Outside/In

Last spring, a curious listener called with an unusual question about coyote urine. Is it – as advertised by companies who sell it – an effective, all natural pest deterrent? And more importantly: “Who are the coyotes that are providing this urine?”

Since then, producer Taylor Quimby has been trying to find out… and with literal gallons of the stuff available online, he discovered the answers aren’t pretty.

Today on Outside/In, we peek inside the unregulated Pandora’s box of urine farming. Does it work? Is it ethical? And is anybody willing to actually talk about it?

Featuring Jeannie Bartlett, Caroline Long, Ed Brookmyer, Laura Koivula.

This episode was first published in August 2025.

This 1998 study assessed coyote urine as a deterrent for deer, and found (with some caveats) a 15-24% reduction in deer browsing after exposure to the urine.

However, coyote urine had no measurable effect on the deer browsing of yew saplings in this more recent study.

Websites for some coyote urine brands, like PredatorPee.com and Shake-away animal repellents, claim that they source urine from regulated farms that treat animals humanely, but did not provide more information when asked.

This article from Cleveland.com details the conditions at The Grand River Fur Exchange, a fur and urine farm where hundreds of animals were found in poor condition after the owner’s death.

Since we reported this story, Ohio lawmakers have introduced a bill in response to what was discovered at the Grand River Fur Exchange. If passed, the bill would require much stricter oversight for commercial breeding facilities in the state.

Maui has a problem: too many deer, not enough hunters. So on a dark, humid night, Nate joined a group of elite hunters as they endeavor to turn an ecological nightmare into a source of profitable, high-protein venison.

Over the course of a few hours, he watches the employees of Maui Nui Venison methodically shoot dozens of deer, collect their carcasses, and speed them to a mobile slaughterhouse for processing – all under the watchful eyes of the USDA.

Can you bring the efficiency of the slaughterhouse to the natural world? And is commercial hunting a solution for America’s over-abundance of deer?

A University of Wisconsin professor outlined how commercial hunting would work in the U.S. in a 2011 paper.
