The present invention relates in general to crawling pest control systems and, in particular, to devices and methods for capturing or treating crawling insect pests such bed bugs and the like.
Bed bug control has become increasingly difficult while the prevalence of the species in homes, hotels/motels and other businesses has simultaneously reached crisis levels. The concept of trapping bed bugs and other crawling insects is presently generally regarded as a way of early detection and monitoring of the pests. Currently, however, it is not suitable for controlling and remediating existing problems.
An advantage exists, therefore, for traps that can inhibit and possibly prevent bed bug and other crawling insect infestation by intercepting the pests as they are newly introduced into an environment in order to prevent their feeding and subsequent egg laying.
A further advantage exists for traps suitable for detecting low levels of pest populations following pesticide treatment as a means to confirm that the population has been effectively eliminated.
A further advantage exists for traps that can be used to detect locations of isolated populations of crawling pests to pinpoint particular treatment needs for reducing the pest population.
The present invention provides pest control systems that incorporate interception means to impede the forward movement of bed bugs or similar pests and cause them to interact with trapping means or treatment means. When bed bugs or similar pests move along a surface (on any plane) their movement can be slowed or deterred when they encounter an intercept wall or surface extending generally perpendicularly to the plane on which they are traveling. The effect of the intercept wall may be further enhanced by use of a substantially smooth guide surfaces. Guide surfaces can be created by means of substantially smooth means such as smooth tape or smooth surfaces joined to a trapping or treatment device. When bed bugs or other crawling pests come into contact with a smooth surface, they either cannot traverse it or will experience difficulty in doing so. This causes the pests to follow the path of least resistance and cling to the more textured surface that they are already traversing. The intercept wall according to the invention is preferably placed in the direct path of the transition line between the roughened or textured surface and the smoother guide surface(s) and forces the pests to interact with a trap or treatment zone that is placed on or near the intercept wall. Thus, the intercept wall provides a means to improve the likelihood that the bed bugs interact with the trapping or treatment device. Without such an intercept wall, most bed bugs and like pests can easily walk past a pest control device without interacting with it.
The systems and methods according to the invention function to guide bed bugs from a large area into a confined treatment or trapping device, with or without the use of attractants such as CO2, heat, pheromones and/or kairomones.
Non-limiting uses for the instant technology include:
The disclosed invention also provides for point source pesticide treatments to be placed in the direct path of bed bugs or similar pests. Through the disclosed methods of guide surfaces and interception walls, bed bugs and like pests that are foraging over a large area can be funneled into a small space that is treated with a contact pesticide so that very small amounts of pesticides can be used to treat bed bugs over a very large area.
Other details, objects and advantages of the present invention will become apparent as the following description of the presently preferred embodiments and presently preferred methods of practicing the invention proceeds.
The invention will become more readily apparent from the following description of preferred embodiments thereof shown, by way of example only, in the accompanying drawings wherein:
The following definitions and discussion of general principles are offered to provide context for the subsequent detailed description of preferred embodiments of the invention.
As used herein, “substantially smooth surfaces” or words of similar effect shall mean surfaces that, when placed vertically, substantially vertically or facing downwardly, bed bugs or similar crawling pests cannot traverse. Bed bugs and like pests can walk across the smoothest surfaces when placed substantially horizontally, however they will not generally cling to such surfaces (regardless of their orientation). Thus, when given the choice between smooth or textured surfaces, even when placed horizontally, crawling pests will choose to follow the textured surface.
As used herein, “substantially inclined”, “substantially vertical” or words of similar effect shall mean sloped at a steep incline to an essentially vertical orientation. The greater the incline, the more difficulty bed bugs have climbing upwardly. Most surfaces, including glass, can allow bed bugs and similar pests to climb upwardly on an angle of a few degrees. However, depending on the life stage of the bug and the smoothness of the surface, increasing the angle of the incline will eventually make it impossible for the pest to traverse to the top of the surface.
As used herein, “guide surface” or words of similar effect shall mean a substantially smooth surface fabricated as part of a larger trap or as a separate element placed in the a bed bug's or similar pest's environment. The smoothness of the guide surface substantially impedes bugs from crossing the surface and causes them to stay on their preferred textured climbing surface, thus following the edge of the guide surface. Such guide surfaces can be used as a means of guiding the bugs toward a trap location or a treatment location. Guide surfaces may include, without limitation, tape or strips of plastic having a smooth exterior surface which may be attached to substrates such as walls, furniture, bed legs, and bed frames to both protect a bed and guide the bugs to a trap or treatment zone.
As used herein, “transition line” or words of similar effect shall mean the edge of a guide surface or similar smooth surface. The transition line is the border between a textured surface that bed bugs or similar pests can comfortably and freely move on and a smooth surface that impedes their movement. The transition line guides the bugs to move alongside the guide surface as they traverse a textured surface.
As used herein, “intercept wall” or words of similar effect shall mean a substantially smooth wall or barrier placed substantially perpendicular to the path of movement of a bed bug or similar pest. An intercept wall at least partially impedes the bug's motion and operates as a means of increasing the likelihood of the bug's interaction with a trap or treatment zone. An intercept wall is ideally placed along the transition line of a guide surface so that bugs are intercepted as they follow the textured surface and are impeded from continuing further along the transition line. Once the bugs contact the intercept wall, they are redirected along the wall to contact a trap, treatment zone, or other type of control or monitoring device.
As used herein, “trap”, “trapping means” or words of similar effect shall mean a device or other means located adjacent to or connected to an intercept wall by which bed bugs or similar pests are trapped as they navigate around the intercept wall. The trapping means can be glue, a pitfall, or other means of immobilizing or capturing the bugs.
As used herein, “treatment zone”, “treatment means” or words of similar effect shall mean a pesticide treated space located adjacent to or connected to an intercept wall and over which the bed bugs or similar pests pass whereby the bugs are exposed to the pesticide as they navigate around the intercept wall. The treatment zone combined with the intercept wall provides a means of applying very small amounts of pesticides while treating pests harvested from a much larger foraging area. Once bugs are exposed to the pesticide they either die or carry the residual pesticide back to other bugs at their harborages.
As used herein, “pest control means”, “bed bug control means” or words of similar effect shall mean a trapping means and/or a treatment means.
With the foregoing in mind, referring to the drawings wherein like or similar references indicate like or similar elements throughout the several views, there is shown in
As depicted in
According to the embodiment of the invention shown in
Alternatively, while described above as being the exposed or outer surface of flexible adhesive tape, it will be understood that guide surface 18 may be the smooth outer surface of a strip of plastic or even glass that may be affixed, either fixedly or releasably, to substrate 14 by any suitable means such as epoxy adhesive, tack adhesive or mechanical fasteners such as screws, nails or the like (either with or without additional anchor means).
Preferably, intercept wall 20 extends substantially perpendicular to the plane of the substrate on which the bug is travelling which, in the present example, is a substantially vertical wall, bed platform or furniture surface 14. In the present case, while substantially orthogonal or perpendicular to surface 14, intercept wall 20 also preferably extends substantially vertically. Following the bottom edge 26 of tape 24, the bug eventually meets with the intercept wall 20, which itself is preferably a substantially smooth surface whereby the bug's motion is impeded. Upon encountering the intercept wall, therefore, the bug is redirected toward a pest treatment zone and/or trap as described below.
As seen in
The receptacle 28 desirably includes a handle 38 and is removably connectable to bracket 36 via a shoulder or similar structure 40 upon which rests a lower surface 42 of an upper flange 44 of receptacle 28. In the embodiment of the invention shown in
As seen in
According to a preferred embodiment, the transition zone is constructed as at least one convex surface 46 extending between at least the open top 30 to the side walls 34, and possibly to the closed bottom 32. At least the innermost/lowermost portions of the convex surface are desirably substantially smooth in order to increase the likelihood that the bug eventually loses traction and falls into the pitfall. Likewise, the side walls 34 are desirably substantially vertical and their inner surfaces are preferably substantially smooth in order to assure that the trapped bug cannot escape the pitfall once it has fallen into it.

In contrast to the embodiments of the invention thus far disclosed, the system represented in
As seen in
In addition to or in lieu of a pitfall, the trapping means according to the present invention can be glue located adjacent suitable intercept wall(s). The glue may be provided on either the substrate or a structural component of the pest control means such as a member that is permanently or removably attached to the substrate adjacent the intercept wall(s).
It is further contemplated that the pest control means of the invention may include a pest treatment zone, which zone may be a dedicated element permanently or removably connected to a pest control means support structure such as a bracket in the manner described above. By way of example but not limitation, the treatment zone may comprise the upper surface of upper flange 44 of receptacle 28. As noted above, the treatment zone is preferably coated with a liquid or powder pesticide that may kill pests upon contact or may have a delayed reaction whereby the pests may carry residual pesticide to their nests whereby additional pests may become poisoned and eventually die because of their interaction with the treated pests. In this way, much less pesticide may be used than in conventional pesticide treatment applications. Consequently, the cost of treatment is reduced while treatment safety is improved.
Although the invention has been described in detail for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention as claimed herein.
