Arachnophobia is a form of a specific phobia that involves the fear of arachnids such as spiders and scorpions. While most people are usually not very fond of insects, a specific phobia of spiders can affect one’s functioning to a significant degree.

What Is Arachnophobia?

Arachnophobia comes from the Greek word for spider, which is “arachne,” and the Greek word for fear, “phobos”.

Also known as spider phobia, arachnophobia is defined as an acute, abnormal and persistent fear of spiders. Individuals with this phobia experience extreme anxiety, even though they may apprehend that the danger of facing a spider and getting harmed is minimal or nonexistent. The fear can be triggered even on witnessing images of spiders or simply at the mention of them.

A person with this condition may avoid walking barefoot and happen to be alert, especially while taking showers or while getting in and out of bed. Sometimes, the sufferer might take extreme steps to avoid spiders.

Studies 1 show that the fear response is associated more with the movement patterns of the arachnids than their physical appearance. Just like any other phobia, the fear of spiders can weaken you mentally and physically while also interfering with your daily functioning.

It can also lead to an increased fear of other animals that are generally feared or evoke disgust 2. However, once it has been identified, one can get help from experts and eventually go on to live a normal life.

Case Example

When she was around 6 years old, Risha listened to a story by her grandmother in which a man got bitten by a spider and subsequently died.

A few months later, when she was taken to a zoo, she started experiencing nausea as soon as they told her that there was a section nearby where they kept spiders. Before she even saw one with her eyes, Risha fainted. Since then, she had been absolutely terrified of spiders.

She couldn’t even look at pictures or emoticons of spiders without feeling dizzy and experiencing increased breathing and heartbeat rates. Anything that even resembled them would make her extremely uneasy.

Her fear made her wary of public washrooms, nooks and corners, and spaces where there might be spiders. She would mostly avoid outdoor activities and going on trips out of the station due to the possibility of encountering a spider.

Case Analysis

It is clear from Risha’s symptoms that she was experiencing extreme discomfort and suffering from nausea, an increase in heartbeat, fast breathing, dizziness, and loss of consciousness in the actual or imagined presence of spiders. These symptoms suggest that Risha had a specific phobia of spiders or arachnophobia.

How Common Is Arachnophobia?

While specific phobias are quite common, arachnophobia in particular affects around 3.5 to 6.1 per cent of the global population 3. Research 4 indicates that women are more prone to develop spider phobia than men.

What Is The Psychology Behind Arachnophobia?

If you are afraid of spiders, that does not necessarily mean you are suffering from arachnophobia. Phobias are a condition of extreme fear that causes a form of paralysis and impairment in a person’s quality of life.

The following are traits of a specific phobia, as per the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5):

1. Extreme & Persistent Fear

If you hold a normal dislike or fear towards a spider, you are most likely to give an expression of disgust or climb onto some furniture while yelling for help.

However, if you are suffering from spider phobia, you will feel extreme anxiety or enter a state of panic, both with the presence and the anticipation or potential presence of spiders.

2. Immediate Fear Response

If you have arachnophobia, the thought of a spider in the near vicinity is just as terrifying as a spider in your hair. When you see a spider or even assume that you might see one, your anxiety and panic are likely to be immediate.

However, in some arachnophobes, the presence or the assumed presence of a spider does not always provoke a panic attack. Such individuals are more likely to experience severe fear if they feel trapped with the spider in the same room or house.

3. Avoidance

A person with arachnophobia will avoid a spider at any cost. You might end up cleaning your house for hours or sleeping at your friend’s place if you see a spider in your house.

You’ll also avoid the outdoors or the basement of your house as you fear that you may run into one. Such actions may interfere with various aspects of your life, like your relationship, work, and how you spend your time.

Symptoms Of Arachnophobia

Here are the most common physical and behavioral symptoms 5 of this condition –

1. Physical Symptoms

The most observed physical symptoms associated with this phobia are:

  • Feeling a sense of dizziness or lightheadedness
  • Suffering from an upset stomach
  • Feeling nausea
  • Sweating profusely while shaking or trembling with fear
  • Experiencing shortness of breath
  • Increased heart rate
  • Fainting out of fear

2. Behavioral Symptoms

Apart from the physical symptoms, a person with arachnophobia may also display behavioral symptoms such as:

  • Unexplainable alertness connected to the spiders along with the obsession of checking the presence of spiders before going anywhere.
  • Avoiding places where spiders can be usually found such as caves, forests, museums, or old buildings.
  • Avoiding activities such as hiking and camping trips. Avoiding places connected to a negative past experience with spiders. Difficulty with concentration and functioning at work or in personal relationships
  • Avoiding social gatherings.

What Causes Arachnophobia?

Although the exact causes of onset are still unclear, here are some possible factors that can lead to the development of such specific phobia –

1. Evolutionary Theory

According to evolutionary theory 6, this phobia is a result of a survival method for our ancestors. Since most spiders are poisonous or deadly, a fear of spiders may have made humans more likely to survive and reproduce.

2. Social Theories

Another theory suggests that the fear of spiders in humans is learned. For example, the media or TV shows often describe spiders as scary and potentially dangerous.

Additionally, as a child, if you grow up in an environment where the elders or your parents are scared of spiders, this may lead to learned behavior 7, thereby leading you to develop the same fear.

3. Traumatic Past Experience

Phobias often originate or arise from negative past experiences. Hence, it is likely for one’s fear of spiders to develop as a result of certain negative experiences with such arthropods. . With time, this fear of spiders may develop into arachnophobia.

4. Cultural Background

Some experts also theorize that the fear of spiders is inspired by one’s cultural background. For example, in certain regions of Africa, large spiders are feared. However, in South Africa, where spiders are eaten, people may feel unafraid of them.

Arachnophobia Diagnosis

Arachnophobia does not usually require a formal diagnosis from a doctor as phobias are more or less often self-diagnosable. However, it is a wiser decision to seek professional help to enable you to work through your spider phobia.

Consider asking yourself a few questions that may help you to understand whether the fear is interfering with your day-to-day activities.

  • Is the fear of spiders making it difficult for you to go outdoors?
  • Is it getting in the way of your work?
  • Is it affecting your social life?
  • Is it stopping you from spending time with your loved ones?
  • Does the fear of spiders keep you awake at night?
  • Are you not able to stop thinking about spiders?

If the answer to these questions is ”yes”, you may consider seeing a psychotherapist. However, to diagnose the condition as arachnophobia, the symptoms should be occurring for more than six months and it should be intense enough to disrupt your daily life activities and needs.

How To Treat Fear Of Spiders

Specific phobias such as arachnophobia are relatively easier to treat when compared to complex phobias. Chances are high that with age, symptoms of arachnophobia may decrease. The arachnophobia treatment may be in the form of therapy or medication, depending on the severity of your symptoms and preferences.

Here are the most common and effective treatment approaches for this condition –

1. Therapy

Studies 8 have found that behavioral therapy-based treatment can prove effective for treating spider phobia, especially in children. Here are some therapy approaches widely recommended by healthcare professionals –

A. Exposure therapy

Exposure therapy is a process wherein the patient is directly exposed to their phobia, in this case, a spider. A study 9 said that making the person watch arachnid or insect-themed superhero movies, like “Spider-Man or Ant-Man” can help reduce phobic symptoms.

A type of exposure therapy is called flooding. Here, the person is exposed to their phobia in full intensity by the therapist in an attempt to decrease their anxiety.

B. Hypnotherapy

Hypnosis can also help a person overcome arachnophobia. Hypnotherapy 10 uses relaxation techniques to provoke a state of focused attention. The therapist will then use techniques and guided representation to help reduce phobia. However, there is a lack of scientific evidence to support the effectiveness of this treatment.

C. Cognitive Behavioral Therapy

In cognitive-behavioral therapy (CBT), the therapist works with the patient to help them overcome their fearful thoughts. CBT techniques are considered to be one of the most effective treatments for specific phobias, as validated by a recent 2021 study 4.

  • Sedatives
  • Supplements for anxiety
