seabast,
I think Texas' problems isn't the fact they don't understand how to hunt them. This article (it is older mind you) really gives a closer look at the problem:

Texas right now has open season on hogs and zero limit. Texans can also trap them and ship them to a state slaughterhouse for selling as an exotic meat. They can be shot en mass from a helicopter. I don't think the problem is how to hunt them. This animal is versatile in it's menu and habitat. It affects it's environment on a macro scale. It breeds like a rabbit. When fully grown it doesn't have any natural predators in Texas as it has amble means to defend itself (and sows will defend their young) if necessary. They are mainly nocturnal and can be as fast as a rabbit (boar and rabbit are approximately 30 mph) in bursts. Add into the equation that the states which neighbor Texas may not have as liberal rules when it comes to hog hunting and those hog will "reinforce" the Texas population. Moreso, some landowners are trying to make a dollar off hog hunting (kind of like some reports of landowners crying the elk are destroying their property in Bancroft but wanting to charge hunters to come onto their land to hunt) which means hunters will probably only hunt a few hogs.
I think what needs to happen is Texas and its neighbours need to come up with a plan much like Australia has for it's kangaroo problem. In Australia, there are government licensed hunters who get paid to shoot kangaroos (many do it as a side job) coupled with the fact that Australians can hunt kangaroos recreationally as well is a solid start to manage a population which is way out of control. Allow the professional hunters to bring their carcasses into the state approved slaughterhouses for export (as the professionals in Australia are allowed to do). Allow spotlighting and night shooting by the professionals (and only the professionals) for these animals. Have the professional hunters mainly target the sows and piglets (boars could be on a quota system) to reduce the breeding and feeding population as fast as possible as they are the ones who group up the most.
