The fear of spiders can be treated by any of the general techniques suggested for specific phobias. The first line of treatment is systematic desensitization – also known as exposure therapy – which was first described by South African psychiatrist Joseph Wolpe. Before engaging in systematic desensitization it is common to train the individual with arachnophobia in relaxation techniques, which will help keep the patient calm. Systematic desensitization can be done in vivo (with live spiders) or by getting the individual to imagine situations involving spiders, then modelling interaction with spiders for the person affected and eventually interacting with real spiders. This technique can be effective in just one session.

Recent advances in technology have enabled the use of virtual or augmented reality spiders for use in therapy. These techniques have proven to be effective.

Arachnophobia is the fear of spiders and other arachnids such as scorpions.

Zoophobia or animal phobia is a class of specific phobias to particular animals, or an irrational fear or even simply dislike of any non-human animals.

Examples of specific zoophobias would be entomophobias, such as that of bees (apiphobia). Fears of spiders (arachnophobia), birds (ornithophobia) and snakes (ophidiophobia) are also common. See the article at -phobia for the list of various phobias. Sigmund Freud mentioned that an animal phobia is one of the most frequent psychoneurotic diseases among children.

Zoophobia is not the sensible fear of dangerous or threatening animals, such as wild dogs (example: wolves, dingoes, and coyotes), big cats, bears or venomous snakes. It is a phobia of animals that causes distress or dysfunction in the individual's everyday life.
