Due to feral hogs’ high reproductive rates, 70 to 75 percent of the population must be killed to control the population. Louisiana reports that the hunter harvest is less than half of that objective, meaning populations are growing. Feral hogs are found in all 64 Louisiana parishes. Trapping and hunting, including day and night shooting by private landowners, plus aerial gunning by nuisance wildlife-control specialists, are used.*"
