2. Description of the Related Art Since pest baits for controlling pests such as cockroaches are widely used in ordinary households, children and pets may accidentally eat them. Therefore, a pest entry port provided on the side or top surface of the container of the pest bait storage container is required to have a size such that a human finger or the like does not easily enter the container, and the container is required to have a strong structure that is not easily broken. You. On the other hand, in order to increase the control efficiency of pests, it is necessary to attract more pests into the container. Since the pest entry port provided in the container also plays an important role as a volatilization port for attracting components contained in the poison bait, etc., in order to effectively volatilize the attracting components, for example, the opening area of the container should be as large as possible. good. However, increasing the opening area of the container is limited because the insect pest bait storage container needs to have a structure for preventing accidental eating, so that the attraction of the attracting component may not be sufficiently exhibited.

[0003] Conventionally used pest bait storage containers are classified into a type in which a pest entry port is provided on a side surface of the container and a type in which a pest entrance is provided on an upper surface of the container. In the former type, there is a case where the attraction component does not volatilize efficiently because the attraction component stays in the container, and the attraction is not necessarily sufficient. The latter type not only increases the risk of accidental ingestion, but also causes the attractive components to evaporate in a short time,
The attraction was insufficient.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an insect pest bait container excellent in both accidental feeding prevention and pest attraction.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A pest bait storage container according to the present invention is a pest bait storage container having a pest entry port and a poison bait storage section inside, wherein a volatilization port for a pest attraction component is provided on the surface of the container. Features. The pest bait storage container of the present invention is provided with a bait storage section in which the bait is stored, so that the pests and the like cannot directly touch the bait from outside the container, and the pests enter through the pest entry port. And come in contact with the bait.

[0008] The position of the volatilization opening of the pest attracting component provided in the pest bait bait storage container of the present invention is not particularly limited. It is preferably provided on the upper surface of the container at a higher position than the stored bait. As a result, the volatile components of the attraction component volatilize upward. If the volatilization opening is at a position lower than the poison bait, the volatile component is likely to remain in the container, and it is difficult to efficiently volatilize out of the container. Therefore,
In a preferred embodiment of the insect pest bait storage container of the present invention, a pest entry port is provided on a side surface of the container, and a volatile port is provided on an upper surface of the container.

[0009] The shape of the volatilization opening is not particularly limited. For example, shapes such as a circle, an ellipse, a slit, and a polygon are mentioned, and a circle or a slit is preferred from the viewpoint of moldability and strength. When the volatilization port is circular, the size of the volatilization port is 0.5 to 3.0 in terms of the volatilization efficiency and the prevention of accidental eating.
mm. When the shape of the volatilization opening is not circular, the size of the volatilization opening is appropriately determined to such an extent that volatilization is possible and accidental eating can be prevented, and is not particularly limited. Moreover, the total opening area of the volatilization opening is 3.5 to 35.5 m from the viewpoint of the volatilization efficiency.
m ² , more preferably 8.5 to 25.0 mm ² . The number of volatilization ports is not particularly limited, but is preferably 2 to 10 from the viewpoint of the robustness of the container and the efficiency of volatilization.

[0010] In the pest bait storage container of the present invention, the upper surface of the container provided with a volatilization port may be flat (FIG. 1), or as shown in FIG. The dome portion 1 may be provided, and the dome portion may be provided with the volatilization opening 2. In the latter case, in particular, those where the vents are arranged at an equal distance from the center of the dome can efficiently attract pests,
More preferred. This is considered to be due to the following dome effect.

That is, the volatilized volatile component first stays inside the dome and, after reaching a saturated state, is gradually pushed out of the container from the volatilization opening (dome effect). Due to the dome effect, the volatile components are released rapidly, and the volatile components are not released very slowly at the concentration where the attraction effect is not sufficiently exhibited. Is volatilized out of the container over a suitable time. In addition, it is more preferable that the volatilization port is arranged at an equal distance from the center of the dome, because the volatile component volatilizes uniformly in each direction outside the container.

In the pest bait storage container of the present invention, the bait 3 containing the pest attractant is stored in the bait storage unit 4 and is used for extermination of the pests. In the present invention, the pests to be controlled include, for example, cockroaches: black cockroaches, German cockroaches, cockroaches, yamato cockroaches, etc .;
Various pests such as duck beetles can be mentioned.

There is no particular problem in the poison bait as long as it contains components used for controlling the above-mentioned pests.
For example, boric acid dumplings or dumplings containing various pyrethroid insecticides, organophosphorus insecticides, carbamate insecticides, and the like can be mentioned.

The pest-inducing component is not particularly limited, but preferably includes plant foods, animal foods, saccharides, and the like, which serve as bait for the pests. These may be either solid foodstuffs or liquid foodstuffs. Examples of vegetable ingredients include peanut powder, peanut oil, sesame powder, sesame oil,
Rice bran, onion powder, sake lees, and the like. Animal foods include, for example, pupa, fish meal, butter and the like. Examples of the saccharide include sucrose, trisaccharide, brown sugar, honey and the like. The amount of these attractants is not particularly limited, but is preferably 0.5 to 10.0% by weight in the poison bait.

Further, the pest poison bait storage container of the present invention may be formed by mixing a pest attraction component into the material of the container in order to further enhance the pest attraction effect. The material of the container is not particularly limited, but resins used for ordinary plastics, such as polystyrene resin, polypropylene resin, polyethylene resin, and polyvinyl chloride resin, which are molded by injection molding or vacuum molding, are preferred. . The amount of the attraction component is preferably 0.1 to 5.0% by weight in the material of the container.

In the present invention, in addition to the above-mentioned attractant components, other components may be appropriately blended into the material of the container as long as the attraction of pests is not impaired. For example, bitter agents such as denatonium benzoate, silica gel, wood flour, and starch and other inorganic and vegetable substances that increase the retention of inducing components,
A bactericide as a cleansing agent and the like can be mentioned.

The method for producing a pest bait storage container of the present invention comprises:
There is no particular limitation, and it can be easily manufactured by ordinary plastic molding. The same applies to the case where the above-mentioned attractant component and the like are added and blended into a resin which is a material of a container to form a desired shape. In this case, when the attraction component is a solid food material, it is preferably finely pulverized, and when it is a liquid food material, it is preferable to impregnate it with a mineral substance such as silica gel. Then, after the attraction component and the like are added and compounded, it is formed into a desired shape by injection molding or vacuum molding.

The pest bait storage container of the present invention obtained in this way is not a device of the bait itself as in the prior art, but is a device of the container itself to prevent accidental eating while improving the volatility of the attraction component. It can be retained or further imparted to the container itself to improve pest control. Many pests, such as cockroaches, often react to quite familiar odors, so they are first invited to a container, and then to the bait odor to eat and die.

Next, a specific example of the pest bait storage container of the present invention will be described with reference to the drawings. 3 shows an example in which the upper surface of the container has a flat shape, and FIG. 4 shows an example in which the container has a dome shape on the upper portion. The container shown in FIGS. 3 and 4 comprises a container body and a lid, in which (A) is a plan view of the container body before assembly, (B) is a plan view of the lid before assembly, and (C) is a container after assembly. (D) and (E) show the container assembly overhead view. The container main body is provided with a column 6 for supporting a lid 8 on a bottom plate 10 and a partition member 7 for a bait storage section for forming the bait storage section 4, and is arranged such that the central portion of the bottom plate 10 becomes the bait storage section 4.
