Organised pest control will keep the numbers of foxes down. There are many exemptions to the ban on fox hunting, primarily to protect damage to livestock, game and wild birds, growing timber, fisheries and other property. These exemptions allow the shooting of wild mammals (not just foxes) if certain conditions defined in the Hunting Act 2004 have been met.
Please see the links in Related Information for further information. There is also a link to the RSPCA website as they provide guidance on how to deal with any foxes in your area and how to deter their presence.
