The present invention relates to compositions to treat wood. More particularly, the present invention relates to compositions and methods for treating wood to control insects and more particularly, kill termites, while deterring and preventing termite infestations.
A pest is an organism which is detrimental to humans or human concerns. Pests include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (round-worms) and microbes.
Typically, pests are classified into insects, mites, nema-todes and gastropods.
Pesticides are substances or mixture of substances intended for preventing, destroying, repelling or mitigating any pest. A pesticide may be a chemical agent, a biological agent (such as a virus or bacterium), an anti-microbial, a disinfectant or a device used against any pest.
Pesticides are categorized into four main substituent chemicals: herbicides, fungicides, insecticides and bacteri-cides. Pesticides can be classified by target organism, chemical structure and physical state. Pesticides can also be classed as inorganic, synthetic, or biological (bio-pesticide). Bio-pesticides include microbial pesticides and biochemical pesticides. These include pyrethroids, rotenoids and nicoti-noids. Pesticides can also be classified based upon their biological mechanism function or application method. Most pesticides work by poisoning the pests.
An insecticide is a pesticide used against insects. They include ovicides and larvicides, used against the eggs and larvae of insects respectively. Insecticides are classified in several different ways. Typically, they are classified as systemic insecticides, contact insecticides, natural insecti-cides, plant-incorporated protectants (PIPS), inorganic insecticides and organic insecticides. The commonly known insecticides include: i) organochlorides such as DDT, aldrin, chlordane, chlordecone, heptachlor, methoxychlor, pen-tachlorophenol and the like; ii) organophosphates such as acephate, azinphos-methyl, bensulide, chlorethoxyfos, chlo-rpyrifos, diazinon, dimethoate, disulfoton, ethoprop, fenamiphos, parathion, trichlorfon and the like; iii) pyrethroids such as allethrin, bifenthrin, cyhalothrin, lambda-cyhalothrin, cypermethrin, cyfluthrin, prallethrin, transflu-thrin and the like, iv) carbamates such as aldicarb, bendiocarb, carbofuran, carbaryl, dioxacarb, fenobucarb, fenoxycarb, isoprocarb, methomyl and the like.
Commercially available insecticides, including those available for home use, commonly comprise active ingredients or poisons which are not only toxic to the target insect pests, but, if used in relatively confined environments and delivered as aerosol sprays, can be present in sufficient concentration to also be toxic to humans and household pets. Various undesirable side effects may include immediate or delayed neurotoxic reactions, and/or suffocation. Even the noxious odor of such materials can cause headaches or upset stomachs in some individuals. These adverse side effects are exacerbated when such compositions come in contact with persons of increased sensitivity, or persons of small body mass such as children or babies.
For some time, efforts have been made to develop insecticidal compositions, particularly those intended for residential use, which are effective in killing the targeted insect pests completely and quickly, but non-toxic to humans and pets. The Environmental Protection Agency (EPA) regulates the use of potentially toxic ingre-dients in pesticidal compositions under the Federal Insecti-cide, Fungicide and Rodenticide Act (FIFRA). Certain mate-rials considered to be either active or inert materials by the EPA have been deregulated or otherwise identified as accept-able safe substances under FIFRA offering minimum risk in normal use. Other materials are currently undergoing inves-tigation and may be deregulated in due course. Consumers generally consider deregulated substances non-poisonous or non-toxic. Thus, the term non-toxic or non-poisonous as used herein is intended to convey a compound or composition that, while highly effective in killing targeted insect pests, is safe to use around humans, particularly small children, and pets.
The search for a new repellent or termiticide is difficult because studies have shown that termites show unexpected sensitivity to chemicals, sensitivity that differs from that of other insects. For example, phenoxyethanol has been shown to be a trail-following substance; and naphthalene, a toxicant for most insects, was found to be used as fumigant by termites for their nests at concentrations that would kill fire ants, as disclosed in U.S. Pat. No. 5,874,097. That and other conventional compositions are disclosed in the following U.S. patents and U.S. patent Application Publications, which are incorporated herein by reference:
The following U.S. Publication Nos. are incorporated herein by reference:
While such conventional compositions and methods may be partly suitable for the particular purpose employed, they would not be as suitable for the purposes of the present invention as disclosed herein.

Illustrative embodiments of the present invention are described herein with reference to the accompanying drawings, in which like numerals throughout the figures identify substantially similar components, in which:
For a further understanding of the nature and function of the embodiments, reference should be made to the following detailed description. Detailed descriptions of the embodiments are provided herein, as well as, the best mode of carrying out and employing the present invention. It will be readily appreciated that the embodiments are well adapted to carry out and obtain the ends and features mentioned as well as those inherent herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, persons of ordinary skill in the art will realize that the following disclosure is illustrative only and not in any way limiting, as the specific details disclosed herein provide a basis for the claims and a representative basis for teaching to employ the present invention in virtually any appropriately detailed system, structure or manner. It should be understood that the devices, materials, methods, procedures, and techniques described herein are presently representative of various embodiments. Other embodiments of the disclosure will readily suggest themselves to such skilled persons having the benefit of this disclosure.
The advantages and significant benefits of the present invention include high solids, more film build, better flow, higher luster, when compared to conventional lacquers in performance without the toxicity. The present invention can be safely used by chemically sensitive users and has a mild odor content similar to citrus scent. The present invention fights indoor air pollution by sealing in off gassing and containing a very low volatile organic compound (VOC) content, which meets or exceeds all federal and state air quality regulations, including California's. Unlike many commercially available products the composition of the present invention contains no formaldehyde. The evaporation rate of the compositions of the present invention are slower than ether and have a vapor density that is heavier than air.
Therefore, in accordance with preferred embodiments of the invention there are provided insect repelling compositions of non-toxic wood preservatives that can be applied directly to the wood of a home's interior or exterior that are safe for pets and humans. The insect repelling compositions are able to deter, kill, and/or prevent insects from accessing wood which may serve as a food source for insects that come into contact with these compositions. According to inventors' research, the termite species termites subterranean excretes an alarm pheromone when exposed to a compound sourced from citrus fruit peels known as D-Limonene (C10H16). The d-isomer of limonene, a monoterpene and cycloalkene, occurs commonly in nature as the fragrance of oranges. The alarm pheromone excretion of termites is a natural defense mechanism of termites subterranean. Accordingly, when subterranean soldier termites detect danger in a location, these termites excrete the alarm pheromone to warn other termites of the danger, thereby, directing the other termites to avoid that location. When wood is treated with D-Limonene, the compound creates a zone of danger or discomfort perceived by wood boring insects, signifying to these insects that the zone is not inherently safe. The compositions of the present invention are believed to have long lasting effects, which deter and/or kill insects that come into contact with it, affecting a wide range of wood boring and eating insects, including termites, carpenter ants, and carpenter bees. The compositions of the present invention cause termite death, which result from destruction of the digestive and respiratory systems of termites. These compositions of the present invention are effective for many years and also assist with sealing outgassing.
Therefore, in accordance with embodiments of the invention there is provided a non-toxic insect control composition for treatment of a wood surface in interior and exterior settings. The composition of the present invention is preferably a clear, hard and durable, water-based acrylic compound. The composition includes D-Limonene, in a range of at least 5% to approximately 30% by weight, a non-toxic emulsifying agent, in a range of at least 1% to approximately 20% by weight, water in a range of at least 20% by weight to approximately 60% by weight of water, a modified acrylic emulsion copolymer in a range of at least 20% by weight to approximately 45% by weight, dipropylene glycol methyl ether in a range of at least 1% by weight to approximately 10% by weight, Polysiloxane Polymer in a range of at least 1% by weight to approximately 5% by weight, and an Amine solution in a range of at least 1% by weight to approximately 5% by weight. The D-Limonene can be derived from a variety of citrus fruits and other plants and is commercially available under the name Cold Pressed Orange Oil, for example. The non-toxic emulsifying agent can be, for example, Alkamuls® EL620. The composition preferably includes each of the above ingredients, though including the D-Limonene is highly preferred. D-Limonene, otherwise known as orange limonene or 1-methyl-4-(1 methylethenyl) cyclohexene, or 4-ispropenyl-1-methyl cyclohexene, has a chemical formula of C10H16, a molecular weight of 136.2, and contains 88.1% C and 11.8% H by weight. It occurs in various ethereal oils, particularly in oils of lemon, orange, lime, grapefruit and bergamot. D-Limonene can be cold pressed from citrus peels or obtained from steam extraction of citrus peels of, for example, orange, lemon, grapefruit, lime, and bergamot. Some extractions from citrus peels contain as high as 95% D-Limonene. Distillation of the oils produces technical grades of D-Limonene of higher purity from approximately 95% to approximately 96%.
In one embodiment, the non-toxic insect control composition preferably includes at least one food-grade preservative, such as sodium benzoate in a range of at least 0.1% to approximately 1% by weight.
In an exemplary embodiment of the present invention, a composition is provided comprising approximately 25% by weight cold pressed orange oil component, having a concentration of at least 90% D-Limonene, and approximately 75% by weight acrylic lacquer component, with the acrylic lacquer component comprising approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution.
The modified acrylic emulsion copolymer, dipropylene glycol methyl ether, polysiloxane, amine solution and water are mixed first, then Alkamuls® E1-620, water, and D-Limonene are mixed next. Once mixed, the composition remains homogenous for at least 180 days. When separation occurs, simple stirring is sufficient to cause the composition to become homogenous again. The D-Limonene is sourced from, for example, cold pressed orange oil preferably containing over 95% D-Limonene concentration, which is sold, for example, under the brand Medina®. The modified acrylic emulsion copolymer is sold, for example, under the brands Gellner Industrial, Golden Artist Colors®, and Holbein®. The dipropylene glycol methyl ether is sold, for example, under the brands Quality Chemical™, TCI America, DOW Chemical Company. The polysiloxane polymer is sold, for example, under the brands Golden Artist Colors®, Holbein®, Haisun®. The amine solution is sold, for example, by Amine Solutions Inc., Grainger Inc., Salt-X®. The 25% and 75% solutions of the composition can be applied to unpainted raw wood. In such embodiments of the invention, the composition dries completely in approximately 4 hours in dry environments and a second coat is then applied. Once the second coat dries the painted wood retains the aromatic citrus smell for at least 6 months.
Another exemplary embodiment of the present invention includes a composition having 30% Cold Pressed Orange Oil and 70% Acrylic Lacquer solutions. In such exemplary embodiment, the Cold Pressed Orange Oil component of the composition includes at least 80% by weight of D-Limonene, sold, for example, under the Home & Garden® brand from Green Gobbler™ Company. In such embodiment, the Acrylic Lacquer component includes at least 10% by weight of water; at least 50% by weight of modified acrylic emulsion copolymer, sold, for example, under the brands Gellner Industrial, Golden Artist Colors®, and Holbein®, at least 6% by weight of dipropylene glycol methyl ether, sold, for example, under the brands Quality Chemical™, TCI America, DOW Chemical Company, at least 3% by weight of polysiloxane polymer, sold, for example, under the brands Golden Artist Colors®, Holbein®, Haisun®, and at least 5% by weight of amine solution, sold, for example, by Amine Solutions Inc., Grainger Inc., Salt-X®. The modified acrylic emulsion copolymer, dipropylene glycol methyl ether, polysiloxane, amine solution and water are mixed first, then Alkamuls® El 620, water, and D-Limonene are mixed. Once mixed, the composition remains homogenous for at least 180 days. When separation occurs, simple stirring is sufficient to cause the composition to become homogenous again.
In exemplary embodiments of the present invention, a composition includes 30% and 50% solutions. The 30% solution of the composition includes approximately 4% by weight of D-Limonene, approximately 3% by weight of Alkamuls® El 620, known as cold pressed Castor Oil, approximately 20% by weight of water, approximately 60% by weight of modified acrylic emulsion copolymer, approximately 4% by weight of dipropylene glycol methyl ether, approximately 4% by weight of polysiloxane polymer, and approximately 5% by weight of amine solution.
In such exemplary embodiment, the modified acrylic emulsion copolymer, dipropylene glycol methyl ether, polysiloxane, amine solution and water are mixed first, then Alkamuls® El 620, water, and D-Limonene are mixed.

To evidence the unexpectedly improved nature of the results obtained using embodiments of the claimed invention, the foregoing tests were performed. The following examples are intended to exemplify the claimed invention, and not to limit the claimed invention in any manner.
To demonstrate the effectiveness of a termicidal composition in accordance with embodiments disclosed herein, an experiment was conducted to evaluate treated cellulose material for its resistance to subterranean termites the American Wood Protection Association (AWPA) Standard E1-13 was implemented. In the experiment, single choice tests and two choice tests were performed simultaneously. The experiment tested wood treated with one embodiment of the claimed invention against Formosan subterranean termites, Coptotermes formosanus, as the targeted insect. The experiment was conducted utilizing the embodiment of the invention containing the insect repelling composition which includes approximately 25% by weight cold pressed orange oil component having a D-Limonene concentration of at least 80%, and approximately 75% by weight acrylic lacquer component, with the acrylic lacquer component comprising approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution. Five replications were made for each of the following treatments:
The wood specimens to be tested are allowed to air dry for one week and are then weighed. Sterilized glass jars are filled with 150 g of sand and 30 ml of distilled water. The sterilized glass jars are allowed to stand for two hours. For the single choice tests, a solitary test block is placed on the sand surface. For the two choice test, two different types of wood blocks, a treated wood block and a control wood block, are placed on opposite sides of the jar. A piece of aluminum foil is placed under each treated wood block to prevent leaching of the embodiment of the present invention into the sand.
Termites were collected from the field from the West End neighborhood in the city of New Orleans, Louisiana. The average weight of the collected termites were measured, as illustrated in Table 1 below. Four hundred termites, consisting of 380 worker termites and 20 soldier termites, were placed inside each test jar. These jars were maintained at 28° C. and 80% relative humidity (RH) for four weeks.

Each jar is weighed weekly to ensure moisture level is maintained. At the end of the four weeks, test jars are disassembled.
Each block is removed, cleaned with a brush, and allowed to air dry before weighing, as shown in Table 2 below.
The number of live termite workers and soldiers are determined for each test jar, as shown in Table 3 below.
Each test block was visually rated using the rating system defined in the AWPA E1 Standard below:
The following Table 2 illustrates the weights of test blocks before and after being exposed to Formosan subterranean termites.
For the single choice tests, the average weight consumed of the control, untreated, wood was 0.919 g, while that of the wood treated with one coat of the composition was 0.416 g and the wood treated with two coats of the composition was 0.330 g. Testing revealed that there was a statistically significant difference in the amount of untreated wood consumed and the amount of treated wood consumed (P=0.005). However, there was not a significant difference in wood consumption between the wood blocks treated with one coat and the wood blocks treated with two coats of the composition.
The experiment revealed that there was a significant difference between wood consumption (P=0.008) for the two choice test. Termites consumed significantly more of the untreated wood blocks than the wood blocks treated with two coats of the composition. As seen in
Table 3 illustrates the test jar weights taken throughout the study and the numbers of live termites in each jar at the beginning of the study and at the end of the study.
Based on jar weights, the experiment revealed that the test jars did not lose enough moisture during this study to warrant the addition of any more water.
The experiment revealed that there was a significant difference in termite mortality among treatments (P<0.001). Analysis of variance (ANOVA) was performed following a Tukey Test to rank treatments, as illustrated in Table 4, which utilized pairwise multiple comparisons between treatments. The treatments tested in this experiment which are ranked with the same letter showed no significant differences in termite mortality.
This experiment indicated that the compositions disclosed herein, in accordance with embodiments of the invention, are highly effective at repelling termites from wood treated with such disclosed compositions, and the disclosed compositions significantly increased the average mortality rates of the exposed populations of termites in comparison to untreated wood samples. The single choice wood blocks treated with two coats of the composition resulted in termites only consuming on average 6.764% of the wood blocks and killed approximately 51.4% of the termites. The single choice wood blocks treated with one coat of the composition resulted in termites only consuming on average 10.164% of the wood blocks and killed approximately 36.75% of the termites. In comparison, the single choice untreated, control wood blocks resulted in termites consuming 30.114% of the wood blocks and only 11.95% of the termites died. Under the two choice test, approximately 25.15% of the termites died and while the termites consumed on average 21.392% of the untreated, control wood blocks, only 2.852% of the two coat treated wood blocks were consumed.
To further evaluate the effectiveness of termiticidal compositions disclosed herein in accordance with embodiments of the invention, an additional experiment was conducted to evaluate treated cellulose material for its resistance to subterranean termites and to compare conventional termiticide to the compositions, in accordance with embodiments of the invention. The American Wood Protection Association (AWPA) Standard E1-13 was implemented. In the experiment, single choice tests and two choice tests were performed simultaneously. The experiment tested wood samples treated with four different compositions, of which three of the compositions were provided in accordance with embodiments of the invention disclosed herein, and the fourth composition was the conventional BORA-CARE® termiticide composition produced by Nisus Corporation. The tested wood samples were treated with a Treatment Y, a Treatment X, a Treatment B, and a Treatment BC, for use against Formosan subterranean termites, Coptotermes formosanus, as the targeted insect.
The experiment was conducted utilizing the following treatments:

The composition included approximately 25% by weight cold pressed orange oil component having a D-Limonene concentration of at least 80%, and approximately 75% by weight acrylic lacquer component, with the acrylic lacquer component comprising approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution.
Treatment X, includes coating the wood with a composition, in accordance with embodiments of the present invention, which includes approximately 25% by weight cold pressed orange oil component having a D-Limonene concentration of at least 95%, and approximately 75% by weight acrylic lacquer component, with the acrylic lacquer component comprising approximately 45% by weight modified acrylic emulsion copolymer, at least 40% by weight water, at least 5% by weight dipropylene glycol methyl ether, at least less than 5% by weight polysiloxane polymer, and at least less than 5% by weight amine solution.
Treatment B, includes coating the wood with a mixture of Treatment X and approximately 25%, by weight pure boric acid (in power form).
Treatment BC, includes coating the wood with the conventional termiticide BORA-CARE®.
Five replications were made for each of the following treatments:
The wood specimens to be tested are allowed to air dry for at least one week and are then weighed. Sterilized glass jars are filled with 150 g of sand and 30 ml of distilled water. The sterilized glass jars are allowed to stand for two hours. For the single choice tests, a solitary test block is placed on the sand surface. For the two choice test, two different types of wood blocks, a wood block treated with Treatment BC and a wood block treated with Treatment X, are placed on opposite sides of the jar. A piece of aluminum foil is placed under each treated wood block to prevent leaching of the embodiments of the present invention into the sand.
Termites were collected from the field from the Elysian neighborhood in the city of New Orleans, Louisiana. The average weight of the collected termites were measured, as illustrated in Table 1 below. Four hundred termites, consisting of 360 worker termites and 40 soldier termites, were placed inside each test jar. These jars were maintained at 28° C. and 80% relative humidity (RH) for four weeks.

Each jar is weighed weekly to ensure moisture level is maintained. At the end of the four weeks, test jars are disassembled. Each block is removed, cleaned with a brush, and allowed to air dry before weighing, as shown in Table 2 below.
The number of live termite workers and soldiers are determined for each test jar, as shown in Table 4 below.
Each test block was visually rated using the rating system defined in the AWPA E1 Standard below:
The following Table 2 illustrates the weights of test blocks before and after being exposed to Formosan subterranean termites.
For the single choice tests, the average weight consumed of the control, untreated, wood was 0.835 g, while that of the wood treated with Treatment Y of the composition was 0.309 g, the wood treated with Treatment B of the composition was 0.200 g, the wood treated with Treatment BC of the composition was 1.496 g, and the wood treated with Treatment X of the composition was 0.356 g. Testing revealed that there was a statistically significant difference in the amount of untreated wood consumed and the amount of treated wood consumed (P<0.001).
Analysis of variance (ANOVA) was performed following a Tukey Test to rank treatments for the Single choice tests, as illustrated in Table 3 below, which utilized pairwise multiple comparisons between treatments. The treatments tested in this experiment which are ranked with the same letter showed no significant differences in termite mortality.
As seen in
As seen in Table 3 above, the effectiveness of Treatment BC (consisting of the conventional termiticide BORA-CARE®) at repelling termites and preventing said termites from consuming the wood blocks is significantly less effective than treatments utilizing embodiments of the present invention.
Table 4 illustrates the test jar weights taken throughout the study and the numbers of live termites in each jar at the beginning of the study and at the end of the study.

The experiment revealed that there was a significant difference in termite mortality among treatments (P<0.001). Analysis of variance (ANOVA) was performed following a Tukey Test to rank treatments, as illustrated in Table 5, which utilized pairwise multiple comparisons between treatments. The treatments tested in this experiment which are ranked with the same letter showed no significant differences in termite mortality.
This experiment indicated that the compositions of the present invention are effective at repelling and killing termites from treated wood samples. The compositions, in accordance with embodiments of the present invention, are significantly more effective at repelling termites and nearly or just as effective at killing termites as compared to conventional termiticides.
As seen in the data set forth in Example 1 and Example 2 above, the embodiments of the present invention identified herein offer a safe and effective method for controlling termite infestations. Further, the treatment processes described herein provide effective use as termite repellents, termiticides, and wood preservatives. The treatment processes may also be used with effectiveness for protection from other wood boring insects.
To the extent there may be perceived health or environmental concerns with existing termite repellents, termiticides, and wood preservatives, the ability to replace or reduce the amount of toxic termiticides and toxic wood preservatives by use of the present invention offers additional benefits as well. The non-toxic nature of the present invention makes embodiments of the invention ideal candidates for preventing, and treating termite infestations in both household and commercial settings.
The compositions of the present invention can be utilized on wooden surfaces, preferably unfinished or properly prepared and sanded previously finished wooden surfaces. All surfaces should preferably be clean and free from dirt, dust, grease, wax oil, silicone, tsp/soap, mill scale, oxidation, loose peeling paint or varnish, or any foreign matter/contaminants. The compositions of the present invention should be applied where there is adequate ventilation.
The compositions of the present invention may cause mild irritation to the eyes, skin, and respiratory tract. Therefore, users are advised to use the correct personal protective equipment (PPE) when handling the compositions of the present invention.
Referring to the following methods, after wood is treated with one or more of the compositions disclosed herein in accordance with embodiments of the invention, the treated wood is preferably dried in an arid environment with little to no humidity. One skilled in the art can appreciate that increased levels of humidity would cause an increase in the amount of time required for the treated wood to completely dry.
In accordance with embodiments of the invention, there is provided a preferred method of treating wood for use in interior and exterior settings with an insect repelling composition. In such embodiment, before applying the insect repelling composition to wood, a user should mix the composition thoroughly, preferably by gently stirring the composition, or by rolling a container housing said composition, in an effort to avoid air bubbles. Preferably, the composition should be stirred thoroughly for approximately 20 minutes prior to application. The preferred method comprises applying the insect control composition to at least one wood surface of a piece of wood by painting the composition onto the at least one wood surface, for example, with a quality nylon brush or pad applicator. In such preferred embodiment, the user uses the brush or pad to apply liberal coats of the composition to the at least one wood surface, while avoiding over brushing and keeping the brush or pad saturated with the composition. Preferably, the user applies a first coat of the composition to the at least one wood surface to a point of surface saturation. Then, the method preferably includes waiting approximately 6-24 hours to allow the composition of the first coat to completely dry. Once the composition applied to the at least one wood surface is substantially or completely dry, the user applies a second coat of the composition to the at least one wood surface to a point of surface saturation. The method further includes waiting an additional approximately 6-24 hours to allow the composition of the second coat to completely dry.
In one embodiment, the user adds water the composition to achieve desired consistency before applying the first coat.
In another preferred embodiment, there is provided a method of treating a piece of lumber with a wood preserving insect repelling composition. In one embodiment, for example, a preferred wood preserving insect repelling composition comprises 25% cold pressed orange oil having a D-Limonene concentration of at least 80% (and more preferably of at least 90%, and most preferably of at least 95%) and 75% acrylic lacquer.
