Historically, spiders in Europe were thought to carry diseases. During the 14th century, the Black Plague swept across Europe killing millions of people. People believed that any food that a spider had touched. was infected. Spiders were believed to bring death. But actually, the plague .,was spread by infected rats-not spiders.
