Researchers Submit Patent Application, "Apparatus to Block Pest Mobility and Locomotion", for Approval

August 28, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventor McAllister, Kevin (New York, NY), filed on February 1, 2013, was made available online on August 14, 2014.

No assignee for this patent application has been made.

News editors obtained the following quote from the background information supplied by the inventors: "Many pests are particularly troubling to man. These include but are not limited to the bed bug, termite, cockroach, flea, tick, mosquito, etc. The bed bug, for example, has seen a resurgence in the last 10 years and is of particular trouble due to its tremendous resilience and increasing resistance to pesticides. Bed bugs feed on blood, cause itchy bites, and generally irritate human hosts. Although they are not known to transmit or spread disease, they can cause other public health problems. Consequently, preventing and/or controlling bed bugs is a real public health concern. Recently publicized incidents of bed bug infestations in the United States indicate that public pest control practices may be ineffective. Chemical methods to prevent and/or control bed bug infestations can be costly, complex, and limited in usefulness as bed bugs' resistance to pesticides increase over time. There are few widely-used non-chemical methods that attempt to reduce bedbug infestations (for example, encasement of bedding). However, none actually prevent infestation or prevent feeding but simply force bed bugs to live and breed farther from the food source. In the case of mattress covers, bed bugs simply nest in the bed frame or behind wall hangings or other furniture close to the bed, emerge at night, crawl to the sleeping host, feed and return to their hiding place once engorged.

"Bed bugs are approximately 4-5 millimeters long. They are broad and flat in shape, brown in color, and glisten from a distinctive, smelly oil secreted from scent glands. The wings are scale-like and vestigial. Females lay about 200 or more eggs during reproductive periods, and can lay around a thousand eggs during several such periods within a year. Bed bugs do not mature and procreate without feeding. Bed bugs feed chiefly at night in the wild. They feed on the blood of birds and small mammals, and within human-inhabited areas they feed upon domesticated animals as well as man. They retreat to their hiding places during the daytime, using up to several days in which to digest their food. Most bed bugs live full time within eight feet of where humans sleep. When hiding they are generally found in bedding and mattresses (hence the name), nearby furniture, carpeting, within dressers and clothes, curtains, and cushions.

"It would be advantageous to have a low cost, passive, and chemical-free method to prevent and/or control insect pests, such as bed bugs from feeding on humans or other mammals such as household pets. It would be advantageous to have a method to prevent and/or control insect pests that exploit weaknesses in how insects live and grow."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "An embodiment of the invention obviates the above problems by providing an apparatus that controls the mobility of insects, comprising a substrate having a top surface, a bottom surface, and a side surface that connects the top and bottom surfaces and a plurality of entangling fibers situated on one of the respective surfaces, said plurality of entangling fibers forming at least one opening therein sized and shaped to allow for easy entrance of the initial bulk of an insect appendage and for loose fitting around the remainder of the insect appendage. The plurality of entangling fibers may be configured as interlaced fibers. In such case, the interlaced fibers may be configured as intersecting fiber filaments or as interconnected loops. The interlaced fibers may be formed to be fixedly interconnected. The plurality of entangling fibers may be configured as a series of adjacent, parallel fibers. The series of adjacent, parallel fibers may be formed to spread upon contact pressure with an insect and an opening between two respective adjacent, parallel fibers is formed upon a spreading of the two respective adjacent, parallel fibers.

"The apparatus may further comprise a nanoparticle situated on a respective fiber that is adapted, upon contact with a respective insect, to pass from the respective fiber and through the exoskeleton of the respective insect. The nanoparticle may comprise a toxin, a coagulant, or a combination of a toxin and a coagulant.

"The plurality of entangling fibers may be configured to project from the top surface so as to permit a respective insect appendage to easily engage and enter the at least one opening. Also, the respective surface having the plurality of entangling fibers situated thereon may be formed to have an irregular surface so as to create a space or spaces underneath the entangling fibers. The space or spaces underneath the entangling fibers may be sized and shaped so as to permit a respective insect appendage to pass through the at least one opening that overlies the space or spaces.

"Another embodiment of the invention provides an apparatus to impede the locomotion of insects, comprising a substrate and an entangling pad of fibers located on a respective surface of the substrate, said entangling pad being configured with a plurality of pad openings therethrough which are dimensioned to capture an insect appendage during the movement of a respective insect on the substrate. The entangling pad of fibers may be configured as an interwoven pad of fibers. In such case, the interwoven pad of fibers may be configured as a plurality of intersecting fiber filaments or as a plurality of interconnected loops. The entangling pad of fibers may be configured as a series of adjacent, parallel fibers. The series of adjacent, parallel fibers may be formed to spread upon contact pressure with a respective insect and a pad opening between two respective adjacent, parallel fibers is formed upon a spreading of the two respective adjacent, parallel fibers.

"The apparatus may further comprise a plurality of nanoparticles situated within the entangling pad of fibers that are each adapted, upon contact with a respective insect, to pass from the entangling pad of fibers and through the exoskeleton of the respective insect. The nanoparticles may comprise a toxin, a coagulant, or a combination of a toxin and a coagulant.

"The entangling pad of fibers may be configured to project from the respective surface of the substrate to permit an insect appendage to pass through a respective pad opening. Also, the respective surface having the entangling pad of fibers located thereon may be formed to have an irregular surface so as to create a space or spaces underneath the entangling pad of fibers. The space or spaces underneath the entangling pad of fibers may be dimensioned to permit a respective insect appendage to pass through a respective pad opening.

"Another embodiment of the invention provides a method of impeding the movement of insects, comprising the steps of forming an entangling fiber structure on a surface of a substrate; configuring the entangling fiber structure with a plurality of openings therethrough which are dimensioned to capture an insect appendage during movement of a respective insect on the substrate; and creating a spacing between the entangling fiber structure and at least one portion of the respective surface having the entangling fiber structure formed thereon so as to permit a respective insect appendage to pass through a respective opening that overlies the spacing. The method may further comprise the step of situating a plurality of nanoparticles on the entangling fiber structure that are adapted, upon contact with a respective insect, to pass from the structure and through the exoskeleton of the respective insect, said nanoparticles comprising a toxin, a coagulant, or a combination of a toxin and a coagulant.

"Another embodiment of the invention provides a method of constructing a structure that impedes the movement of insects, comprising the steps of providing a substrate; forming a plurality of entangling fibers on a respective surface of the substrate; and configuring the plurality of entangling fibers with a plurality of openings therethrough which are dimensioned to capture an insect appendage during the movement of a respective insect on the substrate. The forming step may comprise forming a plurality of entangling fibers that project from the respective surface of the substrate to permit the insect appendage to pass through a respective opening. The providing step may comprise providing a substrate having an irregular surface and the forming step may comprise forming the plurality of entangling fibers on the irregular surface so as to create space or spaces underneath the plurality of entangling fibers that are dimensioned to permit the insect appendage to pass through a respective opening. The forming step may comprise spinning polymer as a raw material for the fibers and depositing resulting fiber filaments onto the respective surface of the substrate. The forming step may comprise utilizing a melt-blowing process to deposit resulting fiber filaments onto the respective surface of the substrate.
