Devices and methods for controlled release of substances

Abstract

A controlled release device and method of use, the device comprising a reservoir wherein the reservoir is divided into one or more chambers; a first active material placed in a first chamber of the one or more chambers and at least one second active material placed in at least one other of the one or more chambers wherein the first active material comprises an active ingredient (AI), wherein the AI is one of an insecticide, a spatial repellent, a herbicide or a larvicide; wherein the at least one second active material comprises one or both of a matrix and an altering material; a permeable membrane covering the first chamber; partitions positioned between adjacent chambers of the one or more chambers for dividing the reservoir into chambers such that full or partial removal of one or more of the partitions results in mixing of the first active material and the at least one second active material to form a mixed active material; a cap positioned over the membrane for sealing the reservoir such that removal of the cap results in controlled release of the AI from the mixed active material through the membrane.
