The Vermin Repelling Charm (incantation: repello vermis) is a spell used to protect an area against insects.
Julia King used the spell to shield Alexandra Quick's bedroom when Quick visited the King family ranch on Croatoa.
Maximilian King later used the spell disperse "clouds of black flies" that he and Quick encountered on their journey through the Lands Below.
