Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is a means for exterminating the harmful insects such as cockroaches, chafers, ants, squid larvae, koga larvae, flea larvae and the like in places where it is desired to prevent inhabitation or invasion of unsanitary or unpleasant insects. The purpose of the present invention is to provide effective pest control.

[0002]

2. Description of the Related Art Various methods for exterminating harmful insects such as cockroaches, which cause a hygiene problem as pathogens and mold vectors, have been developed, and methods such as a residual coating method are widely used. In addition, due to social demands to avoid spreading chemicals over a wide area, one method is to place harmful baits of insect pests containing insecticides at the place where the pests live or in the path of the pests to exterminate the pests. Widely used. further,
In order to prevent human beings from directly touching the drug, a method of putting poison baits in various containers and disposing the baits in a place where the pests live or a path of the pests to exterminate the pests is also widely used. However, the control method using poison bait has a problem that cockroaches do not eat the poison bait (eating tiredness phenomenon) even in a place where the initial effect is observed, and the effect may be reduced. As a method other than feeding poison baits in the process from the method of widely spreading the drug to the point treatment method, a method of treating the drug as a pest by letting the pest pass through the place where the drug is treated is a special feature. It is described in Japanese Patent Publication No. 10-502537. In this method, a tunnel-shaped device having a ceiling treated with a pest control agent is shown. However, this method has no effect on small pests that do not come into contact with the upper part of the tunnel, and it is difficult to exert an effect on cockroaches because only the back part covered with the chitin layer comes into contact, and therefore a large amount of drug is used. It becomes necessary, and the load on the environment becomes high. Furthermore, depending on the formulation, the control agent on the ceiling may fall off. In addition, JP 20
In 01-61397, various insecticides are used to show an insecticidal container which is effective only when an invading pest passes on the inner wall and touches the insecticidal component. Inability to control pests.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention The present invention provides a method for exterminating insect pests which is a hygiene problem by disposing the attractant bait in the place where the insect pests live or in the path of the insect pest. It is an object of the present invention to provide a method for eliminating pests such as cockroaches, which can be treated without direct contact with a drug without causing "sickness".

[0004]

DISCLOSURE OF THE INVENTION The inventors of the present invention have earnestly studied a method for easily and efficiently exterminating harmful insects such as cockroaches. As a result, the neonicotinoid compound is treated in the container and is easy to carry. It was discovered that the insects such as cockroaches can be efficiently exterminated by simply placing them in the habitat or path of the pests, and that the drug-resistant pests that have become a problem in recent years can also be effectively eliminated. The present invention has been completed.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a neonicotinoid compound is placed inside a container having a doorway which is large enough to be placed in a place where pests inhabit and a path for pests and which allows pests to freely enter and leave. It is a method of treating and disinfecting the harmful insects by placing the container in the habitat or passage of the harmful insects.

The present invention can be applied to all pests capable of invading a neonicotinoid compound into a container treated, but the main target is the crawling pests, especially cockroaches.

[0007] The container treated with the neonicotinoid compound is large enough to be placed in a habitat or a passageway of a pest, the pest easily invades, and the drug-treated part is freely contacted.
It has an entrance that allows you to exit. Examples of the shape include a rectangular parallelepiped, a dome shape, a triangular pyramid, a quadrangular pyramid, and the like.
If the size of the bottom is a rectangular parallelepiped, it is 1 to 20 cm in height and 1 in width.
˜30 cm, height 0.5˜5 cm, preferably length 3˜10 cm, width 3˜20 cm, height 0.5˜3 cm. The size and number of doorways will vary depending on the target pest,
When the target pest is a cockroach and the container is a rectangular parallelepiped, it is more preferable that the two places in the longitudinal direction of the container are completely or partially open systems. The material of the container is not particularly limited, but paper and biodegradable resin are more preferable in consideration of economy and environmental aspects such as disposal.

The neonicotinoid compound according to the present invention is not particularly limited as long as the pest passes or contacts the treated part of the neonicotinoid compound. Specific examples include neonicotinoid compounds such as acetamiprid and nitenpyram. The neonicotinoid compound may be directly processed into a container, or may be once formulated into a container such as a microcapsule and then processed into a container. Further, the neonicotinoid compound may be mixed with another insecticide and used. Examples of the insecticide that can be mixed include hydramethylnon, boric acid, dichlorvos, phenthion, organophosphorus compounds such as fenitrothion, propoxur, carbamate compounds such as fenobucarb,
Pyrethroid compounds such as tralomethrin, cyphenothrin, permethrin, etofenprox, silafluofen, diflubenzuron, and rufenuron, phenylpyrazole compounds, phenylpyrrole compounds, insect growth regulators such as methoprene, pyriproxyfen, and the like can be mentioned.

When a pyrethroid compound is added as a mixture, piperonyl butoxide, N- (2-
Ethylhexyl) bicyclo [2,2,1] hept-5-
A synergist of a pyrethroid compound such as ene-2,3-dicarboximide may be mixed and used.

The neonicotinoid compound may be treated as it is with the pest control material of the present invention, or may be treated as a solution or suspension. The solvent is not particularly limited as long as it can suspend or dissolve the neonicotinoid compound and does not repel the target pest, but sugars (molasses, honey), glycerol, vegetable oils and fats,
Animal fats, kerosene, alcohols, piperonyl butoxide, MGK-264 and the like can be mentioned. It is also possible to use a mixture of this suspension or solution with mineral fine powder such as diatomaceous earth, silicon oxide, calcium carbonate, talc and clay. Further, the neonicotinoid compound may be mixed with mineral fine powder such as diatomaceous earth, silicon oxide, calcium carbonate, talc and clay to treat the pest control material of the present invention.

A neonicotinoid compound according to the present invention,
The material of the part for treating the solution, suspension or powder is not particularly limited as long as the neonicotinoid compound, the solution, suspension or powder can be retained, non-woven fabric, paper, cloth, Resin, glass, aluminum, etc. are considered. Also, for example, by holding a solution of the neonicotinoid compound on a non-woven fabric, and preventing the exudation into the control container with an aluminum plate, etc., use two or more types at the same time to make a pest control material that is easier to use. You can also
The shape of the portion treated with the neonicotinoid compound is not particularly limited as long as the neonicotinoid compound, its solution, suspension or powder is retained,
In addition to the flat plate shape, it may have a corrugated shape, a bellows shape, or a mesh shape.

In order to facilitate the contact of the insect pest with the insecticidal part, it is possible to treat the container with an attractant such as a sex pheromone or an aggregate pheromone of the insect pest and a flavor component such as sesame oil.

Further, different insecticides can be simultaneously dispersed and arranged in a container in which the neonicotinoid compound is treated. By treating multiple types of insecticides in this way,
It is possible to cope with contact avoidance behavior due to individual differences of pests and drug resistance.

The pest control material of the present invention is installed in a habitat or a passageway of a pest.

Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the examples.
