  There are two types of control of white ants, such as xylem application treatment that applies chemicals to xylem to control white ants and soil treatments that apply chemicals to the soil under the floor to control them. In houses, etc., the treatment method applied to the wood under the floor is often difficult, and soil treatment is often used, but white ants often penetrate the chemical treatment layer and cause damage, and direct ant killing power. In addition, a white ant control agent having a chemical treatment layer penetration preventing power is desired.

  The present inventors have conducted intensive research to create a novel white ant control composition having a remarkable anticide effect and a drug treatment layer penetration preventing effect against white ants that harm wood such as houses and furniture. As a result, by combining α- (α, α, α-trifluoro-m-toluoyl) -p-tolunitrile 4- (p-trifluoromethoxyphenyl) semicarbazone (chemical name, compound A) and a pyrethroid compound, The present invention has been completed by finding out that it has a remarkable effect that cannot be predicted from the effects when used independently.
