In a breakthrough response to the escalating feral hog crisis, Louisiana State University’s AgCenter and Department of Chemistry have patented a novel bait, laced with sodium nitrate, that promises to bring the rampant hog populations under control. This innovation comes after years of rigorous research, spurred by the escalating damage to Louisiana’s agricultural sector, which sees approximately $91 million in losses annually due to these invasive animals.

The feral hog population, currently estimated at a staggering 1 million in Louisiana alone, has doubled in the past decade. These creatures, notorious for ravaging fields in search of food, have proven challenging to control due to their rapid reproductive rate and group behavior. The introduction of the sodium nitrate bait, a solution painstakingly developed over several years, presents a significant milestone in the fight against this ecological menace.

Louisiana State University Develops Innovative Solution to Feral Hog Problem

Louisiana has been grappling with a feral hog problem for years, as the rapidly proliferating species has wreaked havoc on the state’s crops, causing an estimated $91 million in damages annually. However, thanks to the dedicated efforts of scientists at the Louisiana State University’s AgCenter and Department of Chemistry, a novel solution has been patented – a bait using sodium nitrate.

Exploding Hog Populations

The feral hog population has doubled in Louisiana over the past decade, with current estimates placing their numbers at around 1 million. These creatures, which travel in packs, are notorious for uprooting fields while in search of food. The escalating damage necessitated a solution, prompting scientists to begin researching and developing effective control options.

An Innovative Approach: Sodium Nitrate Bait

The patented bait, which has been under development for several years, is shaped like gummy bears and has a fishy flavor. This innovative solution even glows under backlights, enabling easy retrieval of any leftovers. According to the scientists involved in the project, hogs become sleepy and die within three hours of consuming the bait.

Glen Gentry, one of the patented inventors and an animal scientist and director at LSU AgCenter, emphasized the suitability of sodium nitrate as a toxicant. The substance is lethal to swine but decomposes into compounds that are harmless to other species and the environment.

Fine-Tuning the Solution

Achieving this breakthrough wasn’t easy. Gentry and his team experimented with various ingredients to lure the hogs before settling on dehydrated fish. The bait’s gummy-like texture ensures it doesn’t disintegrate when bitten, minimizing leftovers and ensuring the target species are affected.

Field trials are currently in progress to determine the product’s shelf life and the optimal delivery methods before the bait can be approved by the Environmental Protection Agency (EPA) and made available to the public.

Other inventors credited on the patent include Bob R. Jones-Idlewild Research Station in Clinton, John Pojman, an LSU chemistry professor, and Baylen Thompson, a former graduate student who worked under Pojman.


This innovative solution from LSU scientists could be a game-changer in controlling feral hog populations, not only in Louisiana but potentially in other areas struggling with similar challenges. It’s a testament to the power of scientific research in addressing real-world problems. However, field trials and EPA approval will be crucial next steps before this product can hit the market.
