         9 . A method of repelling a rodent, comprising:
 applying a rodent repelling composition to a surface in an area wherein rodents are to be repelled, the composition comprising 78.0 to 88.0 wt. % of a base oil selected from the group consisting of silicone oil, white oil, and combinations thereof, 5.0 to 12.0 wt. % of a thickening agent, 5.0 to 10.0 wt. % of a tackifying polymer, 0.025 to 0.10 wt. % of a repellent agent selected from the group consisting of capsaicin, piperine, allyl isothiocyanate, allicin, and combinations thereof, and 1.0 to 2.0 wt. % of a solubility improving additive, whereby rodents are repelled.
