Soil treatment is a method of forming a drug layer on the soil surface. More specifically, for example, when a liquid material is to be treated on a soil under the floor of a wooden building that can be intruded by a person, the spray is spread using a power sprayer, and the emphasis is particularly placed on a building base where an ant passage is easily formed. It is better to process. Further, in the case of treating underfloor soil or the like where a person cannot enter such as a bathroom or entrance, a method of piercing with a drill and injecting a drug into the soil from there is adopted. The treatment amount when the composition of the present invention is used for termite control is different depending on the treatment method, formulation form and other various conditions.In general, in the case of soil treatment, the total amount of fenvalerate and compound A is 1 to 100. g / m 2, preferably 5 to 50 g / m 2, the case of wood treatment, is該合weighing
