Abstract: The invention provides an improved insect bait composition comprising a boric compound, a non-sugar low molecular weight compound having a plurality of hydroxyl groups, and a foodstuff comprising a substantial amount of a soluble or semi-soluble high molecular weight polysaccharide, wherein the high molecular weight polysaccharide is in a gelled form, the composition is a sustainably soft dough, and the foodstuff contains no more than 20 weight percent of a fat or oil. The composition is suitable for extrusion, is attractive and highly toxic to insects, and has excellent resistance to hardening and spoilage during its shelf life and after pesticidal application.
