Abstract: Disclosed are a pest control agent, a method for preparing a pest control agent, and a method for controlling a pest. Generally, the pest control agent is formed by providing a porous starch and an active control agent absorbed within the porous starch, and compressing the porous starch in the presence of heat to form discrete plural particles. Preferably, one or more binders are employed, as are one or more secondary absorbents/fillers. In highly preferred embodiments of the invention, the pest control agent is prepared via pelletizing in a commercial pellet mill. The particles so prepared should be sufficiently durable to withstand bulk transport, such as by rail car or bag shipment. The particles should, however, release the control agent quickly upon contact with water, such that, for instance, the control agent may be released when the pest control agent is introduced to standing water. It is contemplated that the control agent is preferably a mosquito control agent.

Abstract: Disclosed are a pest control composition, a method of pest control, and a method for preparing a pest control composition. The pest control composition includes diatomaceous earth, a porous granular starch, and a control agent, the control agent generally being an oleaginous material that is film-forming on a water surface. The pest control composition generally is in the form of discrete plural compacted particles. Upon release, for instance, onto a body of water, the control agent will be released from the pest control composition and will form a film over at least a portion of the body of water.
