An insecticide organic fertilizer composition eradicates insects such as imported fire ants (IFA). The insecticide organic fertilizer composition comprises an aqueous homogenized manure extract having an active ingredient, a surfactant, a solvent, and a fatty acid. Active ingredients include botanical insecticides which are subject to degradation after a preselected period of time upon delivery to a soil area. The botanical insecticide is selected from the group consisting of rotenone, pyrethrum, sabadilla (varatrine), neem (azadirachtin), ryania (ryanodine), and mixtures thereof, with rotenone being the preferable botanical insecticide selected. Advantageously, the combination of these components and component amounts renders the botanical insecticide's active ingredients, including rotenone, stable in the aqueous organic manure extract for a predetermined period of time. During this predetermined period of time, the insecticide organic fertilizer composition biologically interferes with IFA's pheromone distress signals. Upon application of the insecticide organic fertilizer composition to an IFA mound, the IFAs began to exhibit a state of sluggishness and gradually begin to die over time rather than relocating, effectuating effective eradication after treatment. In addition, the biotanical insecticide functions to fertilize and nourish soil near the vicinity of the mound.
