A method for repelling pests, comprising applying a pest repellent onto a skin surface of a human such that an amount of a liquid oily component is 0.1 mg or more per 1 cm2, wherein the pest repellent comprises, as an active ingredient, at least one liquid oily component selected from the group consisting of a silicone oil, an ester oil, an ether oil, a hydrocarbon oil, an aliphatic higher alcohol having 14 or more carbon atoms, and a polyhydric alcohol, the liquid oily component having a surface tension at 25° C. of 40 mN/m or less and a viscosity at 23° C. as measured with a B-type rotational viscometer of 1,200 mPa·s or less.
