Deep Insect Boilies are mainly made from insects and naturally occurring microorganisms from lakes and rivers.
Insects and microorganisms are part of the carp’s natural source of nutrition.
Organic "fast food", rich in protein and high in fat!
Koi carp, in particular, cannot let go of their fins, as they are preferably fed with insects in breeding farms.
An interesting boilie that can bring many a surprise catch with it.
