なった。[Conventional techniques and issues] In recent years, the damage caused to houses and trees in Japan by Japanese ants has become enormous. For this reason, various studies have been conducted on its control, and various termite control agents (termite control agents) have been used so far.
is put into practical use. First, after the war, DDT, γ-BHC

Termites often live in places where it is difficult to apply termiticides, such as in the soil under floors or in the wood of foundations, so termite control agents need to have an effective termite control effect that lasts for a long period of time. It is. In particular, termite damage frequently occurs under floors, in kitchens, bathrooms, toilets, washrooms, etc., and a product with excellent weather resistance that remains effective for a long period of time is desired even in such places.

．． : There are also problems such as strong inhibition of cholinesterase activity. 9 On the other hand, conventional wood deodorants first started with the use of creosote oil, which is an oil-soluble wood preservative, and later PCP and the like were used, but these also have concerns about environmental pollution. Inorganic systems include 0CA (chromium-copper) system,

Therefore, when wood is treated with this preservative and disposed of, problems arise such as arsenic and hexavalent chromium being volatilized into the air or concentrated in ash5. 11, which has excellent long-lasting efficacy and is highly safe for humans and livestock.
111 Various researches were conducted to obtain an ant control agent.

However, we were able to complete the present invention with the knowledge that it also has the effect of a wood preservative.
