Abstract
A rodenticide is disclosed comprising an encapsulated zinc phosphide toxicant, a bait, and a binder for adhering the encapsulated zinc phosphide to the bait, said binder comprising a polyol or a sugar-containing fluid. The encapsulant is a thermoplastic polyamide, preferably nylon, present in an amount of from about 2% to about 10% by weight of zinc phosphide. When the bait is a grain or a processed grain, a zinc salt is preferably added to the rodenticide to inhibit the generation of phosphine. Histamine, a histamine salt or a histamine-producing substance, such as red pepper, can also be added to the rodenticide to stimulate acid secretion in the stomach of the rodent. A particulate encapsulated product is also disclosed comprising a core of zinc phosphide having a coating of a thermoplastic polyamide present in the range of from about 2% to about 10% by weight. The encapsualted product is a small particle capable of passing through a 40 mesh size screen.
