Abstract
A fly killing composition in granular form characterized by synergistic attractant properties, an unusually long useful life, and substantial resistance to inactivation due to moisture. The composition comprises a combination base of granular, dark colored fly attractant such as fish food containing meat by-product material, in conjunction with a cooked, bright yellow, sugar-based attractant. These materials are coated with and absorb into the interstices thereof fly-toxic quantities of a mixture of 2,2-dichlorovinyl 0,0-dimethyl phosphate and 0,0-dimethyl 0-2,4,5-trichlorophenylphosphorothioate. A dusting powder applied to the insecticide impregnated particles assures that the surfaces thereof present a dull appearance notwithstanding the presence of a substantial amount of sugar in the bait formulation. The resultant fly killing composition is extremely effective in attracting flies thereto, and by virtue of the fact that the toxicants thereof are absorbed into the attractant base, the bait is not susceptible to moisture inactivation and flies alighting thereon are not repelled by the toxicant but rather are quickly killed thereby. The preferred method of use comprises spreading a thin layer of granular bait on the ground or other surface proximal to areas where flies tend to congregate, for example in dairy barns or poultry-keeping pens.
