In recent years, a need for effective ways to exterminate Nutria from regions such as Luisiana marshes has arisen. The most simple method of killing them is through the use of traps. To improve the effectiveness of traps, Susan Jojola, Gary Witmer, and Patrick Burke researched how the use of attractants improved the chances of capturing a nutria. After a controlled study of 14 different possible lures in both a lab setting and in nature, the researchers concluded that a synthetic nutria fur and anal-gland extract was the best formula to attract the animals. The final chemical developed increased the chance of capture by around two and a half times. The use of attractants like the one created was suggested to be used as a cost-effective method to reduce nutria damage.
