Definitions
- the present invention relates to the monitoring and/or controlling of arthropods such as termites and, in particular, to devices that are placed in the ground and can be used to monitor and/or control populations of arthropods.
- Termites are well known throughout most areas of the world as insects that attack and destroy wooden structures. Subterranean termites most often enter structures from the surrounding soil to feed on wood or other cellulosic material of the structure and its contents. Many methods for killing termites have been employed over the years. One such method involves applying a toxicant ⁇ i.e., a material that kills or repels termites) to the soil in the vicinity of a structure that is to be protected from termites. Not only is this type of treatment labor intensive and raises issues about soil contamination, but the application may not produce an adequate barrier to termite infestation.
- a toxicant i.e., a material that kills or repels termites
- bait stakes for example, do not provide a continuous barrier around the structure, as they typically occupy limited area and, moreover, are separated from one another by a distance on the order of feet or even yards.
- Termite populations located in the soil can have difficulty locating the bait stakes in the first place, especially if the bait stakes are widely spaced and located on a predetermined interval irrespective of conditions around a structure conducive to termite attack, such as moist areas around a structure. Also, removal of the bait stakes can disrupt the system of passageways leading to the stake that termites may have constructed and, in turn, can disrupt the flow of termites to the stake upon stake re-insertion.
- Patents 5,329,726 and 5,555,672 both in the name of Thorne, et al, which disclose insertion into the ground of a stationary housing that not only contains a removable bait cartridge but also possesses a plurality of extensions which are said to intercept or obstruct the path of termites in the vicinity of the housing.
- U.S. Patent No. 5,950,356 discloses an apparatus and method wherein a non-toxic termite bait is fixedly attached to the sidewall of a housing and, upon inspection of the sidewall of the housing for termite activity, toxic bait is introduced into the interior of the housing. This method is said to avoid the disturbances inherent in the use of a system of interchangeable monitoring and bait cartridges.
- U.S. Patent No. 6,016,625 is said to disclose bait stations that contain a combination of stacked monitoring and baiting devices having an extractor means that can selectively move the termite monitoring and/or baiting devices.

- the plate can also comprise a material capable of being penetrated by arthropods, such as a polymeric foam.
- one or more plates 245 can be disposed between the members.
- the plates can have a length equal to or somewhat less than the length of the lateral wall of the housing and/or members.
- plate 245 has a length of at least about 66% of the length of the lateral wall of the housing.
- the plate is substantially rectilinear, but can have a variety of other shapes.
- the plate has a Y-shaped cross-section accommodating three (or more or fewer) members.
- the plate can, of course, have a different cross-section, such as one that has an X-shape so as to accommodate four (or more or fewer) members.
- the shape and cross-section of the plate can vary depending on the number of members utilized and/or the application desired.
- outer edge 248 between faces 251 and 252 of plate 245 conforms to the lateral wall of the housing 115.
- Plates of the type shown in Fig. 11 can be constructed from a corrugated or solid material such as wood, cardboard, paper, polymeric foam (including expanded and/or extruded polystyrene foam), polyethylene, plastics, or other synthetic polymers.
- plate 245 is constructed from a corrugated synthetic polymer having substantially hollow passageways 249 extending substantially throughout the plate's length.
- the plate or plates comprise a plurality of grooves 246 on a surface of the first and/or second face (not shown) of plate 245. These grooves 246 define at least one containment channel 246a.
- the grooves 246 can be of virtually any size and shape. While not wishing to be limited to any particular theory, the grooves 246 are believed to direct arthropods along containment channels 246a toward the members as well as from the members to the lateral wall 115 of the housing.
- the widths of the grooves preferably are about 0.03 inches to about 0.5 inches, and more preferably about 0.125 inches.
- the grooves may, for example, be of similar dimensions along their entire length, as with channel 246a, or may narrow (as with a slice of a pie) as one proceeds from the lateral wall 115 of the housing to the members, as with channel 246b.
- the plate 245 may comprises a plurality of ridges on a surface of the first and/or second face (not shown) of plate 245. These ridges may define at least one containment channel.
- the ridges can be of virtually any size and shape. While not wishing to be limited to any particular theory, the ridges are believed to direct arthropods along containment channels toward the members as well as from the members to the lateral wall 115 of the housing.
- the widths of the ridges preferably are about 0.03 inches to about 0.5 inches, and more preferably about 0.125 inches.
- the stations of the present invention comprise one or more sleeves, either inside or outside the housing.
- sleeve 250 can substantially conform to the exterior of lateral wall 115 of housing 200.
- a sleeve can substantially conform to the exterior of one or more of the members disposed within the housing.
- the sleeve can be formed of material capable of being consumed by arthropods, capable of being penetrated by arthropods, capable of being transported by arthropods, and/or capable of killing arthropods.
- the sleeve does not contain preformed openings to the housing 200 and/or to the members. Instead, the openings or tunnels through the sleeve 250 are formed by the arthropods themselves.
- the sleeve 250 has a thickness that is less than about 3.0% of the length of the lateral wall 115 of the housing.
- the present invention provides a PCO or other operator with various alternatives to monitor and/or control an arthropod population.
- the various members that can be disposed within the housing provide an operator with increased flexibility in treating any particular arthropod infestation situation.
- the use of multiple members also make it possible to provide a relatively large volume of monitoring and/or baiting material in response to heavy feeding conditions that will allow inspections to be conducted at extended intervals to save both time and money.
- the separate and independent configuration of the multiple members within the housing and the various functions each member can serve provide many alternatives for minimizing interruption and disturbance of arthropod feeding within the housing starting at the time of station installation and throughout the monitoring and/or controlling activities.
- one or more stations 100 are implanted in the soil, although such stations can be adapted for above-ground use.
- the station or stations are implanted in the soil within about 1-2 feet of a building, preferably one suspected of suffering from arthropod infestation. If two or more stations are implanted, the stations are generally located within 10 feet of one another.
- the station is implanted in the soil such that a portion of the lateral sidewall 115 of the housing extends above the soil.
- the lateral sidewall will extend to such a point above the soil that a PCO or other operator can locate the station and access the station without having to disrupt its position in the soil.
- the extension preferably is not at a height that would cause interference with a lawnmower or other above-ground devices.
- a PCO operator should be able to manipulate one of the end elements (e.g., 105) that is removably attached to lateral wall 115 so as to provide access to the interior portion 120 of the housing.
- an operator may remove the end element 105 by utilizing the locking mechanism depicted in Fig. lb.
- an operator from a standing position, may engage protrusion 105 a with cooperative member 106, thereby allowing the end element to be rotated and removed.
- the end element 105 may remain attached to the cooperative member 106 after removal due to engagement of protrusions on the cooperative member 106 (not shown) and recesses 101 of protrusion 105a to allow for easy replacement after inspection of the interior of the station is complete.
- the stations of the invention will be initially inspected for arthropod activity, especially in areas where arthropods have not previously been detected.
- end elements 211 of such members within the housing preferably are transparent to allow inspection of the interior without disruption of the member.
- the end element, such as 211, of the members can be removed from the lateral wall of the member to inspect the interior of the member.
- arthropod activity within the station will be evident from inspection of the material within the housing but exterior to the members, including inspection of monolithic mass 240, plate 245, protrusion 237, and/or sleeve 250.
- FIGS. 7 and 8 Use of the stations of the invention is exemplified by reference to FIGS. 7 and 8. It is to be understood, however, that other combinations and selective placement and replacement of members is contemplated within the scope of the present invention, as the flexibility offered by the present invention is one of its advantages. Indeed, the members and materials can be disposed in any sequential arrangement in the housing and the configurations shown in the drawings are merely exemplary. Referring to FIG. 7, embodiments involving three members are depicted. Initially, it is preferred that a station of the invention comprise members that serve a monitoring function. For example, in FIG.
- member 255 includes a wooden block within a member and two placeholder members 257, i.e., members that have no openings and an empty or solid interior, preferably made of an arthropod resistant material.
- member 255 may be combined with a member that can include water, pheromones, humectants, or other material attractive and/or nonrepellant to arthropods.
- Member 255 is periodically inspected for arthropod activity. Inspection is typically performed by inspecting for termite activity by looking through a transparent end element of the member or by removing a detachable end element of the member.
- one or more placeholder members 257 can be removed and replaced with a member 258 having a material capable of killing arthropods in its interior, i.e. a baiting member (see, e.g., FIGS. 7b and 7c).
- a baiting member e.g., FIGS. 7b and 7c.
- the end elements of baiting member 258 are permanently affixed to the lateral wall of member 258, particularly if the material capable of killing arthropods is hazardous to people and pets and/or if the material is otherwise deemed hazardous by environmental regulations or laws. In this manner, arthropods previously feeding or present within member 255 will be relatively undisturbed upon placement of a baiting member 258 within the housing to provide control of the arthropod population.
- two baiting members 258 can be inserted for two placeholder members 257 (FIG. 7c) or an additional baiting member, a fourth member, can also be disposed within the housing.
- FIG. 8 depicts embodiments wherein a wooden block (260) is employed as a member.
- a monitoring member 255 can be arranged with two placeholder members 257.
- the wooden block is removed and arthropods are tapped back into the empty member 255.
- the removed arthropods serve a recruitment function in that they will return to their nest and direct other arthropods to the station.
- the wooden block originally in member 255 may be discarded or placed in a new member 255 that can be used to replace a placeholder member 257.
- the station housing can initially contain one or more baiting members 258, particularly if detection is not a primary concern or if an area is known to be infested with arthropods.
- the members of the invention can be arranged in various combinations and substituted for one another depending on the particular arthropod infestation situation.
- the substitution of a member or the insertion of a member can be carried out without substantial disturbance to the arthropods already present within the station housing, especially with the use of placeholder members 257.
- the removal and/or insertion of one member can take place without disturbance to another member and the arthropods that can be present therein.
