Abstract: A method of forming an active control ingredient that controls target living species over an extended period of time commences by providing a clay material that has a structure substantially depleted of platelets (“aplatelet”). The aplatelet clay material is heated with a solid active control agent to a temperature of at least about 10° C. above the melting point of the solid active control agent. The aplatelet clay material then is loaded with the heated solid active control agent.

Abstract: A method for attracting cockroaches to an object or area, involving treating said object or area with a cockroach attracting composition containing a cockroach attractant effective amount of at least one compound selected from the group consisting of methyl, ethyl, propyl, or butyl esters of C3-7 saturated or unsaturated carboxylic acids and mixtures thereof, and optionally a carrier material or carrier. A method for repelling cockroaches from ah object or area, involving treating said object or area with a cockroach repelling composition containing a cockroach repelling effective amount of at least one compound selected from methyl, ethyl, propyl, or butyl esters of C3-7 saturated or unsaturated carboxylic acids or mixtures thereof, and optionally a carrier material or carrier.

Abstract: One aspect of the invention is a method of controlling target living species with an active ingredient over an extended period of time. This method sorbs an active ingredient into colloidal clay. Next, a polymer pellet recalcitrant to release of the active ingredient is loaded with the sorbed colloidal clay. Finally, the loaded polymer pellet is formed into a barrier, which is adapted to be placed at a location for controlling a target living species. Another aspect is a barrier for controlling a target living species. The formed barrier contains polymer pellets loaded with colloidal clay sorbed with an active ingredient that controls the target living species. The sorbed clay loaded polymer pellets are recalcitrant to release of the active ingredient.
