Fast-kill drenches of Sevin 80WP, Dursban 4E and Spectracide 2E provided ca. 80 - 90% control of treated colonies for 112 days. The Orthene 75S dust application was as effective as the drenches and easier to use. Leaded gasoline was the only home remedy tested which provided adequate control; ca. 90% control for 42 days posttreatment. However, it is an illegal application as law specifically restricts its application to soil. Of the slow-kill insecticides, Affirm W002 gave better control of singly treated RIFA colonies over a longer period than did Amdro. Colony relocation after treatment was a problem frequently encountered; the mound fumigant Cleanite caused the highest incidence of colony movement.
