Bugs

Althought not considered a "demon" something controlled bugs to attack several people in the Indiana area in 2006. The first death was that of construction worker who fell down a man hole and was eaten alive by the bugs down there, the second death happened to a realtor by the name of Linda when she was attacked by a spider. When the Winchesters investigate, they find a jar of bugs belonging to a little boy. Dean and Sam talk to the little boy who shows them where he collects them in a spot in the forest. Soon, they help the little boy's parents when their house gets infested with the creatures. They seal off all openings to the house and Dean uses inflammable bug spray to keep them at bay. The next day, the family decides to move.
