DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to the control of pests such as insects and, more particularly, to a non-hazardous pest control agent that eliminates pests through mechanical puncture of the exoskeleton and neural effects of a component entering the puncture.
BACKGROUND OF THE INVENTION
Insects and other pests have long plagued humankind. Over the years, various approaches have been taken to control pests and especially insects, and none have been completely satisfactory.
For example, the use of complex, organic insecticides, such as disclosed in U.S. Pat. Nos. 4,376,784 and 4,308,279, are expensive to produce, can be hazardous to man, domestic animals, and the environment, and frequently are effective only on certain groups of insects. Moreover, the target insects often build an immunity to the insecticide.
Another approach employs absorbent organic polymers for widespread dehydration of the insects. See, U.S. Pat. Nos. 4,985,251; 4,983,390; 4,818,534; and 4,983,389. However, this approach is limited predominantly to aquatic environments, and it likewise relies on hazardous chemical insecticidal agents. Further, the addition of essential oils is primarily as an insect attractant.
In addition, this approach is based on the selective absorption of a thin layer of insect wax from the exoskeleton and not to a puncture of the
The use of inorganic salts as components of pesticides is reported by U.S. Pat. Nos. 2,423,284 and 4,948,013, European Patent Application No. 462 347, Chemical Abstracts 119(5):43357q (1993) and Farm Chemicals Handbook, page c102 (1987). These references disclose the inclusion of these components but not the puncturing of the exoskeleton of the insect by the salts.
The marketplace is replete with toxic chemical insecticidal agents that are offensive to apply and, more importantly, pose a danger to humans and the environment.
It would be greatly advantageous to solve these problems with an insecticidal agent that works mechanically and with a penetrating fragrance to kill pests, thereby eliminating the need for any toxic chemicals.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the invention to provide a method for non-hazardous pest control and a composition for the same which kills pests mechanically and neurally.
It is another object to provide a safe, non-toxic pest control agent that will not harm the environment.
It is another object to provide a pest control agent that is highly effective in combating a wide variety of pests, including all insects having an exoskeleton.
It is another object to provide a pest control agent which has a pleasant scent, and which can be applied without burdensome safety precautions.
It is still another object to provide a pest control agent as described above which can be inexpensively produced.
It is yet another object of the invention to provide a pest control agent to which pests cannot build an immunity.
In accordance with the above-described and other objects, the present invention provides a method for delivering a pest control agent directly through the exoskeleton of an insect by applying a composition comprised of powdered crystals and a fragrance. The powdered crystals puncture the exoskeleton of the insect and penetrate therein. The puncture in the exoskeleton of the insect permits the entry into the insect's body of a fragrance which interferes with the body function of the insect. The method of the invention also encompasses killing the insect by dehydration using powdered crystals comprised of an alkaline metal carbonate, an alkali metal bicarbonate, and an absorbent material and neural effects of a fragrance.
Other advantages and results of the invention are apparent from a following detailed description by way of example of the invention and from the accompanying drawings.
