Field of Invention
[0002] This invention relates to increasing soil or wood moisture to encourage termites to tunnel and/or trail to termite detectors or a toxicant. Using recruitment compositions, soil or wood treatment compositions, systems, devices, and methods for using 2-phenoxyethanol or 2-phenoxyethanol+potassium salt, dissolved in water. The application of correct concentrations of solutions, dependent on soil types, forms a hygroscopic termite barrier around a wood containing structure and between termite bait and monitoring stations. in order to lead termites to termite toxicants, bait stations and/or monitoring stations.
Background and Prior Art
[0003] 2-phenoxyethanol is a solvent that mimics the trail pheromone of termites. It is found as a solvent in ballpoint pens, and also is used in food and cosmetics. Termites have been known to follow the ink trail for at least 50 years.
[0004] Greg Henderson and his colleagues (Jian Chen and Roger Laine identified the trail pheromone mimic in pen ink as 2-phenoxyethanol. (Chen, J, G. Henderson, and R. Laine, 1998. Isolation and Identification of 2-phenoxyethanol from ballpoint pen ink as a trail-following substance of Coptotermes formosanus and Reticulitermes. J. Entomological Science 33:97-105
[0005] Greg Henderson et al. at LSU patented 2-phenoxyethanol applications to baits to specifically kill termites (patent is attached), but not soil treatments of the trail pheromone mimic to allow discovery and mortality of termites as part of a total program. See U.S. Pat. No. 6,352,703 to Henderson et al. issued Mar. 5, 2002, which is incorporated by reference.
[0006] There is a patent on the use of the natural trail pheromone (dodecatrianol) for termite detection and control (see U.S. Pat. No. 5,024,832), but not for using 2-phenoxyethanol.
[0007] A May 2022 Thesis by L. Prescott, discussed, the use of 2-phenoxyethanol as a trail pheromone soil treatment to lead termites to pop-up termite detection stations. The project showed that termites will feed more on cellulose material surrounded by the treatment and in the field the treatment will lead them to detection stations (5 of 20 2-phenoxyethanol soil-treated stations hit, compared to 0 of 20 that were not treated. See Prescott, Luke, Master's Thesis for Soil Tunneling/Tubing by Subterranean Termites in Response to 2-phenoxyethanol, Department of Entomology and Nematology, University of Florida, May 2022.
[0008] Other scientists have discovered that termites detect and follow salts in soils that leach from logs as they decay. See Botch and Judd., Effects of Soil Cations on the Foraging Behavior of Reticulitermes flavipes (Isoptera: Rhinotermitidae). Ecology and Behavior, Journal of Economic Entomology, Vol. 104, No. 2, pages 425-435, April 2011. Potassium cations were the only ones to attract termites.
[0009] Scientists have also found that salts in sports drinks are followed by termites. These salts can include potassium salts that mimic the salts that leach from logs. We have hypothesized that by combining 2-phenoxyethanol and potassium salt, termites will reliably follow the trail to detection traps or termite treatments. See Cornelius et al., Efficacy of Bait Supplements for Improving the Rate of Discovery of Bait Stations in the Field by Formosan Subterranean Termites (Isoptera: Rhinotermitidae), Journal of Economic Entomology, Vol, 102, no. 3, pages 1175-1181, 2009.
[0010] The prior art ignores the fact that 2-phenoxyethanol is not closely related to the natural trail pheromone of termites, dodecatrianol. Glycols like 2-phenoxyethanol and potassium chloride or carbonate absorb moisture from the air or surrounding soil. Termites are, therefore, following an elevated water holding trail of high soil/wood moisture rather than a pheromone trail. Termites orient to high moisture and will follow soil/wood of elevated water content.
[0011] The prior art also applied a single concentration of 2-phenoxyethanol to the soil, ignoring the fact that some soils/wood (e.g., sand or pine) is more porous than other soils (e.g., clay or oak). Porosity of wood/soil is important because no single concentration of an applied product can provide the necessary high water content needed to affect termite behavior. Termites prefer to be in moist rather than dry soils, so they will follow a trail of high water content soil for detection or control. Therefore, the application of a single concentration of 2-phenoxyethanol and/or potassium salt to different soil types cannot deliver the correct amount of 2-phenonxyethanol and/or potassium salt to a volume of treated soil.
[0012] Also, there was no previous study that included 2 hygroscopic products, like 2-phenoxyethanol and potassium salts, to change the physical nature of soil/wood so water in the treated area has a higher water content than the surrounding soil/wood. No previous study has documented that the physical water holding nature of soil can be used to affect termite behavior.
[0013] No previous patent has demonstrated that surrounding a structure containing wood with a hygroscopic soil/wood treatment will lead termites to bait or toxicants and protect the structure from termite attack.
Thus, the need exists for solutions to the above problems with the prior art.
Summary of the Invention
[0014] A primary objective of the present invention is to increase the physical water holding capacity of soil to direct termites to toxicants and/or detection devices using recruitment compositions, systems, devices, and methods that include between approximately 0.1% to approximately 2.0% of 2-phenoxyethanol dissolved in water, so the termites will reliably follow a higher soil water trail to termite toxicants, monitoring stations, and/or bait stations.
[0015] A secondary objective of the present invention is to provide variable application percentages and rates of stations. 2-phenoxyethanol and/or potassium salts dissolved in water, to form an elevated water holding trail for different soil types (sand, sandy & silty soil, Loam and clay soil) leading to termite toxicants, termite bait stations, and/or termite monitoring stations.
[0016] A third objective of the present invention is to provide a complete barrier around a structure so termites will be redirected due to elevated soil water concentrations that connect termite toxicants, monitoring stations and/or bait stations arranged about a perimeter of a wood containing structure.
[0017] A preferred embodiment of the termite trailing and recruitment system, comprises:
-
- [0018] a plurality of termite bait and monitoring stations positioned about a wood-containing structure; and
- [0019] a trail of 2 phenoxyethanol (2-PE) applied to soil between each of the termite bait and/or monitoring stations, wherein each trail directs termites away from the wood-containing structure to an individual termite bait and/or monitoring station.
[0020] The 2 phenoxyethanol (2-PE) ranges from approximately 0.1% to approximately 2% depending on the soil type and localized conditions.
[0021] The 2 phenoxyethanol (2-PE) is approximately 0.1% dissolved/suspended in water as the trail for sand soil.
[0022] The 2 phenoxyethanol (2-PE) is approximately 0.2% dissolved/suspended in water as the trail for sandy and silty soil.
[0023] The 2 phenoxyethanol (2-PE) is approximately 0.4% dissolved/suspended in water as the trail for loam soil.
[0024] The 2 phenoxyethanol (2-PE) is approximately 2% dissolved/suspended in water as the trail for clay soil.
[0025] The trail is approximately 10 to approximately 20 feet between each of the termite bait and/or monitoring stations.
[0026] The termite bait and monitoring stations are located up to approximately 10 to approximately 20 feet apart from one another in a perimeter about the wood-containing structure.
[0027] The 2 phenoxyethanol (2-PE) ranges from approximately 0.1% to approximately 2% depending on the soil type and localized conditions, and the trail is approximately 10 to approximately 20 feet between each of the termite bait and/or monitoring stations.
[0028] The 2 phenoxyethanol (2-PE) ranges from approximately 0.1% to approximately 2% depending on the soil type and localized conditions, and the termite bait and monitoring stations are located approximately 10 to approximately 20 feet apart from one another in a perimeter about the wood-containing structure.
[0029] A method for trailing and recruiting termites to termite bait and monitoring stations, comprises the steps of:
[0030] providing a plurality of termite bait and monitoring stations positioned about a wood-containing structure; and applying a trail of a percentage 2 phenoxyethanol (2-PE) dissolved/suspended in water to soil located between each of the termite bait and monitoring stations, wherein each trail leads termites away from the wood-containing structure to an individual termite bait and/or monitoring station.
[0031] The percentage 2 phenoxyethanol (2-PE) dissolved in water ranges from approximately 0.1% to approximately 2% depending on the soil type and localized conditions.
[0032] The 2 phenoxyethanol (2-PE) is approximately 0.1% dissolved/suspended in water as the trail for sand soil.
[0033] The 2 phenoxyethanol (2-PE) is approximately 0.2% dissolved/suspended in water as the trail for sandy and silty soil.
[0034] The 2 phenoxyethanol (2-PE) is approximately 0.4% dissolved/suspended in water as the trail for loam soil.
[0035] The 2 phenoxyethanol (2-PE) is approximately 2% dissolved/suspended in water as the trail for clay soil.
[0036] The trail is approximately 10 to approximately 20 feet between each of the termite bait and/or monitoring stations.
[0037] The termite bait and monitoring stations are located up to approximately 10 to approximately 20 feet apart from one another in a perimeter about the wood-containing structure.

[0084] Testing of the novel termite trailing and recruitment compositions took place at the New Orleans Mosquito, Termite and Control District in New Orleans, Louisiana from Jun. 16 to Jun. 20, 2023.
[0085] The objective of the tests was to determine which prepared formulation of composition product most attracts and induces feeding behavior in Formosan subterranean termites.
Species:
[0086] For this protocol, individuals from a single colony of Formosan subterranean termites, Coptotermes formosanus, were used. Termites were collected from previously established field collection crates in New Orleans. This study was initiated within 3 days of termite collection.

[0094] A total of 60 replicates were performed for this study.
Arena Setup:
[0095] 2-D termite foraging arenas consisting of two clear acrylic plates (24 cm×24 cm) separated by spacers and were secured together with bolts. Each arena contained moistened sand and filter paper circles. The sand around each paper filter circle was treated with the pre-designated treatment.
[0096] To assemble each arena, first the top plate was placed face-down and moistened with distilled water using a spray bottle. Two pieces of filter paper (55 mm diameter) were placed directly onto the top plate. These two pieces of filter paper were placed in such a way as to be equidistant from the release chamber and from the sides. Filter papers were approximately 10 cm from the release chamber and approximately 5 mm from the arena sides. Sand was scattered over this plate, and excess sand was leveled off using a straight edge. The sand surface was misted again with distilled water using a spray bottle to the point of being damp without any runoff. A treated trail of pre-designated product was then pipetted on the sand around the circumference of the filter paper circles at a rate of approximately 0.18 ml/cm. For each replicate, the location of Treatment A and Treatment B alternated. The bottom plate was then secured to the top of the arena and flipped over.
Filter Paper:
[0097] Filter paper used in this study was approximately 55 mm in diameter. It was oven dried at approximately 120° C. for approximately 2 hours and weighed prior to placing them in each arena. It was dried, cleaned, and weighed again at the conclusion of this study, after being exposed to termites for 4 days.
Bioassay:
[0098] 500 Formosan subterranean termites consisting of a 10% soldier ratio (450 workers:50 soldiers) were placed into the release chamber of each of the 60 replicates and the lid placed on the release chamber. Arenas were maintained in an environmental chamber at 28° C. and 80% RH for 4 days. At that time, arenas were disassembled, and filter paper collected, cleaned of sand residue, dried, and weighed.
Data Collection:
[0099] The following data points were collected for each replicate:
-
- [0100] 1. Treatment A filter paper dry weight before termite exposure
- [0101] 2. Treatment A filter paper dry weight after termite exposure
- [0102] 3. Weight of filter paper consumed (Treatment A)
- [0103] 4. Percent consumption for Treatment A filter paper
- [0104] 5. Treatment B filter paper dry weight before termite exposure
- [0105] 6. Treatment B filter paper dry weight after termite exposure
- [0106] 7. Weight of filter paper consumed (Treatment B)
- [0107] 8. Percent consumption for Treatment B filter paper
[0108] FIG. 3 is a graph showing the average percent of paper consumption from termites with the novel trailing and recruitment compositions in the invention. The results teach us that 2-PE and 2-PE+KCl increased termite activity and the percentage of paper consumption significantly when soil around the termite food source was treated.
[0109] FIG. 4 is a graph showing the average mg of paper consumption with the novel trailing and recruitment compositions in the invention. The results teach us that 2-PE and 2-PE+KCl increased termite activity and the mg of paper consumption significantly when soil around the termite food source was treated.
Results:
[0110] Completed data sheets of each arena were compiled after 4 days of termite activity.
[0111] Analysis of variance (ANOVA) followed by post-hoc Tukey test using SigmaPlot (Systat Software, Inc.) yielded a significant difference in weight of filter paper consumed across all treatments (H=16.751, df=3, P<0.001). TABLE B below shows differences between treatments:
[0112]
| TABLE B | |
|---|---|
| Mean Weight Consumed (g) + SD. | |

| 2Pe 0.1% | |
| Composition according | 0.0419 + 0.0266 C |
| to the invention: 2PE + | |
| K2CO3 0.05% | |
| Composition according | 0.0723 + 0.0424 AB |
| to the invention: 2PE + | |
| KCl 0.05% | |
| Water | 0.0462 + 0.0361 BC |
[0113] From this data analysis, it can be determined that termites fed more on filter paper surrounded by the Composition according to the invention 2Pe 0.1% and Composition according to the invention 2Pe+KCl 0.05% than any other treatment, and there was not a significant difference in feeding between these two aforementioned treatments. Termites even preferred Composition according to the invention 2Pe 0.1% to water as well, though there was no such preference Composition according to the invention 2Pe+KCl 0.05% over water. Termites did not feed significantly more on filter paper surrounded by Composition according to the invention 2Pe+K2CO3 0.05% when compared to any other treatment.
[0114] The trials prove that termites consume more treated filter paper media when 2Pe and 2Pe+KCl are present around the paper. The amount consumed is almost twice as much as untreated controls (H2O).
[0115] FIG. 5 is a diagram layout view of a house structure with termite monitoring or bait stations arranged about the perimeter, A along with a surface applied continuous Phenoxyethanol trail C connecting between each of the termite monitoring or bait stations. B. FIG. 5 is a diagram of connecting monitoring or bait stations B around a house perimeter A with a continuous connecting trail C to prevent termites from tunneling between stations B.
[0116] Referring to FIG. 5 , the house structure A, can include a wood frame and/or siding (wood-containing structure), and can have a footprint of approximately 30 feet wide by approximately 50 feet long. Each of the termite monitoring or bait stations B can be spaced approximately 20 feet apart from one another spaced outside the footprint A of the wood containing structure. The surface applied continuous connecting trail C between termite monitoring or bait stations B, together form a closed loop perimeter spaced outside footprint A of the wood containing structure. Each continuous connecting trail directs termites away from the wood-containing structure and directly to an adjacent one of the individual termite monitoring or bait stations.
[0117] The preferred spacing between monitoring or bait stations is approximately 10-20 ft.
[0118] Between each of the termite monitoring or bait stations B, can be a trail of Phenoxyethanol or 2Pe+KCl for connecting the stations to one another. The trail C can lead termites to the termite monitoring or bait stations B, and away from the structure A.
[0119] TABLE C is a table of the Variable application rates of 2 phenoxyethanol (2-PE) based on soil type. Concentration of dilution applied varies from approximately 0.1% to approximately 2.0% depending on soil conditions. Total water to move 2-PE into the ground remains constant.

[0121] Table C shows the variable application rates for 4 soil types, which includes Sand, Sandy & silty soil, Loam, and Clay soil.
[0122] The infiltration rates for the four (4) soil types in Table C are from the published water infiltration rates which have support from Table 3 of the Soil Infiltration Brochure, Guides for Educators, May 2014 published by the United States Department of Agriculture, National Resources Conservation Service (NRCS) Guides for Educators, May 2014, seven pages. The infiltration rates are from a textbook. It is “Introduction to Soil Physics” by Daniel Hillel, 1982 Academic Press, 392 pages.
[0123] The infiltration rates provide a guide to the general permeability of soil types on which to assess the necessary concentration and volume if 2-PE and KCl and/or K2CO3.
[0124] In order to have the product not pool on the soil surface and spread out rather than percolate into the soil, we have varied the percentage of 2-PE in the application volume to deliver the same amount of 2 phenoxyethanol per 10 linear feet to the different soil types. To compensate for the lower amounts of water for the soils that have lower water infiltration rates, we have calculated the amount of water that should be used to irrigate the soil and move the treatment down to the position of subterranean termites below the soil surface. The concentrations recommended go from approximately 0.1% to approximately 2%. A concentration of approximately 0.08 to approximately 0.2% could be used.
[0125] Various Soil Treatment Methods will now be described.
[0126] Sandy Soil Treatment Method. A treatment with the current invention could be applied to sandy soil in the following manner. Monitoring/bait stations would be placed in the sandy soil around a structure and spaced approximately 20 ft apart. In a spray tank, A volume of 15.14 ml of 2Pe would be added for every 10 ft to be treated to connect the stations. The water would be added to the spray tank to achieve 4 gallons of total solution per 10 linear ft or 0.1% solution. The 4 gallons of 0.1% solution would be poured or sprayed onto the soil surface to create an uninterrupted line between the bait/monitoring stations. No additional water would be added to the treatment line The solution would wet the soil to a depth of 2-6 inches where termites actively tunnel. The termites would then follow the treated line to the bait/monitoring stations.
[0127] Sandy Silty Soil Treatment Method. A treatment with the current invention could be applied to sandy silty soil in the following manner. Monitoring/bait stations would be placed in the sandy silty soil around a structure and spaced approximately 10-20 ft apart. In a spray tank, A volume of 15.14 ml of 2Pe would be added for every 10 ft to be treated to connect the stations. The water would be added to the spray tank to achieve 2 gallons of total solution per 10 linear ft or 0.2% solution. The 2 gal of 0.2% solution per 10 linear ft would be poured or sprayed onto the soil surface to create an uninterrupted line between the bait/monitoring stations. After applying the 2Pe solution, 2 gal of water per 10 linear ft would be applied to the treated line in order to slowly move the treatment vertically into the soil profile without horizontal runoff. The solution would wet the soil to a depth of 2-6 inches where termites actively tunnel. The termites would then follow the treated line to the bait/monitoring stations.
[0128] Loam Soil Treatment Method. A treatment with the current invention could be applied to loam soil in the following manner. Monitoring/bait stations would be placed in the loam soil around a structure and spaced approximately 10-20 ft apart. In a spray tank, A volume of 15.14 ml of 2Pe would be added for every 10 ft to be treated to connect the stations. Water would be added to the spray tank to achieve 1 gallon of solution per 10 linear ft or 0.4% solution The 1 gallon of 0.4% solution would be poured or sprayed onto the soil surface to create an uninterrupted line between the bait/monitoring stations. After applying the 2Pe solution, 3 gal of water would be applied to the treated line in order to slowly move the treatment vertically into the soil profile without horizontal runoff. The solution would wet the soil to a depth of 2-6 inches where termites actively tunnel. The termites would then follow the treated line to the bait/monitoring stations.
[0129] Clay Soil Treatment Method. A treatment with the current invention could be applied to clay soil in the following manner. Monitoring/bait stations would be placed in the clay soil around a structure and spaced approximately 10-20 ft apart. In a spray tank. A volume of 15.14 ml of 2Pe would be added for every 10 ft to be treated to connect the stations. The water would be added to the spray tank to achieve 0.2 gallon of total solution per 10 linear ft or 2% solution. The 2% solution would be poured or sprayed onto the soil surface to create an uninterrupted line between the bait/monitoring stations. After applying the 2PE solution, a volume of 3.8 gal of water would be applied to the treated line in order to slowly move the treatment vertically into the soil profile without horizontal runoff. The solution would wet the soil to a depth of 2-6 inches where termites actively tunnel. The termites would then follow the treated line to the bait/monitoring stations.
[0130] The Benefits for the use of 2-PE and KCl and/or K2CO3 in soil include:
-
- [0131] 1. Enhanced termite detection capability with the use of monitoring devices with a reduction in time to detection due to directed termite training behavior.
- [0132] 2. Reduction of pesticide use when used in conjunction with termite bait systems that contain toxicants within matrixes and tamper-resistant stations.
- [0133] 3. Reduction of risk for termite damage to wood-containing structures by directing termites away from structures and into termite bait and/or monitoring stations.
