Devices that provide timed-release of target compounds absorbed by, or otherwise integrated into, an external housing. The external housing absorbs and facilitates volatilization of the released compound. A permeable cover can be employed as a regulating mechanism to control the rate volatilization from the external housing. One or more reservoirs containing target compound can be contained within one or more internal chambers of the external housing. The one or more reservoirs can release the target compound for absorption by the external housing and/or to make contact with one or more other reservoirs so as to compromise the other reservoirs and release target compound within. A wick can be employed in certain embodiments to transfer target compound from the internal chamber to the external housing to be volatilized. Continued or sequential release of target compound to recharged the external housing achieves a zero order release rate from the external housing.

1. A release device comprising: an external housing formed from a material that absorbs and volatilizes one or more target compounds;at least one internal chamber located within the external housing, where the internal chamber has a mouth and is impermeable to the target compound;at least one reservoir disposed within the internal chamber, wherein the reservoir comprises a material that can be compromised to release into the internal chamber a liquid target compound stored within the reservoir; anda wick having a receiving end and a delivering end, where the receiving end is disposed within the internal chamber to absorb the target compound released from the reservoir and the delivering end passes through the mouth so as to be outside the internal chamber, where the internal chamber and wick are contained inside the external housing with the delivering end of the wick in contact with the external housing;such that the liquid target compound released when the reservoir is compromised is absorbed by the receiving end of the wick and transferred to the delivering end outside of the internal chamber where it is absorbed by all or most of the external housing and volatilized. 2. A release device, according to claim 1, further comprising a permeable cover at least partially surrounding the external housing, where the permeable cover controls the rate at which volatilized target compound is released from the external housing. 3. A release device according to claim 1, wherein the target compound released from the at least one reservoir compromises at least one other reservoir, so that target compound within that other reservoir is subsequently released. 4. A release device according to claim 2, wherein the external housing is pre-charged with target compound. 5. A release device according to claim 2, wherein the permeable cover comprises a material that allows volatilization therethrough. 6. A release device according to claim 2, wherein the permeable cover comprises a material with multiple perforations that allow volatilization therethrough. 7. A release device according to claim 1, wherein the at least one reservoir is mechanically compromised. 8. A release device according to claim 7, wherein the at least one other reservoir is chemically compromised. 9. A release device according to claim 1, wherein the external housing comprises one internal chamber with multiple reservoirs therein. 10. A release device according to claim 1, wherein the external housing comprises more than one internal chamber, each containing one or more reservoirs. 11. A release device according to claim 9, wherein the target compound, in at least one reservoir, is a triggering compound. 12. A release device according to claim 7, further comprising a container into which the external housing is disposed. 13. A release device according to claim 12, wherein the container mechanically compromises the at least one reservoir. 14. A release device, according to claim 1, wherein the external housing exhibits at or near a zero order volatilization. 15. A release device according to claim 1, wherein the external housing and the wick comprise substantially the same material. 16. A release device according to claim 1, wherein the external housing and the wick comprise different materials. 17. A method for controlling insects in a spatial area utilizing a release device comprising: an external housing formed from a material that absorbs and volatilizes one or more target compounds;at least one internal chamber located within the external housing where the internal chamber has a mouth and is impermeable to the target compound;at least one reservoir disposed within the internal chamber, wherein the reservoir comprises a material that can be compromised to release into the internal chamber a liquid target compound stored within the reservoir;a wick having a receiving end and a delivering end, where the receiving end is disposed within the internal chamber to absorb the target compound released from the at least one reservoir and the delivering end passes through the mouth so as to be outside the internal chamber, where the internal chamber and wick are contained inside the external housing with the delivering end of the wick in contact with the external housing;such that liquid target compound released when the reservoir is comprised is contained within the internal chamber, absorbed by the receiving end of the wick, and transferred to the delivering end outside of the internal chamber where it is absorbed by all or most of the external housing for volatilization;wherein the method comprises,compromising at least one of the at least one reservoir; andplacing the release device in a spatial area in which an insect is to be controlled. 18. A method according to claim 17, further comprising a container into which the release device is disposed. 19. A method according to claim 18, wherein the method further comprises utilizing the container to mechanically compromise the at least one reservoir.
