Rodenticide

Abstract

A rodenticide composition is described along with a method for using the same to exterminate rodents. The composition features a mixture of a dehydrant for causing dehydration in a rodent, a water-absorbent, hygromorphic carrier for absorbing water and expanding after consumption by the rodent, and a flavoring composition. The carrier can be a source of cellulose or a non-cellulosic material. After consumption of the composition by a rodent, the dehydrant and carrier cause the rodent to experience dehydration. The rodenticide composition may also include an irritant that causes digestive stress to the rodent, which further stresses and dehydrates the rodent. Once the rodenticide composition is prepared, it may be placed in areas frequented by or infested with rodents so as to kill the rodents once they consume the composition. One or more flavorings, coloring agents, and weather resistant materials may also be added to the composition.

Those skilled in the art will readily appreciate that the detailed description given herein is for explanatory purposes as the invention extends beyond these limited embodiments. For example, in light of the teachings of the present invention, those skilled in the art will recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein beyond the particular implementation choices in the following embodiments described and shown. That is, numerous modifications and variations of the invention exist that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.

[0054] The present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications, described herein, as these may vary. The terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. As used herein and in the appended claims, the singular forms a, an, and the include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to an element is a reference to one or more elements and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to a step or a means is a reference to one or more steps or means and may include sub-steps and subservient means.

[0055] All conjunctions used herein are to be understood in the most inclusive sense possible. Thus, a group of items linked with the conjunction and should not be read as requiring that each and every one of those items be present in the grouping, but rather should be read as and/or unless expressly stated otherwise. Similarly, a group of items linked with the conjunction or should not be read as requiring mutual exclusivity among that group, but rather should be read as and/or unless expressly stated otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise.

[0056] Unless otherwise defined, all terms (including technical and scientific terms) are to be given their ordinary and customary meaning to a person of ordinary skill in the art, and are not to be limited to a special or customized meaning unless expressly so defined herein.

[0057] Terms and phrases used in this application, and variations thereof, especially in the appended claims, unless otherwise expressly stated, should be construed as open ended as opposed to limiting. As examples of the foregoing, the term including should be read to mean including, without limitation, including but not limited to, or the like; the term having should be interpreted as having at least; the term includes should be interpreted as includes but is not limited to; the term example is used to provide exemplary instances of the item in discussion, not an exhaustive or limiting list thereof; and use of terms like preferably, preferred, desired, desirable, or exemplary and words of similar meaning should not be understood as implying that certain features are critical, essential, or even important to the structure or function of the invention, but instead as merely intended to highlight alternative or additional features that may or may not be utilized in a particular embodiment of the invention.

[0058] Those skilled in the art will also understand that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the appended claims may contain usage of the introductory phrases at least one and one or more to introduce claim recitations; however, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles a or an limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases one or more or at least one and indefinite articles such as a or an (e.g., a and an should typically be interpreted to mean at least one or one or more); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of two recitations, without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to at least one of A, B, and C is used, in general, such a construction is intended in the sense one having skill in the art would understand the convention (e.g., a system having at least one of A, B, and C would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to at least one of A, B, or C is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., a system having at least one of A, B, or C would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).

[0059] All numbers expressing dimensions, quantities of ingredients, reaction conditions, and so forth used in the specification are to be understood as being modified in all instances by the term about unless expressly stated otherwise. Accordingly, unless indicated to the contrary, the numerical parameters set forth herein are approximations that may vary depending upon the desired properties sought to be obtained.

[0072] Indoor and outdoor test trials were conducted using one or more embodiments of the rodenticide composition as described in Examples 1 and 2 above.

[0073] Indoor Trial

[0074] Prior to treatment using the rodenticide composition, all likely food sources were removed from the indoor testing site. Samples of the rodenticide composition were placed in locations of the indoor testing site where fresh signs of rodent activity were found, e.g., fresh droppings. Sixty grams of the rodenticide composition of Example 1 was placed into each of several small feed trays spaced approximately 36 inches apart throughout the infested indoor area. Activity and mortality was examined by counting dead or moribund species found within 10 feet of the feed trays over a 10-day period. After five days, no fresh droppings were found and three rodent carcasses had been collected. Two of the carcasses were of the common house mouse (Mus musculus) and one carcass was of the common brown rat (Rattus norvegicus).

[0075] Outdoor Trial

[0076] Samples of the rodenticide composition were placed in locations of the outdoor testing site fresh signs of rodent activity were found, e.g., fresh droppings and near burrows, runways, feeding places, and at points of entry around the perimeter of a utilized building. Sixty grams of the rodenticide composition of Example 2 were placed in open shallow feed trays or wrapped in cling film and placed in drainpipes, open-ended boxes, or under sheets of metal/wood secured at an angel against a wall (to keep the product dry) at intervals of approximately two yards (72 inches reducing to approximately 1.5 yards in areas of suspected high infestation). Activity and mortality was examined by counting dead or moribund species found within 20 feet of the feed trays over a 10-day period. After six days a dramatic decrease in fresh droppings was recorded and seven rodent carcasses had been collected. Three of the carcasses were of the common house mouse (Mus musculus), three carcasses were of the common brown rat (Rattus norvegicus), and one carcass was of the common deer mouse (Peromyscus maniculatus).

[0077] The invention also features a method that can be used to exterminate rodents. In a first step of the method, a rodenticide composition, as described herein above, that includes a mixture of a natural dehydrant and a natural carrier matrix, wherein the natural carrier matrix features a cellulosic composition that is grain-based, nut-based, legume-based, or starchy tuber-based, is prepared. Once the rodenticide composition has been prepared, in a next step of the method, an amount of the rodenticide composition sufficient to kill a rodent is placed in an area in which the extermination of rodents is desired, wherein the rodent is killed after consuming the rodenticide composition.

[0078] The invention also provides a rodenticide composition that includes a composition for producing endogenous gas and a method for using the same to exterminate rodents. The rodenticide composition includes a mixture of: a dehydrant, a composition for producing endogenous gas, a dietary emulsifier, and a source of cellulose. In the most exemplary embodiments, the rodenticide composition will also include a hypercalcemia promoter. In other exemplary embodiments, the rodenticide composition can include one or more irritants as ingredients. In some embodiments, the rodenticide composition can also include a flavoring, a weathering agent, or both.

[0079] The dehydrant of the rodenticide is a composition or ingredient that causes a rodent to experience dehydration after it is consumed. Hygroscopic desiccant materials are useful as dehydrants in the rodenticide due to their ability to absorb water from their surroundings (in this case, water in the rodent's digestive system).

[0082] The composition for producing endogenous gas of the rodenticide composition is an alkali carbonate, a peroxide, yeast, a combination of two or more of the foregoing, or any other suitable material derived from any of the foregoing. Once ingested by a rodent, the composition for producing endogenous gas produces oxygen as the endogenous gas. The endogenous gas causes bloating, discomfort, and digestive stress that decreases the rodent's desire to eat, which further dehydrates the rodent and hastens death. The rodenticide's composition for producing endogenous gas is a composition selected from among: sodium percarbonate, magnesium percarbonate, zinc percarbonate, calcium peroxide, calcium percarbonate, magnesium peroxide, zinc peroxide, sodium perborate, potassium monopersulfate, tetraacetylethylenediamine, yeast, any other suitable composition or ingredient for producing endogenous gas, a combination of two or more of the foregoing, or any other suitable material derived from any of the foregoing. In certain exemplary embodiments, the composition for producing endogenous gas can be one or more naturally occurring compositions or ingredients. In other embodiments, the composition for producing endogenous gas can be one or more artificial or manmade compositions or ingredients. In still other embodiments, the composition for producing endogenous gas can be a mixture of one or more naturally occurring compositions or ingredients and one or more artificial or manmade compositions or ingredients.

[0083] In preferred embodiments of the rodenticide composition, the composition for producing endogenous gas is selected from among calcium percarbonate, calcium peroxide or both. In the most preferred embodiments of the rodenticide composition, the composition for producing endogenous gas is calcium percarbonate.

[0084] The composition for producing endogenous gas may be included in the rodenticide composition in a percentage by weight of about 2% to about 10%.

The rodenticide composition can include the composition for producing endogenous gas in a percentage by weight of about a lower limit to about an upper limit, wherein the lower limit is a percentage by weight selected from the foregoing percentages by weight and the upper limit is a percentage by weight selected from the foregoing percentages by weight that is higher than the lower limit. In a preferred range, the rodenticide composition can include the composition for producing endogenous gas in a percentage by weight of about 2% to about 10%.

In an exemplary embodiment, the composition for producing endogenous gas can be included in the composition at about 6% of the composition by weight.

[0085] The dietary emulsifier is a composition that disrupts the gut microbiota in rodents and promotes colitis and metabolic syndrome. The initial dietary stress caused in the rodent after consumption of the dietary emulsifier contained in the rodenticide reduces the rodent's desire to feed and increases dehydration and hastens death. The rodent's intestine is protected from its microbiota via multi-layered mucus structures that cover the intestinal surface, thereby allowing the vast majority of gut bacteria to be kept at a safe distance from epithelial cells that line the intestine. Agents that disrupt mucus-bacterial interactions can promote diseases associated with gut inflammation. Common food-grade emulsifiers can readily disrupt mucus-bacterial interactions in rodents leading to gut inflammation. Low concentrations of one or both of these two commonly used food grade emulsifiers, carboxymethylcellulose and polyoxyethylene (20) sorbitan monooleate, induce low-grade inflammation and metabolic syndrome in wild-type rodent hosts and promoted robust colitis in mice predisposed to this disorder. Further, polyoxyethylene (20) sorbitan monooleate produces mild to moderate depression of a rodent's central nervous system with a marked reduction in locomotor activity and causes both ataxia and paralytic response.

[0086] The dietary emulsifier of the rodenticide composition is carboxymethylcellulose, polyoxyethylene (20) sorbitan monooleate, both, any other suitable dietary emulsifier, or any other suitable material derived from any of the foregoing. In the most preferred embodiments of the rodenticide composition, the composition for producing endogenous gas is polyoxyethylene (20) sorbitan monooleate.

[0087] The dietary emulsifier may be included in the rodenticide composition in a percentage by weight of about 0.25% to about 5%. For example, the dietary emulsifier may be incorporated into the rodenticide composition in about 0.001, 0.005, 0.009, 0.01, 0.015, 0.019, 0.02, 0.025, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.095, 0.099, 0.1, 0.101, 0.105, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.195, 0.199, 0.2, 0.201, 0.205, 0.21, 0.22, 0.225, 0.23, 0.24, 0.241, 0.245, 0.249, 0.25, 0.251, 0.255, 0.26, 0.27, 0.275, 0.28, 0.29, 0.291, 0.295, 0.299, 0.3, 0.31, 0.32, 0.325, 0.33, 0.34, 0.35, 0.36, 0.37, 0.375, 0.38, 0.39, 0.4, 0.41, 0.45, 0.49, 0.5, 0.51, 0.55, 0.59, 0.6, 0.7, 0.75, 0.8, 0.9, 0.91, 0.95, 0.99, 1, 1.01, 1.1, 1.2, 1.25, 1.3, 1.4, 1.5, 1.6, 1.7, 1.75, 1.8, 1.9, 1.95, 1.99, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.95, 3.99, 4, 4.01, 4.05, 4.09, 4.1, 4.15, 4.19, 4.2, 42.25, 4.3, 4.4, 4.5, 4.6, 4.7, 4.75, 4.8, 4.9, 4.95, 4.99, 5, 5.01, 5.05, 5.09, 5.1, 5.2, 5.25, 5.3, 5.4, 5.5, 5.6, 5.7, 5.75, 5.8, 5.9, 5.91, 5.95, 5.99, 6, 6.1, 6.5, 7, 8, 9, or 10 percent by weight. The rodenticide composition can include the dietary emulsifier in a percentage by weight of about a lower limit to about an upper limit, wherein the lower limit is a percentage by weight selected from the foregoing percentages by weight and the upper limit is a percentage by weight selected from the foregoing percentages by weight that is higher than the lower limit. In a preferred range, the rodenticide composition can include the dietary emulsifier in a percentage by weight of about 0.25% to about 5%. In a most preferred range, the rodenticide composition can include the dietary emulsifier in a percentage by weight of about 0.5% to about 3%. In an exemplary embodiment, the dietary emulsifier can be included in the composition at about 1% of the composition by weight.

[0088] The hypercalcemia promoter of the rodenticide composition causes long-term hypercalcemia by increasing calcium levels in the blood. Hypercalcemia further causes elevated arterial blood pressure and increased cardiac muscle contraction, which leads to polyuria and dehydration that eventually cause death. The hypercalcemia promoter also causes digestive stress and metabolic disorder in the short term, which reduces the rodent's desire to eat, thereby increasing dehydration and hastening death of the rodent.

[0089] The hypercalcemia promoter of the rodenticide composition is selected from among: calcium carbonate, calcium glycerate, calcium citrate, calcium lactate, calcium gluconate, a calcium uptake enhancer, bone meal, any other suitable source of a hypercalcemia promoter, a combination of two or more of the foregoing, or any other suitable material derived from any of the foregoing. The calcium uptake enhancer can be selected from among: cholecalciferol, ergocalciferol, L-lysine, L-Valine, L-tryptophan, any other suitable calcium uptake enhancer, a combination of two or more of the foregoing, or any other suitable material derived from any of the foregoing. Some embodiments of the rodenticide composition may not include a hypercalcemia promoter.

[0090] In preferred embodiments of the rodenticide composition, the hypercalcemia promoter is a combination of calcium carbonate and cholecalciferol. In the most preferred embodiments of the rodenticide composition, the hypercalcemia promoter is a combination of calcium carbonate, cholecalciferol, and L-lysine.

[0091] The hypercalcemia promoter may be included in the rodenticide composition in a percentage by weight of about 0.05% to about 4%. For example, the hypercalcemia promoter may be incorporated into the rodenticide composition in about 0.001, 0.005, 0.009, 0.01, 0.015, 0.019, 0.02, 0.025, 0.03, 0.035, 0.039, 0.04, 0.041, 0.042, 0.0425, 0.043, 0.044, 0.045, 0.046, 0.047, 0.0475, 0.048, 0.049, 0.0491, 0.0495, 0.0499, 0.05, 0.0501, 0.0505, 0.0509, 0.051, 0.052, 0.0525, 0.053, 0.054, 0.055, 0.056, 0.057, 0.0575, 0.058, 0.059, 0.0591, 0.0595, 0.0599, 0.06, 0.061, 0.065, 0.069, 0.07, 0.08, 0.09, 0.095, 0.099, 0.1, 0.101, 0.105, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.195, 0.199, 0.2, 0.201, 0.205, 0.21, 0.22, 0.225, 0.23, 0.24, 0.241, 0.245, 0.249, 0.25, 0.251, 0.255, 0.26, 0.27, 0.275, 0.28, 0.29, 0.291, 0.295, 0.299, 0.3, 0.31, 0.32, 0.325, 0.33, 0.34, 0.35, 0.36, 0.37, 0.375, 0.38, 0.39, 0.4, 0.41, 0.45, 0.49, 0.5, 0.51, 0.55, 0.59, 0.6, 0.7, 0.75, 0.8, 0.9, 0.91, 0.95, 0.99, 1, 1.01, 1.1, 1.2, 1.25, 1.3, 1.4, 1.5, 1.6, 1.7, 1.75, 1.8, 1.9, 1.95, 1.99, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.95, 3.99, 4, 4.01, 4.05, 4.09, 4.1, 4.15, 4.19, 4.2, 42.25, 4.3, 4.4, 4.5, 4.6, 4.7, 4.75, 4.8, 4.9, 4.95, 4.99, 5, 5.01, 5.05, 5.09, 5.1, 5.2, 5.25, 5.3, 5.4, 5.5, 5.6, 5.7, 5.75, 5.8, 5.9, 5.91, 5.95, 5.99, 6, 6.1, 6.5, 7, or 8 percent by weight.

[0113] Rodenticide Composition

[0114] A rodenticide composition useful for exterminating rodents (i.e., mammals that are species of the order Rodentia) is described along with a method for using the same to exterminate rodents. In some embodiments, the rodenticide can be produced using all-natural ingredients, and therefore, is non-toxic and safe if contacted or consumed by humans and other animals. Exemplary embodiments of the composition are produced using no synthetic ingredients. In other embodiments, the rodenticide composition can be manufactured using synthetic ingredients or a combination of synthetic and natural ingredients. In all exemplary embodiments, whether they include synthetic ingredients or not, the rodenticide composition is non-toxic if ingested and safe if contacted by humans or animals.

[0115] The rodenticide composition features a mixture of a dehydrant for causing dehydration in a rodent; a water-absorbent, hygromorphic carrier for absorbing water and expanding after consumption by the rodent; and a flavoring composition. A hygromorphic carrier is a composition or material that changes in size, shape, or both when exposed to water or moisture, for example, as in the digestive system of a rodent. In most embodiments, the carrier is hygroexpansive meaning that it expands upon contact with water or moisture. The carrier can be a source of cellulose or a non-cellulosic material. After consumption of the rodenticide composition by a rodent, the dehydrant and carrier cause the rodent to experience dehydration and the carrier expands within the digestive system to cause digestive or gastric pain, discomfort, or stress, to prevent the composition from being passed out of the bowels of the rodent by defecation, and in some cases, to cause internal damage to the rodent due to enlargement of the composition within the rodent's digestive system. As explained elsewhere herein, most species of rodents are unable to vomit, and once the composition is consumed, the rodent is unable to pass the expanded composition out of its body due to the hygroexpansive nature of the carrier, which expands and changes size within the rodent's gut. These characteristics of the composition may also cause bowel obstruction or starvation of the rodent as it is unable to consume additional food. Due to the effects caused by its ingredients, as a whole, the rodenticide composition is water-absorbent (and thus, dehydrating) and hygromorphic (and more particularly, hygroexpansive).

[0116] The rodenticide composition may also include one or more irritants (such as those described elsewhere herein) that causes digestive stress to the rodent, which further stresses and dehydrates the rodent. Irritants that are used in exemplary embodiments of the rodenticide composition described hereafter include citric acid, calcium carbonate, coffee grounds, and combinations of two or more of the foregoing. One or more coloring agents and weather resistant materials may also be added to the rodenticide composition.

[0117] In exemplary embodiments, the water-absorbent, hygromorphic carrier is a source of cellulose or a source of chitin. The rodenticide composition can include a single carrier or two, three, four, five, or more carriers. In more exemplary embodiments, the carrier is a source of alpha cellulose. In some exemplary embodiments, the carrier includes both a source of cellulose and a source of chitin. In other embodiments, the carrier is a non-cellulosic composition, substance, or material that also does not contain chitin, e.g., fish meal. In still other embodiments, the rodenticide composition includes a carrier that includes both a cellulosic carrier and a non-cellulosic carrier such as, for example, a carrier that includes alpha cellulose and mushroom or a carrier that includes alpha cellulose and fish meal. Examples of suitable cellulosic carriers include a grain-based cellulosic composition, a nut-based cellulosic composition, a legume-based cellulosic composition, a starchy tuber-based cellulosic composition, cellulose fibers, carboxymethyl cellulose, cardboard, cellulose acetate, regenerated cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, methylcellulose, pectin, sodium carboxymethyl cellulose, cornmeal, corn grits, corn cobs, corn gluten meal, any other suitable source of cellulose, a combination of two or more of the foregoing, or any other suitable material derived from any of the foregoing. Examples of non-cellulosic, non-chitin carriers useful for inclusion in the rodenticide composition, either alone or in combination with other cellulosic or chitin-containing carriers, include fish meal, a meat-based cat food, a fish-based cat food, or a combination of two or more of the foregoing. In embodiments that include a cat food, a fish-based cat food is preferred over a meat-based cat food. Some embodiments of the rodenticide composition may include one or more carriers described elsewhere herein.

[0118] The source of chitin used as or as part of a carrier of the rodenticide composition can be portabella, shiitake, another mushroom, another fungus, derivatives of any of the foregoing, or a combination of two or more of the foregoing. The source of chitin can be fungal or non-fungal in origin.

[0119] In the most exemplary embodiments of the composition, the carrier is corn cobs, fish meal, or both. In an exemplary embodiment that is preferred, the carrier includes a mixture of a source of alpha cellulose (preferably corn cobs) and fish meal.

[0120] The rodenticide composition can include a single dehydrant or two, three, four, five, or more dehydrants. Examples of compositions, substances, and materials suitable for use as or as part of the dehydrant of the rodenticide composition include a grain-based cellulosic composition, a nut-based cellulosic composition, a legume-based cellulosic composition, a starchy tuber-based cellulosic composition, activated alumina, aerogel, benzophenone, bentonite clay, calcium chloride, calcium sulfate, caramel, cellulose fibers, cobalt (II) chloride, copper (II) sulfate, ethanol, glycerol, honey, lithium bromide, lithium chloride, magnesium perchlorate, magnesium sulfate, methanol, perlite, potassium carbonate, potassium hydroxide, silica, silica gel, fumed silica, sodium, sodium chlorate, sodium chloride, sodium hydroxide, sucrose, sulfuric acid, vermiculite, zinc chloride, any other suitable dehydrant, a combination of two or more of the foregoing, or any other suitable material derived from any of the foregoing. In exemplary embodiments, the dehydrant is sodium chloride or perlite. Some embodiments of the rodenticide composition may include one or more dehydrants described elsewhere herein.

[0121] Some carriers described herein also act as dehydrants while some dehydrants described herein also function as carriers.

[0122] In more exemplary embodiments of the composition, the dehydrant is cellulose (including, for example, cellulose fibers), a silica compound (including, for example, silica gel), perlite, a chloride compound (including, for example, sodium chloride), sucrose, or a combination of two or more of the foregoing. In the most exemplary embodiments of the composition, the dehydrant is sodium chloride, perlite, or both. In another very exemplary embodiment, the dehydrant is cellulose, sodium chloride, perlite, or a combination of two or more of the foregoing.
