Abstract: A termite extermination method of the present invention includes putting a termite extermination device 1 at a termite habitat. The termite extermination device 1 includes an exterminating agent housing 3 that is at least partially formed of a moisture-proof film 12 and houses an exterminating agent 13 in an interior of the exterminating agent housing 3. The moisture-proof film 12 includes a laminate having a paper layer and a metal layer laminated one upon another. At least the paper layer is subjected to a rugging process. The laminate is disposed in the exterminating agent housing 3 so that the paper layer serves as an outermost surface.

Abstract: A method of allowing a chemical agent to absorb into a plant body, comprising a step of obtaining a dispersion which disperses aggregates in an aqueous solvent, in which the aggregate has a particle size of 100 nm or less and comprises a chemical agent contained within an amphiphilic substance; and a step of bringing the dispersion obtained in step (1) into contact with at least part of a plant body to thereby allow the aggregates to absorb into the plant body.

Abstract: A rodent repelling method which uses smoke. The rodent repelling method of the invention is a method for repelling a rodent, which uses a smoke generated by thermal decomposition of azodicarbonamide as an active ingredient and the aforementioned smoke is diffused to a smoke quantity of 45 cpm or more.

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 1×10−3 mmHg and a boiling point of not lower than 120° C.

Abstract: A mixture of an active ingredient such as insecticide, fungicide, repellent or the like and a blowing agent is heated with a hot air current produced by a suitable heat source and a fan to thermally decompose the blowing agent and cause the hot air current and the gas resulting from the thermal decomposition to vaporize and diffuse the active ingredient. The mixture is accommodated within a passage formed in a container and the passage is provided therein with a fan for forcing the hot air current therethrough. A fumigating method and an apparatus of this invention ensure very efficient, quick and uniform diffusion of the vapor of the active ingredients and are usable for controlling vermin and other purposes with high safety and great convenience.

Abstract: A mixture of an active ingredient such as insecticide, fungicide, antiseptic or the like and a blowing agent is heated indirectly with a heat evolved by contacting an exothermic substance with water to decompose the blowing agent and to volatilize the active agent. The mixture is accommodated in at least one compartment of a container while the exothermic substance is accommodated in at least one further compartment provided with water supplying means, said compartments being separated from each other by a partition which provides a heat transferring surface.

Abstract: A mixture of an active ingredient and a blowing agent is heated indirectly with a heating element to thermally decompose the blowing agent and to volatilize the active ingredient. The mixture and the heating element are separated from each other by a partition which provides a heat transfer surface.
