ABSTRACT:
FIELD OF THE INVENTION
The present invention generally relates to a simplified one step, single stage, biodegradable pesticide delivery system for administering pesticide materials to control and/or eliminate noxious insect infestations, and more particularly, this invention relates to a biodegradable pesticide delivery system that can be safely utilized by those who are not skilled in the art of controlling insect infestation.
The science of pesticide pathology is known to be highly complex, that utilizes compounds and substances which can be of a toxic nature, to thereby requiring special handling.
Due to these circumstances, numerous procedures have been developed by those skilled in the art which call for highly specialized programs of a complicated nature which can only be performed by technicians who have received a high degree of training.
Although procedures of the current art are reasonably effective, the capital cost of performing the services is extremely high due to labor intensive procedures by highly qualified personnel.
Therefore a system is needed that will not only utilize the advantages of current technology in the art, but will simplify the application of this technology, and bring it within reach of those not skilled in the art, so that they may safely implement the system effectively and efficiently without extensive training, and at a reasonable cost.
Furthermore, the system must be environmentally friendly and totally biodegradable. The Biodegradable Pesticide Delivery System of this invention fulfills all of these parameters.
BACKGROUND OF THE INVENTION
It is a well known fact that wood destroying insects and organisms such as for example, subterranean termites, are responsible for the destruction of vast quantities of wood used in construction, resulting in huge financial losses. It is estimated that subterranean termite damage alone approaches a billion dollars annually in the United States.
Typically, wood destroying insects such as subterranean termites, are prevalent over a wide range of climatic conditions, and are found to be active in both Northern and Southern regions.
Various types of devices have been known in the prior art for controlling or destroying these noxious insects. Current conventional procedures in the art for the treatment and control of these species and similar noxious insects is extremely difficult to apply and equally expensive to maintain after the initial application.
Also the eradication of for example a colony of subterranean termites, will not ensure there will be no emergence of a new colony at a later date.
It is therefore necessary to commit to an ongoing preventative maintenance program once the incumbent colony has been eliminated.
Furthermore, pesticide control procedures of the current art are generally performed by highly skilled personnel, due to the complex nature of the systems used. This increases the overall cost substantially to the user of such services.
It is also a fact that due to the nature of the chemical pesticides used to treat noxious insect infestation, and the complex manner in which they are applied, the general public are not permitted to buy most of these pesticide chemicals for their own use.
Treatment for noxious insect infestation involves numerous procedures such as the application of toxic soil pesticides, either by spraying, or drilling holes into either the ground, or even the structure to be protected itself and then injecting pesticides.
Another system utilized is the digging of trenches and the installation of physical insect barriers around the perimeter of the structure to be protected in combination with the use of pesticides.
Yet a further system is the installation of underground sensing stations, which are periodically monitored, and subsequently charged with pesticides either in bait or poison form, when insects are observed inside the monitored stations.
In addition, some systems require the installation of a network of perforated underground tubing through which a liquid pesticide is sprayed.
It is obvious that such procedures must be performed by highly trained technicians, which result in extremely expensive application and installation costs.
In addition, due to the complexity of these systems, they are not for sale to the general public as it is reasonable to believe that the general publics lack of expertise in the art which would result in substandard applications, with less than optimal results, and the possibility of environmental damage.
The costs of these current conventional systems as discussed above, is further increased by their ongoing maintenance procedures.
Additional re-treatment of pesticides have to be applied on a periodic or possibly annual basis, and a continuing maintenance program is necessary to monitor the results, due to the nature of the systems.
Furthermore, such maintenance procedures are usually only carried out by highly trained technicians and at a correspondingly high cost.
It is readily apparent that there is the need for a simplified system of controlling noxious insects which should be within the capability of those not skilled in the art to successfully implement and maintain and be able to purchase at a reasonable cost.
Also, due to the rapid deployment of noxious insects such as subterranean termites, it is advantageous to do a pre-emptive, preventative pesticide installation before termites and other noxious insects gain a foothold. This can be accomplished by the installation of the Biodegradable Pesticide Delivery System of this invention.
DESCRIPTION OF THE PRIOR ART
Prior U.S. Pat. No. 5,329,726, issued Jul. 19, 1994, discloses a SYSTEM FOR TERMITE DETECTION AND CONTROL, in which a perforated, and more or less permanent housing is deposited into the ground, and subjected to periodic inspections. Pesticides are placed into the housing upon indications of subterranean termite activity.
The prior patents cited and made of record, the above mentioned patents have been studied including the following patents which relate to this field of endeavor.
U.S. Pat. No. 1,013,514: January 1912
U.S. Pat. No. 2,837,861: June 1958
U.S. Pat. No. 3,017,717: January 1962
U.S. Pat. No. 3,940,875: March 1976
U.S. Pat, No. 4,945,673: August 1990
While the above discussed and listed patents relate to this field of endeavor, they do not disclose the pesticide delivery system described in this invention.
OBJECTS OF THE INVENTION
It is a primary objective of this invention to provide a highly effective, but simple system of delivering and administering pesticides in such a manner so as to be within the ability of those unskilled in this art to be able to safely, and efficiently install, and maintain a high level of protection from insect infestation with a minimum of training and at an economical cost.
Yet another objective of this invention also relates to the safe and efficient single stage administering of pesticide material, in either a poison, or a bait form, in either granular, solid, or liquid state, in order to control noxious insects and wood destroying organisms.
Once the pesticide delivery system of this invention at hand is installed, no further participation, or monitoring procedures are required to be performed on the installed units.
An additional objective of this invention is to make available a variety of ready to use pesticide delivery systems which have been preloaded by the pesticide manufacturers with a commercial type of pesticide such as for example, but not limited to, Dursban, or Hexaflumuron.
This would make available a wide variety of pesticide materials, according to regional requirements, the species of noxious insects to be controlled, and the choice of either a poison, or bait-type pesticide.
The preloading of the pesticide units of the pesticide delivery system would ensure the safe handling of these materials, many of which may be of a toxic nature.
This is so, because the user of the pesticide delivery system will have no actual physical contact with the preloaded pesticide materials and will have no opportunity to eithe
