Abstract:
Disclosed are substrates suited for dispensing air treatment chemicals upon being heated. Granular particles, preferably sand with a phenolic binder, are adhered together to form a substrate body having a network of pores. A volatile air treatment chemical is disposed in the pores. The particle size and pores are such that the smaller particles of the substrate are grouped at one end, preferably an end adjacent to a projecting nose. This structure tends to wick the volatile air treatment chemical towards the nose, and heating that area can lead to efficient, and rechargeable, dispensing. Methods for using such substrates, and methods for forming such substrates, are disclosed.
Abstract:
A membrane enclosed fluid diffusion system for insect attractants and repellents, auto thermostatic heaters, and chemical delivery using an additive and/or selectively permeable membrane that interacts with the enclosed fluid to maintain steady delivery rates over a range of temperature and humidity. Systems can be formed with permeable membranes, impermeable membranes, chemical hydrates, wicks, scent fluids, fuel fluids, catalytic heaters, energy conversion devices, visible images, infrared images, trapping systems, sound systems, electronics, and apparel. The device results in efficient and effective devices for mosquito control drug delivery, and portable heaters.
Abstract:
A pest-combating composition including sodium lauryl sulfate and one or more of C6-12 fatty acids, preferably lauric and/or capric and/or caprylic acid, soy methyl ester, and 2-undecanone, and methods of combating pests utilizing same, are disclosed. The compositions can include a carrier oil such as silicon oil, soy methyl ester, or a vegetable oil, and can be in the form of an emulsion. The composition may be constituted as a spray composition, an aerosol, a lotion, a paste, or another compositional form. Pests that may be usefully combated with such composition include flying insects, including flies, mosquitoes, and wasps, ants, including arthropods such as fire ants, ticks, fleas, cockroaches, silver fish, thrips, gnats, aphids, Japanese beetles, and agricultural and horticultural arthropods and insects including beetles (potato and bean), flea beetles, fleahoppers, squash bugs, slugs, leaf hoppers, harlequin bugs, milk weed bugs, spiders, mites, lice, rodents, and deer.
Abstract:
Disclosed herein is a pharmacophore model for arthropod repellent activity and methods of making and using thereof. The pharmacophore comprises two hydrophobic aliphatic functions, one aromatic function and one hydrogen bond acceptor function. The pharmacophore model was made using a test set of arthropod repellent compounds. Also disclosed are arthropod repellent compounds identified by screening databases with the pharmacophore model. Also disclosed are methods of repelling arthropods from a surface or area. Compositions and formulations comprising the compounds of the present invention as well as objects having the compounds of the present invention are disclosed.
Abstract:
An insect repellent composition that includes a blend of either all natural oils or synthetic ingredients, a sunscreen vitamin F, volatile silicones to extend the effective repellent life of the spray and a film forming polymer to resist water wash off. The natural oils and extracts can include citronella and orange and the synthetics can include D-limonene and phtalic acid.
Abstract:
The present invention provides an insect repellent fragrance comprising; (a) at least 10% by weight of the insect repellent fragrance of geraniol; (b) at least 10% by weight of the insect repellent fragrance of diethyl phthalate; and (c) at least one or more of linalol, limonene, citronellal, terpinolene and p-tertiary butyl cyclohexyl acetate; wherein the insect repellent fragrance comprises at least 60% by total weight of the insect repellent fragrance of (a), (b) and (c). The insect repellent fragrance surprisingly demonstrates effective repellency, particularly against cockroaches, and more particularly against both German and American cockroaches.

Abstract:
Disclosed are a pest control agent, a method for preparing a pest control agent, and a method for controlling a pest. Generally, the pest control agent is formed by providing a porous starch and an active control agent absorbed within the porous starch, and compressing the porous starch in the presence of heat to form discrete plural particles. Preferably, one or more binders are employed, as are one or more secondary absorbents/fillers. In highly preferred embodiments of the invention, the pest control agent is prepared via pelletizing in a commercial pellet mill. The particles so prepared should be sufficiently durable to withstand bulk transport, such as by rail car or bag shipment. The particles should, however, release the control agent quickly upon contact with water, such that, for instance, the control agent may be released when the pest control agent is introduced to standing water. It is contemplated that the control agent is preferably a mosquito control agent.
Abstract:
The short term effectiveness of pesticidal articles, for example pesticide impregnated textile covers for use in combating dust mite infestation, is improved by the additional presence of a quick release pesticide thereon, e.g. a wettable powder formulation of the same pesticide as used for impregnation. The invention is of particular value in the area of pyrethroid containing textile covers, e.g. as disclosed in U.S. Pat. No. 5,916,580.
