Abstract
In one aspect, the present invention is directed to an ampoule for the storage and dispersion of a volatile liquid comprised of (a) an outer shell composed of an impermeable material and defining at least one opening; (b) a porous diffusion member defining an internal reservoir positioned inside said outer shell; (c) a volatile liquid contained within such internal reservoir; and (d) a film member adhered to the outer shell and covering the at least one opening; wherein the film member is disposed such that an air space is present between the porous diffusion member and the film member; and wherein the porous diffusion member is configured such that molecules of the volatile liquid can only enter into the air space via diffusion through the porous diffusion member. Such ampoules are particularly suited for the storage and dispersion of organic chemicals useful as bed bug attractants, such as a C8-C12 alkane. In another aspect, this invention is directed to a device adapted to receive one or more of such ampoules. In one preferred embodiment, such device is a bed bug capturing device.
