Jumping spiders are fascinating creatures known for their unique hunting techniques and impressive agility. These small arachnids, often sporting vibrant colors and identifiable markings, are commonly found in gardens and around homes. While their appearance and behavior may intrigue many, a common question arises – do jumping spiders bite?

In general, jumping spiders are not considered dangerous to humans. Though they possess venom used for incapacitating their prey, the majority of bites inflicted on people result in mild symptoms, such as temporary pain and swelling at the bite site. However, it’s important to remember that individual reactions may vary, and it’s always best to exercise caution when interacting with these creatures.

Jumping Spiders Overview

Jumping spiders belong to the family Salticidae, which consists of over 6,000 species. They can be found in various habitats such as gardens, homes, and other outdoor environments.

These spiders are known for their colorful appearance and eight eyes that provide excellent vision. Some common species in the United States include the Phidippus audax and Salticus, which display striking black, white, yellow, or orange patterns.

As carnivores, jumping spiders primarily feed on smaller insects and rely on their excellent jumping abilities to catch prey. Their leaps can be many times their own body length, which helps them ambush prey effectively.

When comparing jumping spiders to other spiders, some key features to keep in mind are:

  • Eight eyes with exceptional visual acuity
  • Impressive jumping abilities
  • Colorful, vibrant markings


  • Effective at controlling insect populations
  • Generally not aggressive towards humans


  • May be unwelcome in homes or gardens due to their appearance

In conclusion, jumping spiders are fascinating creatures with impressive abilities and vibrant appearances, making them an essential part of our ecosystem.

Do Jumping Spiders Bite?

When Do They Bite?

Jumping spiders, members of the spider family Salticidae, usually bite humans when they feel threatened. Since jumping spiders don’t build webs, they rely on their powerful jumps to catch prey and escape danger. This means they are more likely to bite if cornered or provoked.

Bite vs. Poisonous Spiders

Jumping spiders are not considered dangerous, and their bites are painful but not deadly. Poisonous spiders, such as the black widow or brown recluse spiders, are more concerning due to their venomous bites. The table below compares jumping spiders with those more dangerous species:

Spider Bite Danger Level
Jumping Spider Painful Low
Black Widow Venomous High
Brown Recluse Venomous High

Signs of a Jumping Spider Bite

A jumping spider bite may have the following features:

  • Localized pain at the bite site
  • Redness and swelling
  • Non-severe symptoms, such as itching

Jumping spider bites are typically less severe than bites from poisonous spiders like the black widow or brown recluse. These more dangerous species can cause symptoms such as:

  • Severe pain
  • Muscle cramps
  • Nausea
  • Fever
  • Difficulty breathing

If unsure about a spider bite, seek medical attention to ensure proper treatment and care.

Bite Symptoms and Effects

Mild Reactions

Jumping spiders are usually not dangerous to humans, and their bites often result in mild reactions. Some common mild symptoms of a jumping spider bite may include:

  • Itching: Can vary from mild to intense, leading to discomfort
  • Redness: The bite area may become reddish due to inflammation.

For example, a person might experience a small red area with itchiness around the bite site, which usually subsides within a few hours or days.

Serious Reactions

Serious reactions to jumping spider bites are quite rare but should not be ignored. If a person develops any of these symptoms, they must seek medical attention:

  • Pain: Intense pain radiating from the bite site, which requires immediate attention
  • Nausea and vomiting: Persistent feelings of nausea and episodes of vomiting
  • Muscle cramps and weakness: Severe muscle cramps and overall weakness in the body
  • Dizziness and breathing difficulties: Feelings of dizziness, shortness of breath, or difficulty breathing
  • High blood pressure, anxiety, and restlessness: A combination of these symptoms should be taken seriously.
Mild Reactions Serious Reactions
Itching Pain
Redness Nausea and vomiting
Muscle cramps and weakness
Dizziness and breathing difficulties
High blood pressure, anxiety, and restlessness

As the table shows, mild reactions like itching and redness can be easily managed, while serious reactions require professional medical assistance. It’s important to note that these symptoms can vary depending on an individual’s sensitivity to spider venom. Always seek professional help if severe symptoms persist.

Medical Attention and Treatment

When to Seek Medical Help

Jumping spiders rarely bite humans, and their bites are typically harmless. However, it’s essential to monitor for severe symptoms that may indicate a venomous spider bite. Seek medical help if you experience:

  • Chills or fever
  • Intense sweating
  • Difficulty breathing
  • Rapid heartbeat
  • Blurred vision

Treatment Options

For most jumping spider bites, simple at-home treatments can alleviate symptoms and promote healing. Key steps include:

  1. Clean the bite: Gently wash the area with soap and water.
  2. Reduce swelling: Apply a cold pack or ice wrapped in cloth to the affected area.
  3. Relieve pain: Take over-the-counter pain relievers, such as ibuprofen or acetaminophen.

For more serious symptoms, a medical professional may administer antivenom or other treatments, depending on your condition.

Pros and Cons of At-Home Treatment:

Pros Cons
Easy to apply Not suitable for venomous bites
Cost-effective May not be enough for severe symptoms

Remember, always seek medical help if the symptoms worsen or persist.

Prevention and Safe Coexistence

Managing Jumping Spiders in Your Home

Jumping spiders, such as Phidippus audax, are generally harmless to humans and pets. They are mostly found in gardens and around homes. To prevent them from entering your home, you can:

  • Seal cracks and gaps in your walls, doors, and windows.
  • Install screens on windows and vents.
  • Keep your home clean and free from clutter, particularly in corners and storage areas.

If you encounter a jumping spider indoors, you can safely capture the spider by using a cup and a piece of paper. Then, release it outdoors. Jumping spiders are not venomous, and their bites are rarely harmful, but they might bite if they feel cornered and threatened.

Insecticides and Alternatives

Using insecticides to control jumping spiders is generally not recommended due to their beneficial role as a natural insect pest control in gardens. Furthermore, they have excellent eyesight and can often avoid insecticide-treated areas. Some alternatives to insecticides include:

  • Encouraging natural predators like birds and other spiders by creating a friendly habitat in your garden.
  • Using sticky traps to capture spiders, but keep in mind that it might also capture other beneficial insects.
  • If you’re experiencing an infestation, consider consulting with a pest control professional to discuss non-chemical options for managing jumping spiders.
Method Pros Cons
Natural habitat Encourages biodiversity and reduces insects May also attract unwanted critters
Sticky traps Non-toxic and easy to use Might trap other beneficial creatures
Pest control Professional guidance for management Can be costly and might involve chemicals

Remember, jumping spiders are generally harmless and friendly towards humans and pets, so coexisting with them should be prioritized over actions that might pose harm to these beneficial creatures.

Letter 1 – Jumping Spider, but which one???


Red Jumping Spider
September 17, 2009
Middle of September, ’09, Central Oklahoma, USA. Found in grassy back yard near structure while mowing the lawn. It really irritates me that I don’t know this one. When I was in grade school an entomology professor/uncle of mine had me catching these guys for a paper he was writing on them. I think that he was naming the species. Now it’s nearly 50 years later and he’s gone and I don’t remember if he ever told me what he was doing with these red jumping spiders. There seems to be a few closely related species that inhabit the same area and vary only slightly in the markings. I have always thought that this was an exceptionally aesthetic little creature. As memory serves they are very fond of woodpiles. I would love to get a common name for this one but considering the connection a species name would be golden. Thank you.

Dear J,
We are most touched by your letter.  Though we haven’t the time at the moment to try to research your request, we will post your letter and photo and perhaps one of our readers will be able to supply you with the answer.  We are linking to the BugGuide section on the Jumping Spider family Salticidae as well.  We believe your spider is in the Subfamily Dendryphantinae.

My research is indicating Phidippus apacheanus as the species. I still haven’t a clue as to who named it.
Thanks so much for your atttention.
J. Hopkins

Update from Karl
September 18, 2009
Hi Daniel:
It looks like another jumping spider in the genus Phidippus (Salticidae: Dendryphantinae: Dendryphantini), possibly P. clarus or P. pius, but most likely P. cardinalis (the Cardinal Jumping Spider). Based on the numerous photos on the Bugguide site, this looks like a male. Regards.

Thanks Karl,
I am familiar with P. cardinalis, we have them here, too.  Generally P. cardinalis is a bit
larger, esp females and has markings on the abdomen that are not present in
P. apacheanus.  P. cardinalis has a light line running around the for part of the abdomen and sometimes tiny light spots about middle dorsal of the abdomen.  I am not familiar with any markings on P. apacheanus, just the red head and abdomen and black legs.
I believe we have Phidippus clarus as well, or I have seen it somewhere, and it has a black cephalothorax as do many Phidippus, as well as bright markings on the abdomen.
Phidippus pius lacks the black legs but accounting for individual variation is a possibility but I think that pius is a larger species.
It is not my intent to be argumentative or mistrusting of the experts.  I’ve never taken a single class in entomology and only worked with a few relatives and friends that were entomologists.  However, to me it still looks like P. apacheanus and I have only a marginal degree of faith in that identification.
There is some speculation that P. apacheanus is a velvet ant mimic which are common here and sport the come color and pattern.  I have my doubts on this as the spiders seem to stay off of the ground where the wingless wasps frequent.  The spiders are about half the size as well.
I’ll attach a few links to Phidippus apacheanus pics:
. . . and thanks so very much.  Alternate opinions from interested and well-trained persons is highly valued.  It could well be that you know something that I don’t.  Thanks again,
J. Hopkins

Another Update from J. Hopkins
September 19, 2009
But I am seeing several examples where it appears that cardinalis and apacheanus have been misidentified one for the other.  I am not sure that some of the web posted identifications can be trusted.
Thanks again,
J. Hopkins

I have a lot of these spiders showing up in my house, more since the cold weather has set in. They move really fast and seem to jump while on flat surfaces.
I live in CT in a wooded yard, I dont see them outside too much. I think they nest in my hatchway area.
I’m curious to know if they are harmful to my cat. He has eaten quite a few and doesn’t show any signs of illness.

Jumping Spider

Dear K. Hart,
It is impossible to determine the exact species of your spider, but we are certain it is a Jumping Spider in the family Salticidae and we suspect it is in the genus
Phidippus, possibly in the Phidippus audax group which you can find on BugGuide.  Jumping Spiders are harmless and they pose no threat to you, your family, your pets or your home.  They will prey upon other unwanted visitors in the home.  It is quite curious that you have significant numbers indoors.  We haven’t heard any previous mention of Jumping Spiders seeking the shelter of homes to pass the winter months.  Jumping Spiders are hunting spiders with excellent eyesight.  They do not spin a web to trap prey.  They stalk prey, including flies and other insects, and pounce on them from a considerable distance.

Thanks for the reply. I’m glad to know there is no threat to us or the fur kids.

Letter 3 – Jumping Spider: Paraphidippus aurantius


Shiny green spider
My husband took a video of this gorgeous little thing and it jumped right onto the camera lens! The closest picture I’ve found online is a Cosmophasis (specifically the picture labelled Cosmophasis ZZ059 on the page /australian/salticidae/Saltici dae.html) …but Wikipedia claims that "some species occur in Africa, while most are found in Southeast Asia, down to Australia." This spider was filmed and photographed in Fayetteville, Arkansas. 🙂 Regrettably, most attempts to look up a shiny green jumping spider on the web come up with…well, the "Green Jumping Spider", Lyssomanes viridis, which this puppy -clearly- isn’t. Thanks for any help you can give me. We just moved here from Dallas two months ago, and rented a house in a semi-rural setting, and we’re very much enjoying getting to know all the wildlife. We have cows, deer, and every kind of spider known to Arkansas! 🙂
Ro Windwalker

Hi there Ro,
Clearly you are a detail oriented person, and you will probably not content yourself with the general answer we are going to give you. This is a Jumping Spider in the Family Salticidae. Most Jumping Spiders, and there are many, do not have common names. BugGuide shows four pages of subfamilies and each of those have additional genus and species identifications. The folks associated with BugGuide are far more organized and technical than we can ever hope to be. We really don’t have the time to sift through all of the photos to provide you with an exact identification, but perhaps you might be curious. Just follow the link we have posted on our site and start to look through images. This is how we do most of our identifications. If you get the answer, please write back and we will post it.

Update: (06/30/2007)
ID of “shiny green spider” from 6/28/07 I believe I’ve found the shiny green spider submitted by Ro on 6/28/07. Here’s a link from the University of Kentucky Entomology website for you to look at and see if you agree. iles/casefile/spiders/jumping/ jumping.htm#para The spider is the Paraphidippus aurantius.

Found this fellow on the sliding patio doors to my deck. I live in the middle of an oak forest so spiders are abundant and I consider them my friends. This was the second time I have seen this particular species and I knew it was a jumper from its behavior. From what I can gather it falls in the Habronattus genus. Can you further identify it or give me any other information on it. Twice, while being photographed, it jumped up onto my camera! Thanks for your wonderful site.

Johnson’s Jumper, we believe

Dear Noah,
Congratulations on self-identifying your Jumping Spider in the family Salticidae.  We believe it is in the genus
Phidippus, a group with many highly variable and similar looking species.  The closest match we could find is on the Pest Control Canada site, though it is most certainly NOT a pest, and it is identified as a Johnson’s Jumper, Phidippus johnsoni.  According to the University of British Columbia Biodiversity site, the species is relatively common in the area.  There is also a similar looking image from Seattle on BugGuide.  According to BugGuide, the Johnson’s Jumper is:  “Mostly black with a red abdomen. The male’s abdomen is entirely red, whereas the female’s abdomen has a black mark down the center.”  That means your individual is a female.

Hello Bugman!
I found this little spider while driving out of a Walmart parking lot. As I picked up speed she started to skitter across my windshield! I thought the poor thing would get blown off and run over for sure, so I pulled into another space and went to go put her in a tree or bush or something. But when I saw her dorsal side I couldn’t believe how beautiful she was, and snapped a picture of her. As soon as I did that, I looked around and was worried she would get hurt by someone who isn’t as tolerant of the little creatures as I am. So I decided to capture her and bring her to my house, the least I could do is feed her a few times and then let her go to protect my home from more troublesome bugs. At the moment she’s sucking the juice out of a cricket I bought for her, and has full reign of a critter keeper, and meanwhile I’ve been looking and looking online though and can’t quite decide what species she is. I’m thinking a Phidippus species of some kind, but would appreciate a more educated guess!
Thank you so much, I love your website! (Except for the Unnecessary Carnage section, so sad!)

Hi Jorie,
While we are not completely convinced that your Jumping Spider needed to be rescued, your sensitivity to its possible plight has made us decide to award you the Bug Humanitarian tag on this posting.  We are not certain of the exact species identity for your spider, but we agree that the genus
Phidippus is very likely.  That is a large genus with many similar looking species and many species that are highly variable.  We believe the closest match is the putnami group.

Letter 11 – Jumping Spider vs. Japanese Beetle


Spider v. Japanese Beetle
Hi Mr. Bugman,
I love your site and have learned much from it. Thank you for all your hard work. The fuzzy legged spider in the attached photo was sizing up a Japanese Beetle on my rose bush located in Sinking Spring, PA. They both were about the same size so maybe the encounter ended in a standoff. I’ve scrolled through your site but didn’t find anything that looked like this spider. Can you help in its identification? Thanks for your help.
Bob & Elena

Hi Bob and Elena,
We talked to Mom today who lives in Ohio. She said the Japanese Beetles had appeared. I said that we have never gotten a photo of one and lo and behold your image arrived. Your spider is a Jumping Spider from the Family Salticidae. They do not build webs, but prefer to stalk prey diurnally using their keen eyesight.

Letter 12 – Jumping Spider: What Big Eyes You Have!!!


Dear Bugman
Just by chance, I ran into your wonderful website. I wonder if you can help me identify this spider. They tend to hang out on my wooden patio chairs and pounce on flies.

Hi Shouqin,
Your photos are beautiful. We really can’t tell you much more than this is a Jumping Spider in the Family Salticidae. It could be a Metaphidippus species. We found an image online that seems to match your eye pattern.

Dear Tharindu,
This is going to take a bit more time to research than we are able to provide this morning.  We can tell you this is a Jumping Spider in the family Salticidae, and Jumping Spiders are hunting spiders that do not build webs to trap prey, though they are known to spin shelters like the one you discovered.  The really curious point for us is if you look closely at the image with the shelter, you will see a second set of eyes beneath the spider.  We believe your jumping individual is a male, and he may have been visiting a female in the shelter.

Letter 14 – Jumping Spiders: Mating Ritual? or Males vying for dominance???


Jumping spider mating display
October 31, 2009
I was working in my backyard today when I noticed these two beautiful little jumping spiders. The male was trying to convince the female that he would make a good mate. He would approach the female with his arms raised and vibrate his pedipalps. When he would get close, the female would chase after him like she was going to eat him. Eventually the male decided that it wasn’t worth the risk and ran away. The male was about 1/4 of an inch long, and the female was about 1/2 an inch long. They had gray bodies and brilliant gold hairs covering their legs. Any help you can provide in identifying these little beauties will be very appreciated. Keep up the great work.

Hi Josh,
We believe your spiders are Phidippus mystaceus based on images posted to BugGuide, but we also suspect this might be two male spiders vying for dominance.  The male spider is a perfect match to an image on BugGuide.  The coloration and pattern of the females posted to BugGuide are significantly different than in your photos.  The images are quite amazing.

  • This is a female Phidippus clarus.

  • Following your idea that this jumping spider is of the subfaily Dendryphantinae… could this little guy/gal be of the Genus Phidippus? I think this could be a match for the picture posted

    • The genus Phidippus was our original suspicion, but we hadn’t the time to research this more closely yesterday. The photo that you have linked to looks quite close, but sadly, the image that was sent to us is lacking in clear details, so exact identification might not be possible. Even the specimen on BugGuide does not have an exact species identification. Many members of the genus Phidippus are variable in coloration. It is possible that J’s uncle was trying to identify a previously unidentified species or subspecies, but whether or not the proper protocol for new species recording occurred fifty years ago is not known. More carefully sifting through the images on BugGuide might actually reveal some answers.

  • Hi J. Hopkins:

    Please don’t underestimate yourself, or overestimate some of the ‘expert’ commentary on this site. Although there definitely are a number of experts that contribute regularly to this site, I am by no means one of them, certainly not when it comes to spiders anyway. What I have always liked about this site is that it encourages people to not only appreciate the bugs around them, but to learn more about them, and to pitch in when others have a question. We can all become ‘experts’ if work at it enough. You are the one who saw the spider and it appears you have done your homework, so go with your instincts.

    I should have added P. apacheanus (and perhaps others) to my short list of possibilities, but I missed it and you didn’t. Identifying an insect or a spider from a photo is very often tricky, more so when you have to rely on other photos to do so. That’s why I seldom offer a definitive answer and I always look for several sources before I offer an identification for a creature that falls outside my comfort zone (in this case I probably came off sounding more confident than I really was). I completely agree with the point you make in your last post; the internet is a fantastic resource but mistakes do get made. Regarding your spider, your photo was a bit fuzzy and didn’t show all the features that could be relevant to making an identification (one photo seldom does), so you may never get an absolute answer unless you get some more photos or get a opportunity to examine a specimen more closely. In the meantime, go with your answer, it sounds pretty good to me. I really appreciate your effort and follow-up comments – my own education continues. Regards. K

  • My son and I just found a spider EXACTLY like the one posted above. It was climbing up the side of my house (outside). We are happy to know that it is not dangerous. We live in Kansas, so they are not just found in OK. We lost it before we could take a picture to send in.

  • My son found one of these this afternoon 🙂 They’re so cute! I plan on trying to get a photo tomorrow. Thanks for all the great information!

  • I think this is a Gray Wall Jumper (Menemerus bivittatus). I just found a zillion of these little guys in a west Florida park.

  • Dorsal markings clearly show it’s audax. Koch provides probably the easiest treatment of the markings. Audax, otiossus, and Regina can be differentiated by the shape of the dorsal markings.

    I have the same in Hartford, CT.

  • Found one of these spiders on my porch yesterday. Was trying to identify. I am located south east Texas and have not been able to confirm identity of spider. I did take several pics but because he/she had gotten swept up with broom, wasn’t as vibrant from the sand/dust AND kept jumping around, which resulted in poor quality pic.

  • I just found one of these spiders in the casing of our patio door. Have not seen one like it before, and we’ve lived in Boulder, Colorado, for over 40 years. I didn’t kill it … I encouraged it to run down the casing, but it didn’t venture out onto the patio … it scurried under a part of the casing where, I assume, it felt protected. It matches that photo on this page exactly.

  • I just saw one of these amazing spiders after bringing home some scrap lumber in the Flint Hills KS. The wood had been sitting there long enough to gather some huge old webs. Didn’t squish this one! It ran along (with some ushering and probably scared out of it’s wits!) to the closest hiding spot. Looks *exactly* like the picture. I’ve never seen one like it before- Unfortunately, I didn’t think to take pics! Didn’t get a chance to see it jumping though

  • I live in New Britain ct and I just found one in my home I was very curious what kind of spider it was so I looked it up I found that they do jump on flat surface it was quite horrifying what frankly didn’t know we had spiders like that in Connecticut.

  • I killed this in Georgia

  • Just found one of these in my home home and thought it was poisonous. My dad killed it. :'(

  • this same one has been eyeballing me from my dash and steering wheel. I do not do 8 leggers well at all. It was stalking me. Has now met its demise. It looked like your picture

  • Came and visited my Mother in Benson,Az. And she said this thing was Eye following her everywhere she walked in the surrounding of the front porch.
