Doxycide is a black-coloured foul smelling solution used to spray Doxies. It paralyses them for a period of time, allowing the user to safely remove the Doxies without fear of being bitten. The recipe can be found in Book of Potions.^[1]

History

Zygmunt Budge developed a recipe for Doxycide to deal with the swarms of Doxys that inhabited Hermetray during autumn. His first attempt, rather than repelling the Doxys, made them red-hot and fiery, thus setting fire to both Budge's house and the island itself. Budge was forced to spend that night in the sea, breathing through a hollow stick. Budge perfected his Doxycide the following autumn, killing the entire swarm and allowing him to sweep their corpses into the sea.^[1]

During the 1986–1987 school year at Hogwarts School of Witchcraft and Wizardry, Professor Severus Snape taught his third-years how to concoct this particular brew in Potions class.^[2]

Due to an infestation of Doxies in the Slytherin Common Room during the 1987–1988 school year, Professor Snape tasked his fourth-years with brewing this concoction without consulting their notes to help them do so and instead rely upon their memory, with the Potions Master also issuing a stern warning for his class to not disappoint him, as dealing with Doxies had put him in a rather sour mood. Having finished brewing their own concoction, Jacob's sibling proceeded to write a note asking their secret crush if they returned their feelings. Having noticed this and misconstruing it as them consulting their notes despite his explicit instructions forbidding them to do so, a livid Snape confronted Jacob's sibling and swiftly snatched up their note, believing that the class should have the same advantage as they supposedly did. Despite the student's earnest protests, Snape, unaware what their message really contained, proceeded to read aloud their note to the entire class, much to Jacob's sibling's humiliation.^[3] After dismissing the class, Snape came to regret his actions and later called Jacob's sibling to the Potions classroom under the pretext of enlisting their help to brew more Doxycide Potion. After brewing with them, Snape acknowledged that his reading aloud their note in class had prompted "idle chatter" among the student body, which he disclosed that he detested, as it could be especially cruel when it came to matters of the heart, thus indirectly apologising to Jacob's sibling for his earlier actions.^[4]

Molly Weasley and the adolescents at 12 Grimmauld Place used it to remove Doxies from the draperies at the headquarters of the Order of the Phoenix.^[5]

Fred and George Weasley used Doxycide to paralyse Doxies before pocketing them, intending to use their venom in the development of the Skiving Snackboxes.^[5]
