[0003]

[Problems to be Solved by the Invention] The control of termites and the like can be broadly divided into two steps, namely, a wood portion coating treatment for controlling termites by applying it to a wood portion, and a soil treatment for controlling a soil by applying a chemical solution to the soil under the floor. There are many types, and in existing houses, it is often difficult to apply the method to apply wood to the underfloor, etc., and soil treatment is often used, but termites often penetrate the chemical treatment layer and cause harm, There is a demand for a termite control agent for soil treatment, which has both direct anticidal power and chemical treatment layer penetration blocking power. The present inventors are keen to create a new termite control composition for soil treatment, which has a remarkable anticidal effect against termites that damage woods such as houses and furniture and a chemical treatment layer penetration inhibiting effect. As a result of repeated studies, it was found that by combining the compound A described in the above-mentioned prior art and a carbamate compound, a remarkable synergistic effect, which cannot be predicted from the effects of each used alone, is exhibited, and the present invention has been completed. Is.
