Abstract
Abstract Articles of manufacture are disclosed for the controlled delivery of pest controlling substances. Methods for producing such articles and utilizing them in pest control programs are also described. Laminated articles are provided which comprise one or more layers containing active pest control and pest attractant substances and which allow the controlled release of the pest controlling substance from within the laminate to the surface of the laminate so as to maximize efficiency against target species in the surrounding environment. The laminated structure also permits prolonged, controlled release of pest controlling substances and properly timed combinations of such substances that might otherwise be prematurely dissipated, decomposed or inefficiently applied. Various combinations of polymeric materials and active agents and a number of different laminated structures are utilized to optimize efficient use of the pest controlling substance against a variety of target species.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
261 words
A trap for insects comprising: a chamber formed at least in part from a laminated dispenser material, said chamber having at least one opening to allow outward passage of the vapors of a volatile insect attractant agent evaporating from the surface of said laminated dispenser material, and also to allow ingress of insects attracted by said volatile insect attractant agent, wherein said laminated dispenser material comprises: at least a first solid, non-porous, polymeric wall element having at least a first outer surface exposed to the environment of said dispenser, connector means on said trap for mounting said trap on another structure, at least one inner layer of said laminate between said first and second wall elements comprising a layer of a solid, polymeric composition, said inner layer comprising: at least one pest controlling agent and at least one volatile insect attractant agent, said agents being capable of migrating through said first wall element and being present in said inner layer in sufficient amount so that upon migration of at least a portion of each of said agents through said first wall element, effective levels of said pest controlling agent and said volatile insect attractant agent are present on said first outer surface of said wall element, and said pest controlling agent and said volatile insect attractant agent having rates of migration through said wall element so that said agents become available upon said first outer surface of said first wall element and in the surrounding environment in accordance with a desired dosage regimen for effective control of a target insect species.
Claim 2
Dependent Claim
261 words
A trap for insects comprising: a chamber formed at least in part from a laminated dispenser material, said chamber having at least one opening to allow outward passage of the vapors of a volatile insect attractant agent evaporating from the surface of said laminated dispenser material, and also to allow ingress of insects attracted by said volatile insect attractant agent, wherein said laminated dispenser material comprises: at least a first solid, non-porous, polymeric wall element having at least a first outer surface exposed to the environment of said dispenser, connector means on said trap for mounting said trap on another structure, at least one inner layer of said laminate between said first and second wall elements comprising a layer of a solid, polymeric composition, said inner layer comprising: at least one pest controlling agent and at least one volatile insect attractant agent, said agents being capable of migrating through said first wall element and being present in said inner layer in sufficient amount so that upon migration of at least a portion of each of said agents through said first wall element, effective levels of said pest controlling agent and said volatile insect attractant agent are present on said first outer surface of said wall element, and said pest controlling agent and said volatile insect attractant agent having rates of migration through said wall element so that said agents become available upon said first outer surface of said first wall element and in the surrounding environment in accordance with a desired dosage regimen for effective control of a target insect species.
Claim 3
Dependent Claim
25 words
The trap of claim 1, further comprising a second aperture in the lower region of said chamber to facilitate collection and removal of dead insects.
Claim 4
Dependent Claim
