Giant House Spider (Eratigena atrica). Tegenaria duellica/gigantea and T. saeva were synonymized with T. atrica and moved to the new genus Eratigena as of August, 2013. Eratigena is an anagram of the genus name Tegenaria (Bolzern et al. 2013). The specific epithet, atrica, is formed from atri- after the Latin noun for “atrium” with the addition of the -ica suffix meaning “belonging to” (often used when referring to habitats). So “belonging to the atrium” is a basic translation. This makes sense, as Koch mentions in his original (German) description of the species that he found it in a glass botanical house in Erlangen and that it also liked the warm spots on the interior of homes (Koch 1843). Notable Previous Names Previous names/synonyms of this species include Tegenaria gigantea, Tegenaria duellica, Tegenaria saeva, and Tegenaria atrica. The current name, Eratigena atrica, was published by Bolzern et al. 2013.

The Giant house spider is a close relative of both the Domestic house spider and the infamous Hobo spider. The bite of this species does not usually pose a threat to humans or pets. Females can reach 18 mm in length, with males having a slightly smaller body at around 12 mm to 15 mm in length. The female leg span is typically around 45 mm. The leg span of the male is highly variable, with spans between 25 mm to 75 mm being common. The Giant house spider has the same colouration as the Domestic house spider; it has earthy tones of brown and muddy red or yellow. They also have conspicuously hairy legs and abdomen. The Giant house spider is indigenous to north western Europe. It was however unwittingly introduced to the Pacific Northwest of North America around 1900 due to human activity and strongly increased in numbers for the last decade. The webs built by the Giant house spider are flat and messy with a funnel at one end. The spider lurks in the funnel until a small invertebrate happens to get trapped in the web, at which point the spider runs out and attacks it. They usually build their webs in corners (on both the floor and ceiling), between boxes in basements, attics, or any other area that is rarely disturbed by large animals, or humans. Males can often be seen wandering around during the late summer and early autumn looking for a mate. A population of Giant house spiders is popularly thought to be a deterrent to the establishment of Tegenaria agrestis, known in North America as the hobo spider, and considered by some to be more likely to bite humans. Giant house spiders may compete with hobo spiders for the same resources. Hobo spiders grow no more than a body size of 15 millimetres (0.59 in) long as where the larger female giant house spider can have a body size of 18 millimetres (0.71 in), but has proportionately much longer legs.

Sorry I emailed you before but didn't put any information. This spider is like a brownish colour, I would say about 3inches- 4inches in size, as you can see from the picture it has fangs. I live in england, london, I found it in my kitchen at night as I turned on my light.

I live in the Pacific NW and have found this guy/gal living in one of my bathrooms. My wife and I rarely use the room and I find this spider very interesting. Can you confirm that this is a giant house spider? He/she is about the size of a pool ball in circumference. If it's a Hobo I'll remove it. Thanks, John

Hello, I currently live in Vancouver, BC, CANADA and I found the following large spider in the kitchen sink at 5am this morning. It was a really large one and brown and I can say that I was not exactly happy to see this at that time in the morning. I am sorry about the quality of the pictures, but that was the best I could do at that time in the morning.

My son took a picture of this spider after my other son was bit by a spider, not too sure it’s the same spider that bit him but it was the only one he could see. He says it was about the size of a quarter. We are in southwestern Ontario if location helps at all.

Hi there, I caught this mean looking mother in my garage at home (UK) and was quite shocked by it! There are 3 photoes there that should zoom in OK, the 3rd one is poor as it is shown through a blue bit of plastic, but you can see the profile of it. The other 2 show clearly the abdomen and yellow colouring. Kind Regards, Adam

Hey Glen, Just found your site via google - my roomates and I in Germany just found this guy on our wall and it freaked us out. Attached are a couple hi-res photos i took of it - is it dangerous at all? I also saw a clear-see through baby spider on my sandal this morning, could it be related or a baby of this? Very freaked out at the moment so your help will definitely be appreciated! Thank you, Jonathan

Hi Glen When doing a bit of research this morning I found your site, spiderzrule.com and thought I'd send you a picture for your collection. I came across the subject of the picture this morning when lying in bed. It was on the wall about 2 feet above my head and just quietly walking by when my 12 year old daughter entered the room and spotted it immediately (and just about had a seizure). I guess it's not quite as big as some of the others listed but it's about as big as any I've seen in the wild in the UK (I live just outside Glasgow in Scotland). From its characteristics I'm guessing a giant house spider? Feel free to use the pic on your site if you wish. Cheers Colin

Hi Glen, While in Canada (Nova Scotia) I took these spider pictures. I was hoping that you might be able to help me identify them.  The last three I think are some sort of sheet spider. 8358 and 8362 are of the same spider. It is the spider that is under the one sitting in the web in 8355. Thought they all could be the same species and some sort of common Canadian house spider. What do you think? Thanks, Tracy

Hi, I found your site, spiderzrule, after we captured a spider in our kitchen. My wife and I have no idea what it is, she thinks it's a Hobo Spider, but I think it's probably a garden spider/funneling spider after viewing some of the pics on your site. We just wanted to be sure! I haven't been able to find a spider with the types of markings that this one has, and I have NEVER seen one this big in all the years I've lived up here! We live in Vancouver, Washington, USA if that helps. Also, the glass it is under is pint glass for size relation. Thanks for taking a look! And feel free to use this pic however you wish! - Tom

Reply: The pattern on the abdomen is more like that of tegenaria gigantea than a wolf spider.

He's a BIG ONE!!! that is a wolf spider? He didn't run from me but at me! Thanks

Hey Glen - Here are a few spider pics from recently caught critters. The last three images are of a small example of the spiders we routinely catch and release; have seen these guys with a body the size of a large wasp and leg spans reaching 2.5" to 3", pretty sure its a wolf spider of some sort...but it does have a set of 'spinners' or some such on its butt, so maybe a grass spider variation?? I only recently got a decent digital cam; and finally started playing with the macro mode, so have been clicking as I catch. All of these are crops of the originals to clip away wasted surround; so quality may be slightly reduced as a result, if the original ~4mb file would help with the ID, I still have it kicking around the drive here somewhere... Catch ya Later, Mac.

Reply: As you are in Abbotsford, BC, Canada, it is not likely to be a hobo spider but could be tegenaria gigantea, the giant house spider which is in the same species.

Reply: You have 2 funnel weavers, that's the stripey ones and the other with the big "bum", looks like tegenaria gigantea - the giant house spider, a relation of the hobo spiders which actually kills hobos if you have them in your area

I caught all these in a cup after finding them on some boards in my backyard. I live in Utah, USA. The one on the top and bottom look similar but the one of the right had a HUGE "bum". Thanks! Dustin

Reply: It looks like a species of Tegenaria to which the hobo spiders belong. But not sure if it is Tegenaria agrestis or maybe Tegenaria gigantea.

I recently found your site. I dig the content due to my strong curiosity  for all things eight legged. I took these photos about a year ago, and have been passed one answer or  another the whole time as to the species of the spider. After browsing your  site I am led to believe that the two spiders photographed are a type of  common house/grass spider, but I want to be for sure. If you could take a  gander and try your hand at I.D.ing the spiders (Which appear to be a  male/female of the same species) I would be grateful! Again, awesome site and keep up the good work! Spiders are misunderstood!-Jeff

Another observation: Hi, Just wanted to chime in on your posting in your Hobo Spider section of a specimen dated 30 July, 2007 and identified as Tegenaria Domestica. The size is about right, but the coloration isn't. It seems to me that he's a little too yellow for Domestica, but not for Agrestis or Gigantea. I could be wrong, but I think this is a small Agrestis. The legs are absent of the black bands that are a singular feature with Domestica. That's my main reason for questioning the ID. Lower down, you have a picture dated 3 February 2006 which is a good example of Domestica. The bands can be seen clearly (though upstate NY seems quite a ways from home for Tegenaria. Stowaway perhaps?). Anyway, just an observation which I thought might be useful. I'm but an armchair expert. Love the site. Refer to it all the time, just because I love to  look at spiders. My youthful fear of spiders has grown to respect,  and finally to love. Fascinating creatures. Jake in Portland Oregon

More: Upon further investigation I have narrowed it to a male Tegenaria domestica. Thanks for the help in narrowing it down. Keep up the good work. Josh

Hi, I am a university student in Victoria, BC, Canada. I was working in a forest in the area when I found this little spider. It was about the size of a quarter to my best guess. I think it may be a type of wolf spider but the markings kind of threw me off a bit. It certainly has 8 eyes though. Beautiful whatever it is. Thanks for any help! Josh Victoria, BC

Hi Glen, My name is Aimee and I am from Portland Oregon. I was wondering if you knew what kind of spiders these are. I found the one in the cup in a piece of wood in my garage. I found the one in the dirt in the actual wood shed so I am guessing that they are both wood spiders. If you have any idea what kind these are then please let me know by E-mailing me back. I have checked your spider site to see if they were there but I couldn't find them. thanks, Aimee
