Description

[Technical Field]

[0001] The present invention relates to a bird trap and a method of trapping birds using the bird trap. [Background technology]

[0002] BACKGROUND ART As described in Patent Document 1, a bird trap for capturing harmful birds such as pigeons has been known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3188488 Summary of the Invention [Problem to be solved by the invention]

[0004] There is still room for improvement in techniques for effectively capturing birds.

[0005] The present invention has been made in consideration of the above circumstances, and its main object is to provide a bird trap that can effectively capture birds, and a bird capturing method using the bird trap. [Means for solving the problem]

[0006] In order to solve the above problems, the bird trap of the present invention comprises: A bottom plate portion; a peripheral wall portion extending upward from the bottom plate portion; a ceiling portion that closes an upper side of the peripheral wall portion; Equipped with The peripheral wall portion and the ceiling portion are formed in a lattice pattern, A bird trap that captures and stores birds in a storage space surrounded by the bottom plate portion, the peripheral wall portion, and the ceiling portion, The peripheral wall portion has an opening formed therein through which birds can enter, an opening / closing part whose upper side is rotatably supported and whose rotation opens and closes the opening part; the opening / closing unit is allowed to rotate from a closed position that closes the opening toward the inside of the storage space, while being restricted from rotating from the closed position toward the outside of the storage space, The bird trap further includes a shielding portion that is provided on top of at least one of the ceiling portion and the peripheral wall portion and that shields the storage space from the outside of the bird trap. [Effects of the Invention]

[0007] The opening / closing part is allowed to rotate from a closed position that closes the opening toward the inside of the storage space, so that birds can be led into the storage space through the opening and captured. On the other hand, the opening / closing part is restricted from rotating from the closed position toward the outside of the storage space, so that birds captured in the storage space can be prevented from escaping.

[0008] In addition, the enclosure space is shielded from the outside of the trap by a shielding part that is provided on top of at least one of the ceiling part and the peripheral wall part, which allows birds to enter the enclosure space with peace of mind, making it easier to guide the birds into the enclosure space.

[0009] Furthermore, since the enclosure is shielded from the outside of the trap, the birds trapped in the enclosure can be kept calm. In this case, birds outside the enclosure can be made less wary of the enclosure, making it easier to lead birds from outside into the enclosure.

[0010] As a result, it is possible to effectively capture birds in the storage space. [Brief explanation of the drawings]

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the accompanying drawings.

[0013] Hereinafter, one embodiment of a bird trap according to the present disclosure will be described with reference to the drawings. The trap of this embodiment is for capturing and containing harmful birds, specifically pigeons (e.g., turtle doves). The trap is installed, for example, on a balcony or rooftop of a building.

[0014] <About the birdcage itself> As shown in Figures 1 and 2, the bird trap 10 comprises, as elements constituting the birdcage body, a rectangular bottom plate 20, a peripheral wall 30 extending upward from the periphery of the bottom plate 20, and a ceiling 40 closing the upper end of the peripheral wall 30. The bottom plate 20 is made of a surface material on which bait can be placed. The bottom plate 20 is made of, for example, a synthetic resin (e.g., acrylic). Note that Figures 1 and 2 show the bird trap 10 with shielding sheets 111 and 112, which will be described later, removed (this is also the case with Figure 3).

[0015] The bottom plate 20 has a rising wall 21 extending along the periphery of the bottom plate 20. The rising wall 21 prevents food from scattering from the birdcage body to the outside. The peripheral wall 30 extends upward from the inside of the rising wall 21 on the bottom plate 20. The peripheral wall 30 has a square ring shape in a plan view. The ceiling 40 has a rectangular shape. The peripheral wall 30 and the ceiling 40 are made of wire and have a lattice pattern. Pigeons are captured and housed in a housing space 45 surrounded by the bottom plate 20, the peripheral wall 30, and the ceiling 40. The birdcage body is configured to a size that can house a maximum of 5 to 6, 7 to 9, or 10 to 15 pigeons in the housing space 45. For convenience, a portion of the ceiling 40 is not shown in FIG. 1, and the entire ceiling 40 is not shown in FIG. 2.

[0016] <Regarding the opening 32 and the opening / closing portion 50> Of the four-sided peripheral wall portion 30, the front peripheral wall portion 31 provided on the front side has an opening 32 formed therein for pigeons to enter the housing space 45. In this embodiment, the opening 32 is rectangular, specifically a rectangle with its long sides extending horizontally. The opening 32 extends from the middle of the front peripheral wall portion 31 in the height direction to the upper surface 22 of the bottom plate portion 20. The opening 32 is sized to allow adult birds to enter. The opening 32 is also located on one side of the front peripheral wall portion 31 in the width direction (horizontal direction).

[0017] 1 to 3, the trap 10 includes an opening / closing unit 50 that opens and closes the opening 32. The opening / closing unit 50 is configured to be rotatable about an axis (hereinafter referred to as a central axis of rotation) that extends laterally (specifically, for example, horizontally) along the upper end of the opening 32.

[0018] The opening / closing unit 50 includes a plurality of rod-shaped members 51 spaced apart from one another in the direction in which the rotation central axis extends, and a support unit 60 that supports the upper side (specifically, the upper end) of each rod-shaped member 51 so that it can rotate around the rotation central axis. The support unit 60 includes a shaft member 61 extending along the rotation central axis, a fixing unit 62 that fixes the shaft member 61 to the birdcage main body, and a cylindrical spacer 63.

[0019] The shaft member 61 is provided above the opening 32. The shaft member 61 has a circular cross section and is disposed at a predetermined distance L1 toward the housing space 45 from the upper end of the opening 32. The predetermined distance L1 is, for example, 1 to 5 cm, 2 to 4 cm, or 2 to 3 cm. Both ends of the shaft member 61 are fixed to the front peripheral wall 31 by fixing portions 62.

[0020] The rod-shaped member 51 is made of wire, for example, a metal material (e.g., aluminum). As shown in FIG. 4, an insertion portion 52 through which the shaft member 61 is inserted is formed at the upper end of the rod-shaped member 51. The insertion portion 52 is formed by winding the wire and has an annular shape. A spacer 63 is inserted between adjacent insertion portions 52 of the shaft member 61. The spacer 63 is a member that maintains a predetermined distance between adjacent rod-shaped members 51 and restricts movement of the upper end of each rod-shaped member 51 in the direction of the rotation center axis.

[0021] As shown in Fig. 4, each rod-shaped member 51 is inclined at a predetermined angle θ toward the inside of the storage space 45 with respect to the vertical direction. When each rod-shaped member 51 is inclined, the lower end of each rod-shaped member 51 abuts against the bottom plate portion 20 (specifically, the bottom portion 71 of the groove portion 70, which will be described later). In this state, the opening 32 is closed by each rod-shaped member 51. Therefore, in this state, each rod-shaped member 51 (and thus the opening / closing portion 50) is located in a closed position that closes the opening 32.

[0022] According to the above configuration, each rod-shaped member 51 is permitted to rotate from the opening 32 (in other words, the closed position) toward the inside of the storage space 45, while being restricted from rotating from the opening 32 (in other words, the closed position) toward the outside of the storage space 45. In other words, each rod-shaped member 51 is permitted to perform an opening operation, which is a rotational movement in a direction from the opening 32 toward the storage space 45, while being restricted from a closing operation, which is a rotational movement in a direction from the storage space 45 toward the opening 32.

[0023] The predetermined angle θ is an acute angle, and is an angle of 10 degrees or more. Because the rod-shaped members 51 are inclined, the rod-shaped members 51 are easily opened when a bird pushes the rod-shaped members 51 from the outside, making it easier for the bird to enter the accommodation space 45 of the birdcage body.

[0024] Since the lower end of the rod-shaped member 51 abuts against the bottom plate portion 20, it is difficult for birds housed in the housing space 45 to lift the lower end of the rod-shaped member 51. As a result, it is possible to prevent birds from lifting the rod-shaped member 51 and escaping to the outside.

[0025] The weight of the rod-shaped member 51 causes the lower end of the rod-shaped member 51 to abut against the bottom plate portion 20. The inclined state of the rod-shaped member 51 can be maintained by a simple configuration that utilizes the weight of the rod-shaped member 51 and the bottom plate portion 20. This allows the trap 10 to be simplified.

[0026] The lower end of the rod-shaped member 51 is bent to form an arc-shaped portion 53 that is convex downward. In the rod-shaped member 51, a straight portion 54 is formed between the arc-shaped portion 53 and the rod-shaped member 51. The arc portion of the arc-shaped portion 53 abuts against the bottom plate portion 20, thereby reducing the frictional force acting on the rod-shaped member 51 and allowing the rod-shaped member 51 to open smoothly. Furthermore, because the tip of the arc-shaped portion 53 faces diagonally upward, the tip is prevented from digging into the bottom plate portion 20 during the opening operation, allowing the rod-shaped member 51 to open smoothly.

[0027] The predetermined angle θ is, for example, an angle of 20 to 70 degrees, preferably an angle of 30 to 60 degrees, and more preferably an angle of 40 to 50 degrees.

[0028] <Regarding the groove 70> The trap 10 includes a groove 70 extending from the opening 32 toward the storage space 45. The groove 70 is provided in a portion of the bottom plate 20 facing each rod-shaped member 51. The groove 70 includes a flat bottom 71 and a restricting wall 72, and has a U-shaped cross section. The bottom 71 has a rectangular plate shape and is provided on the upper surface 22 of the bottom plate 20. The arc-shaped member 53 of the rod-shaped member 51 abuts against the bottom 71. The restricting wall 72 extends upward from both ends of the bottom 71 in the direction of the rotation axis. When the arc-shaped member 53 of the rod-shaped member 51 abuts against the bottom 71 of the groove 70, the restricting wall 72 of the groove 70 restricts movement of the rod-shaped member 51 in the direction of the rotation axis.

[0029] The grooves 70 are made of a material (for example, synthetic resin or metal) that is more slippery than the bottom plate 20. This allows the rod-shaped members 51 to open more smoothly, making it easier for birds to enter the enclosure space 45. On the other hand, the top surface 22 of the bottom plate 20 is relatively less slippery than the grooves 70. This makes it less likely that food placed on the bottom plate 20 will scatter. As a result, it is possible to prevent the rod-shaped members 51 from malfunctioning due to food getting caught in the grooves 70, for example.

[0030] In order to make it difficult for birds housed in the housing space 45 to lift the rod-shaped member 51 with their beaks, it is desirable to reduce the vertical gap dimension H1 (see FIG. 4) between the tip of the arc-shaped portion 53 of the rod-shaped member 51 and the bottom portion 71. The gap dimension H1 is, for example, 1 mm to 5 mm, 2 mm to 5 mm, 3 mm to 5 mm, or 2 mm to 4 mm.

[0031] The height position of the restricting wall portion 72 is higher than the height position of the tip of the arc-shaped portion 53 when the arc-shaped portion 53 is in contact with the bottom portion 71. Furthermore, the restricting wall portion 72 extends further from the opening 32 toward the storage space 45 than the tip of the arc-shaped portion 53. This makes it possible to prevent birds housed in the storage space 45 from trying to lift the tip of the rod-shaped member 51 with their beaks, thereby preventing pigeons from escaping from the storage space 45 to the outside.

[0032] <Regarding the obstacle member 80 and the water supply device 85> As shown in Figures 1 to 3, the trap 10 is provided with obstacle members 80 for preventing pigeons from escaping to the outside from between the inclined rod-shaped members 51 and the front peripheral wall portion 31. The obstacle members 80 are provided on the upper surface 22 of the bottom plate portion 20 in an area surrounded by the rod-shaped members 51 and the peripheral wall portion 30 on both ends. In this embodiment, the obstacle members 80 are needle-shaped members made of stainless steel.

[0033] Trap 10 is equipped with water supply device 85. Water supply device 85 is placed on bottom plate portion 20 of storage space 45 and supplies drinking water to pigeons housed in storage space 45. The tank of water supply device 85 stores an amount of water sufficient to supply the pigeons with water for the period from when they are captured in storage space 45 until when they are retrieved.

[0034] In addition, an opening for retrieving captured pigeons and an opening / closing part for opening and closing this opening may be provided in the peripheral wall part 30 other than the front peripheral wall part 31 or the ceiling part 40.

[0035] <About Feeder 90> The trap 10 includes a feeding tray 90. The feeding tray 90 is provided on the bottom plate 20 at a position outside the storage space 45 relative to the opening 32. The feeding tray 90 is rectangular and includes a flat plate 91 having an upper surface 93 on which food is placed, and a feeding tray wall 92 extending along the periphery of the flat plate 91. In this embodiment, the feeding tray wall 92 is made of a surface material. This makes it difficult for food to scatter from the feeding tray 90 to the outside. In this embodiment, the feeding tray 90 is made of wood. The feeding tray 90 is configured to have space for multiple pigeons (e.g., 5 to 6 pigeons) to perch. The feeding tray 90 corresponds to the second feeding tray.

[0036] In this embodiment, as shown in Figure 4, the height position of the upper surface 93 of the flat plate portion 91 that constitutes the feeding tray 90 is the same as the height position of the upper surface 22 of the bottom plate portion 20. This makes it easier to guide birds that land on the feeding tray 90 in search of food toward the bottom plate portion 20.

[0037] <Method of capturing birds using the trap 10> Next, a bird capturing method using the bird trap 10 will be described with reference to FIGS.

[0038] First, the worker sets up the trap 10 in the target location. Then, as shown in Fig. 5, the worker places bird food 100-102 on the upper surface 22 of the bottom plate portion 20 in the accommodation space 45, on the area of ​​the upper surface 22 of the bottom plate portion 20 below the support portion 60, and on the upper surface 93 of the flat plate portion 91 that constitutes the feeding table 90. The worker also replenishes water in the water supply device 85.

[0039] The area below the support portion 60 on the upper surface 22 of the bottom plate portion 20 can be used as the area for placing the bait 101 because the shaft member 61 is positioned at a predetermined distance L1 toward the housing space 45 from the upper end of the opening 32. This makes it possible to effectively provide an area for placing the bait 101 at an intermediate position that is important for guiding the birds into the housing space 45.

[0040] As shown in Figure 5, pigeons 200 are attracted to the feeder 90 by placing food 102 on the flat plate portion 91 of the feeder 90. The pigeons 200 that land on the flat plate portion 91 of the feeder 90 begin to eat the food 102 placed on the feeder 90. Because the feeder wall portion 92 is made of a surface material, it is possible to prevent the pigeons from being captured unsuccessfully due to the food being scattered.

[0041] 6, the pigeon 200 is attracted by the food 101 placed in the lower region of the upper end of the rod-shaped member 51 and starts walking toward the opening 32. At this time, the height position of the upper surface 93 of the flat plate portion 91 constituting the feeder 90 is the same as the height position of the upper surface 22 of the bottom plate portion 20, and since there is no step, it is easy to guide the pigeon 200 toward the opening 32. Furthermore, because the food 101 is placed on the upper surface 22 of the bottom plate portion 20, which is relatively non-slip, the food 101 is prevented from scattering toward the groove portion 70 and becoming caught between the lower end of the rod-shaped member 51 and the groove portion 70. As a result, malfunctions of the rod-shaped member 51 can be prevented.

[0042] As shown in Figure 7, the pigeon 200 enters the accommodation space 45 of the birdcage body while opening the rod-shaped member 51. At this time, the arc-shaped portion 53 of the rod-shaped member 51 is in contact with the bottom 71 of the groove 70, so that the rod-shaped member 51 can be opened smoothly.

[0043] The pigeon 200 is attracted by the food 100 placed in the storage space 45 and moves further in. When the pigeon 200 moves in to a certain extent, the rod-shaped members 51 close under their own weight, as shown in Figure 8, and the arc-shaped portions 53 of the rod-shaped members 51 come into contact with the bottom 71 of the groove portion 70. As a result, the rod-shaped members 51 and the obstacle members 80 block the space between the storage space 45 of the birdcage body and the opening 32. As a result, the pigeon 200 cannot get out of the storage space 45 of the birdcage body.

[0044] After a predetermined number of days (for example, one week) have passed since the trap 10 was installed, the worker retrieves the pigeons 200 that have been captured and housed in the housing space 45.

[0045] During the period until the trapped pigeons are retrieved, the pigeons can drink water from the water supply 85. This prevents pigeons from dying during the period from when the trap 10 is set until the pigeon retrieval work is carried out. As a result, it is possible to prevent the sanitary conditions in the cage space 45 of the birdcage body from deteriorating.

[0046] <About the shielding sheets 111 and 112> Here, the trap 10 of this embodiment further includes shielding sheets 111, 112 that shield the storage space 45 from the outside of the trap 10. The configuration of the shielding sheets 111, 112 will be described below with reference to Figs. 9 and 10. Fig. 9 is a perspective view showing the trap 10 with the shielding sheets 111, 112 attached. Fig. 10 is a perspective view showing the trap 10 with the first shielding sheet 111 removed from Fig. 9. In other words, Fig. 10 is a perspective view showing the trap 10 with the second shielding sheet 112 attached. For convenience, part of the ceiling 40 is not shown in Fig. 10.

[0047] As shown in Figures 9 and 10, the trap 10 includes a first shielding sheet 111 provided on the ceiling 40 and a second shielding sheet 112 provided on the peripheral wall 30. Both the first shielding sheet 111 and the second shielding sheet 112 are made of black sheets with black surfaces and have light-blocking properties. Each of the shielding sheets 111, 112 is made of, for example, resin or paper. The first shielding sheet 111 corresponds to the first shielding portion, and the second shielding sheet 112 corresponds to the second shielding portion.

[0048] The first shielding sheet 111 is provided on the outside of the ceiling portion 40, that is, overlapping the upper side of the ceiling portion 40. The first shielding sheet 111 is provided across the entire area of ​​the ceiling portion 40. The first shielding sheet 111 shields the storage space 45 from above. The first shielding sheet 111 is attached to the ceiling portion 40 using, for example, a cable tie. The first shielding sheet 111 may also be attached to the ceiling portion 40 using adhesive tape, adhesive, or the like.

[0049] The second shielding sheet 112 is provided overlapping the outer side of the peripheral wall portion 30. The second shielding sheet 112 is provided only on a part of the peripheral wall portion 30. The second shielding sheet 112 shields the storage space 45 from the sides. The second shielding sheet 112 is attached to the peripheral wall portion 30 using, for example, a cable tie. The second shielding sheet 112 may also be attached to the peripheral wall portion 30 using adhesive tape, adhesive, or the like.

[0050] To explain the second shielding sheet 112 in more detail, the peripheral wall 30 has four side walls 30a to 30d that form its four surfaces. Each of the side walls 30a to 30d of the peripheral wall 30 includes two side walls 30a, 30b on the long sides and two side walls 30c, 30d on the short sides. Of the side walls 30a to 30d, the side wall 30c forms the front peripheral wall 31 described above.

[0051] The second shielding sheet 112 is provided across one of the side walls 30a on the long side and one of the side walls 30c on the short side. In this case, the second shielding sheet 112 is provided on each of the side walls 30a, 30c over the entire height range from the top end of the rising wall 21 to the top end of the side walls 30a, 30c. The second shielding sheet 112 is provided over the entire area of ​​the side wall 30a on the long side, but is provided only over a portion of the width of the side wall 30c on the short side. More specifically, the second shielding sheet 112 is provided only in the area of ​​the side wall 30c on the short side that is laterally adjacent to the opening 32.

[0052] The portion of the peripheral wall 30 where the second shielding sheet 112 is not provided is a non-shielding portion 115. In the non-shielding portion 115, the inside and outside of the storage space 45 are in communication. Therefore, the storage space 45 can be ventilated through the non-shielding portion 115.

[0053] It should be noted that instead of providing one second shielding sheet 112 across each of the side walls 30a, 30c, a plurality of second shielding sheets 112 may be provided individually on each of the side walls 30a, 30c.

[0054] <About Feeder 120> A feeding tray 120 is provided on the first shielding sheet 111. The feeding tray 120 is formed in a dish shape (square dish shape) and food is placed on the top surface. The feeding tray 120 is provided in a state where it is placed on the center of the first shielding sheet 111. The feeding tray 120 is attached to the ceiling part 40 via the first shielding sheet 111, for example. The feeding tray 120 corresponds to the first feeding tray.

[0055] <How to install the trap 10> The trap 10 is installed, for example, outdoors, against the wall of a building. In this case, the trap 10 is installed so that the non-shielding portion 115 (e.g., side wall portion 30b) faces the wall. In this installed state, the storage space 45 of the trap 10 is shielded by the second shielding sheet 112 from the opposite side of the wall (i.e., the front side) across the trap 10. This has the effect of blocking a person's line of sight toward the storage space 45 from the opposite side.

[0056] <Method of capturing birds using the trap 10 (shielding sheets 111, 112 and feeding table 120)> When using the trap 10 to capture pigeons 200, as described above, the worker performs a preparation step of placing bird food 100-102 on the bottom plate 20 in the housing space 45, on the area of ​​the bottom plate 20 below the support portion 60, and on the feeding tray 90 provided on the bottom plate 20 in the portion of the housing space 45 outside the opening 32 (see FIG. 5). During this preparation step, the worker also places food 103 on the feeding tray 120 on the first shielding sheet 111, as shown in FIG. 11. In this case, since the food 103 is provided on the first shielding sheet 111 (in other words, on the trap 10), the pigeons 200 can easily notice the food 103. This makes it easier to lure the pigeons 200 onto the trap 10.

[0057] Furthermore, since the storage space 45 cannot be seen from above the first shielding sheet 111, the pigeons 200 can be safely lured to the bait 103. Therefore, in this respect as well, it is easier to lure the pigeons 200 onto the trap 10.

[0058] Furthermore, because the bait 102 on the feeder 90 is provided outside the storage space 45, pigeons 200 that are lured onto the trap 10 can easily notice the bait 102. This makes it easier to lure pigeons 200 to the bait 102. This makes it easier to capture pigeons 200 by guiding them in the order of bait 103 on the trap 10 → bait 102 on the feeder 90 → opening 32 → storage space 45.

[0059] <Effects of the shielding sheets 111 and 112> Since the housing space 45 is shielded by the shielding sheets 111, 112, the pigeons 200 can enter the housing space 45 with peace of mind. This makes it easier to lead the pigeons 200 into the housing space 45. Also, since the housing space 45 is shielded, the pigeons 200 captured in the housing space 45 can be made to calm down. In this case, the pigeons 200 outside the housing space 45 can be made to relax their wariness of the housing space 45. This makes it easier to lead the pigeons 200 outside into the housing space 45.

[0060] As a result, it is possible to effectively capture the pigeon 200 in the storage space 45.

[0061] Pigeons 200 dislike being attacked from above, and are therefore particularly wary of anything above. In this regard, the housing space 45 is shielded from above by the first shielding sheet 111, which makes it easier for the pigeons 200 to feel a sense of security. This makes it easier to lead the pigeons 200 into the housing space 45.

[0062] The housing space 45 is shielded from the sides by the second shielding sheet 112. In this case, it is possible to block people's views from the sides toward the housing space 45. This allows the pigeons 200 to enter the housing space 45 more safely, making it easier to guide the pigeons 200 into the housing space 45.

[0063] Because the second shielding sheet 112 is provided only on a portion of the peripheral wall 30, heat in the accommodation space 45 can be discharged to the outside through the non-shielding portion 115 of the peripheral wall 30 where the second shielding sheet 112 is not provided. This prevents heat from building up in the accommodation space 45. This prevents the captured pigeons 200 from dying early due to heat, and the water in the water dispenser 85 from spoiling early due to heat.

[0064] The surface color of the shielding sheets 111, 112 is black, which enhances the light-blocking properties of the shielding sheets 111, 112. In this case, it is possible to prevent light from entering the housing space 45. This makes the pigeons 200 feel more secure, and as a result, it is easier to guide the pigeons 200 into the housing space 45.

[0065] Since the water supply device 85 is covered from above by the first shielding sheet 111 having light-blocking properties, the water in the water supply device 85 can be prevented from spoiling early due to the heat of sunlight.

[0066] <Other embodiments> The above embodiment may be modified as follows.

[0067] Depending on the installation location of the trap 10, part or all of the trap 10 may be covered from above by a canopy or the like. For such a trap 10, the first shielding sheet 111 may be provided only on part of the ceiling portion 40, or the first shielding sheet 111 may not be provided on the ceiling portion 40.

[0068] In the above embodiment, the second shielding sheet 112 is provided on two surfaces of the peripheral wall 30, but the second shielding sheet 112 may be provided on only one surface of the peripheral wall 30, or on three surfaces. Also, the second shielding sheet 112 may not be provided on the peripheral wall 30. How the second shielding sheet 112 is provided on the peripheral wall 30 may be determined appropriately depending on the installation environment of the trap 10 (presence or absence of walls, installation condition of the walls, etc.).

[0069] The shielding sheets 111, 112 may be attached to the ceiling 40 and the peripheral wall 30 at the installation site of the trap 10. In this case, the installation environment at the installation site is first checked. For example, the presence or absence of walls and eaves at the installation site is checked. Next, based on the confirmed installation environment, the shielding sheets 111, 112 are attached to the ceiling 40 and the peripheral wall 30. For example, in an installation environment without eaves, the first shielding sheet 111 may be attached to the entire ceiling 40.

[0070] In the above embodiment, the shielding portion that shields the accommodation space 45 is formed in a sheet shape (specifically, the shielding sheets 111 and 112), but the shielding portion may also be formed in a plate shape.

[0071] The surface color of the shielding sheets 111 and 112 is not limited to black as long as it is a dark color. For example, it may be brown or dark gray.

[0072] The feeding tray 120 does not have to be provided on the first shielding sheet 111. In this case, the feeding material 103 can be placed directly on the first shielding sheet 111 during the preparation process.

[0073] A heat insulating sheet may be wrapped around the water supply device 85. This will further prevent the water in the water supply device 85 from spoiling early due to the heat of sunlight.

[0074] The configuration of the opening / closing unit 50 is not necessarily limited to that of the above embodiment. For example, the opening / closing unit may be formed in a plate shape, and the upper side of the opening / closing unit may be supported rotatably to open and close the opening 32. In such a configuration, a restricting unit (stopper) is provided to restrict the opening / closing unit from rotating from the closed position toward the outside of the storage space 45. This allows the opening / closing unit to rotate from the closed position toward the inside of the storage space 45, but restricts its rotation from the closed position toward the outside of the storage space 45.
