Reasons
Historically, spider in Europe were thought to carry disease. During the 14th century, the Black Plague swept across Europe killing millions of people. People believed that any food a spider had touched was infected. Spiders were believed to bring death. But actually, the plague was spread by infected rats-not spider. In Western countries, nine out of 10 people who suffer from arachnophobia are women. Of course, the tendency of Hollywood to make cheap science fiction movies about giant spider does not help those with arachnophobia.
