What Is A Banana Spider?
The United States banana spider, also known as the Argiope Aurantia, is not poisonous to people.
There are a few different species of spiders in the world which are commonly referred to as banana spiders, and some of them can be quite deadly. That said, the US species of banana spider we are going to focus on today is not deadly at all and in fact considered by most pest control experts to be highly beneficial.
That’s right, we are talking about the United States banana spider commonly referred to as the yellow banana spider, the garden spider, the yellow and black garden spider, the zigzag spider, or the writing spider.
Scientifically known as an Argiope Aurantia, this spider is part of the orb-weaver classification of spiders and is famous for its bright colors, intricate web designs, and large size.
In fact, this banana spider can grow to be between .75 inches and 1.1 inches in length, not including his long legs! This often makes banana spiders appear to be much larger and much more intimidating than they really are. These spiders can also be a multitude of colors including yellow, red, black, silver, orange, and brown.
Adult banana spiders have a short lifespan of only about a month, and females generally eat the male after mating. Still, despite their short lifespan, they reproduce quickly with one female banana spider laying between 300 to 1,400 eggs in her lifetime.
While banana spiders are not a danger to humans, they can bite if provoked and their bite is painful and can cause mild irritation. That said, most experts don’t consider the Argiope Aurantia banana spider to be a nuisance pest and even encourage people to leave these spiders alone so they can assist the environment with natural pest control.
Wondering what these spiders eat? Well, their diet it quite beneficial to us humans and includes:
- Flies
- Mosquitoes
- Wasps
- Stinkbugs
- Beetles
- Butterflies
- Moths
- Bees
- Leaf-footed bugs
- Beetles
- And (Sometimes) Dragonflies
For the most part, banana spiders generally prefer to live outdoors where food sources are abundant. That said, they have been known to make their webs in the eaves of houses and sometimes even inside houses, especially if there is a large enough food source for them there.
Do you have banana spiders entering your home? One or two banana spiders coming inside your home now and then isn’t all that uncommon. But a large infestation of banana spiders inside or on the outside of your home could be the sign of a larger pest issue that may need to be addressed.
With that in mind, let’s talk a bit more about what attracts banana spiders to certain properties.
What Has Attracted The Banana Spider To Your Home Or Yard?
Garden spiders are attracted to tall, sturdy plants where they can build their webs.
Like any living creature, banana spiders are on the hunt for three basic things:
- Food
- Water
- Shelter
While these arachnids most commonly build their nests outdoors where they can fill their bellies with tasty bugs, they can make their way close to your property and build an abundance of strong webs along your deck, porch, eaves, and sometimes even inside your home.
Banana spiders are attracted to different insect food sources like those listed above, but they also seek out good places to build their webs and hide. They prefer taller plants and strong stalks they can attach their webs to. Remember, these guys are pretty big!
Their favorite types of plants include sunflowers and corn stalks, but they’ll make their webs on trees and other sturdy sources as well. This is one of the reasons many banana spiders are so attracted to the eaves and sidings of houses, especially if your house has a good deck with lots of sturdy rails in areas that are protected from the wind and elements.
Banana spiders are also attracted to areas with lots of hiding spots. In gardens, lots of large rocks or debris make for excellent and safe places to run if a predator approaches. In your home, the cracks and crevices, eaves, and dark corners also make excellent hideaways for these spiders.
How To Get Rid Of A Banana Spider – Identifying A Banana Spider Problem
Banana spiders are easy to distinguish by the zigzag webs they weave.
Identifying a banana spider problem around your home isn’t difficult. While these spiders are not social and don’t generally hang around in large numbers, an infestation can start inside your home if the environment is ideal and a female banana spider lays her eggs somewhere inside.
That said, it’s rare to have a banana spider infestation inside and you’ll likely just run into one or two stray banana spiders looking for some shelter or a safe place to stay.
But how do you identify a banana spider problem? Simple. Most banana spider problems are easily spotted because the spiders themselves are so large. Furthermore, a banana spider web is tough to miss and has an interesting design that is unique to this particular Argiope Aurantia species.
If you find a web inside your home, in your garden, or around your property that is large, circular, and has an interesting zigzag pattern down the middle, you’re dealing with the Argiope Aurantia, aka the banana spider.
The below video shows a banana spider in action building his web and creating that amazing zigzag design.

Now, as we mentioned above, having a banana spider outside in your garden is a wonderful thing. But how do you keep them in your garden and deter them from coming into your home?
Great question.
How To Get Rid Of A Banana Spider – Most Popular Methods
If you don’t want banana spiders getting too close to your home, there are some methods you can use to control them.
Since banana spiders are not poisonous and not generally considered nuisance pests, most experts agree it is best to leave them alone if you encounter them outside your home or in your garden. Remember, these spiders can actually help your garden thrive by taking care of annoying pests.
To help control and stop banana spiders from building their webs near your property, in your eaves, porch railings, or sidings, experts suggest following three common methods of prevention to keep them at bay including natural repellents, insecticides, home remedies, and professionals.
All three remedies should be primarily aimed at removing what the banana spider is after, which is a food source and a hospitable living environment.
If you can get rid of the insects the spiders are after and make your home less inviting to them, chances are you won’t be dealing with them at such close range. Let’s learn more about the common methods you can use to control banana spiders.
Natural Products
Natural products are wonderful for those dealing with banana spiders because they are often safe to use around people and pets and won’t hurt the environment. Many natural repellents even prevent spiders from finding your home a habitable place to build their webs due to either smell or sound. This includes the use of essential oil sprays as well as ultrasonic sound repeller products that use sound waves and vibrations to deter pests.
Insecticides
Since the banana spider is not poisonous and is really a beneficial arachnid to have around, you want to try and refrain from killing it. That said, a large number of banana spiders, or any type of spider for that matter, accumulating on your property could be a sign of other pest problems.
If you are dealing with quite a bit of insect activity around your home and believe this has attracted spiders to your property, you may need to use a quality insecticide around the perimeter of your home to help keep these insects and their spider predators away.
That said, insecticides often use harsh chemicals that can be toxic to people, pets and the environment and should be used only as directed and with caution.
Home Remedies
Banana spiders are sensitive insects and are easy to repel using home remedies. Best of all, many of the same home remedies that will repel banana spiders will also repel the insects they may be after on your property. We will talk more about some home remedies and do it yourself pest control options you can use at home to help get rid of the banana spider.
Professionals
Most people don’t need help getting rid of a banana spider on their property as these creatures rarely cause infestations and are generally just hanging around for a feast of bugs. That said, a large amount of spiders on your property could be an indication of another, larger pest problem, as we mentioned above.
If you feel you are constantly battling banana spiders in your home or around your perimeter, you may want to call a professional to find the source of the problem.
But before you call in the experts, let’s take a closer look at the methods you can use to try and control a banana spider problem on your own.

How To Prevent A Future Banana Spider Problem In Your Home Or Yard
Banana spiders are beneficial when they stay outside.
While most banana spiders are seen as beneficial insects and are helpful to gardeners and homeowners looking to keep other, much more annoying pests away, they can become problematic if they get too close for comfort, especially for those with a fear of spiders.
In order to avoid having to deal with the banana spider or other creepy crawlies up close and personal, experts recommend following a few of the below guidelines to keep pests like spiders and other bugs outside where they belong.
Practice Routine Home Maintenance
Spiders enter our homes most often through unsealed entry and exit points. The best way to keep a banana spider out of your home is to caulk cracks and crevices around your home. We also suggest fixing ill-fitted or ripped screens and making sure windows and doors shut securely.
Vacuum and Sweep Often
Insects come into our homes in search of food that we accidentally leave out. Sweeping, vacuuming, and cleaning your surfaces often can help reduce the number of insects coming into your home, which in turn will reduce the chances of having spiders.
Keep Vegetation At Least Three Feet From Your Home’s Perimeter
Another way to keep spiders away from your home is to keep vegetation and plant life at least three feet from your home’s perimeter. Doing this will reduce the chances of having spiders get close enough to your home to want to enter in the first place.
Use Pest Control Methods To Keep Insects That Attract Spiders Out
Last but not least, use a pest control regime all year round to protect your home against pests. Whether you use natural repellents, insecticides, or home remedies, experts suggest using a perimeter protection to keep your home pest free and keep those beneficial banana spiders out in your yard and garden where they belong.
