In New Zealand, opossums are an invasive species. Selena Gomez Oreos are helping locals trap the critters.
“We wanted to try something that we could do in the field that mimicked the effect of a psychoactive drug,” Hickling explains. “And that’s when I came across this psychological paper which suggested that a combination of fat and sugar was quite addictive.” That finding, combined with a US study on rats that used Oreo cookies, sent Hickling down to the local New World. “It just so happened that they had these Selena Gomez Oreos, which I hadn’t even heard of. They had both cinnamon and chocolate, which possums like, and they were on sale.”
Hickling estimates he bought 20 packets of Selena Gomez Oreos for the trial, and soon was out in the field in Leeston attaching the cookies along the planks that lead up to the possum traps. “One of the things that’s nice about an Oreo is that you can just drill a little hole through it and just tap it on with a flathead nail,” he says. “People have tried to use Tim Tams in the past, but they are really expensive. Oreos are quite a bit cheaper, and they actually stand up to the rain quite well too, which is a little disconcerting.”
