American people see wild pigs in three quarters of the state. Their numbers are growing rapidly in many areas. AP reported that they caused economic losses of $ 1.5 billion per year. According to the US Department of Agriculture statistics, more than 5 million wild pigs live in the states.

Pigs are smart animals, but quite aggressive for humans and pets. They can cause many threats to nature, such as eating endangered animals or spreading invasive grasses. In addition, wild pigs can transmit more than 30 diseases to humans, cattle and other wildlife. Their habit of digging soil and eating their roots reduces the productivity of crops in the farm. The holes that wild boars create on the road can cause unexpected traffic accidents.

New Mexico state authorities recently spent $ 1 million to create programs to hunt, trap and kill wild pigs. Officials want to combine many measures, because wild boars are so smart that they always learn from the experience after every death.

'Wild pigs are far smarter than my thoughts. If their limbs are as clever as human hands, I think they can drive cars , 'said Ray Powell, a state veterinary veteran.

Hunters also adopt the strategy of 'antagonist pig' . After destroying a herd of pigs, they deliberately let one female pig survive and attach a ring to her neck. Thanks to the tracking device on the ring, hunters can detect the location of other herds and kill them.

The number of wild pigs reached the highest level in Texas. So the experts predict the problems that wild pigs cause in Texas will get worse in the future, despite the state government spending $ 7 million per year to control the reproduction of pigs. A recent study by the University of Texas Agricultural and Mechanical University showed that the number of wild pigs will triple in the next five years if the government does not adopt strong measures.

High fertility is the main factor that helps wild pigs thrive. After 6 months of birth, female pigs were able to become pregnant. They produce an average of 6 animals per litter and each year they average 1.5 litters.

Spaniards brought wild pigs to North America in the 16th century to serve hunting. In a wild environment, the weight of pigs can reach 136kg or more.
