Anti-Weevil spray

Anti-Weevil spray was developed by Torchwood Three to capture and subdue the Weevils living in the sewers of Cardiff. (TV: Everything Changes) Over time, the Weevils developed an immunity to the spray. (TV: Combat)

Jack Harkness once packed the spray on a trip to the Casa Celi for what the team thought was an "evening jolly". (PROSE: Another Life)
