I hate to see animals that are the source for food killed by the use of poison. However, I certainly understand the land owners position due to the amount of damage wild hogs can and will do. It has come to this because hunting by hunters and damage control people during the day and night and from aircraft has not been able to reduce the hog population to a point where the amount of damage done by them is negligible and or acceptable. I don't know enough about Warfarin to know if secondary poisoning could be a problem with scavengers. I would assume there are some regulation regarding cleaning up the carcasses.
