Procedimiento para repeler o eliminar organismos nocivos

摘要

A method for repelling and eliminating a harmful organism comprises emitting in the air a chemical liquid containing an effective ingredient as atomised chemical particles. The atomised chemical liquid is sprayed intermittently and in such a manner as to have a particle size distribution of the resulting atomised chemical liquid fine particles in which 90% by cumulative volume of the chemical liquid fine particles based on volume cumulative distribution has a particle size of 20 mu m or less. The method reduces the energy required to release the chemical liquid and improves the safety and stability of the atomized liquid.
