Do Spiders Really Feel Pain? (Sensing Injuries)


There’s a lot of debate surrounding the topic of spiders and whether or not they feel pain. Some people believe spiders do feel pain, while others maintain they don’t feel anything. So, which is it?

Well, according to science spiders don’t feel pain! This is because they have a very different type of nervous system compared to us humans.

However, while they may not be able to feel pain in the way that we do! this doesn’t mean that spiders don’t know something is wrong when they are hurt or injured.

To explain this in more detail let’s take a look at the spider’s nervous system!

Spiders Nervous System

The spider’s nervous system is concentrated in the “cephalothorax” and is made of two body parts the head and thorax. This means they can feel touch and pressure all over their body, not just in one specific area!

The spider’s nervous system consists of a (ganglion) located under the esophagus and below and behind the brain. This mass of nervous tissue (ganglia) is fused with a ganglion, which helps to control the spider’s movements.

The spider’s nervous system is very sensitive, allowing them to respond quickly to changes in its environment. For example, they can detect the vibrations of prey approaching and react accordingly.

Additionally, spiders have excellent vision, which allows them to see their prey even when it is far away. Their eyes are also very sensitive to changes in light, allowing them to see in low-light conditions. Together, these adaptations allow spiders to be successful predators.

Do Spiders Feel Pain When Squished?

So we know spiders don’t feel pain like us humans, but, what if one was accidentally squished? Well, while there is still some debate on this subject, the answer is no! spiders do not feel pain when squished.

The reason for this is that pain is a neurological response that requires time to process. In order for an animal “or spider” to feel pain, its brain needs to first receive and interpret signals from the affected body part.

But, because the traumatic event happens so quickly that there is no time for this neurological response to take place.

Do Spiders Feel Pain When Sprayed?

Many people have the problem of having uninvited guests in their house, “in this case spiders” so they often resort to using a toxic spray to get rid of them. But do these spiders feel anything when sprayed?

Well, Just like with squishing, we do not know for sure if spiders feel pain when they are sprayed, however, it’s highly unlikely they do!

Again their nervous systems are simply not as developed as ours and they lack the necessary receptors for pain.

Do Spiders Feel Pain When They Fall?

Ok, so we’ve all seen it when a spider is struggling to climb up a wall or piece of furniture and then, all of the sudden, it falls to the ground which looks incredibly painful but do they feel it?

When a spider falls, it is likely that they do not feel pain. However, as before, they may be able to sense an injury falling even though they cannot feel pain from it.

How Do Spiders Sense An Injury?

When a spider is harmed, the area around the injury will send out a message to the rest of the spider’s body telling it to be on alert. This response is similar to our own fight-or-flight response and helps the spider know that it needs to take action in order to protect itself.

Although spiders don’t feel pain in the same way that we do, this does not mean that they can’t feel any discomfort or sense when they are injured.

When spiders sense when something is wrong they will take steps to try and remedy the situation. For example, if a spider loses a leg, it will often regrow the lost appendage this typically happens during its molting cycle, when the spider sheds its exoskeleton and grows a new one.

However, this process is not perfect, and the new leg may be shorter or have a different shape than the original. However, it is still an amazing feat of regeneration that allows the spider to continue on with its life despite sustaining an injury.

What Should You Do If You See An Injured Spider?

Unfortunately, sometimes spiders get injured, usually through no fault of their own. If you do see an injured spider, the best thing to do is to leave it alone. In most cases, the spider will simply want to be left alone to recover from its injuries.

However, there are a few things you can do to help the spider heal:

  • If you are concerned for the spider’s well-being you can simply move it to a safe place away from any potential predators. Once the spider is in a safe environment, it should be able to heal and resume its normal activities.
  • Offer the spider some food and water. Small insects or even drops of honey water can help the spider regain its strength and hydrate its body.
  • Observe the spider for any signs of infection or disease. If you see any redness, swelling, or the spiders have not moved on after a day or two you should contact your vet as the spider could have more serious injuries.


While the debate over whether or not spiders feel pain is unlikely to be resolved anytime soon, the evidence suggests that they don’t! As you have just read in this article.
