The Instinct Factor boilie is one of the new breed of Performance Concept boilies developed to provide carp with all their nutritional needs. Only the highest grade natural ingredients have been used with no artificial colourings or flavours. Instinct Factor boilies are rich in organic extracts coupled with shellfish proteins and vitamins. The combination created by the organic blends of ingredients matched to the obvious palatability of this naturally coloured boillie creates a food item which the carp will find instinctively attractive. Instinct Factor – as its name suggests- has proved itself consistently as an instant fish catcher but has alsohad dramatic results with the field testers when introduced over a longer period.
