- This application is a continuation of U.S. application Ser. No. 15/949,503, filed on Apr. 10, 2018, which is a continuation of U.S. application Ser. No. 15/196,809, filed on Jun. 29, 2016, now U.S. Pat. No. 9,961,891, which: (1) is a continuation-in-part of U.S. application Ser. No. 13/971,202, filed on Aug. 20, 2013, (2) is a continuation-in-part of U.S. application Ser. No. 14/573,110, filed on Dec. 17, 2014, now U.S. Pat. No. 9,504,241, issued on Nov. 29, 2016, which claims the benefit of U.S. Provisional Application No. 61/918,028, filed on Dec. 19, 2013, and (3) claims the benefit of U.S. Provisional Application No. 62/208,983, filed on Aug. 24, 2015. The entire teachings of the above applications are incorporated herein by reference.
- Fruit flies contaminate food, wreak havoc on the liquor stores of bars and restaurants, and destroy crops; costing money in wasted product and lost produce. Conventional methods for attempting to remove these pests often employ toxic chemicals and physical traps, such as, for example, dangling adhesive tapes. While these methods may successfully remove some flies from a local environment, they also have downsides. In a business environment, especially for a food service, a dangling tape of dead flies is neither sanitary nor something that should be observed by the clientele. In the case of chemical traps, toxic chemicals pose health risks if not handled or disposed properly.
- Disclosed herein are traps for flies (e.g., fruit flies) that do not require the use of toxic chemicals and are capable of being packaged in such a way that they can be present in public areas without being unsightly or intrusive. Unlike traditional traps and tapes, the disclosed traps isolate the captured flies in a container, separating them from the outside environment, and unlike traditional trap systems, which generally must be disposed and replaced, the disclosed traps are reusable, easy to set up, easy to clean, and easy to operate.
- One example fly trap includes a lower trap portion configured to contain a solution, an upper trap portion containing ambient air and that includes at least one opening to allow for ingress of flies, a conduit extending from the lower trap portion to the upper trap portion, a pump configured to be submersed in the solution and coupled to the conduit, and a timer for intermittently activating the pump. When activated, the pump causes solution to travel up the conduit and to flow along the inner surface of the upper trap portion. Any flies that have landed on the inner surface of the upper trap portion are captured by the flowing solution.
- Another example fly trap includes a housing configured to contain a solution and including at least one opening to allow for ingress of flies, a conduit arranged substantially vertically in the housing, a pump configured to be submersed in the solution and coupled to the conduit, and a timer for intermittently activating the pump. When activated, the pump causes the solution to travel up the conduit and to flow along the inner surface of the housing, capturing any flies that have landed on the inner surface.
- Another example fly trap includes a housing configured to contain a solution and including at least one opening to allow for ingress of flies, a nozzle located inside the housing and configured to spray the solution toward the top of the trap, a pump configured to be submersed in the solution and coupled to the nozzle, and a timer for intermittently activating the pump. When activated, the pump causes the solution to spray from the nozzle toward the top of the trap and to flow along the inner surface of housing, capturing any flies that have landed on the inner surface.
- Some of the above example traps may also include shield(s) coupled to the inner side of the opening(s) to prevent the solution from exiting the trap. The trap may also include a tray to be suspended above the solution for retaining fly bait, or may include a screen to be submersed in the solution and above the pump for retaining captured flies above the screen. The upper and lower trap portions may be separate pieces that can be coupled together, or can be part of one component. The opening may be created by a space between the upper and lower trap portions. The timer may be internal or external to the trap.
- Another example embodiment of the present invention is a fly trap that includes a gathering vessel, fluid trap, conduit, vacuum, and timing device. The gathering vessel includes a container to hold fly-attracting bait. The gathering vessel also includes a first opening allowing the flies to enter the gathering vessel and a second opening allowing for collection of the flies. The fluid trap is able to be partially filled with fluid. The conduit has a first end coupled to the second opening of the gathering vessel and a second end to be submerged within fluid inside the fluid trap. The vacuum is coupled to the fluid trap and removes air from the fluid trap to cause air and flies to flow from the gathering vessel, through the conduit, and into fluid inside the fluid trap. The timing device is electronically coupled to the vacuum and periodically activates and deactivates the vacuum.
- In some embodiments, the container is suspended inside the gathering vessel, and the gathering vessel may include a platform near the container for the flies to land. The interior of the gathering vessel can include a low-friction surface (e.g., coated with polytetrafluoroethylene) to reduce the flies' ability to stay in the gathering vessel when the vacuum is activated. In many embodiments, the timing device is configured to activate the vacuum for a first amount of time and deactivate the vacuum for a second amount of time, where the second amount of time is longer than the first amount of time. The vacuum may also include baffles to reduce noise emitted from the vacuum
- Another example embodiment of the present invention is a fly trap that includes a housing, gathering vessel, fluid trap, conduit, vacuum, and timing device. The gathering vessel is coupled to the housing and includes a container to hold fly-attracting bait. The gathering vessel also includes a first opening allowing the flies to enter the gathering vessel and a second opening allowing for collection of the flies. The fluid trap is located inside the housing and is able to be partially filled with fluid. The conduit has a first end coupled to the second opening of the gathering vessel and a second end to be submerged within fluid inside the fluid trap. The vacuum is located inside the housing, is coupled to the fluid trap, and removes air from the fluid trap to cause air and flies to flow from the gathering vessel, through the conduit, and into fluid inside the fluid trap. The timing device is located inside the housing, is electronically coupled to the vacuum, and periodically activates and deactivates the vacuum.
- In some embodiments, the gathering vessel is attached to the outside of the housing, and in others, the gathering vessel is located inside the housing, where the first opening of the gathering vessel is an opening in the housing. In many embodiments, the fluid trap is able to be removed from the housing.
- Another example embodiment of the present invention is a fly trap that includes a central fluid trap, multiple gathering vessels, multiple conduits, a vacuum, and a timing device. The central fluid trap is able to be partially filled with fluid. The multiple gathering vessels each include a container to hold fly-attracting bait, a first opening allowing the flies to enter the gathering vessel, and a second opening allowing for collection of the flies. The multiple conduits each have a first end coupled to the second opening of a corresponding gathering vessel, and a second end coupled to a common conduit to be submerged within fluid inside the central fluid trap. The vacuum is coupled to the fluid trap and removes air from the fluid trap to cause air and flies to flow from the gathering vessels, through the conduits, and into fluid inside the central fluid trap. The timing device is electronically coupled to the vacuum and periodically activates and deactivates the vacuum.
- In many embodiments, the multiple gathering vessels are located at locations remote from the central fluid trap. In some embodiments, a hub may be used to couple the multiple conduits to the common conduit, and the hub can include a switch that activates and deactivates various conduits. The switch may also cycle through the multiple conduits, activating a subset of the conduits at a given time.
- Another example embodiment of the present invention is a fly trap that includes multiple gathering vessels, multiple fluid traps, multiple collection conduits, a central vacuum, and a timing device. The multiple gathering vessels each include a container for fly-attracting bait, a first opening allowing the flies to enter the gathering vessel, and a second opening allowing for collection of the flies. The multiple fluid traps each are able to be partially filled with fluid. The multiple collection conduits each have a first end coupled to the second opening of a corresponding gathering vessel, and a second end to be submerged within fluid inside a corresponding fluid trap. The central vacuum is coupled to the fluid traps and removes air from the fluid traps to cause air and flies to flow from the gathering vessels, through the collection conduits, and into fluid inside the fluid traps. The timing device is electronically coupled to the vacuum and periodically activates and deactivates the vacuum.
- In many embodiments, the multiple gathering vessels and fluid traps are located at locations remote from the central vacuum. In some embodiments, a hub may be used to couple the multiple fluid traps to the central vacuum, where the hub is coupled to the multiple fluid traps by multiple vacuum conduits, and is coupled to the vacuum by a common conduit. The hub can include a switch that activates and deactivates various conduits, and that can cycle through the multiple vacuum conduits, activating a subset of the vacuum conduits at a given time.
- Another example fly trap includes an outer wall containing a solution, an inner wall extending into the solution, and a space formed between the outer wall and the inner wall. The trap also includes an air pump and one or more air supply conduits that supply air from the air pump to the solution. The air forms bubbles in the solution that rise in the space formed between the outer wall and the inner wall and that cascade downward within the inner wall and into the solution.
- Some example traps may also include one or more air stones to aide in forming the bubbles. The air stones are coupled to the ends of the one or more air supply conduits and are located within the solution. Other example traps may include a plate with multiple holes to aide in forming the bubbles. The plate is located within the solution and above the ends of the one or more air supply conduits, and can include a hole through which the lower end of the inner wall can extend to allow captured flies to be deposited in the solution. Other example traps may include an air passage with multiple holes to aide in forming the bubbles. The air passage is coupled to an end of the one or more air supply conduits and runs around the perimeter of the outer wall in the space formed between the outer wall and the inner wall.
- Some example traps can include a screen located in the solution above the lower end of the inner wall and below the ends of the one or more air supply conduits. The screen retains captured flies below the screen, and can include a hole through which the lower end of the inner wall extends to allow the captured flies to be deposited below the screen. Other example traps can include a mesh layer located at the bottom of the solution that can retain any captured flies.
- In many embodiments, the outer wall extends above the inner wall and is angled toward the inner wall to direct bubbles rising in the space formed between the outer wall and the inner wall toward the inner wall. Further, many embodiments can include outer and inner walls that are cylindrically shaped, but the fly traps contemplated herein are not limited to such a shape.
- Another example fly trap includes a container with a solution therein, a wall at one end of the container, and an angled surface located within the container and extending into the solution. A space is formed between the wall and the angled surface. The example fly trap also includes an air pump and one or more air supply conduits that supply air from the air pump to the solution. The air forms bubbles in the solution that rise in the space formed between the wall and the angled surface and that cascade downward along the angled surface and into the solution.

FIG. 16 is a schematic drawing of a fly trap, according to an example embodiment of the present invention. - A description of example embodiments of the invention follows.
- According to the embodiments illustrated in
FIGS. 1-6 , the body of a trap can create a collection vessel. A pump on an intermittent timer pumps bait fluid up a conduit (e.g., riser pipe) or through a nozzle where the fluid then hits the ceiling of the collection vessel, following the ceiling and edges, and runs back down into the reservoir created by the bottom of the collection vessel to be pumped through the conduit/nozzle again. The traps operate by intermittently projecting the fluid towards the top of the trap and down the trap's inside wall. Fruit flies present in the trap tend to instinctively land on the trap's inner wall surface when startled by the pump and projecting solution, only to be captured by the solution as it flows down the wall. When the pump is started, the fruit flies are rinsed off the wall into the reservoir, and any of the flies that take off when startled fly into the bait fluid covering the ceiling and walls and are washed into the reservoir. In addition, flies that are not on the inside of the trap's upper portion tend to fly up into the stream of fluid when startled by the pump. - The fruit flies can enter the trap through slot(s) in the side of the wall that may be shielded so the bait fluid does not exit the trap when flowing down the wall (as illustrated in
FIG. 3 ), or the upper trap body can have a smaller diameter than the lower trap body so the slot/opening can be created between the two pieces (as illustrated inFIG. 1 ). Slots should be above but close to the bait fluid level and located down from the top, which helps to prevent the fruit flies from finding an exit before being washed away. The low placement of the slot(s) works well because fruit flies tend to fly up into the top of the trap when startled, so such a slot placement provides nowhere for the flies to go but into the streaming bait fluid as it covers the ceiling and walls of the trap. However, the slots could be placed farther up the side of the trap in some embodiments without departing from the scope of the present invention. -
FIG. 1 shows an example of atrap 100. Theexample trap 100 includes alower trap portion 105 containing asolution 140 and anupper trap portion 110 containing ambient air and including at least oneopening 115 to allow for ingress of flies. Aconduit 120 extends from thelower trap portion 105 to theupper trap portion 110. Apump 125 is submersed in thesolution 140 and coupled to theconduit 120. Atimer 130 is configured to intermittently activate thepump 125. When activated, thepump 125 causes thesolution 140 to travel up theconduit 120 and to flow along the inner surface of theupper trap portion 110. Any flies that are on the inner surface of theupper trap portion 110 are captured by the flowing solution. Anoptional bait tray 135 can be included. Additional bait can be placed on thetray 135 and used to supplement the bait solution, or can be used instead of bait solution, in which case, plain water, for example, can be used as the solution. -
FIG. 2 shows another example of atrap 200. The trap is similar to that ofFIG. 1 , but includes anozzle 220 for spraying the solution from the lower portion of the trap toward to the upper portion, instead of a conduit. Theexample trap 200 includes alower trap portion 205 containing asolution 240 and anupper trap portion 210 containing ambient air and including at least oneopening 215 to allow for ingress of flies. Apump 225 is submersed in thesolution 240 and coupled to anozzle 220 to spray the solution from the lower portion of the trap toward to the upper portion. Atimer 230 is configured to intermittently activate thepump 225. When activated, thepump 225 causes thesolution 240 to spray from thenozzle 220 and to flow along the inner surface of theupper trap portion 210. Any flies that are on the inner surface of theupper trap portion 210 are captured by the flowing solution. Anoptional bait tray 235 can be included. Additional bait can be placed on thetray 235 and used to supplement the bait solution, or can be used instead of bait solution, in which case, plain water, for example, can be used as the solution. Thenozzle 220 ifFIG. 2 is shown as having a particular shape, but can take many forms without departing from the scope of the present invention -
FIG. 3 shows another example of atrap 300. Thetrap 300 is similar to that ofFIG. 1 , but the opening(s) for flies to enter thetrap 300 is provided byslots 315 a,b in the wall of theupper trap portion 310. Theexample trap 300 includes alower trap portion 305 containing asolution 340 and anupper trap portion 310 containing ambient air and including at least one opening 315 a,b to allow for ingress of flies. Aconduit 320 extends from thelower trap portion 305 to theupper trap portion 310. Apump 325 is submersed in thesolution 340 and coupled to theconduit 320. Atimer 330 is configured to intermittently activate thepump 325. When activated, thepump 325 causes thesolution 340 to travel up theconduit 320 and to flow along the inner surface of theupper trap portion 310. Any flies that are on the inner surface of theupper trap portion 310 are captured by the flowing solution.Shields 345 a,b may be coupled to the inner side of the opening(s) 315 a,b to prevent thesolution 340 from exiting the at least one opening 315 a,b. Anoptional bait tray 335 can be included. Additional bait can be placed on thetray 335 and used to supplement the bait solution, or can be used instead of bait solution, in which case, plain water, for example, can be used as the solution. Theupper trap portion 310 and thelower trap portion 305 can be separate pieces that can be coupled together (e.g., at line 350), or can be part of one component. -
FIG. 4 is a perspective drawing of a fly trap similar to that ofFIG. 1 , according to an example embodiment of the present invention.FIG. 4 is a front elevation view showing anupper trap portion 110, lower trap portion, oneopening 115 to allow for ingress of flies, andconduit 120 extending from thelower trap portion 105 to theupper trap portion 110. -
FIG. 5 is a top view drawing of the fly trap ofFIG. 4 .FIG. 5 shows theupper trap portion 110, lower trap portion,conduit 120, and pump 125. -
FIG. 6 is a cross sectional drawing of the fly trap ofFIG. 4 .FIG. 6 shows example dimensions of the trap according to one example embodiment. - According to the embodiments illustrated in
FIGS. 7-11 , the fly traps in their various configurations employ a two-step process to remove unwanted flies from the local environment. The first step is a lure using, for example, a household and non-toxic attractant, such as apple cider vinegar, attracting flies in the local environment to the trap. The second step is an intermittent suction effect used to physically pull the flies from the area around the lure into the trap vessel, completing the removal of pests from the area. The fly trap uses a collection of devices, including a physical trap, a vacuum, and an electronic intermittent timer. -
FIG. 7 is a schematic drawing of a fly trap, according to an example embodiment of the present invention. On the left side ofFIG. 7 , a physical trap is shown. At the top of the trap is a gatheringvessel 705 in the shape of a cylindrical funnel, which contains a lure in acontainer 715. The gatheringvessel 705 has a first opening (e.g., wide-mouth) 720 facing upwards with asmall container 715 suspended within, holding the fly attractant. Trusses that support the suspendedlure container 715 may also function as surface area for flies to land on around the lure. In the particular embodiment shown, a second opening (e.g., lower tip) 725 of the gatheringvessel 705 is inserted into the top of afluid trap 710 and connects to the top 735 of a conduit (e.g., tube) 730 running down most of the height of the chamber of thefluid trap 710. Water, for example, may be used inside the body of thefluid trap 710 to fill the bottom, submerging theoutput 740 of the conduit (intake tube) 730 under water. When the vacuum is active theintake tube 730 leads flies from the gatheringvessel 705 into the body of thefluid trap 710, the force of which disables and submerges the flies in thefluid trap 710. At the top of the trap, for example, is another tube, leading from inside the chamber of thefluid trap 710 to the outside. This tube connects to avacuum system 745 that creates negative pressure inside the body of thefluid trap 710, pulling flies from the gatheringvessel 705 into the water below. One aspect of the trap's effectiveness is anintermittent timer 750 that controls when thevacuum 745 is active. Activation of the suction on an interval accomplishes several things. Operation is automatic and requires no supervision. The trap is more effective when run on an interval because flies are allowed to collect near the lure without being disturbed, then the vacuum is activated and the trap is active for a short amount of time. Success has been achieved with a 15-minute off/1-minute on interval, for example. The system also saves power because the vacuum is only in operation for one minute, four times an hour, for example; thus, the impact on power cost is minimal. - An example embodiment of the device may function as follows. The interior of the
fluid trap 710 can be filled with approximately two inches of water, submerging theoutput side 740 of theintake tube 730. A drop of dish soap may be added to the water to reduce surface tension of the water and ensure flies are quickly saturated when pulled into the water. The bubbles also help dispatch the flies. The lure of the gatheringvessel 705 may be prepared by adding a non-toxic natural attractant, such as vinegar or fruit juice, to thecontainer 715. Thevacuum 745 can be attached to an output tube at the top of thefluid trap 710, and be connected to anelectronic timer 750, which controls automatic operation of thevacuum 745. The device is placed in an area where flies have become a problem, plugged in (or operated by battery), and left to operate for a time (e.g., overnight), trapping the pests and cleaning the environment. A user may then simply remove a lid of thefluid trap 710, empty thefluid trap 710 into a sink or toilet, and the trap is ready to be cleaned and refilled for re-use, if needed. -
FIG. 8 is a schematic drawing of a fly trap contained within ahousing 810, according to an example embodiment of the present invention. As a manufactured product, the device could be packaged in a self-containedunit 805, as shown inFIG. 8 . InFIG. 8 , the gatheringvessel 705,fluid trap 710,vacuum 745,timing device 750, and related components are all contained within ahousing 810. While the gatheringvessel 705 is shown as being located inside thehousing 810, with thefirst opening 720 of the gatheringvessel 705 being an opening in thehousing 810, the gatheringvessel 705 can alternatively be attached to the outside of thehousing 810, similar to the gathering vessel ofFIG. 7 . The overall functionality of the trap remains the same, but such a purpose-built version of the trap would allow the device to be employed even during business hours, in public areas. Using avacuum 745 that is properly scaled in power and quieted with baffles, the device could come in multiple versions appropriate for different environments. A low-power version could be used for home or in social businesses, such as a bar, small restaurants, and grocery stores. In such areas a primary concern would be non-intrusive operation. A higher-power version could be available for commercial kitchens, health-care facilities, breweries, distilleries, and fruit growing and processing locales, where sound or power usage is less of a concern and airborne pests may be more numerous. -
FIG. 9 is a schematic drawing of a fly trap with multiple gathering vessels 905 a-d, according to an example embodiment of the present invention. A modular system can be employed, with acentral vacuum 745 being attached to multiple gathering vessels 905 a-d. This could be used at a bar, for example, with the trap out of view (e.g., behind the bar), and small gathering vessels placed near sinks or garnish trays. This configuration could also be used on a much larger scale, such as in an orchard. In such a configuration, the trap includes acentral fluid trap 710, multiple gathering vessels 905 a-d, multiple conduits 930 a-d, acentral vacuum 745, and atiming device 750. The multiple conduits 930 a-d each have a first end 920 a-d coupled to a corresponding gathering vessel 905 a-d, and a second end 925 a-d coupled to acommon conduit 915 to be submerged within fluid inside thecentral fluid trap 710. As shown inFIG. 9 , ahub 910 may be used to couple the multiple conduits 930 a-d to thecommon conduit 915. Thehub 910 may also include a switch (not shown) that activates and deactivates various conduits, and that can cycle through the multiple conduits, activating a subset of the conduits at a given time and allowing the device to use a lower-power vacuum but still handle multiple trap locations. -
FIG. 10 is a schematic drawing of a fly trap with multiple gathering vessels 1005 a-d and fluid traps 1010 a-d, according to an example embodiment of the present invention. A modular system can be employed, with acentral vacuum 745 being attached to multiple gathering vessels 1005 a-d and multiple fluid traps 1010 a-d. In such a configuration, the trap includes multiple gathering vessels 1005 a-d, multiple fluid traps 1010 a-d, multiple conduits 1015 a-d, acentral vacuum 745, and atiming device 750. The multiple conduits 1015 a-d each have a first end 1025 a-d coupled to a corresponding gathering vessel 1005 a-d, and a second end 1030 a-d to be submerged within fluid inside a corresponding fluid trap 1010 a-d. Each of the fluid traps 1010 a-d is coupled to thevacuum 745 of the system by a corresponding vacuum conduit 1020 a-d. -
FIG. 11 is a schematic drawing of a fly trap with multiple gathering vessels 1105 a-d and fluid traps 1110 a-d, according to an example embodiment of the present invention. The trap system ofFIG. 11 is similar to the system ofFIG. 10 , except that the vacuum conduits 1120 a-d are coupled to thevacuum 745 using ahub 1140 andcommon conduit 1135. Thehub 1140 of the particular embodiment also includes a switch that activates and deactivates various vacuum conduits 1120 a-d. The switch may also cycle through the multiple vacuum conduits 1120 a-d, activating a subset of the vacuum conduits 1120 a-d at any one time, allowing the system to use a lower-power vacuum 745 but still handle multiple trap locations. - According to the embodiments illustrated in
FIGS. 12-16 , fly traps can operate by creating a cascading wall of bubbles that flies (e.g., fruit flies) appear to view as a solid surface, and when the flies attempt to land on the cascading wall of bubbles, the bubbles pop and secure the flies. The wall of bubbles continues to slide down into the trap (e.g., down aslanted wall 1215 of aflat trap 1200 as shown inFIG. 12 , or down the inside 1310 of a round (or rectangular, or other enclosed shaped)trap 1300 as shown inFIG. 13 , for example) until the secured flies and remaining bubbles reach the bait/bubble solution. The bait/bubble solution continually circulates creating a moving body of bubbles (e.g., like a conveyer belt, for example), which returns back to the original location and becomes liquid again to make more bubbles. As flies land on the moving body of bubbles, the bubbles pop, entrapping the flies in the moving body of bubbles, which continues back to the bubble/bait reservoir where the flies drown and are collected until the trap is rinsed. -
FIG. 12 shows an example of a “flat trap” 1200. In the flat trap example, the bubbles are created between a bubble slide (slanted/angled surface) 1215 and aback wall 1205 and rise in the space between thebubble slide 1215 and theback wall 1205. At the top, a lip of theback wall 1205 directs the bubbles over theslide 1215, which then cascade down theslide 1215, where at the bottom of the slide the bubbles pop and join the rest of the bubble/bait solution to continue the cycle. The bubbles are created using an air pump (not shown) and hose/conduit to transfer the air and an air diffuser, such as an air stone, 1220. -
FIG. 13 shows an example of a “round trap” 1300. In the round trap example, the bubbles are created and rise between anouter wall 1305 andinner wall 1310. The bubbles follow the space between theouter wall 1305 andinner wall 1310 to the top, where a bent lip of theouter wall 1305 directs the bubbles into the center, where the bubbles cascade down within theinner wall 1310, where at the bottom, the bubbles join the rest of the bubble/bait solution in asolution return 1315. Theexample trap 1300 also includes anair pump 1320, one or moreair supply conduits 1325 a,b, andair stones 1330 a,b. Theexample trap 1300 also includes ascreen 1335 to retain any captured flies below thescreen 1335. Thescreen 1335 includes a hole in its center through which theinner wall 1310 extends to create thesolution return 1315.FIG. 14 shows the “round trap” ofFIG. 13 from a top view. - In both the flat and round examples, as the flies land on the cascading wall of bubbles, the bubbles pop, entrapping the flies in the cascading bubble wall, which continues back to the bubble/bait reservoir, where the fruit flies drown and are collected until the trap is rinsed. The example traps may include three components: a bait/bubble solution, an air pump scaled to the size of the trap and connected to an air stone or other device for bubble formation, and a collection area. Use of an air stone, in one example, creates many small bubbles that are directed in a manner that creates a wall of bubbles available for the flies to land on, which returns to the collection area depositing the flies. The air pump may be scaled to the size of the trap in order to provide a sufficient volume of air to the air stones or bubble hoses for proper bubble formation. The bait/bubble solution may contain an attractant to draw flies to the trap. Additional ingredients may be added to the bubble bait solution to create bubbles that last long enough to create the bubble wall but then will pop easily when the flies land on the bubbles and when the bubbles rejoin the remaining solution. One example solution may include water, apple cider vinegar, and a drop of dish soap.
- The flat trap example can be made in specific sizes or can be manufactured in a modular/cut-to-fit manner enabling an installer to install a trap along the whole length of a wall, for example, in locations with large fruit fly problems. The flat trap example can also include a drain valve, allowing easy cleaning if mounted on a wall. The round trap example can fit nicely among liquor bottles on a shelf of a bar or restaurant, or on a countertop in a residence. The round trap example may be made in two parts, such that the inner structure slides out for easy cleaning. Both design examples can incorporate light as an attractant by making the outer walls opaque, and the bubble slide and/or inner walls translucent, and adding a light source. This illuminates the bubble wall to add to its attractant nature. Both design examples can include additional features designed to aid in popping the bubbles where the cascading bubble wall joins the rest of the solution. Such additional features may include additional structures, moving parts, or spraying water.

Theexample trap 1600 includes anouter wall 1605 containing a solution, aninner wall 1610 extending into the solution, and a space formed between theouter wall 1605 and theinner wall 1610. Theexample trap 1600 also includes an air pump 1620 and anair supply conduit 1625 that supplies air from the air pump 1620 to the solution. As in the above examples, the air forms bubbles in the solution that rise in the space formed between theouter wall 1605 and theinner wall 1610 and that cascade downward within theinner wall 1605 and into the solution at the solution. Thetrap 1600 also includes a bubble ring (an air passage) 1630 having holes through which the air from theair supply conduit 1625 exits thebubble ring 1630 and becomes multiple bubbles. Thebubble ring 1630 aides in the creation of multiple evenly distributed bubbles. Theexample trap 1600 also includes amesh layer 1615 that can retain any captured flies at the bottom of thetrap 1600. - While the invention has been particularly shown and described with references to example embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims. For example, traps can take different shapes than disclosed herein, but operate in a similar fashion as described above. Variations in bait solution can allow the trap to be effective on flying pests besides fruit flies, including mosquitos and bees, for example. Programmable timers may be used, allowing a user to customize the operating intervals to better suit particular needs. In embodiments using a gathering vessel, there may be many variations in the size and shape of the gathering vessel. For example, the width and depth of the vessel can vary, platforms can be added for flies to land on or near the bait, or multiple partitions may be used for multiple bait types. Various aerodynamic shapes of the funnel, lure container, and suspension trusses can increase effectiveness at a given power level. In embodiments using air supply conduits, one or two air supply conduits have been shown in the above examples, but any number of air supply conduits may be used.
