Abstract:
A pest control material (11), such as mosquito netting, has a surface (12) with abrasive/absorptive microprojections (13). Insect pests such as mosquitoes suffer damage to their cuticle, resulting in dehydration and/or invasion by microbial pathogens. The material is made by coating a fabric with abrasive and/or absorptive materials.
Abstract:
A tree band trap includes a formfitting substance engaging and extending around the trunk's outer circumference, a stretchable strip mounted to the trunk and having a length extending in a longitudinal direction and around the formfitting substance's outer circumference, and a deterring agent extending around the stretchable strip's outer circumference for deterring insects from traversing the stretchable strip. The stretchable strip is operative so that, after the stretchable strip is mounted to the trunk, the stretchable strip is under tension in the longitudinal direction as a result of the stretchable strip having been stretched, and the tension of the stretchable strip forces the formfitting substance against the trunk's outer circumference. A marginal portion of the stretchable strip extends around the trunk's outer circumference at a position that is above and/or below the formfitting substance. A deflector is provided for deflecting falling leaves away from the deterring agent.
Abstract:
The system and method for preventing the passage of crawling insects upon the exterior surface of an object includes a member having an inner surface, adapted to be disposed adjacent to the exterior surface of the object, an opposed outer surface that has a low coefficient of friction for preventing the insects from traversing the outer surface since the crawling insects are unable to obtain sufficient traction with the outer surface of the member, a means for affixing the member to the exterior surface of the object so that the insects are forced to attempt to traverse the outer surface of the member in order to reach the exterior surface of the object above the member.
Abstract:
A device for exterminating pests includes a belt consisted of the first side plate and the second side plate which is connected to the first side plate on the two respective first sides thereof so that an opening is defined between the two respective second sides of the two side plates. Each of the first side plate and the second side plate has an engaging device attached to the inside thereof so as to be engaged with each other. Insecticide is received between the first side plate and the second side plate, and the belt is wrapped around the trunk of trees.
Abstract:
A crawling pest barrier for placement on a conduit to prevent crawling insects or pests from reaching the outlet of the conduit. A combination of -tactic, ultraviolet light and other barriers are positioned along the conduit with respect to the path of travel of the crawling pest to the outlet of the conduit.
Abstract:
A coating (17) and a method for its preparation are disclosed which will restrict the movement of insects over a skewed surface (15) to which the coating is applied. The coating (17) is an adherent thin film comprised of particles of less than 5 microns. The dispersions are prepared using a surfactant. The surfactant may be removed, at least in part, from the film by leaching or evaporation. The dispersion may also include a dispersing agent which need not be removed from the film. Stabilizing agents may be added to protect the dispersions from freeze/thaw cycles. The coatings (17) are preferably applied by spraying or roller coating the dispersion over the surface (15).
Abstract:
A dispersion of a polytetrafluoroethylene resin having a particle size between about 0.05 and 0.5 microns, a suspending agent and a viscosity less than 15 centipoise. The dispersion has long shelf life, a reduced tendency to fibrillate and is comparatively stable when acted upon by shear forces and elevated temperatures. The dispersion is well adapted to be sprayed onto surfaces to form a dried film upon which insects can not climb, alight or affix nests or webs. The dispersion can be sprayed without fibrillation dispersion and the dried coatings are adherent, may be washed and remain effective over long periods of time.
Abstract:
A novel composition is described which comprises a mixture of at least one aliphatic aldehyde in the range of two to seven carbon atoms (C.sub.2 -C.sub.7), at least one sulfide, disulfide or mercaptan, ranging from one to fourteen carbon atoms (C.sub.1 -C.sub.14), at least one diketofuran in the range from five to seven carbon atoms (C.sub.5 -C.sub.7), at least one carboxylic acid, ranging from one to fourteen carbon atoms (C.sub.1 -C.sub.14) in an appropriate carrier, which when applied to a tree in a form of a closed band, prevents Gypsy Moth larvae and other hardwood defoliators to ascend the tree and thus interrupts the feeding cycle of these defoliators. The method of the composition and a preferred device for the application to trees are described.
Abstract:
A trap of conic section attached along an upper edge by a spring around the tree trunk can be closed around the tree trunk by a zipper attached along a vertical side of the trap to the trap, the trap forms a trough along an inner edge of the bottom of the trap into which an insecticide may be dripped by a tube passing through the side of the trap and connected to a canister which is also attached to the trap in which the insecticide may be stored and from which the insecticide may drip into the trough.
