Since the power sprayer described in Patent Document 1 sprays a pest control agent on the entire plant, the pest control agent scatters around the plant. Therefore, work carefully in consideration of the influence on the surrounding environment such as the human body. Must.
In addition, the power sprayer is large and difficult to handle, and the cost is high, which is not preferable as a pest control apparatus that a general person performs in a home garden.

From the above, it is conceivable to use the aerosol container disclosed in Patent Document 2 to eject the contents toward the pests adhering to the plant to control the pests.
Since this aerosol container is a simple one that can be used anywhere, it is preferable as a pest control apparatus that a general person performs in the garden of a house.
However, the aerosol container ejects the contents as fine particles at high speed, so if it is ejected from the vicinity of a pest adhering to the plant, the pest is blown away by the contents, so it is separated from the pest adhering to the plant. Since the contents are ejected from the position toward the pests so that the pests are not blown away by the contents, only a part of the ejected contents are blown to the pests, and most of the rest is scattered around , Pest control efficiency is poor.
In addition, since most of the contents ejected as fine particles are scattered around as described above, it is necessary to work carefully in consideration of the influence on the surrounding environment such as the human body.

The main body 1 a has a suction port 2 and a discharge port 3, and an air flow passage 4 that communicates the suction port 2 and the discharge port 3.
The air flow passage 4 is provided with a fan 5 and a drug carrier 6. When the fan 5 is driven by a motor 7, air is sucked from the suction port 2, and the air touches the drug carrier 6 to control pests. The air containing the component is discharged, and the air is discharged from the discharge port 3 and diffused into the air from the nozzle portion 1c.

The pest control component contained in the air diffused from the nozzle portion 1c into the air is made into fine particles. In addition, a fine particle is smaller than the particle | grains of the content ejected in the case of an aerosol container.
That is, the pest control component is diffused into the air as fine particles.
In addition, the flow rate and flow rate of the air diffused from the nozzle portion 1c into the air is slower than the ejection speed of the contents of the conventional aerosol container, and the ejection amount is small. Pests attached to plants are not blown away.
That is, by adjusting the air discharge speed by the fan 5 and the like, it is possible to arbitrarily control the above-described air flow rate and the like, so that the flow rate of air diffused from the nozzle portion 1c into the air is arbitrary. Is possible.
