If you have found a huntsman spider in your home, you need to know how venomous it is. Read on to find out the answer.


Often known as banana spiders or giant crab spiders, huntsman spiders are some of the largest in the world. There are thousands of subspecies of this arachnid, but the giant huntsman spider is the most well-known because of its size.

How Poisonous Is a Huntsman Spider?

Huntsman spiders are not poisonous (like some other species of arachnids). They are venomous. This means that if you touch them, you are not going to be affected, but if they bite you, there are going to be some effects of that.

All spiders, including the huntsman spider, have venom. However, the venom of the huntsman spider is not life-threatening unless you develop an allergic reaction to it. Allergic reactions to huntsman spider bites are not common.

That said, it is best to avoid a huntsman spider and let it be. Don’t go digging around loose bark while gardening, or try to pick up a huntsman spider if you find one. They will perceive you as a threat and can bite.

Do Huntsman Spiders Bite and Are They Dangerous?

Despite their name, huntsman spiders are not dangerous spiders. They prefer to take cover instead of trying to bite a human.

However, in some circumstances, huntsman spiders might bite, especially if it is a female spider that is protecting her eggs. In such situations, a huntsman spider will bite when provoked.

When a huntsman spider bites, you will feel some pain for a while. There will be localized swelling as well. You might get a headache or feel nauseous. In some cases, the bite may result in heart palpitations of reduced pulse rate for some time.

The bite can lead to inflammation as the venom spreads. When that happens, the doctor will prescribe nonsteroidal anti-inflammatory drugs or NSAIDs for relief.

How To Prevent Huntsman Spiders From Entering Your Home?

Huntsman spiders are found in Australia, New Zealand, South America, and also in certain subtropical areas in the United States. While they mostly reside in the wild, sometimes, these spiders can come indoors.

It is very common for people in Australia and New Zealand to find huntsman spiders inside their cars and homes.

Since they are not really dangerous, some have even kept these Australian huntsman spiders as pets or natural pest removers! But it is perfectly understandable if you don’t want such a houseguest.

If you have cockroaches, mites, or other small lizards indoors, huntsman spiders might enter your home to feast on them. A pest control professional will be able to control these for you.

You should also check for possible entry points and seal them up. Make sure you repaid all cracks or gaps in windows and screen doors.

Frequently Asked Questions

Is it safe to pick up a Huntsman?

While huntsman spiders usually don’t attack, they are still venomous spiders. Therefore, it is best not to pick up a huntsman spider with your bare hands. If you are not able to handle them properly, they will bite.

Do huntsman spiders jump at you?

Huntsman spiders don’t jump deliberately. In fact, they tend to “fall,” and it looks like they are jumping. This is because they have a crab-like physique, which makes it look like they are jumping instead of falling.

If you find one “jumping” down from your car’s sun visors, know that they are just trying to run away and hide.

What do huntsman spiders hate?

Huntsman spiders are not big fans of strong odors. These large spiders hate citrus scents such as the scent of eucalyptus and peppermint. So if you spray these scents or put a few drops of natural oils around the house, that will keep them away.

What do you do if a huntsman spider is in your house?

If you find a huntsman spider in your house, slowly place a container on top and push in paper from underneath. Then you can throw it out. But be sure that it is a huntsman spider first.

People often mistake brown recluse spiders for huntsman spiders, and those are far deadlier than huntsman spiders.

Wrap Up

Huntsman spiders look scary, but fortunately, they don’t have a lethal bite. The venom is not lethal, and you may not even need medical attention.

Also, a huntsman spider will not attack you unless provoked. So there isn’t much to worry about. Thank you for taking the time to read, and we hope you found the answers you were looking for.

Letter 1 – Golden Huntsman Spider


Wolf Spider or Desert Recluse
I need your help. It is a big spider about 3’ in diameter. Comes out every night to hunt to find prey. Is it dangerous?
Thanks for your help!
Age 8

Hi Michael,
Your letter came at a perfect time. Another person just described this spider but had no photo, so I will forward it. This is a Golden Huntsman Spider, Olios fasciculatus. It lives in shady woodlands, thickets and homes in New Mexico and Utah, west to California. It builds no web but wanders slowly in search of prey at night. It is not dangerous.

Letter 2 – Golden Huntsman Spider


I live in the desert, and I found a spider by the name Golden Huntsmen. I was told it was not deadly, but it was really ugly. Could you please give me some info about it.

Hi James,
The Golden Huntsman Spider is Olios fasciculatus, one of the Giant Crab Spiders of the Family Sparassidae. They are, as you know, large spiders named for their crablike legs. They are mostly tropical but found in Florida and the Southwest as well. The Golden Huntsman Spider does not build a web, but wanders in slow search of prey. The female carries her egg sac in her jaws until the spiderlings emerge. It is found in shady woodlands and thickets from New Mexico and Utah west to California.

Letter 3 – Golden Huntsman Spider


Found this beautiful Huntsman at my parents house in southern Arizona. Thought you might love taking a look at it. It stayed on the table for about 4 days before moving on to better hunting. Enjoy.
Andy Marshall

Hi Andy,
Your image of a Golden Hunstman Spider, Olios fasciculatus, is exquisite.

Letter 4 – Golden Huntsman Spider


A Golden Huntsman, I presume? It was haunting the Ladies Room of our campground in Arches National Park, UT. Anyway, I think I got great contrast with the white painted wall & thought you may be able to use it. Let me know if was not correct in my ID.
Robert M.

Hi Robert,
You are correct. This is a Golden Huntsman Spider. We understand that Huntsman Spiders often haunt dark damp places, but why were you haunting the woman’s restroom, and with a camera no less?

Letter 5 – Palo Verde Root Borer and Golden Huntsman Spider


Palo Verde Borer Beetle & Golden Huntsman Spider
Great bugsite! The beetle submission on 7/2/2004 [Derobrachus geminatus: Due for a new name.] caught my attention. While outside in my yard on a hot July 8th, 2005 night at 11:22 p.m., in Paradise Valley, Arizona, I encountered a magnificent bug, easily 4 or 5 inches in length! I believe this too is an example of the Palo Verde Borer Beetle, currently known as Derobrachus geminatus. I don’t think my photograph is better than the lovely one you have posted, but it does offer a different viewing angle. These beetles lumbered around my property late at night, for about a week. I suspect this was prime mating time. Since the entomology course I took in college covered only insects, I found myself at a loss for identifying the eight-legged creature in the second attached photograph. I found this spider on May 26th, 2005 at 2:20 p.m. on a warm, sunny afternoon. It was motionless, on the ceiling of my porch. When I initially checked your site I couldn’t find a comparable spider. However, it looks like someone submitted a picture of the same spider on 7/14/05! Now I know it was the Golden Huntsman Spider, Olios fasciculatus. Just thought I’d share my picture with you.

Hi Krista,
Thank you so much for your submission. We especially love the Golden Huntsman Spider image.

Letter 6 – Huntsman Spider from Indonesia


Subject: Spider in Flores, Indonesia
Location: Labuanbajo, Flores, Indonesia
February 4, 2015 6:24 am
Found this spider in my house. Very fast and about 7 centimeter diameter (including legs). Do you know what it is?
Signature: Chris

Huntsman Spider
Huntsman Spider

Hi Chris,
This is a Huntsman Spider or Giant Crab Spider,
Heteropoda venatoria, and it is considered harmless to humans.  This species is also called a Banana Spider because they were often imported with bunches of banana and they have become established in warm coastal cities throughout the world because of global shipments of bananas.  Huntsman Spiders do not build a web, but they hunt their prey, often Cockroaches, at night, so they can be considered beneficial.

Wow super quick. Thanks a ton!

Letter 7 – Huntsman Spider painted at factory in China


Subject:  Painted carnage!
Geographic location of the bug:  Irrelevant
Date: 03/28/2018
Time: 07:42 PM EDT
Your letter to the bugman:  Hi, Bugman! I work at a retail store in South Dakota, but much of our merchandise is made in China. I think this poor creature must have been painted into this canister at the factory in China. Can you identify, despite his ‘blue mood’? Hard to say with legs folded under, but I’d put the length of each limb at 3″+. For scale, the floor tiles are 12″x12″.
How you want your letter signed:  Josh M

Huntsman Spider painted Blue

Dear Josh,
We agree with your assessment that this Spider must have been painted at the factory.  We believe this is a male Giant Huntsman Spider,
Heteropoda venatoria, a species that has been introduced to many parts of the world because of banana shipments.  This would have made a good April Fool’s posting were it not for real.

  1. Hmm it appears like your website ate my first comment (it was super long) so I
    guess I’ll just sum it up what I had written and say, I’m thoroughly enjoying your
    blog. I too am an aspiring blog blogger but I’m still new to the whole thing. Do you have any suggestions for beginner blog writers? I’d definitely appreciate it.

    • OOPS. We were preparing a counter-statement when we realized you were correcting our language and not our intent. We maintain this Huntsman Spider is relatively harmless to humans. Thanks for catching our error. We will nonetheless post the research we conducted to support that statement. According to Texas Invasive Species Institute: “Ecological Threat: The huntsman spider is not poisonous, but if handled aggressively it will issue a painful bite. This spider does not use a web to capture prey and is ideal for management of cockroaches and similar indoor pests.” According to BugGuide: “Can be swift and sometimes aggressive but not considered dangerously venomous to humans. May bite in self-defense if roughly handled; mildly painful bite (can be likened to a bee sting if spider injects venom).” According to the University of Florida Extension site: “It is not a dangerous spider, but a locally painful bite can be delivered to any human who carelessly handles a huntsman spider.” According to the Natural History Museum site: “The venom causes mild symptoms in humans (Bucherl, 1971). “
