DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an attractant bait for controlling pests.

[0002]

2. Description of the Related Art It is common practice to use poison baits as pesticides for insects such as cockroaches. However, the edible nature of such poisonous baits by insect pests is not always good, and the control efficiency may not be sufficient.

[0003] Therefore, an object of the present invention is to provide an attractant poison bait excellent in eating ability of pests such as cockroaches.

[0004]

The present invention has solved the above-mentioned problems by including a branched dextrin.

[0005] When a branched dextrin is contained, the attractiveness of pests and the edibility of the attractant poison bait for pest control by pests are improved, and the pest control effect is improved.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. The insect poison attractant bait according to the present invention is a poison bait containing branched dextrin.

[0007] Pests to be treated with the attractant poison bait include cockroaches such as cockroaches, German cockroaches, black cockroaches, black ants, brown ants, brown ants, petrels, house worms, terrestrial algae, amimeari, himeari, giant ants, giant ants, black ants, and the like. Ants such as ant and carpenter ant; tobacco beetles such as tobacco beetles; Examples include various arthropods such as insects, crustaceans such as paddy beetles, and slugs. The attractant poison bait contains the branched dextrin and an insecticidal component.

[0008] The branched dextrin is obtained by heating and branching starch or soluble starch. Specific examples include yellow dextrin obtained by heating and branching white dextrin, which is generally called dextrin, obtained from starch or soluble starch, and British gum obtained by directly heating and branching starch.

The use of these branched dextrins improves the attraction and eating ability of the above-mentioned pests. In particular, as shown in Examples described later, when a branched dextrin such as yellow dextrin or British gum is used, the attraction and eating properties are improved as compared with the case where a white dextrin is used.
Although the reason is unknown, it is considered that the branch generated in the dextrin affects the attraction and the eating ability. Examples of the above starch include starch from corn, potato, sweet potato, wheat, rice, tapioca and the like.
