BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to waste disposal bags and more particularly, it relates to new and improved plastic waste disposal or garbage bags which are not only capable of repelling small animals and insects in a safe manner, but are also substantially less visible and attractive thereto. The term "bags" includes sacks and the like, open or closed at either or both ends. [0003] 2. Related and Prior Art Statement [0004] There are many instances where the maintenance of a clean and sanitary home necessitates the disposal of the garbage, trash and waste which is generated within the home. Such trash, waste and garbage can include among other things, paper, dirty paper towels, spent tissues and disposable dishware and cutlery, used food wrappings and packaging, and lots and lots of food scraps left over from either breakfast, lunch, snacks and dinner. Such food scraps can include dairy products such as cheese and empty yogurt containers, leftover meats and fish, unfinished breads, cookies and cereals, and of course half eaten vegetables and fruits, including but not limited vegetable and fruit peels. [0005] The most common way of waste, trash or garbage removal and disposal consists of placing all the garbage, solid waste and trash in plastic garbage or trash bags and disposing of the bags when they become full. Thereafter, the garbage or trash bags are placed in garbage or trash cans, which in turn are placed curbside to be emptied into garbage trucks for ultimate carting and disposal away from the home. [0006] Often the garbage, solid or semi-solid waste, or trash generated by a home contains thing that other organisms, such as animals or insects, consider a perfect food. Such animals and insects include, among other things, rats, racoons, mice, cats, dogs, flies, wasps, etc., (hereinafter collectively "pests"). Thus, pests become very much attracted to the garbage that humans produce. First, they detect the garbage, waste or trash, i.e., with their sense of sight or smell or both, which in turn allows them to recognize the garbage as a viable food source. Then, via their sense of smell coupled with their vision, they will gravitate to the garbage and if the pests are small animals, tear open, or in some way breach the garbage bag and rummage through it to get to the recognized food. This in turn will create a mess and possibly unsanitary conditions in the area where the garbage or trash bag is placed. If on the other hand, the pests are insects then they will alight on the garbage, lay eggs, and begin the waste putrification process which will not only generate noxious fumes and unsightly garbage but can also lead to the spreading of disease from garbage to humans. [0007] The garbage, trash or waste disposal bags available on the market and commonly used in connection with the disposal of solid and semi-solid waste, garbage or trash are made of either white, black or green plastic of a particularly thin gauge. However, white, black or green trash bags are all visible to all pests, animal and insects alike. Furthermore, even the thickest of the commercially available bags will easily rip from a pest's serious gnawing, and pawing attention to it. Even worse however, is the fact that after putting the garbage bags on the street, they will often sit in the sun and the already semi-spent garbage, waste or trash within will start to heat up. Being hard to seal, these bags will start to let out a stench which will permeate the surrounding area and attract pests. Flies will alight on them and lay eggs and within no time maggots will start to eat the rotting garbage. Additionally, animals like cats, dogs and racoons will jump at the chance to rummage through it. [0008] One way of trying to keep pests away is by spraying the garbage or trash bags with some kind of chemical pesticide or repellant before placing them curbside. Pest repellents and insecticides are well known and very common. Hence, as was just stated herein above, individuals might try to solve the problem of pests rummaging through and making a mess of garbage, or alighting thereon, by taking an ordinary garbage bag and spraying it with, or in some way, applying thereon, on its outer surface a chemical pesticide or repellant. A good example of such a pesticide is the chemical known as "DEET." However, most chemical repellants, including "DEET," are toxic both to humans and to animals, and having to spray them onto filled garbage bags every time they are put curbside, can have very seriously negative and deleterious effects on an individual's health, as well as the health of curious pets. Moreover, "DEET" as well as many other commercial pesticides are only effective in repelling insects and do not act as a repellant to other common pest species such as racoons and cats. Finally, applying a pesticide or insecticide directly on the surface of the trash bag providesfor a totally ephemeral and short protection against animals and insects as the surface application of an insecticide or repellant will quickly rub off or wear off from use and exposure to the elements. [0009] The relevant and material prior art has tried to address the garbage and trash bag drawbacks set forth herein above, in various ways and with various devices. One example of improvements in the prior art that have tried to address these disadvantages is Foster et al., U.S. Letters Pat. No. 5,150,541 which discloses a device for killing insects consisting essentially of: (i) a toxin-containing 11 element, and (ii) a mesh covering for the toxin-containing element of (i), to protect nontarget organisms from contact with the toxin, the toxin-containing element comprising about 50% to 78% of the surface area, and the mesh covering comprising about 22% to 50%; and a method for killing insects by exposing them to contact with the described device. [0010] Another example is Ron et. Al. U.S. Letters Pat. No. 5,839,221, which discloses an insecticidal device having a panel of an insect attracting color, preferably yellow, and a spherical body of another color preferably red. The spherical body is capable of defusing a liquid which contains an insect attractant and is combined with the panel in a manner that they form together an essentially flat panel having hemispherical bulges formed by the spherical body. A specific panel, which can be used as a panel in the above device and can be used as an independent insecticidal device is also provided. [0011] Yet another example is Scott et. Al. U.S. Letters Pat. No. 3,771,254 directed to insecticide treated bags. The bags are primarily flexible plastic bags coated or impregnated with an organo-phosphorus insecticide, especially pirimiphos methyl. The pyrimiphos methyl has a vapor pressure at 20 degrees celsius in the range of 1.times.10.sup.-3-1.times.10.sup.-6 millimeters of mercury, and is used in an amount of 1 to 100 m.g. of the insecticide per square foot of bag surface. The pyrimiphos methyl is coated or impregnated onto the plastic bag by passing the bag film continuously through a bath of a solution or dispersion of the insecticide, and preferably in a lacquer or printing ink base, preceded by some treatment to make the plastics surface more retentive to lacquer or printing. [0012] Still another example is Bordenka et. al., U.S. Letters Pat. No. 3,767,785 directed to insect repellent articles. They comprise webs containing a class of insect repellent compounds. These webs in turn can be fabricated into clothing containers and packages or employed as components thereof, significantly lessening the possibility of insect invasions of the interior of the containers with attendant contamination of the contents. [0013] Yet a still further example is Clayton, Jr. U.S. Letters Pat. No. 6,076,678 directed to a tick repellant carcass bag kit for use by hunters in the field to decrease the possibility of deer tick infection. The carcass wrapping kit has a wrap cloth positioned within a hermetically sealed housing member, the wrap cloth being impregnated with a deer tick repellant prior to its positioning within the hermetically sealed housing member or while in the hermetically sealed housing member immediately prior to use by way of a fracturable ampule of vial within the hermetically sealed housing member containing the deer tick repellant. [0014] Still another example is Riley U.S. Letters Pat. No. 4,804,142 directed to pest repellent articles for use in connection with receptacles which have not been treated or impregnated. The pest repellent article is for dispensing a repellent composition to a receptacle or area to be protected is disclosed. It comprises an outer cover and an inner porous removable pest repellent composition carrier member. The repellent composition carrier is formed of a compact absorbent structure and is impregnated with a volatile pest repellent composition. The outer cover or envelope completely encloses the repellent composition carrier member and is formed of a flexible, puncturable, tearable material substantially impermeable to the repellent composition and the vapors thereof. The outer cover is releasably sealed about the inner porous pest repellent composition carrier member and can be opened to remove the inner porous repellent composition carrier member. The inner porous pest repellent composition carrier member is releasably sealed whereby the composition carrier member can be opened to release the volatile repellent composition carrier. [0015] Another example is Simpson, U.S. Letters Pat. No. 5,884,801 which discloses an improved trash bag having a sidewall forming a trash-receiving volume, and having an inside surface, an outside surface, and an opening. There is at least one adhesive patch on the inside surface of the trash bag for trapping insects that enter the bag. The adhesive patches preferably extend substantially around the interior of the bag, and are spaced sufficiently from the opening of the bag that when the bag is inserted into a trash container, at least some of the adhesive patches are inside the container. A removable protective cover can be provided on the adhesive patches for protecting the adhesive before the trash bag is used, but which can be removed to expose the adhesive when the trash bag is used. The patches are preferably made to attract insects, for example being of a contrasting color to the inside surface of the bag, having contrasting insect silhouettes, and/or including chemical attractants. [0016] A further example is Fitsakis, U.S. Letters Pat. No. 5,359,808 which discloses a trap bag for the extermination of insects and particularly of may-flies (olive fly, domestic fly, Cherry fly and Mediterranean fly) comprising a trap bag with an insecticide soaked surface, containing a water or water solution with insect attracting substances, insects being killed as they fall upon the toxic surface of this trap bag. The materials used in manufacturing this trap are such as to allow a slow, continuous and controlled evaporation of the substances contained therein, the service life of the trap bag being extended by periodically adding a water solution of the insect attracting substances. [0017] Yet a further example is Hill et. al. U.S. Letters Pat. No. 4,238,878 which discloses an insect trap comprising a chimney member adapted to allow a flow of air to be forced therethrough, a reservoir of insect attractant which under the influence of the flow of air is evaporated and borne as a stream of attractant vapor emanating from the chimney member into the surrounding atmosphere, and a tacky substance provided inside the chimney member which will trap flying insects lured therein by the stream of attractant vapor. [0018] Still another example is Rutledge et. al., U.S. Letters Pat. No. 4,976,062 which discloses a chemical barrier for rodents and/or reptiles including an elongated flexible, porous fabric tube 22 of a generally rope-like size, shape and flexibility contains a plurality of elongated bodies, 24, 26 . . . of granular repellent material 28. The bodies 24, 26 . . . are spaced from each other by short, generally repellent free gaps 30 within the tube 22 and the size of the granules 28 in each body is sufficiently large that they cannot pass through the fabric forming the tube 22. Barriers 32 at the gaps 30 prevent the entry of the repellent material 28 into the gaps and allow the tube 22 to be severed in the gaps 30 within spillage of repellent material 28. [0019] A final example is Jones, et. al. U.S. Letters Pat. No. 4,320,112 directed to a composition for pest repellent receptacles. The receptacle such as a plastic trash can or bag contains an insect and animal repellent for ridding areas containing the receptacles of annoying insects and for preventing animals from turning over or destroying the receptacles when full, avoiding unnecessary clean-ups. Preferably, the pest repellent is incorporated into the receptacle during the forming thereof. Effective amounts of naphthalene flakes and oil of citronella added in solid form to the synthetic resin forming the receptacle provides for the insect and animal repellent properties. [0020] All of the improvements set forth above and many others, both patented and unpatented, focus on changing and improving traditionally available garbage bags, trash bags and waste disposal bags through the addition of insect repellants, insecticides and devices that deliver insect repellants and insecticides thereto. However, the insecticides and the repellants are extremely toxic. For example, according to www.scorecard.com, a website used by a diverse audience, from teachers to health professionals to educate themselves about pollution problems, toxic chemicals and their properties, naphthalene flakes are widely known to be a toxic carcinogen, extremely hazardous to humans. It has both a human inhalation toxicity score and a human health risk screening score above the 75.sup.th percentile. This means that it is more toxic and hazardous to humans than over 75 percent of known hazardous chemical compounds. Additionally, it has a environmental health hazard in the 90.sup.th percentile. Therefore, if one were to use this on a regular basis, in connection with often used garbage bags, they would be exposing both themselves and the surrounding public, to grave health risks while at the same time introducing pollutants into the environment. [0021] More importantly however, is that the above prior art improvements, fail to completely keep pests, both animals, or insects, or both totally and completely away from the garbage cans. [0022] Traditionally, commonly used garbage bags, trash bags or waste disposal bags are black, green or white. Green, black or white are the only colors used primarily with trash bags due to the low production costs for bags having these colors, the high cost of generating custom colored trash bags and the fact that many of the other colors used in connection with trash bags are reserved for special types of bags. As for example, opaquely red bags are used exclusively for hazardous wastes and the special disposal thereof. However, these colors, i.e., green, black and white are known to be extremely attractive to many pests species, both animals and insects, because they are extremely visible and discernible to them (see for example Hill, et. al. U.S. Letters Pat. No. 4,283,878, col. 1, 1. 65-1. 69 stating " . . . . The outside of the enclosure is preferably a warm or dark color i.e. a brown, red, black or similar colors as such colors attract flying insects)." Thus, the bags' ability to repel because of the repellents, or to kill because of the insecticides is compromised by the counteracting attractive force of the color of the bags, visible to all pests. In other words, the bags' repelling ingredients repel the pests, but the bags' colors attract and hold them; a situation that can prove quite contradictory and ultimately hazardous, particularly if the repellents or insecticides have grown weak with time, thereby allowing the pests to be guided both by their vision of the bag and of their smell. [0023] Accordingly, there is a need for disposable garbage bags, trash bags, and waste management bags that are more successful in keeping pests, both animals, or insects, or both, away from the garbage cans through the use of environmentally and health friendly chemical compositions and the substantial diminution of the pests' ability to see the garbage bags or trash bags, or waste disposal bags.
