Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an aerosol for controlling termites.

[0002]

2. Description of the Related Art When termites are exterminated in a house that has been attacked by termites, termite passages (ant trails) are formed inside and on the surface of walls, wood, soil, and the like. In order to control termites, a method of perforating wood or soil and injecting a pesticide into the interior through a nozzle has been widely adopted.
However, when conventional termites are applied to houses,
In a wide range of exterminations, sufficient extermination cannot be expected unless the drug is injected from a number of locations.In addition, the inner walls of the ant path and termite habitat are woody inside wood, and termite secretion in soil. Since it is made of soil hardened with liquid, even if the drug is applied, the drug permeates the inner wall, and as a result, a large amount of the drug needs to be injected to obtain a satisfactory control effect. Is the current situation. Further, since it is difficult to inject a large amount of medicine from a large number of places into a wall or ceiling in a house, sufficient treatment may not be performed in some cases.

[0003]
