[0073] FIG. 1A is a top view of a first embodiment of a trap barrier. FIG. 1B is a cross-sectional view of the trap barrier of FIG. 1A along arrows 1B.

[0074] Referring to FIGS. 1A-1B, the trap barrier can include a solid base bottom 100 having a generally ring shaped pit or moat with a sticky surface 150 and an inner wall 110 for supporting a furniture leg inside of a well area 120 and having an outwardly bent edge 130 with a lower facing surface having a smooth surface or pesticide treated surface.

[0075] The barrier can have an outer wall 102 having an inwardly bent edge 106, with an undersurface 107 that can have a smooth(slick) or pesticide-treated surface. Additionally, the undersurface can be both a smooth(slick) surface with a pesticide treated surface.

[0076] The inner wall 110 can have a greater height than the outer wall 102. Underneath the base bottom 100 can be a surface 160 such as a slick surface to facilitate moving furniture that is supported by the barrier. Here, the outer wall 102 is generally perpendicular to the base 100.

[0077] Smooth surface 140, 107, can include but is not limited to any plastic material, such as but not limited to plastic laminated paper, polyurethane, polyacrylic, and Plexiglas.

[0078] Pesticide treated surfaces 140, 107 can include but are not limited to Pyrethroids (e.g. permethrin, cypermethrin, lambacyhalothrin, cyfluthrin), organophosphates (e.g. malathion, dichlorvos), carbamates (e.g. propoxur, methomyl), repellents (e.g. diethyl toluamide, piperazines), essential plant oils (e.g. lemongrass oil, thyme oil, citronella, geraniol).

Sticky surface 150, such as but not limited to sticky surface such as those used in a Victor roach glue trap and monitor (Woodstream Corporation, Lititz, Pa.).

[0079] Slick surface 160, can include but is not limited to plastic, glass, Teflon coated metal, polished metal, smooth painted or varnished surfaces.

[0080] FIG. 2A is a top view of a second embodiment trap barrier. FIG. 2B is a cross-sectional view of the trap barrier of FIG. 2A along arrows 2B.

[0081] The embodiment in FIGS. 2A-2B is similar to that in the previous embodiment, with the exception of having the outer wall 104 angled inwardly from the base portion 100.

[0082] FIG. 3A is a top view of a third embodiment trap barrier. FIG. 3B is a cross-sectional view of the trap barrier of FIG. 3A along arrows 3B. FIG. 3C is a bottom view of the trap barrier of FIG. 3A.

[0083] A base portion 300 can form a protector top having a furniture attachment peg extending upward from a mid portion of the base for insertion into a bottom of a furniture leg. Extending below the base can be a downwardly protruding outer side wall 310 forming a channel therein with a furniture support leg 350 extending downwardly from a mid portion of the base. A channel can include a lower facing surface 340 having one of the smooth surface or the pesticide treated surface. The furniture support leg 350 is large enough to raise the outer side wall 310 above the floor support surface.

[0084] FIG. 4A is a top view of a fourth embodiment trap barrier. FIG. 4B is a cross-sectional view of the trap barrier of FIG. 4A along arrows 4B. FIG. 4C is a bottom view of the trap barrier of FIG. 4A.

[0085] FIGS. 4A-4C are similar to the embodiment of FIGS. 3A-3C with the exception of substituting a caster wheel 360 for the furniture support leg 350.

[0086] FIG. 5A is a top view of a fifth embodiment trap barrier. FIG. 5B is a cross-sectional view of the trap barrier of FIG. 5A along arrows 5B. FIG. 5C is a bottom view of the trap barrier of FIG. 5A.

[0087] FIGS. 5A-5C are similar to FIGS. 3A-4C with the exception of removing the peg and both the lower facing furniture leg or caster wheel, and instead having a through-hole 220 through the mid-portion of the base for allowing the barrier to be attached to a bottom of a furniture leg by a fastener, such as a screw of bolt.

[0088] FIG. 6 is a side cross-sectional view of the first embodiment trap barrier 400 shown and described above in reference with FIGS. 1A-1B used with a small furniture leg 500 which supports a piece of furniture 600 in the wheel well of barrier.

[0089] FIG. 7 is a side cross-sectional view of the first embodiment trap barrier 400 shown and described above in reference to FIGS. 1A-1B, used with a large furniture leg 500 underneath a piece of furniture 600 supported by the outwardly protruding upper edges of the inner wall.

[0090] FIG. 8 is a side cross-sectional view of the first embodiment trap barrier 400 shown and described in FIGS. 1A-1B, with the piece of furniture 600

[0091] directly supporting the piece of furniture on the outwardly protruding edges of the inner wall.

[0092] FIG. 9 is a table of bedbugs trapped in the top of the trap, within the trap and outside of the trap. FIG. 10 is a graph of the percentage of bed bugs trapped in the top of the trap, within the trap and outside of the trap.

[0093] Referring to FIGS. 9-10, the test data shows that bedbugs entering the top of the trap can only stay on the top or be trapped within the trap. Once bed bugs are within the trap they cannot escape either going to the top or to the outside of the trap. Bed bugs that are outside of the trap can only stay outside or be trapped within the trap.

[0094] The test data provides support for showing bed bugs on the ground cannot climb into the furniture being protected by the trap. Bed bugs already on the furniture can be trapped in the trap if they try to move away from the furniture.

[0095] Tests were done using a barrier trap according to the invention. 80 bed bugs were released either on top of the trap (where the furniture leg would be surrounded by the trap), within the trap (the pitfall part of the trap that captures bed bugs), and outside the trap (simulating bed bugs in the room from crawling onto the furniture). The only smooth surfaces of the trap were horizontal to the floor; all other traps have basically a vertical smooth or talc covered smooth surface. Bed bugs were left overnight.

[0096] During the test, no bed bugs in the pitfall part of the trap escaped. As such, the pitfall part of the trap has been shown to be 100% effective in preventing bed bugs from moving out of the pitfall area of the trap.

[0097] All bed bugs that left the top part of the trap were captured in the pitfall part of the trap. So it was 100% effective in capturing bed bugs that left the top of the trap (furniture contact area). Just a few remained on top of the trap at the end of the assay. A total of 92.5% of bed bugs were captured in this assay.

[0098] All bed bugs that moved from the perimeter area and crawled into the trap were captured. So the trap was 100% effective in protecting the legs of furniture from movement of bed bug released near the trap. There was no attractant on top of the trap and most bed bugs settled down in the area around the trap. So 27.5% of bed bugs were captured.

[0099] FIG. 11 shows a top view of the UF (University of Florida) urban entomology trap used for testing. The trap corresponds to FIGS. 1A and 1B described above.

[0100] The UF trap was prepared by adding 2 ml of Mountain Dew then drying the trap with a blow dryer on high heat for approximately 10 minutes. The excess fluid was then poured out and the trap remained unaltered for approximately 24 hours before introducing 8 bed bugs.

[0101] FIG. 12 shows a top view of a commercial climb up trap used for testing.

[0102] The Climb up Insect Interceptor is described and shown in U.S. Pat. No. 9,066,511 to McKnight et al. and includes plural pitfall traps to intercept crawling arthropods and insects.

[0103] The Climbup traps were prepared using 2 ml of Mountain Dew. The Mountain Dew was dried using the high heat and cool air settings on a blow dryer for approximately 10 minutes. The excess fluid was then poured out and the trap was untouched for approximately 24 hours before introducing 8 bed bugs.

[0104] Testing of 7 Climbup Intereceptors and 7 University of Florida Urban Entomology prototypes was done at the University of Florida, Urban Entomology Lab from spring to summer 2015.

In addition to the traps referenced above, the following materials were used with the traps during the experiments. [0105] Roughly 1 tbsp Guacamole [0106] A small hand full of Lays Original Potato Chips [0107] 2 tbsp Kraft Mac-n-Cheese singles cup, prepared following package instructions [0108] Contents of a vacuum post use on a carpet in a house with animals (dogs and cats) where the owner uses carpet cleaner and pet odor eliminators [0109] 2 ml Original Hidden Valley Ranch salad dressing [0110] 120 adult Bed Bugs, KVS strain

[0111] During testing, food materials such as Guacamole, Potato Chips, Mac-n-Cheese, and salad dressing were dropped into both types of traps (the invention traps and the commercial traps) to simulate what could normally occur during normal use of the traps during human habitation conditions.

[0112] The open commercial climb up trap (FIG. 12) can become compromised where the food materials provide a walking surface for the travelling bed bugs to escape the trap and/or climb the furniture.

[0113] The dropped food materials on the UF trap (FIG. 11) does not compromise the purpose of the trap, because the slick and/or pesticide treated undersurfaces are not affected by the dropped food materials. As such normal habitation will not detrimentally affect the novel UF traps shown in FIG. 11 and other Figures in the subject application.

[0114] FIG. 13 is a graph showing the percentage of bed bug traps failed after 7 days. After 7 days of use, the UF traps had an approximately 13 to 14% failure rate. The commercial traps had an over 55% failure rate after 7 days which is approximately 4 times (400 percent greater) failure rate than the UF traps.

[0115] FIG. 14 is a graph showing the percentage of escaped adult KVS bed bugs after 7 days. The UF traps had a low percentage of less than approximately 2% of the bed bugs escaping from those traps. The commercial traps had a significantly greater than approximately 12% of the trapped bed bugs escaping from the traps, which is approximately 6 times (600 percent greater) than the UF trap escape percentages.

[0116] FIG. 15A is a top view of a sixth embodiment trap barrier 700. FIG. 15B is a side cross-sectional view of the trap barrier 700 of FIG. 15A along arrows 15B. The trap barrier 700 is similar to the trap barrier shown and described in reference to FIGS. 1A-1B, the outer well 102 and inner edge 106 are removed so that no trap well (moat) exists. As such crawling arthropods and bed bugs can reach the underside surface 140, which can be a smooth or pesticide treated surface which prevents the crawling arthropods and bed bugs from reaching furniture legs supported by the trap barrier 700.

[0117] With the embodiments described, above, the upside down smooth or pesticide treated surfaces would not generally attract dirt, since these treated surfaces are elevated underneath pitfall barriers.

[0118] Although the embodiments describe having either a smooth or pesticide treated under surface areas, the invention can be practiced with an underside surface area portions having a combined smooth(slick) and pesticide surface for the upside down facing surfaces that do not touch a floor surface.

[0119] The invention can be used in other applications in addition to being underneath furniture. For example, the novel traps can be placed in various locations around a space, such as on a floor, stairs, a shelf, top of furniture, in commercial locations (hotels, motels and the like) as well as any residential locations (houses, condominiums, and the like). The novel invention can be used in other areas were bed bugs can occur, such as but not limited to recreational vehicles, truck cabins, inside vans and automobiles, and the like.

[0120] While the invention has been described, disclosed, illustrated and shown in various terms of certain embodiments or modifications which it has presumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
