Do Jumping Spiders Bite?

Yes. Although small, Jumping spiders can bite. They have fangs that can pierce the human skin.

That said, jumping spiders rarely bite. These spiders are generally shy and will likely run or jump away rather than bite you.

If a jumping spider bites you, it usually means it’s threatened.

This might happen if you’re trying to play or pick up a jumping spider. Likewise, they may bite if you try to capture them

To avoid getting bitten, don’t put jumping spiders in a position where they feel threatened and can’t escape.

Jumping spiders are not poisonous, but they are venomous.

That said, jumping spiders are harmless to humans. Their venom, however, is highly effective against animals around their size.

Some example of venomous animals include snakes and spiders.

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

An example of a poisonous animals are poison frogs. Poison frogs secrete the poison through their skin, protecting them from any predators that try to attack them.

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

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.

But there are a few key characteristics that help distinguish jumping spiders from other spiders:

Body and Color: Jumping spiders have thick hairs covering their bodies. In many cases, a portion of these hairs will be brightly colored or iridescent.

Legs: Their front legs are usually thicker and longer than the six other legs across their bodies.

Behavior: 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.

But they are more likely to flee than bite. They usually only bite if they think they cannot flee.

This is common if you try to pick up a jumping spider.

Jumping spiders have a great vision, which means they will see you approaching.

In most cases, this allows them to run or jump away before they have to bite you.

When You Should Seek Medical Attention?

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

Thus, you should seek medical attention if you are experiencing anything beyond the normal reaction of a mosquito bite.

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.

Do Jumping Spiders Bites Hurt?

Jumping spider 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 the incident.

Jumping spider bites don’t cause excessive pain.

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. 

Doing so can help with treatment and help determine the severity of the pain.

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

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.

That said, you mustn’t force jumping spiders to jump on your hand.

They need to do this willingly with encouragement.

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

Can Jumping Spiders Kill You?

No. Jumping spiders can’t 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.

These spiders are quite voracious spiders that will eat anything that they can takedown. They commonly feed on flies, most worms, crickets, aphids, and even cockroaches.

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

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

With these spiders’ jumping ability and web, they can easily attack unsuspecting prey with pinpoint precision and effectiveness.

They use their large eye for a detailed assessment of how far an object is, how large it is, and whether it’s a suitable prey.

Why Are Jumping Spiders So Smart?

Jumping spiders are hunters. So they have to be good at tracking, being sneaky and escaping.

They do not use the web to capture their prey. Instead they pounce on them. Their hunting needs have allowed them to develop 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.

To prevent them from entering your home inside your home is to seal up and cracks or crevices that you might see.

Caulk up any cracks and crevices on your doors, windows and walls. Fix any holes in your door and window screens.

Install or reinstall a new door sweeps, door sills, and window sills.

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 you apply the insecticide will die.

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.

You can also use a natural alternative such as Diatomaceous Earth.

DE is inexpensive, non-toxic, and 100% all-natural.

To do this, mix 1/2 cup of DE with 1 cup of water and put the mixture in a spray bottle. Spray around 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.
