"If pigs are so hard to catch, how did they vaccinate all those wild ones to eradicate a disease?"
There's no way you could catch all the feral pigs and vaccinate them. Where did get that information? That's would be like trying to sterilize all the male feral pigs. They did wipe out all the screw worms in Texas by dropping sterilized male flies from airplanes all over Texas. It's hard to believe that worked.
I was around when they did that. Found the little boxes the flies were dropped in, all over the ranch.
Screworms were a major issue to ranchers and livestock. Doctored many, many cattle for them. Lost a few calves too.
That program wiped out screworms, and the deer population explosion was a byproduct of it.
If the deer benefited massively, you know the feral hogs did too.
