Tegenaria & Hobo Spiders

Disclaimer: Tegenaria are very hard to tell apart and I am not at all certain that all the IDs on the tegenaria pages are correct. I have done the best I can to try and classify them correctly but would be happy for anyone to tell me if they believe otherwise - glen

Tegenaria belongs to the Funnel Weavers (Agelenidae) species which includes the genuses Agelenopsis and Hololena. Here are some photos of some of the tegeneria species - hobo spiders, Tegenaria Agrestis and their less harmful relations, the giant house spider, Tegenaria Duellica (previously Gigantea) which is a common resident of houses and other man-made structures in Europe and Tegenaria Domestica, the barn funnel weaving spider and a page of spiders I believe to belong to this species but can't be properly identified. Spiders, including the hobo spider, vary considerably in appearance, and identification can be difficult. Identification relies on an examination of the spider’s anatomy. Positive identification may require microscopic examination of the epigynum and palps.


Note the zigzag pattern on the abdomen.

Hobo Spider (Tegeneria Agrestis)

Giant House Spider (Tegenaria Duellica)

Map above shows the states in USA where Hobo spiders (Tegenaria Agrestis) are found. If you don't live in one of these states then the chances are that the spider you found is either a Giant House Spider (Tegenaria Duellica) or a Barn Funnel Weaver (Tegenaria Domestica).

The following characteristics can help in identification of hobo spiders in order to prevent mis-identification and eradication of beneficial species with a similar general appearance:

  • Hobo spiders lack the coloured 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.
  • Like other funnel spiders, hobo spiders have two spinnerets extending from the bottom of the abdomen.
  • 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 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.
  • 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 genuses Agelenopsis and Hololena and possibly some wolf spiders. (These spiders do not have common names.)

Tegenaria duellica

(Barn Funnel Weaving Spiders)
Other Tegenaria

Hobo Spiders are brown and measure roughly 12 to 18 mm in length.  Their legs show no distinct rings and have short hairs.  Their abdomens have several chevron shaped markings.  Males are distinctively different from females in that they have two large palps that look like boxing gloves.  These palps are often mistaken for fangs or venom sacs, but they are in fact the male genitalia.  The females also have these palps, but the ends are not 'swollen' as they are on the males.  Females tend to have a larger abdomen when compared to males. The hobo spider, Tegenaria agrestis, is a moderately large spider of the family Agelenidae which is indigenous to western Europe that was introduced into the north western United States (Port of Seattle) sometime before the 1930's. The means of the spiders' introduction into the United States was almost certainly commercial shipping vessels carrying cargo originating from agricultural areas of Europe. In its native Europe the hobo spider is a resident of fields, rarely entering human habitations due to the presence of major competitors, particularly the giant house spider, Tegenaria duellica, which is a common resident of houses and other man-made structures in Europe; thus, human contacts with the hobo spider are uncommon in Europe. In the United States however, the hobo spider rapidly adapted to living in urban areas, and without the widespread presence of a dominant competitor, became abundant and began to extend its range; by 1968 it had become established as far east as Spokane, Washington and Moscow, Idaho, and as far south as Corvallis, Oregon. The reason hobo spiders have a reputation for being so aggressive is because they have very poor eye sight and have to aggressively attack their prey to catch it. Their web is not sticky either which makes it harder for them to catch prey. Therefore with their poor eye sight, they think humans or anything that moves probably, are prey and attack. In around 50% of bites, no venom is injected so their reputation is probable overrated too. However when it is injected, necrosis occurs and the resulting wound can take years to heal with much skin being eaten away! hobospider.org
Please note that not all the identifications below may be correct as hobo spiders are very hard to identify positively. Check out Rick Vetter's ID sheet for more info.

Hobo Spiders -  Tegenaria agrestis
10 August, 2013:
Hi Glen, I thought I would send you a couple photos of a female Tegenaria agrestis that I found in west Spokane Wa. in a rock pile. I am one of those that like these spiders, and have kept a couple males as pets. I am also trying to 'clear the air' about the implications that these spiders may cause significant injury. Having handled these spiders and observed them, I believe they may be harmless spiders. Although I have not been bitten by them, even with some provocation, other arachnologist concur they may be harmless. This female was very passive, and after a few moments acclimated to my hands well. She is 12+mm, and a shot of her patterns on the abdomen. I hope the photos may be of use to you, and feel free to use them in any manner you like. Thanks so much, Dan (the bug man) Grafflin

Hi there! I have found a few of these throughout my house, we live in a bottom floor apartment near a wooded area in Clackamas OR. I have two little girls and I am worried about these spiders being aggressive and poisonous. This one was found right outside our sliding back door. The ones that we have found in our house have been a lot larger. I think they might be wolf spiders. Please help!! Thanks, Ashley

Good day, We just moved into a house and have seen at least 10 of these on the basement walls at varying times. Startling because they are quite large and incredibly fast. I am no arachnologist but I am a scientist and I do own a dissecting microscope. I have been researching and trying to identify whether it is a hobo spider or grass funnel weaver or something to that effect. I am pretty sure after my research that even if it is a hobo spider they are relatively harmless and not as dangerous as some people would say. Can you help me with identification. From my research it seems photos are not enough as you really need to look at the pedipalps and the reproductive parts which with my microscope I can do but still I am not a trained scientist in this field. If you need pictures of the pedipalps let me know. thanks so much Greg

Hi, Found your website online and was wondering if you could please take a look at the attached spider and help us ID it? We are located in the Willamette Valley of Oregon and have found (3) of these spiders in the lower level of our facility. Closest we can guess is it's potentially a male hobo spider? Would really appreciate your help in identifying it. They are quite large and fairly aggressive as one of our employees was charged at by one the other day. Thanks in advance, Michelle

Hello Glen, Your spider site is very helpful. I have attached two photos of decent resolution in hope that you can help me id the spider I found in my basement. I spent a lot of time on your site tonight and my spider looks closest to the hobo spider to the uneducated eye. I have a two year old and a baby due in less than two weeks so I am sensitive to anything that may be harmful in the house. Any help you could give would be much appreciated. Feel free to post these photos on your site. Thanks, Jason

Looks like one to me, but I hope you will tell me it is a good old garden variety one instead. Caught two large ones (1.5 inches with legs extended) during Aug. crossing the basement floor. We are under construction/renovation, and there are lots of cracks and crevices throughout the basement. We are slowly sealing them up. Any advice to prevent a new generation from hatching if it is a Hobo? Lorna

i have attached a picture of a Giant House Spider/ Hobo Spider (i know its incredibly hard to tell the difference between the two aside from in some examples of a giant house spider u can find stripes on the legs) that i figured u might enjoy for your website. i am terrified by spiders but got very interested in researching them when my toddler started waking up with distinct spider bites on her (this has even happened when she was in my bed and i have NEVER been bit). Giant House Spiders are recorded as being non-aggressive but there is something in my daughter they like...this big boy was a busted culprit which i was not able to catch (way too fast for me, i read they are one of the fastest spiders in the world) but i was barely able to snap this pic when i had him cornered. i suspect that she gets bit by the males during mating season (i read somewhere that this time of year the males tend to wander a lot looking for potential mates and for 2 years now she has had these bites appear in only a 2 month span) thank you very much for having that website. it has been one of my faves for looking up comparison pics and information -Jae K

Hi there, From what I can tell, these buggers are Hobos: no banding around the legs, no stripes on the cephalothorax, generally ugly. I have been finding these more and more regularly in our finished basement “after hours” before I go to bed. They always scare the heck out of me when I walk downstairs. Can you confirm? Love your site! I feel I am getting a real education about my new roommates in the basement. Thanks, Doon Seattle, WA

I love your site. Unfortunately I still have a problem identifying what sort of new 'friends' I've had try to enter my house recently. I think the one on the sticky trap is a hobo. Can you confirm that? The one in the jar I can't tell. I would love to release him in the yard if he's beneficial. Feel free to post these pics if you want. Sincerely, Bryan

My husband and I found this spider last night in our garage. We saw no web. My husband was moving a box and it fell off the box into a plastic bin we had. I quickly snapped 2 pictures and then my husband squished it (I'm sorry, but we freaked). It was about 3-4 inches in length including legs. We've seen many spiders around as we live in Portland, OR, but never the hobo or anything that looked this much like a hobo until now. We have a lot of storage boxes in the garage, so this makes me nervous. I know there are probably many more out there...are we okay just being careful, or do we need to do something about them? Thanks Jenny

Hello, I live in Portland, OR and have TONS of these spiders (pic attached) in my finished basement. We think they are either hobo spiders (hopefully not) or giant house spiders. We have been seeing them since late spring and throughout this summer. Lately, it has been quite hot outside and now we are seeing what appear to be that same type of spider only now they are huge. I have found 5 in our house in the last two days all of which were at least 2 inches in diameter, and have seen at least 75 of varying sizes total over the past two months. It's making us a little uneasy not knowing whether or not they are poisonous. I have attached a photo for your reference. Please help! Thanks!

This spider is living in a yard debris bin that's full of dirt. Portland, Oregon. Summer. What do you think? Hobo? It has eaten another spider. I tried to include a picture of it's web. No funnel that I can tell, but it's also been disturbed, so It's hard to tell the intended shape. If it's a hobo spider, how do I get rid of it (and others)? I have a toddler and the last thing I want is for her to find it. -Courtney

Reply: This looks like a hobo spider. I would take the spider and your daughter to the dr if the welt gets any worse. It is definitely one of the tegenaria species to which the hobo belongs and the hobo does not have striped legs same as yours. So best to be safe with your daughter!!

Either it got back in or I found another one. This one was brown with the same markings. I could swear the first one was green, even my son said it was green, but we were also looking at it through a glass in poor lighting. This time it was on the curtain right by the foot of my bed. I'll try to see if I can get the photos attached. They are not great, but hopefully they work. The pic with the spider in the glass... the mouth of the glass is just under 3 1/2 inches wide. The glass also has a bubble design which distorts the image of the spider a little. Can you tell what it is? The next time it gets back in, should I put it outside again, or should I be getting rid of it? Thank you. Johanna

We have a debate on Facebook whether it is a Hobo or a Grass Spider…or maybe even your common giant house spider…please help J

We found it on Anderson Island in Tacoma, Washington. And yes, the pediapalps are larger on the ends, look more like legs than anything. It’s 2.5” across span to span and about 1.5” in length.

Hi Glen! Great site! I've been trying to figure out what kind of spider this is. Any Ideas? I live in the Upper Peninsula of Michigan (City of Hancock). Found it under a shoe at night time, and another the same night scurrying across the floor. They're huge! The attached photos are ones of a smaller spider than the one we saw running across the floor. One photo is of the underside, and is labeled as such. Thanks for any help you can provide! There's so much confusion up here about what these spiders actually are, whether they're wolf spiders, brown recluse, or giant house spiders. These spiders seem to be very common in houses here, especially old ones. My house is ~112 years old. Thanks for your time! -Ryan Lucas

Awesome site and you've never let me down. Found a few of these in the traps this weekend. I believe spider1 is a hobo but I have seen SO many funnel weavers and hobo pictures.. it looks like it could be either. I am in Utah, USA. We have small children and I really need to rid the area of hobos if we have them.. Our playroom is in the basement. I sprayed for spiders inside and out yesterday but that spider1 was in the trap this morning. The second spider I have no idea what it is. Both were in traps.

Reply: It's a bit hard to tell from these photos but this could be a hobo spider. Hobo spiders don't have very hairy legs like other tegenaria species and have no banding on them.  It could also could be tegenaria gigantea, the giant house spider which is in the same species.

Hi Glen, I just found your site, it's so great, congratulations and keep it up! I have recently got interested in my spiders -- they thrive around my house (Seattle, WA) at this time of year -- I used to be scared to death of spiders but I started to photograph them and starting to see the beauty in them I'm less scared! I was wondering if you could tell me if this is a Hobo spider, it dared to walk across my living room while I was playing the piano... (2 pictures)  Also I was wondering which spider is the one photographed outside on the rail of my balcony. It had really, really long legs. (1 picture) Thanks a lot for your help! Françoise

Hi Glen, My husband found this spider in our garage while cleaning it. We live in Albany, Oregon. I'm not sure what it is but it was very fast and the biggest spider I've ever seen in real life. I would guess it to be almost three inches including legs of course. Please help us identify it, I got the best picture I could, it was on the move, and cropped it in hopes of seeing the markings better. I will send you the originals and the cropped.
Thank you, Larissa

A few nights ago, I found an unusually large spider in my bathroom. Iʼve been looking around, doing some research, and happened upon your website. My spider has the appearance of a Hobo Spider. That would make sense, seeing as I live in a city just outside of Seattle. I would estimate about 4 to 5 inches from leg to leg. I tried my hardest to get a closer picture, but this sucker moved very quickly. I was lucky to get even on shot.If you could try to ID this little bugger, and let me know what you think, thatʼd be great. Thanks, Zach

Hey its David here,
(The same David who sent the Daddy long legs photos) I'm pretty fascinated by spiders still, not so scared but still if theres one thats walking around on my wall I don't like to leave it there. If they are staying still just living I don't usually mind. Anyhow yesterday there was this rather big one on my wall (Big for the UK I think anyway), I caught it and got a nice photo of it. I'm really curious if you can identify it because i'd really like to be able to identify any spiders that venture into my room. I'm kinda turning into a spider enthusiast! Hope you enjoy the photo! Many thanks!

Hi !  Hope you can help me, I’m Hélène, I’m French and I’ve found these spiders in an old castle this summer. The 1st one was 15cm long, and I don’t find what it is, I know the 2nd one I just wanted to send you this picture, in French it’s called “tégénaire”. Besides, recently I saw a pink one crossing a road! It was not my imagination!!! I didn’t have enough time to see it closer, and I can’t take any picture…Please tell me it was the reality…
Thank you in advance. (Fantastic site!)

Reply: Tegenaria agrestis is commonly known as the hobo spiders and their bites can be quite bad become very infected with the skin necrotizing.  However not all bites have poison injected, many are dry and this does then not occur.
