Abstract
Abstract Stable oil-in-water emulsions of N,N-dimethyl sulfenyl dithiocarbamates rodent repellents, with asphalt and polyolefins, are prepared using emulsifying agents selected from certain amphoteric, nonionic, and anionic emulsifiers, which emulsions can be readily applied to surfaces to render same rodent and roach repellent.
