Toxicants
There has been lots of talk in recent years about the use of toxicants for wild hog control efforts. Several toxicants have been used in Australia such as sodium nitrite, yellow phosphorous, and compound 1080 (sodium flouroacetate), but none of these toxicants have been approved for use in the United States.
Ongoing research is being performed by various state, federal, and private agencies to devise a way to safely and selectively administer this toxin to wild-living swine populations, but there are no lawful means of wild hog control with the use of any type of toxicant or poison at this time. Remember, it is illegal to distribute any type of toxin, poison, or other harmful substance on your land for the use of wild hog control.
