A method of manufacturing and the product formed thereby are set forth; the product relates to an encapsulated insecticidal bait which in the preferred and illustrated embodiment has a surrounding shell about a core. The core is formed of a volatile fumigant or ingested toxicant mixed with an insect species attractant food such as soybean oil. The core is enclosed in a shell formed by a two part polycondensate system forming the shell about the core. A first part and a liquid define an interfacial contact around a bead of the first part wherein beads of the core material form droplets in the water. The polycondensate system is defined by the two-part intermediates, where the second part is added to the liquid ratably to encapsulate the droplets.
