How is Arachnophobia Treated?

Some treatment ways that are effective in controlling arachnophobia in people are:

System Desensitization

This is one of the most common and effective therapies used for controlling fear in a person. The therapist assesses the level of fear of spiders in a person and teaches different relaxation techniques such as breathing control, meditation and muscle control. Then the person is exposed to conditions or imaginations of spiders and taught to use the relaxation techniques at the same time. The major aim is to process reduction of fear and panicking when the person is confronted with situations involving spiders.

Cognitive Behavioral therapy (CBT)

CBT also goes hand in hand with system desensitization. The person receives effective counseling sessions with the therapist who would dig out the roots of the fear in the person, and makes him aware of the situation. The major aim of CBT is to modify all the negative images associated with spiders into more positive and tolerable images.


As in different phobias, medications can also be used alongside other therapies. Anti-anxiety and anti-depressant medicines are generally used to take the symptoms in control depending on the severity of the case.
