AI Technical Summary

Benefits of technology

The present invention is a parasite- and hygienic pest-controlling composition that can effectively control harmful parasites and hygienic pests that can parasitize animals and humans. The composition can be used on a wide range of animals, including companion animals, pet animals, domestic animals, and fowls. The parasites that the composition can control include ecto-parasites (such as lice, flies, and mites) and endo-parasites (such as worms and blood flukes). The composition can be applied to the skin, hair, or organs of the host animal, and it can help promote healthy growth and prevent serious diseases and death caused by parasites.

Problems solved by technology

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.
