|Gilderoy Lockhart's Guide to Household Pests|
Gilderoy Lockhart's Guide to Household Pests is one of the many books written by Gilderoy Lockhart. It includes advice on how to get rid of household pests. It can be assumed that Gilderoy Lockhart is not the real author, due to his fraudulence, although the real author is never identified. Similarly, the methods inscribed within may not have been devised by Lockhart, but instead by someone else. Interestingly enough, although the subject of this book is on house care, the front cover features Gilderoy Lockhart, a sign of his vanity.
Molly Weasley used it to find instructions on how to get rid of the Doxies that were in the curtains at 12 Grimmauld Place, and at The Burrow, to help Harry, Ron, and Fred and George get rid of the gnomes in the Burrow's garden, but the twins said that they already knew how without the help of the book.
