Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest control agent and a pest control device which can be applied to control flying pests.

[0002]

2. Description of the Related Art Generally, in order to control flies, mosquitoes, flies and other harmful insects that have entered livestock and poultry houses, restaurants, etc., organic phosphorus compounds such as dichlorvos and trichlorfon, propoxur, bassa, etc. Carbamate compounds,
BACKGROUND ART Liquids containing insecticidal active ingredients such as pyrethroid compounds such as allethrin, resmethrin, and permethrin-cisulthrin have been sprayed onto the floor surface, wall surface, ceiling surface, or sprayed into the space.

However, even if a liquid drug is sprayed in the air, it has only a temporary exterminating effect, and since it gives an opportunity to bring a sublethal amount of drug into contact with a pest, the adult or its progeny is resistant to the drug. There is a harmful effect. For this reason, in recent years, a pest control device in which a solid or viscous semi-solid drug is put in a container is installed on the floor or the like so that a lethal amount of the drug is sufficiently contacted or fed. .

[0004]

However, the solid or semi-solid drug has a problem that it requires a complicated work of periodically replacing or replenishing the drug with reduced efficacy.

Further, since the above-mentioned pest control device needs to be installed in a relatively horizontal place so that the medicine does not overflow, there is a problem that the application place is limited.
If it is installed in a horizontal position at a low position such as a floor surface against flies, carcasses of insects are likely to accumulate in the container, which is also unsanitary.

Therefore, the first object of the present invention is to solve the above-mentioned problems and to limit the place of application, and especially a pest control agent or pest control which can be installed in an indoor space suitable for controlling flying pests. The equipment is to make the pest carcasses hygienic.

A second object of the present invention is to provide a pest control device which is simpler in the work of periodically replenishing the medicine and which is less frequently performed.

[0008]

In order to solve the above-mentioned first problem, in the present invention, a pest obtained by impregnating a molded body made of a water-absorbent material with a liquid pesticide containing an insecticidal component and a pest attractant component is used. It was used as a pesticide.

Alternatively, a water-absorbent material is impregnated with a liquid pesticide containing an insecticidal component and a pest-attracting component, and the pest-control device is filled in a basket-like container that can be suspended.

In order to solve the first problem and the second problem, the pest control device described above is provided with
It was equipped with a continuous feeder that dripped or leached the pesticide from the auxiliary tank through a thin tube.
