Profiling works.

Oh yeah, this is about wild "pigs". And how we as Americans allowed the problem go until the "pigs" started causing massive damage.

Ring any bells?





Do you have any documented proof of their violent nature? (Newspaper clippings)

Ample documentation exists of wild pig-human encounters. However, the likelihood of a human being impacted by a hog/vehicle collision or disease risk—while still low is greater than an actual physical attack by a wild pig. Where the rare wild pig attack occurs, it is usually during a hunting scenario where dogs are used to bay or corner a pig in a spot and the pig “runs through” the associated hunters standing nearby. Occasionally, humans inadvertently walk between a sow and her litter and the sow reacts to protect her young. Totally unprovoked attacks outside of these two scenarios are rare. Given a choice, wild pigs usually flee rather than fight. However, U.S. newspapers report from 5 to 7 human fatalities each year.

What is the average cost of property damage they inflict in Texas? Total cost of annual property damage?

A 2004 survey conducted by Texas A&M AgriLife Extension Service placed annual damage to agriculture in TX alone at $52 million with an additional $7 million spent by landowners to attempt to control the pigs and/or correct the damage. This is indeed a very conservative estimate. Other researchers suggest that damage per pig per year averages $200– but the problem there is that the assumption is made that a 40 pound pig causes as much damage as a 300 pound pig, which is unlikely. The total pig population in Texas has been estimated recently (2011) at 2.6 million. However, estimates for the United States population as a whole are non-existent but “guesstimates” place that number between 4 million and 8 million animals. Some reports estimate total damage in the U.S. may be $1.5 billion annually—However, these damage estimates are in part based on population estimates—but again, a figure we don’t have a good handle on nationwide.

Do they use the same trails to get from pace to place? If so, why?

Wild pigs are creatures of habit and will use the same bedding/resting areas and feeding areas as long as the food source remains available. However, they are capable of moving great distances to find food. Human disturbance/pressure will make them alter their patterns of movement. They do have some affinity to their “home range” which can vary from a few hundred acres to several thousand acres based on food availability and pressure. A 2011-12 telemetry study of adult female wild pigs with sounders in east Texas resulted in home range estimates of approximately 2 square miles, or 1,100 acres.

What kind of foods are they most attracted to when trying to trap them?

One size does not fit all when it comes to baits. However, research by Dr. Tyler Campbell (formerly with USDA-APHIS/WS) suggests that wild pigs are attracted to baits that have a sweet pungent odor, such as strawberry or berry flavorings. Hence, you will see several commercial “pig baits” that contain some type of strawberry flavoring based on this research. Many baits will and have worked and landowners are encouraged to vary baits among traps to find out what pigs find most attractive at a particular location or season. However, the more abundant the food supply, the more difficult it is to attract pigs to these baits. Shelled corn is often used, but landowners have also been successful by fermenting corn, milo, rice, oats, etc. to increase the odor attraction. Old fish grease, catfish “stink” baits and overripe fruit and vegetables have also been used successfully. Others have used maple syrup on corn. Some recent research in the southeast has indicated that while catch rates were no different between shelled corn and soured corn, although we do know from experience that non-target species (e.g., raccoons, deer, crows) use of shelled corn will be much higher than a soured grain product. Please note: We do not advocate the use of diesel on corn to encourage use by wild pigs and discourage use by non-targets such as deer or raccoons because we do not know the full impacts of diesel ingestion by the pigs—some of which many be destined for human consumption. Furthermore, the pouring or contact of diesel on the ground may create an environmental hazard.

What are their eating habits, and how much they eat in a day?

Wild pigs are opportunistic omnivores, meaning they feed on plant and animal matter in addition to being able to play the role of a scavenger. They are largely indiscriminant in their feeding habits and eat both vertebrate and invertebrate animals. Approximately 85% to 90% of their diet is believed to be composed of vegetation (including crops where available) and 10% animal matter. Small pigs may eat approximately 5% of their body weight daily; larger pigs an estimated 3 % of body weight.
We seem to hear a lot of “things were fine until a year ago” remarks by people with wild pig issues.

Why the seemingly sudden boom in population and fearless invasion of residential neighborhoods?

I once made the comment that “There are but 2 kinds of landowners in Texas: Those with wild pigs and those that are about to have wild pigs”. They have steadily increased their range by moving northward and westward over the past 25 years. They have also gone from being a rural land/agriculture issue to an urban/suburban issue as well by moving into these more populated areas that are adjacent to adequate habitat that provides cover, security and food. Why the population explosion over this time? Several reasons converged to create the “perfect storm” resulting in the boom. 1) Indiscriminant stocking to new habitats by landowners and hunters facilitated rapid increase—pigs cannot fly but they can be trailered and released. This was done regularly (–DESPITE BEING ILLEGAL) in the 1970’s thru the 1990’s—and the stockings were very successful at re-establishing wild pig populations across the state. 2) Supplementing non-migratory wildlife (deer, turkeys quail etc.) is legal in the state of Texas. For example, an estimated 300 million pounds of shelled corn are fed to deer annually in Texas, along with at least 120,000 million pounds of “protein pellets”. However, non-target species (e.g., wild pigs, raccoons) get their fair share of these supplements. As a result, the sows that are on this higher nutritional plane because of their access to the unintended supplement allows sows to undergo “flushing” : produce more eggs, have larger litters and have more pigs in their litters survive. 3) Wild pigs are the most prolific large mammal on the face of the earth. They are not “born pregnant”, but their high intrinsic (built-in) rate of increase when environmental conditions are favorable can allow for rapid population increases. Population increases are not just a Texas phenomenon—for various reasons, populations have expanded in many states and now some 36 states have established wild pig populations.

What’s the difference between a pig, hog and a boar, and are their different species?

All are descendants of a common ancestor-the Eurasian wild boar. The term Wild boar is typically used to describe Eurasian wild boar from Europe or Asia. Feral hogs are those that originated from domestic breeds but may be the result of a few or many, many generations in the wild. In the U.S., the best descriptor is probably to refer to them simply as wild pigs. Regardless, the Eurasians and domestics gone feral are largely the same species and therefore will interbreed with no problems resulting in all sorts of “hybrids” between the 2 groups. None of these should be confused with the javelina, a native pig-like mammal found in the American southwest that is not even closely related to wild boars/wild pigs/feral hogs. The best name to use is simply “wild pig”.
