Chemical agents are conventionally used to control or prevent termites. Potent agents such as organophosphorus compounds have been used. A termite control agent is provided that is not only high in control effect against termites but also safe to the human body. This is achieved by a termite control agent comprising particles containing two or more kinds of oxide or hydroxide which contain at least one kind of each of a first component and a second component, wherein the first component consists of zinc oxide or zinc hydroxide, and the second component consists of at least one kind of oxide or hydroxide of magnesium, calcium and aluminum.
