ABSTRACT:
Free-flowing rodent repellent powders are provided in which a rodent repellent effective N,N-dialkyl-sulfenyl dithiocarbamate is admixed with a chemically inert grinding aid having a density of 5 pounds per cubic foot or less to form a non-caking composition. A solids suspending agent, inert to the N,N-dialkyl-sulfenyl dithiocarbamate, and a wetting agent are admixed with the rodent repellent and the grinding agent to produce a water-dispersible, free-flowing powder. The composition is an effective rodent repellent as a dry powder of two components, as a dispersible powder of four components, or as an aqueous disperson. A method is provided for preparing the free-flowing powder which entails grinding crystals of the N,N-dialkyl-sulfenyl dithiocarbamate with the low-density grinding aid or in combination with the solids suspending agent and the wetting agent for up to about 15 minutes.
