Pest-control compositions are variously described, including soaps as well as free fatty acids as active ingredients. The disclosed compositions may be constituted in a concentrated form, or the composition may be further diluted for application. Pesticidal compositions of the disclosure may be employed to selectively target pests without a systemic mode of action, and may be used to control a wide variety of insects, arthropods, and other pests, at and/or in a locus that contains or is susceptible to emergence thereof.
