Test Example 1 Test Method (Blowing Condition) The composition (diameter 5.5 cm, thickness 0.5 cm) obtained in Example 21 was placed in a glass tube (inner diameter 45 mm, length 500 mm), and the amount of air flowing in
The volatile component of the above composition was sent into a desiccator (capacity: about 10) by blowing air at 0.4 / min. Note that absorbent cotton was stuck to the inner wall surface of the desiccator.

A mouse (fixed in a wire mesh) is placed in the desiccator as a blood-sucking source, and a Culex pipiens cage consisting of a vinyl insect repellent net connected to the desiccator by a communication passage with an inner diameter of 32 mm (height 20 cm, width 20 cm, depth 30 cm) Within 3%
Absorbent cotton soaked in sugar water was added.

Further, in order to keep the temperature in the glass tube containing the above composition and the temperature in the desiccator constant, a PVC tube was wound around the desiccator and the glass tube, and hot water was allowed to flow through the PVC tube.

At approximately 5:00 pm to 8:00 am the next morning, the number of individuals present in the desiccator and the expulsion gauge and their blood absorption and the number of dead (or knocked down) individuals were examined. The test room was kept in a dark state after the release of Culex pipiens. The results obtained are shown in Table 2 below.

<Effect> Since the present invention uses a mixture of two or more different high-vapor-pressure pest control components as described above, it has an excellent feature of synergistically improving the pest control effect.
