Abstract: A crawling insect abatement matrix, system and method includes a cellular, nonwoven, wet laid or fibrous substrate with a shaped surface to which diatomaceous earth (diatomite, kieselgur, amorphous silica) particles are bound, either in situ or with a binder/coating applied to the substrate. A representative cellular substrate is polyurethane foam with a convoluted or otherwise shaped surface to which a coating that includes diatomaceous earth particles has been applied. The substrate is formed as a sheet, mat or pad that may be installed between a mattress and bedding structure or bedding textiles or below furniture articles, or in clothing compartments, or formed as a tape that may be applied to a surface of a mattress, a bedding structure, a headboard, bedding textiles, or to a clothing compartment.

Abstract: A gutter protector formed of a flexible open cell porous foam has at least one undulated bottom surface. The undulations of the bottom surface may be ridges defining generally parallel channels to direct water through the gutter passageway. Optionally, undulations may be provided on one side surface. Such undulations on the side surface may be ridges or other convolute cut projections that are compressible and help to secure the gutter protector under compression within the gutter passageway.
