TECHNICAL FIELD The present invention relates to a composition for controlling termites and a method for controlling termites using the composition.

The present invention relates to a composition for controlling termites and a method for controlling termites using the same.

Termites are the insects that damage the pillars and other structural materials of wooden buildings by damaging the termites. Structural materials damaged by termites cause structural instability of buildings with their functions. Termites that cause deadly damage to wooden buildings are insects living in sub-tropical regions and not found in the country. Recently, termites have become active due to global warming and imported timber. In addition, termites are social insects that live in colonies. The termites have the same size of wings, male termites do not die after fertilization, and because they live with female termites that spawn, It is distinguished from logging. The growth is incomplete metamorphosis, and the big jaw is chewing type and the gecko is well developed. Termites consist mainly of reproductive classes, many workers classes, nymphs, troop ant classes, young termites, and eggs.

Among these termites, Japanese termite (Reticulitermes speratus), which is a kind of underground termite, lives mainly in Korea. Japanese termites are confirmed throughout Korea, and termite feeding activity has been confirmed in the northern part of South Korea in Seoul Gyeonggi Province. Generally, if damage is caused by termite damage in a building, a hollow phenomenon occurs in which the inside of the nacelle is already hollowed out even though no change can be found in the appearance of the building.

The Japanese termites (Reticulitermes speratus) inhabited in Korea are greatly affected by global warming and their population is greatly increased, and damage to wooden buildings is very severe. The distribution height is gradually increasing, and there is a sign of diffusion. In terms of ecology, termites exhibit similar characteristics to cockroaches, and when they breed and secure their habitat in the ground or wood, their control is extremely difficult. Their habitat is mainly in the ground and in the wood, There is considerable damage already under way.

The current termite research focuses on the ecology of the termites, the status of the damage, and the measures to follow. Currently, most of the technologies used for termite control depend on foreign countries. Therefore, there is a need for a composition for controlling termites suitable to the situation in Korea.
