The invention is a polymeric composition and a method of forming a composition in which a pesticidal desiccant is homogeneously dispersed throughout the polymer. The desiccant is of appropriate size to be incorporated into a polymer melt for eventually forming articles, such as melt spun fibers, from the polymer-desiccant mix. The desiccant may be embedded throughout the body of an article, particularly fibers, produced pursuant to this invention. Silicon dioxide based desiccants that are present within the polymer matrix in an amount between about 0.1 and 2.5 weight percent are useful to provide absorptive properties pursuant to this invention. The desiccant dehydrates the microscopic reservoirs of moisture on which pests, such as a dust mite, survive. In this regard, the invention prevents pests from infesting and thriving on articles formed of the desiccant enhanced polymeric composition.
