A water soluble rodent repellent composition which can be coated onto a material, e.g., a cable, which is laid into the ground. Ground moisture dissolves the composition, forming in the earth surrounding the cable a rodent repellent barrier thus preventing contact of the rodent with the cable or material. Any rodent repellent in a water soluble or water dispersible composition can be used. Specifically mentioned in the disclosure as now preferred effective rodent repellents are N,N-dialkyl sulfenyl dithiocarbamates, e.g., the N,N-dimethylsulfenyl dithiocarbamates, N,N-dimethyl-S-methylsulfenyl dithiocarbamate and N,N-dimethyl-S-tert-butylsulfenyl dithiocarbamate. The repellent is combined with dimethylsulfoxide and polyvinylalcohol or it is combined with one of dimethylsulfoxide and dimethylformamide, and with a hydroxyalkyl cellulose, e.g., hydroxypropylmethyl cellulose.
A composition suitable for application to an object subject to rodent damage by chewing by the rodent of the object to protect said object against such damage by keeping the rodent at a distance from said object when it is buried in the ground and which upon application to said object forms thereon a solid, moisture dispersible layer which comprises in a non-aqueous, liquid solvent, a solid, water-soluble, repellent holding dispersible carrier and an effective N,N-dialkylsulfenyl dithiocarbamate rodent repellent, the rodent repellent being present from about 1-45 weight percent of the composition, the remainder of the composition consisting of said carrier and a solvent, said carrier being present in preponderance in said remainder of the composition, said non-aqueous liquid solvent being selected from the group of dimethylformamide and dimethylsulfoxide and mixtures thereof and said solid, water-soluble carrier being a hydroxylalkyl cellulose, said composition being adapted upon being acted upon by moisture in the ground to release a rodent repellent protective barrier surrounding said object.
