Abstract

Provided is a technique comprising blowing air onto a carrier having supported thereon a preparation containing a highly safe pesticidal component to vaporize and diffuse the component from the preparation under non-heating conditions thereby to control flying insect pests. An insect pest control method characterized by preparing a preparation-retaining material by supporting on a carrier a preparation containing a pesticidal component which is hard to vaporize at normal temperature, preferably at least one pesticidal component selected from compounds which are hard to vaporize at normal temperature and have a vapor pressure of lower than 1.times.10.sup.-3 mmHg and a boiling point of not lower than 120.degree. C./1 mmHg, setting the resulting preparation-retaining material, and contacting the preparation with an air current raised by an air blowing means to release the component into the air under non-heating conditions, an apparatus suitable therefor, and a carrier to be used in the preparation-retaining material set in the apparatus characterized by not blocking the air current toward the vent hole of the apparatus are provided.
