Mice invading your RV? Lion poop to the rescue

Through the years, we’ve written about a dozen ways to keep mice, squirrels and other rodents out of your RV. Some probably work, some probably don’t. Nobody seems to agree on the absolute best way.

Well, could this be it? There’s one way to keep these pests (and even bigger ones like possums and bears) away from your RV according to an RVer named Jeff Schwartz, who outlined his method in a comment to our YouTube video “How to keep mice out of your RV.” We doubt you have heard of this technique before. Here, shortened for brevity, is what Schwartz wrote:

There is one known foolproof, usually free, way to keep all animals (mice, cats, dogs, possums, bears, etc.) away from your home or RV! Go to your local zoo and ask for some lion or tiger poop and line your property with it. Zoos will usually give you all you want. It works every time. Carry it home in garbage bags.

Just spread it lightly where you do not want animals to go and they will all stay away forever. I have seen neighborhood dogs (several times) walk around my property. They will no longer cross a line of lion poop that I laid out about a month ago. Best of all there is absolutely no smell for humans!

I didn’t believe it until I saw it work—100 percent of the time. Try it—you will be amazed. I even tested it with cockroaches and they turned around when they came to the line of poop. Nothing alive will cross that line!

But be careful if you have pets. My dog will no longer get into my Blazer because I spilled the lion poop in the very back about six months ago. (I have since had the interior cleaned.) My dog still will not come close to my car.

Editor’s note: If you do not wish to track down a friendly lion trainer at your zoo, you can purchase urine at Amazon from foxes, mountain lions and coyotes, which is supposed to do the same thing as what Schwartz suggests (although we’ll guess that it won’t keep a bear away!).

I tried the fox urine in my back yard to keep the rabbits off the grass…didn’t work. And since they share the desert all around me with coyotes that wouldn’t work either. I thought my dog would keep the rabbits away but I think he plays with them!

Sounds like Schwartz is a master practical joker trying to see how many people he can convince to run to the zoo to pick up lion poop!

I agree with Tommy! I want them DEAD! None of these “tricks” will keep mice out.

I just caution against poisons if you have dogs or cats or are in a neighborhood where others’ pets could get hold of a poisoned rodent. Most of these poisons are neurologics and the effects cannot be reversed like the old anti-coagulant poisons.

I never understand those who want to scare the mice away. I want to see them dead, and dead NOW, not later. It’s not like we’re dealing with an endangered species here. It’s war, and if you don’t address the problem as “war” you can forget about winning!

There’s a channel on YouTube called “Mouse Trap Monday” that debunks nearly every mouse deterrent available. The results are always the same. If there’s food, the mice will overcome their fear. Not saying Lion poop doesn’t work. Just skeptical after watching so many failed tests. Still I am curious if this is the exception. Sent an email to the channel author asking him to test it out.

I just returned from a month long African safari, Uganda, Kenya and Tanzania. We saw lions everywhere. Dang, If I had only known to bring my pooper scooper. Plus going through customs would have been interesting, ha.

What if the mouse has never experienced a lion and doesn’t know that it’ll be like popcorn chicken to the lion if it comes around? Lol

Many animal species have genetic memory of threats that they inherit. For example, some monkey species are terrified of snakes the first time they see one.
