A method and packages for releasing volatiles of a semiochemical at a controlled or pre-selected rate are disclosed. The package containing the semiochemical includes at least one portion that is permeable to the volatiles. In some embodiments, the package is formed as a stick pack, and includes a plurality of micro-perforations having characteristics, such as size, density, and shape, that are selected to achieve a desired release rate. In an embodiment, the package is formed from a plurality of laminae, and at least one of the laminae is formed from a material that is selected for its permeability to the semiochemical volatiles. In an embodiment, the package includes a portion that is peeled away to expose a layer that is permeable to the semiochemical volatiles. |
