Abstract: PURPOSE:To provide a termite control agent prevented from the high humidity or dryness of air under a floor by carrying a termite controlling ingredient on clay porous granules selected from sepiolite, attapalgite and allophane having a humidity-adjusting function. CONSTITUTION:A termite-control agent comprises a termite-controlling ingredient (an organophosphorous, carbamate or pyrethroid insecticide is employed) carried on a carrier consisting of at least one kind of clay porous granules selected from a group of sepiolite, attapalgite and allophane which absorb moisture under a high humidity and release the moisture under a dry condition to adjust the humidity in response to the humidity of an environment. The agent may be further mixed with the same clay porous granules as the carrier as a humidity-adjusting component. Since the agent does not require water when employed, the agent does not give moisture to air under a floor or in a living space to prevent the generation of molds or rot bacterial after employed. Emulsions, capsules, etc., containing the agent can be also applied on underfloor concrete to prevent the invasion of the termites due to the dry contraction of the concrete.
