The brown recluse is not common. The black widow is common, but reports of it biting people are infrequent. For the most part, spiders are beneficial, eating insects and other spiders.
CONTROL: Spider control is best done on a one-to-one, as needed basis. A general spray for spiders is not recommended, unless the infestation seems severe. Tolerate what you can, spray with an aerosol what you can't.
Venom toxicity - the bite of the Wolf Spider is poisonous but not lethal. Although non-aggressive, they bite freely if provoked and should be considered dangerous to humans. The bite may be very painful. First aid and medical attention should be sought as soon as possible, particularly as to children or the elderly.
Area of distribution - Australia-wide.

I think they are the ones that live in a hole in the ground and have a ring of web around it. I assume all spiders to be poison since that is how they kill insects. I also assume that their toxin is not deadly to humans but I would not want to get bit by one. They are somewhat aggressive if pestered. They also come out of their holes really quick.
