A blower type chemical diffusing apparatus is small in thickness, simple in structure, and reduced in cost. The apparatus allows the chemical and a battery to be exchanged readily and facilitates electrically connecting the battery to the motor in the blower. The apparatus casing includes a first and a second side casing counterpart hinged together to allow opening and closing. The apparatus further includes a blower with a motor and fan mounted in the first casing body. A chemical cartridge is disposed between the blower and the second casing body, and contains a chemical impregnated body which includes a carrier in the form of a sheet impregnated with the chemical. The first casing body has a battery accommodating recess in which dry cells are removably accepted to drive the motor and thereby to rotate the fan. Air is thus forced to flow through the chemical cartridge.

Blower type chemical diffusing apparatus, and chemical cartridge and chemical impregnated body used therefor

A chemical cartridge for a blower-type chemical diffusing apparatus includes a chemical-impregnated body including an air-permeable and liquid-absorptive sheet impregnated with a chemical, and a retainer receptacle for containing the chemical-impregnated body. The retainer receptacle includes a liquid pool recess formed at a central area thereof such that liquid chemical stored in the liquid pool recess is permeable towards a peripheral area of the sheet.

A blower type chemical diffusing apparatus is disclosed which can be of service for an extended period of time and does not give rise to refuse disposal problems. The blower type chemical diffusing apparatus of the invention has an air blower, a chemical retainer and a fuel cell included in the apparatus body whereby powering the air blower to drive it with the fuel cell causes chemical from the chemical retainer to be emitted into an environmental atmosphere.

A heat fumigation apparatus for transpiring a solution of a chemical agent dissolved in a solvent by heating which comprises a container having the solution therein, a wick a part of which is immersed in the solution and a heater for heating the upper portion of the wick thereby transpiring the solution drawn up the wick. The wick is composed of an inorganic powder and/or an organic powder, a binding agent and at least one antioxidant which is substantially non-evaporative at a heating temperature.

Heat fumigation apparatus

An insecticidal composition for electric fumigator consisting essentially of:

Insecticidal article for electric fumigator

In a method for knock down of injurious insects or for freeing a particular environment therefrom by heating fumigation comprising dipping a part of a porous absorptive wick in an insecticidal solution to allow it to absorb the solution and indirectly heating said wick around the top to fumigate the absorbed insecticidal solution, a method for knock down of injurious insects or for freeing a particular environment therefrom, which comprises exposing the insects to the vapor, characterized in that a C.sub.12 -C.sub.18 aliphatic saturated hydrocarbon solution containing as an active ingredient 2-methyl-4-oxo-3-(2-propynyl)cyclopent-2-enyl chrysanthemate is used as said insecticidal solution, a porous absorptive wick prepared by caking a powdery inorganic substance with a binding agent is used as said porous absorptive wick, and besides that said absorptive wick is indirectly heated around the top to a temperature in a range of from 105.degree. to 130.degree. C.

Method for killing insects by heating fumigation

A thermoevaporative insecticidal apparatus comprises a heat generating element 1 closely fitted to a porous carrier 6 the surface of which is impregnated with an effective ingredient and a receptacle 7 composed of a receiving tray 8 on which a plurality of supporting stands are disposed said heat generating element 1 being supported on the receptacle 7 so that said porous carrier 6 faces down opposite the receiving tray 8 and that said tray 8 is spaced from said porous carrier 6 by a distance of at least 1 cm; and

Thermoevaporative insecticidal apparatus and a container assembly used

A method of enhancing the activity of a fast evaporating insecticide characterized by incorporating in a pyrethroid insecticide one or more compounds selected from the group consisting of a phthalic ester, aliphatic ester, aliphatic dibasic ester, aromatic carboxylic ester, higher aliphatic alcohol, polyhydric alcohol, glycol ether and a hydrocarbon having 10 or more carbon atoms and one or more antioxidants.
