Bedbug trap with carbon dioxide generator

Abstract

A bedbug trap that has a series of stacked containers. The top container holds a quantity of water, sugar and yeast, which generates carbon dioxide. The central container holds a small heating pad to attract the bedbugs and to heat the water and yeast mixture to aid in the fermentation. A hose with a water trap system brings the generated carbon dioxide from the upper chamber to the bottom chamber. This chamber sits in a bowl that has a rough exterior and a smooth interior. Holes, formed around the base of the bottom chamber allow the carbon dioxide to escape into the room, which attracts the bedbugs. The assembled unit is large, to trap as many bedbugs as possible in the shortest amount of time. Finally, the water, sugar and yeast are common household items that are easily and cheaply replenished as needed.

DETAILED DESCRIPTION OF THE INVENTION

(7) Referring now to the drawings and particularly, FIGS. 1 and 2, the bedbug trap 10 is shown. The trap 10 has a number of stacked and nested containers as shown in FIG. 1. FIG. 2 shows these containers in an exploded view. The uppermost container 11 is a large hollow vessel that has a removable top or lid 11a. As discussed below, the sugar, water and yeast mixture is held in this container. This container is placed into the middle container 12. Note the bottom 12a of the middle container 12 This container is also a hollow vessel. A heating pad 12b is stored in the bottom of this container as shown. Note the power cord 12c of the heating pad 12b and the switch 12d. The upper container 11 is designed to fit on the top of the heating pad 12b, which enables heat to heat the sugar, water and yeast mixture is held in upper container 11.

(8) As discussed above, the upper container 11 has a top 11a. This top is fit onto the top of the upper container as shown in FIG. 1. Note the insulation 15 placed around the upper container and the middle container. A tube 16 is used to carry the carbon dioxide (CO.sub.2), which is produced in the upper container, to the lower container 13. The hose 16 has an airlock attachment 17 attached as shown. The airlock 17 is filled with water. This causes the CO.sub.2 to pulse through the airlock. This pulsation simulates natural breathing. As shown, the hose 16 carries the CO.sub.2 to the bottom 12a of the middle container and it exits through the center of the bottom 12a as shown. In this way, the hose 16 injects the CO.sub.2 into the lower container 13. Note that the lower container 13 has a series of holes 13a formed in the lower portion of the lower container as shown. The CO.sub.2 from the upper container escapes into a room through these holes. As noted, the airlock provides pulsed supply of CO.sub.2 which, when combined with the heat generated by the heating pad 12b, attracts bedbugs. Note that the position of the heating pad also allows it to heat the lower container as well.

(9) At the base of the bedbug trap 10 is the holding container 14. As shown, the lower container 13 fits into the holding container. The outer surface of the lower container 14a has a rough surface (note the rough surface covers the entire outer surface of the container) that allows the bedbugs to climb into the holding container. The inside surface of the holding container should be smooth, ensuring that the bedbugs, once in the container 14 will be trapped. It is possible to add some powdered insecticide, such as diatomaceous earth, to kill the bedbugs quickly. In use, bedbugs are found in both the holding container 14 and in the lower container 13.

(10) After the device has been assembled, sugar/yeast/water mixture has been added and the heating pad is turned on, the operation of the device is automatic. Once the sugar/yeast/water mixture starts to release CO.sub.2 the bedbugs are attracted to it. Overtime, one simply has to replenish the sugar/yeast/water mixture and to clean out the holding and lower containers.

(11) FIG. 3 is a detail view of the middle container showing an insulation wrap 15 therefor. As noted above, and as shown in FIG. 1, the middle container 12 and a portion of the upper container are wrapped with insulation 15 to concentrate the heat from the heating pad and to present a heat signature towards the lower container, in concert with the emission of the CO.sub.2.

(12) FIG. 4 is a top perspective view of the preferred water trap for the bedbug trap system. As noted above, a brewing S-type airlock 17 is preferably used to pulse the CO.sub.2 from the upper container out to the lower container. Note that the water 100 trapped in the airlock also acts to contain any odor emitted from the upper container.

(13) FIG. 5 is a perspective view of an assembled bedbug trap showing an alternative water trap system. The device also works by making a loop 19 in hose 16 and adding a small amount of water 100, that is trapped in the loop 19. This allows the CO.sub.2 to escape and still provides a pulsating delivery of the gas. Although this alternative works, it is not preferred.

(14) FIG. 6 is a side exploded schematic view of the major elements of the bedbug trap showing assembly and operation of the trap. This figure does not show all of the elements used in the trap. However, it does provide a guide for the assembly of the trap.

(15) To assemble the trap, the following steps are needed. First, mix a desired amount of water, sugar and yeast. As shown in the figure, the upper container 11 has two marks on it. One of a one-gallon mark 20 and the second is a two-gallon mark 21. More water and yeast yields more CO.sub.2. In the preferred embodiment, two gallons of water at 100 F. mixed with 6 cups of sugar and 3 tablespoons of yeast are used. It is important to measure the levels accurately and to monitor the temperature. When the water reaches 100 F., put the lid 11a with the airlock 17 in place (and filled according to the marks on the airlock) on the upper container. The temperature of the water should be between about 105 and 107 degrees F. to produce optimum levels of CO.sub.2. However, a temperature above 111 degrees F. will kill the yeast and stop CO.sub.2 production.

(16) Next, attach the hose 16 to the airlock and place the upper container into the middle container 12. As this point, the heating pad 12b is turned on. Note that the hose 16 is already installed in the middle container and runs out the bottom of the middle container as shown in FIG. 2.

(17) Next, the lower container 13 is placed in the holding container 14. Note that, if desired, a quantity of diatomaceous earth can be added to the holding container. Then the upper and middle container are placed on the lower container 13, ensuring that the hose 16 extends down into the lower container 13. The trap is now assembled and ready for operation.

(18) Bedbugs are attracted to the device and will climb the outer surface of the holding container 14. Once inside, the slick surface keeps them within the holding container. Bedbugs may also enter the lower container as well. All trapped bedbugs can be disposed of and the trap parts cleaned and reset. In this way, bedbugs can be conveniently and assuredly trapped and destroyed.

(19) In the preferred embodiment, the containers are large (up to five gallons for the top container). However, the device may be made in any size. For example a small travel unit with a top container of the quart size can be used, if desired, in a hotel room, for example.

(20) Although not as effective as the larger units, it can help and, if nothing else, can provide peace of mind.

(21) The present disclosure should not be construed in any limited sense other than that limited by the scope of the claims having regard to the teachings herein and the prior art being apparent with the preferred form of the invention disclosed herein and which reveals details of structure of a preferred form necessary for a better understanding of the invention and may be subject to change by skilled persons within the scope of the invention without departing from the concept thereof.
