の使用を疑問視する声が出ている。Although most of the above compounds have relatively low toxicity, some of the organophosphorus and carbamate insecticides have a cholinesterase activity inhibitory effect on the human body, and pyrethroid insecticides have high fish toxicity. There are many things, and it is hard to say that it is sufficiently safe from the viewpoint of environmental pollution. Some of these compounds are commercially available by blending octachlorodipropyl ether (hereinafter referred to as S-421) as a synergist because of problems such as sustained efficacy and price-performance ratio. Many. Although S-421 is an excellent synergist, some have questioned its use as a chlorine-based agent from the viewpoint of environmental pollution.

It has only been known that oleic acid, which is an unsaturated higher fatty acid, has an effect as a composition of a controlling agent or an attractant against sanitary pests such as mites and cockroaches (JP-A-4-342506, JP-A-4-3425
No. 11, JP-A-2-142704). However, oleic acid is an unsaturated fatty acid, and may be oxidized when left in the air to change to a saturated fatty acid, and when applied to wood or the like, may be partially oxidized and colored. There was a problem that there is.

る。Test Example 2 Next, as another test example, quartz sand that had been treated in the same manner as in Test Example 1 and untreated quartz sand were spread on petri dishes (diameter 6 cm) that had been dried and sterilized in advance. Next, ten house termite ants collected from the nest were randomly placed on the quartz sand. Next, each petri dish was placed in a container filled with water, and the containers were allowed to stand in a constant temperature room at a temperature of 28 ± 2 ° C. for 4 days. After 2 hours, 1 day, and 4 days, the health status of the termites was determined. Observed. The results are shown in Table 1 below. Comparative Example 4 shows a case where quartz sand to which no sample solution was attached was used.

It was healthy and it was found that these fatty acids had no effect as a control agent.
