Westminster packs more restaurant kitchens per square mile than anywhere else in the country, and that concentration of food waste sets the agenda for pest control here. Soho's cellars, Mayfair's Georgian townhouses and Pimlico's Regency terraces each bring their own problems, but the constant is volume — bin stores that fill faster than they are emptied, and service yards shared between a dozen premises.
