Absorbent cotton soaked in 3% sugar water was placed inside the tube (0 ts).

In order to keep the temperature inside the glass tube containing the above composition constant and the temperature inside the desiccator, a PVC tube was wrapped around the desiccator and the glass tube, and hot water was poured into the PVC tube.

The test time was from approximately 5:00 pm to 8:00 the next morning, and the number of individuals present in the desiccator and release cage and their blood-sucking rate were investigated, as well as the number of dead (or knocked down) individuals. 11. After the Culex mosquito was expelled, the laboratory room was kept in darkness. The results obtained are shown in Table 2 below.

<Effects> As described above, the present invention uses a mixture of two or more different high vapor pressure pest control components, and therefore has the excellent feature of synergistically improving the pest control effect.
