<p>The formulation of improved fly attractants is disclosed that is effective to attract both the house fly and the blow fly. The attractant is placed in fly traps designed to prevent a fly from leaving the trap after it has been drawn into the trap by the attractant. The flies in the trap may be killed either by excess water in the trap to drown them or by an appropriate insecticide. The inclusion of sodium bicarbonate in fly attractants increases the effectiveness of the fly attractant from about four to about ten times. The most preferred formulation consists of about 60 % by weight powdered egg, about 25 % yeast and about 15 % sodium bicarbonate diluted by about 50 parts by weight of water.</p> |
