During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, Bill Weasley taught a group of sixth-years how to defend themselves from Flesh-Eating Slugs by wielding this particular pesticide against the creatures.
In the summer of 1992, Rubeus Hagrid went to Knockturn Alley to buy this product, as Flesh-Eating Slugs were destroying the cabbage crop at Hogwarts School of Witchcraft and Wizardry. While there, he ran into Harry Potter, who had gotten lost after a Floo powder-related accident, and escorted him out of Knockturn Alley back to the Weasley family in Diagon Alley from whom he had become separated.
