In a significant breakthrough following years of dedicated research into managing escalating feral hog populations, LSU AgCenter scientists in collaboration with the LSU Department of Chemistry have successfully developed a game-changing solution. This groundbreaking bait, now patented, offers a promising method to curb the explosion of feral hogs that have been causing substantial economic and environmental damage, says the release.
Sodium Nitrite-based Bait for Humane Feral Hog Control
This revolutionary bait leverages the power of sodium nitrite to effectively address the issue of feral swine, which have been responsible for causing millions of dollars’ worth of destruction to agricultural fields and forestlands not only in Louisiana but across the nation, the release explains.
Shaped into conveniently-sized spheres similar to gummy bears and possessing a distinct fishy flavor, this bait is a testament to the collaborative efforts of the LSU AgCenter’s animal scientist and director of the Bob R. Jones-Idlewild Research Station in Clinton, Glen Gentry; LSU chemistry professor John Pojman; and former graduate student Baylen Thompson, who worked under Pojman’s guidance.
Gentry expressed his enthusiasm, calling the patent issuance on Aug. 8 a significant milestone, in the release. Years of dedication have culminated in this innovative solution, developed in response to the burgeoning challenges posed by feral hogs in rural areas.
Addressing the Feral Hog Challenge: A Growing Problem
The rapid proliferation of feral hogs in recent years has posed a formidable challenge, with Louisiana alone witnessing a doubling of the feral hog population over the last decade, estimated at approximately 1 million. Traveling in packs and notorious for their foraging habits that wreak havoc on fields, these creatures are estimated by AgCenter experts to inflict around $91 million in annual damages within the state, says the release.
The highly prolific reproductive rate of these hogs has complicated population control efforts. With sows capable of birthing two litters of approximately six piglets each year, traditional control methods like hunting and trapping have proven insufficient to keep their numbers in check.
Gentry highlighted the bait’s effectiveness as a humane solution to the feral hog problem. Upon consuming the bait, hogs experience drowsiness and eventually die within a mere three-hour timeframe.
Sodium nitrite was identified as the ideal toxicant due to its lethal impact on swine while eventually breaking down into harmless compounds that do not endanger other species or the environment, the release explains.
Pojman’s involvement and his team’s pH adjustments to stabilize the sodium nitrite proved crucial. This strategic alteration slows the conversion of sodium nitrite into nonlethal compounds, ensuring hogs have ample time to consume the bait.
Developing a bait that effectively attracted feral hogs took numerous iterations over the years. Gentry and his team experimented with various ingredients before discovering the winning formula: dehydrated fish.
The bait’s rubbery texture is pivotal in preventing disintegration upon biting, curbing litter on the ground and safeguarding non-target species. Additionally, the inclusion of fluorescence in the matrix enables easy detection of any remnants by utilizing a blacklight.
The researchers are now directing their efforts toward additional field trials and studies to assess the bait’s shelf life. Furthermore, they are actively exploring optimal delivery methods, considering options such as burying the bait for rooting hogs or utilizing a feeder mechanism triggered by a cellphone.
However, before the bait can be introduced to the public, it needs approval from the EPA, necessitating adherence to a stringent set of requirements.
The release notes, this groundbreaking research wouldn’t have been possible without the support of stakeholders who provided essential funding, including the Irene W. and C.B. Pennington Foundation, the Bob R. Jones Wildlife Research Institute, the Louisiana Soybean and Grain Research and Promotion Board, the Louisiana Rice Research and Promotion Board, the Louisiana Legislature and the Louisiana Department of Wildlife and Fisheries.
