1. A method of manufacturing at least two nested insect coils, comprising the steps of:
providing a sheet of dough material comprising an insect coil composition, said dough material having an outer substantially planar upper surface;
cutting said sheet of dough material with a die to form two nested insect coils, both of said insect coils having their own tip end;
ejecting the nested insect coils from the die by moving an ejector between a non-ejecting position and an ejecting position; and
applying a fluid mixture containing an active insect control ingredient to the respective tip ends of the insect coils while said coils are being ejected from said die, wherein the step of applying said fluid mixture comprises dispensing, as said ejector initially begins to eject said nested coils, a discreet amount of said fluid mixture to dosing ports disposed closely spaced above the outer upper surface so that said discreet amount of said fluid mixture touches said outer substantially planar upper surface and as the ejector then continues to eject the nested coils from the die in a direction away from said dosing ports capillary forces between said outer substantially planar upper surface and said fluid mixture at said dosing ports draw the discreet amount of said fluid mixture from said dosing ports onto the outer substantially planar upper surface to form a droplet on both of the respective tip ends of both of the coils, while not applying said fluid mixture on top of at least some other portions of said outer upper surface of the coils.
