Yes, jumping spiders can bite. Although jumping spiders are small, they have fangs that can pierce the skin of humans.

Unlike other spiders, jumping spiders do not bite often.

In reality, jumping spider bites are scarce.

Jumping spiders are shy. When they feel threatened, they will likely run or jump away.

If a jumping spider bites you, you likely forced the jumping spider into a position where it feels it must resort to biting.

This might happen if you are trying to play or pick up a jumping spider. Likewise, if you are trying to remove a jumping spider from your home and you’ve cornered it, it can try to bite you.

Avoid putting jumping spiders in a position where they feel threatened and can’t escape. This is the most common scenario that causes jumping spiders to bite.

There is a common misconception that jumping spiders enjoyed being held or touched.

The truth is that jumping spiders can get accustomed to being held or touched.

To reach this point, it requires patience and practice. Jumping spiders need to feel safe if you want them to travel across your hands freely.

If a jumping spider bites you, you will experience similar symptoms to a mosquito or other spider bite.

The bite will cause redness, itching, and the bite may cause swelling and stinging in worse cases.

Are Jumping Spiders Poisonous?

Since we know that jumping spiders can bite, you are probably wondering if they are venomous.

Before we begin, there is a crucial difference between animals being venomous and poisonous.

Animals or insects that are venomous deliver their poison by biting, injecting, or harming other animals or insects.

Venomous animals include snakes and spiders because they deliver their poison by biting their target.

Poisonous animals and insects deliver their poison through contact, most commonly when another insect or animal tries to attack it.

Poisonous animals include poison frogs; these frogs secrete the poison through their skin, protecting them from any predators that try to attack them.

With that said, jumping spiders are venomous.

It is important to note that the venom they do have is harmless to humans.

They do not deliver enough venom to cause severe harm or death to humans.

Their venom is highly effective against animals around their size.

If a jumping spider bites you, mild symptoms should occur.

This includes minor swelling, redness, and itching. If you experience more severe symptoms after being bitten by a jumping spider, you should seek medical attention.

Trapping the spider and taking it with you to the hospital can help doctors treat the bite if there are complications.

How To Identify a Jumping Spider?

There are about 4000 different known types of jumping spiders in the world. This makes it hard to offer a single color wave that will identify jumping spiders.

There are a few key characteristics that help distinguish jumping spiders from other spiders.

The first is their size; they are only around ⅛ – ¾” large. Compared to other spiders, this is relatively small. They are even smaller when they first hatch.

The other thing that is unique to jumping spiders is that they typically have thick hairs covering their bodies. In many cases, a portion of these hairs will be brightly colored or iridescent.

Another key characteristic is that their front legs are usually thicker and longer than the six other legs across their bodies.

The signature characteristic of the jumping spider is its jittery fast movements and ability to jump. Jumping spiders can jump around six times their body length.

Why Do Jumping Spiders Bite?

Jumping spiders will flea when they are frightened. This means they only resort to biting when they do not have the option to flea.

If jumping spiders is frightened but can not flea, it will resort to its final option to bite.

This is common if you try to pick up a jumping spider or accidentally smash or place a body part over it.

These situations do not allow the jumping spider to react, and thus it will resort to biting.

Bites from a jumping spider are uncommon, and if you are bitten, you will typically have seen it or know immediately.

Since jumping spiders are quite shy, it’s quite challenging to get close to a jumping spider without making an effort yourself to approach it very quietly and slowly.

Jumping spiders have a great vision, which means they will see you approaching, and in most cases, this allows them to run or jump away before they have to bite you.

When You Should Seek Medical Attention?

You should seek medical attention if you experience excessive pain or other symptoms such as nausea or headache.

These are signs that you may be having an allergic reaction to the jumping spider bite. You should also seek medical attention if you experience abnormal swelling or redness around the bite.

The jumping spider bite should have similar symptoms as a normal mosquito or spider bite for most people.

You should seek medical attention if you are experiencing anything beyond the normal reaction of a spider bite or mosquito bite.

Do Jumping Spiders Bites Hurt?

Jumping spider’s bites do not cause excessive pain. Their bites can cause mild or a slight stinging sensation for a short period.

In most cases, this pain is short-lived, and you won’t feel it for very long after that.

If you experience excess pain, seek medical attention immediately.

It’s possible that you are allergic to jumping spider bites or that the spider that bit you is not a jumping spider.

If possible, I recommend that you take the spider with you to the hospital so that they can identify the type of spider.

This can significantly help with treatment and help determine the severity of the pain.
Sometimes jumping spiders are confused with black widow spiders due to their dark black abdomens.

Taking the spider to the hospital with you will ensure that you are not making a mistake such as this.

Are Jumping Spiders Aggressive?

Jumping spiders are not aggressive. Compared to most spiders, jumping spiders are actually quite shy.

When they feel threatened, jumping spiders will run or jump away.

In fact, jumping spiders are also quite docile. Many people enjoy keeping them as pets for this reason.

With some patience you can get jumping spiders accustomed to being held and touched.

It is important that you don’t force jumping spiders to jump on your hand. They need to do this willingly with encouragement.

Even a jumping spiders that is accustomed to human interaction may bite if you try to corner it and force it on to your hand.

Can Jumping Spiders Kill You?

Jumping spiders can not kill you. While they do produce venom, it is not enough to cause significant damage to humans.

They can kill small insects and other small animals with their venom. Jumping spiders are quite voracious spiders that will attack and eat anything that they can takedown.

For this reason, they are effective at controlling pests inside gardens.

They commonly eat flies, most worms, crickets, aphids, and even cockroaches.

Unlike other spiders that use their web to catch their prey, jumping spiders attack their prey by jumping on them and attacking them.

Their jumping ability, combined with their web, allows them to attack unsuspecting prey with pinpoint precision and effectiveness.

Why Do Jumping Spiders Look At You?

Jumping spiders are hunters. Unlike other spiders, they track and pounce on their prey that waits for their prey to fall victim to their web.

This makes jumping spiders on the constant prowl for new prey. When you see a jumping spider looking at you, it tries to determine if you are suitable prey. It will then determine how far you are and whether you are a treat or not.

So if a jumping spider is looking at you, it is trying to determine if it can eat you.

Jumping spiders have exceptional eyesight that they use to do this. They use the eye on the outside to track general movements of objects away from or towards them.

They use their large eye for a detailed assessment of how far an object is, how large it is, and its looks.

Why Are Jumping Spiders So Smart?

Jumping spiders have become so smart due to their hunting, tracking, and escape abilities.

Since they do not use the web to capture their prey, they have developed sophisticated techniques to catch their prey over time.

While their brain is small, research has shown that jumping spiders are very smart and analytical creatures.

Certain jumping spiders are known to find hidden prey by visualizing their location after they have lost sight. They are also known for planning and attempting different paths to attack certain prey.

The jumping abilities of spiders have also been well research. They tought a jumping spider to adjust its jump by adjusting the height, angle, and distance that the spider needs to jump.

Even doing this, the spider can calculate and adjust its jump to land correctly on a platform without falling.

How Long Do Jumping Spiders Live For?

Jumping spiders are short-lived insects. They typically live between 6 months and one and a half years.

Certain jumping spiders can survive up to two or three years.

Overall, jumping spiders do not live very long, and you can expect most to die within one year. If you do have one as a pet, you will need to replace it at some point.

In captivity, and if they are well cared for, some jumping spiders can survive upwards of three years.

How To Remove Jumping Spiders?


Jumping spiders typically enter your home through entry points in your home. This can be through cracks, open windows, broken screens, cracked door or window sills, or even under the door.

The best way to get rid of jumping spiders inside your home is to seal up and cracks or crevices that you might see.

Since jumping spiders are tiny, even holes or cracks that might seem like something can act as an open door for jumping spiders to enter your home.

I recommend inspecting your house and sealing up, and entry points around your home.

The best way to do this is by using caulk to fill up any of these cracks. You can also fix screens on windows or doors.

Another great way to keep jumping spiders out is by installing or reinstalling new door sweeps, door sills, and window sills.

By weatherproofing your home, you make it very hard for jumping spiders to get in unless you are leaving windows or doors wide open.

Other than that, if all entry points are closed, jumping spiders should not be able to enter your home.

As additional protection, you can apply a barrier treatment around your home’s base and entry points.

This would be an insecticide such as Bifen I/T that has a residual effect. These types of treatments typically last around three months.

Any insect that crawls of the surface where the insecticide was applied will slowly die.

Any insect that crawl of the surface where the insecticide was applied will slowly die.


If you have jumping spiders outside your home, it might be worth keeping them there and not trying to get rid of them.

The reality is that they provide much more benefits than they do disadvantages.

For example, they do not bite unless you force them to, and they do not leave large webs all-around your property.

On the other hand, they are great at controlling garden pests, yet they don’t damage or disturb your garden on your yard in any way.

If you intend to get rid of jumping spiders from outside, the best way to go is to get rid of jumping spiders to apply an insecticide around your home.

You can use a residual insecticide three feet on the floor around your home and three feet of all the walls around your house.

This will give you a solid barrier to kill any insects that decide to approach your home.

If you want to get rid of jumping spiders in your garden or other areas of your lawn with more delicate flowers or plants, you will need to use a natural alternative to killing jumping spiders.

You can do this by applying DE in liquid form to your entire garden. After drying, this will kill any spiders that it comes into contact with.

It is inexpensive, non-toxic, and 100% all-natural. This is a great way to get rid of jumping spiders and many other insects without spraying toxic chemicals all over your yard.

It’s important to note that DE is only useful once it dries. You will not see results until several days after the DE has dried, and it has had time to take effect on any insects that it came in contact with.

How Worried Should I Be About Jumping Spiders?

If you have jumping spiders, the reality is that you should not be worried.

Jumping spiders provide more benefits than any disadvantages or dangers they may cause.

The main concerns that spiders cause are not a concern for jumping spiders:

  • Jumping spiders generally do not bite unless provoked
  • Bites are harmless even if they do happen
  • They do not create webs
  • They have a short lifespan

While they don’t provide many disadvantages, they are great spiders to have in your garden to their voracious eating habits.

They are a great way to control any pest issues you may be having in your garden.

Some gardeners promote or enhance their jumping spider population in their garden to keep their garden free of destructive pests.
