Samuel says that arachne are a type of monster that haven't been seen outside Crete in 2,000 years. There is little lore on them, or how to kill them. Samuel suggests they "just go at it until something sticks".
Samuel and Sam hunted an arachne that was taking men in thirties, and poisoning them in order to turn them into arachne. They used the local Sheriff Roy Dobbs as bait, and followed her to her lair. Sam kills her by decapitating her. Sam declares the poisoned men beyond help, and shots them all before he and Samuel burn the building. Unknown to them, the arachne survive and escape.
A year later Sheriff Roy Dobbs, now an arachne, lures Sam back by taking woman that Sam slept with, in order to exact revenge. Sam initially remembers nothing of the original hunt, but it returns to him as flashes of memory fragments. Dobbs catches Sam and Dean, but with the help of the Sheriff's wife Brenna Dobbs, they escape, and Sam decapitates him.
Arachne in Lore
Arachne, a Goddess in Greek mythology, was originally a mortal who was an expert weaver taught by the goddess Athena. Arachne was proud of her work, and proclaimed herself better than Athena. After Athena challenges her to see her is the best weaver, Arachne weaves a tapestry showing the Gods in the worst light. Enraged Athean destroys the tapestry, and then Arachne kills herself. Athena is distressed and decides to make an Archne a goddess - but in the form of a spider. The first spider.
