Benefits of technology

[0014]It is an important subject to expel harmful parasites that parasitize animals in order to maintain health of the targeted animals, and also in order to produce stably safe foods, or living materials such as high quality wool, feather, leather or the like, in case where the target animals are domestic animals and domestic fowls. On the other hand, it is also an important subject to expel hygienic pests in human living environment in order to maintain human healthy living environment, for example to prevent the spread of infection transmitted by hygienic pests, to prevent pollution of foods by contact with hygienic pests, or to prevent causing harm on clothes or residences, etc. by hygienic pests, and the like. From such a viewpoint, hitherto, parasite-controlling agents and hygienic pest-controlling agents for expelling harmful parasites and hygienic pests have been developed, and effective agents have been practically used until now.

[0015]However, as those agents have been used over the years, recently parasites and hygienic pests have acquired resistance to those agents, the scenes that it becomes difficult to expel with the agents that have been hitherto used have increased. Under such situations, it is expe
