To suppress adverse effects and simply remove a wide range of allergens such as a mite, a Japanese cedar pollen or a cockroach at a low cost without leaving toxic substances in an environment in order to suppress the onset of allergy by denaturing the allergens utilizing an organic solvent such as an alcohol and inactivating the allergens.
An organic solvent such as an alcohol (preferably the alcohols such as ethanol, methanol or propanol, hydrocarbons such as hexane, toluene or xylene or halogenated hydrocarbons, etc., such as chloroform or dichlorobenzene) is brought into contact with allergens by spraying such as an aerosol to thereby denature and inactivate the allergens and remove the allergens. Ethanol at 20-100 vol./vol.% concentration is more preferably utilized as the organic solvent.
