1. A method for killing a feral hog, comprising feeding the hog a composition, in an amount sufficient to supply a lethal dose of sodium nitrite to the hog; wherein the composition comprises a mixture of:
(a) a food that is acceptable to feral hogs;
(b) sodium nitrite, wherein the sodium nitrite is not microencapsulated; and
(c) a base selected from the group consisting of sodium carbonate, sodium bicarbonate, calcium carbonate, magnesium hydroxide, magnesium carbonate, potassium carbonate, potassium bicarbonate, egg white albumin, and an amine; wherein the concentration of the base imparts a pH between 8 and 11 to the mixture;
wherein the composition is supplied as a bolus or boluses, comprising at least 2.0 gram sodium nitrite per bolus;
wherein the pH of the composition inhibits the decomposition of the sodium nitrite, such that when the composition is placed outdoors in a field or in a bait station under ambient conditions, any decomposition of the sodium nitrite is sufficiently slow that the composition does not become aversive to hogs for at least seven days; and
wherein, for at least seven days, when placed outdoors under ambient conditions, the composition remains acceptable to feral hogs.
