A landscaping fabric that includes a pesticide is made by extruding molten polypropylene from a plurality of holes to generate filaments. The filaments are cooled and drawn to cause the filaments to become reduced in diameter. The filaments are distributed onto a belt to form a mat and the mat is compressed to bond the filaments into a nonwoven fabric. An insecticide is applied to the nonwoven fabric and the nonwoven fabric and insecticide combination is dried.
