Inventor(s)
- "A potion of prodigious power, to repulse the vile Doxy. Students of my work may wonder why I chose to devote my genius to deterring these fairy-like nuisances. Suffice it to say that even hermits suffer from household pests. Hence I created this, a full-bodiedvenomous mixture, yet well-rounded."
- —Zygmunt Budge,Book of Potions[src]

History[]
Zygmunt Budge developed a recipe for Doxycide to deal with the swarms of Doxys that inhabitedHermetray during autumn. His first attempt, rather than repelling the Doxys, made them red-hot and fiery, thus settingfire to bothBudge'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.[3]

A bottle of Doxycide
Some Doxycide wasordered byPhineas Nigellus Black during the1890–1891 school year.[4] During the1986–1987 school year atHogwarts School of Witchcraft and Wizardry,ProfessorSeverus Snape taught histhird-years how to concoct this particular brew inPotions class.[2]
Due to an infestation ofDoxies in theSlytherin common room during the1987–1988 school year, Professor Snape tasked hisfourth-years with brewing this concoctionwithout consulting their notes to help them do so and instead rely upon theirmemory, with thePotions 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.[5] After dismissing the class, Snape came to regret his actions and later called Jacob's sibling to thePotions 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.[6]

The Doxy Queen drowning in Doxycide
During the1990–1991 school year,Jacob's sibling and their friends used Doxycide again to eradicate an infestation of doxies inHogwarts Castle. They killed theDoxy Queen responsible for the infestation in thePrefects' Bathroom, byknocking her into bathwater mixed with Doxycide, drowning her.[7]
In the summer of1995,Molly Weasley and the adolescents at12Grimmauld Place used it to remove Doxies from the draperies at the headquarters of theOrder of the Phoenix.[1]Fred andGeorge Weasley used Doxycide to paralyse Doxies before pocketing them, intending to use theirvenom in the development of theirSkiving Snackboxes.[1]
During theCalamity in the late2010s or early2020s, awizarding greenhouse on theIsle of Skye suffered from an infestation of Doxies, although they lacked the Doxycide to effectively remove them. ACalamity Investigator working for theStatute of Secrecy Task Force travelled to the island to help out the greenhouse owners, suffering numerous bites and scratches during the tedious work but eventually managing to remove the infestation.[8]
Behind the scenes[]
- Doxycide has a very similar name to the real-world medicationdoxycycline, an antibiotic used to treat certain bacterial infections and parasites.
- In chapter 18 of year 7 ofHarry Potter: Hogwarts Mystery, Jacob's sibling decides it is best to douse the Doxy Queen in this potion by pouring it directly from a bottle over her.[7] However, as the game itself shows, this is highly impractical, since the potion is administered as a spray, so it seems odd that the game would choose to depict Doxycide being used in this manner.
