What Keeps Mountain Lions Away? A Comprehensive Guide to Deterrence
What keeps mountain lions away? Effective deterrence hinges on consistently removing attractants, maintaining vigilance, and employing a multi-pronged approach combining physical barriers, noise deterrents, and modified human behavior to discourage mountain lions from approaching homes and settlements.
Understanding Mountain Lion Behavior and Habitat
Mountain lions, also known as cougars or pumas, are apex predators that inhabit a wide range of environments across North and South America. Their solitary nature and preference for elusive hunting make them a significant concern for people living in or near their habitat. Understanding their behavior is the first step in understanding what keeps mountain lions away. They are crepuscular, most active at dawn and dusk, and prey primarily on deer but will also take smaller mammals, livestock, and pets. Their territorial range can be quite large, depending on the availability of prey and suitable habitat.

The Key to Deterrence: Eliminating Attractants
One of the most crucial aspects of preventing encounters with mountain lions is to eliminate attractants that might lure them closer to human settlements. These attractants often involve food sources, but can also include shelter or easy access routes.
-
Food Sources:
- Pet food left outdoors. Bring pet food indoors, especially at night.
- Unsecured garbage. Use bear-resistant garbage containers or store garbage inside a secure building until collection day.
- Bird feeders. While seemingly innocuous, bird feeders attract rodents, which in turn can attract mountain lions. Consider removing them or suspending them in a way that prevents rodents from accessing them.
- Fruit trees. Fallen fruit attracts deer, which, again, will attract mountain lions. Clean up fallen fruit regularly.
- Unprotected livestock. Securing livestock, especially at night, is critical. Use barns, pens, or guard animals.
-
Shelter:
- Dense vegetation close to the house. Trim back shrubs and trees near your home to eliminate hiding places for mountain lions.
- Unused sheds or outbuildings. Ensure that outbuildings are secured to prevent animals from using them as shelter.
Creating a Protective Barrier
Physical barriers can be effective in deterring mountain lions, especially when combined with other preventative measures.
- Fencing: A high, sturdy fence (at least 8 feet tall) can deter mountain lions, particularly if the bottom is buried to prevent them from digging under. A fence angled outward at the top can also make it harder for mountain lions to climb. Electric fencing can provide an extra layer of protection.
- Lighting: Motion-activated lights can startle mountain lions and deter them from approaching.
Using Noise and Other Deterrents
Auditory and visual deterrents can disrupt mountain lion behavior and make them less likely to approach.
- Noise Makers: Air horns, whistles, and even loud shouting can scare away mountain lions. Carry a noise maker when hiking or walking in mountain lion territory.
- Sprinklers: Motion-activated sprinklers can startle animals and deter them from entering your property.
- Guard Animals: Dogs and livestock guardian animals (LGAs) can effectively protect livestock and property. Choose breeds known for their protective instincts and train them properly.
Modifying Human Behavior
Our behavior plays a crucial role in preventing encounters with mountain lions. Being aware of your surroundings and taking precautions can significantly reduce the risk.
- Supervise Children and Pets: Keep children and pets indoors, especially at dawn and dusk. If you must be outside, keep them close and supervise them closely.
- Hike in Groups: Mountain lions are less likely to approach groups of people.
- Make Noise While Hiking: Announce your presence by talking loudly, singing, or carrying a bell.
- Be Aware of Your Surroundings: Pay attention to signs of mountain lion activity, such as tracks or scat.
- Know What to Do if You Encounter a Mountain Lion: Stand tall, make yourself look larger, and make noise. Never run. Back away slowly while maintaining eye contact. If attacked, fight back aggressively.
When Deterrence Fails: Reporting Sightings
If you observe a mountain lion in an urban or suburban area, or if you believe a mountain lion poses an immediate threat, contact your local wildlife agency or law enforcement. Reporting sightings can help wildlife officials track mountain lion populations and implement appropriate management strategies.

Frequently Asked Questions
What is the best way to deter a mountain lion from my property?
The most effective approach involves a combination of strategies. Remove attractants like pet food and unsecured garbage, install motion-activated lights, consider fencing, and be vigilant about supervising children and pets. A multi-pronged approach is far more likely to be successful than relying on a single method.
How high should a fence be to keep out mountain lions?
A fence should be at least 8 feet tall to effectively deter mountain lions. It’s also beneficial to bury the bottom of the fence to prevent digging and to angle the top outward. Electric fencing adds an extra layer of security.
Are dogs effective at keeping mountain lions away?
Dogs can be effective deterrents, particularly larger breeds with strong guarding instincts. However, dogs must be properly trained and supervised to avoid becoming prey themselves. Livestock guardian animals (LGAs) are often specifically bred and trained for this purpose.
What should I do if I encounter a mountain lion while hiking?
Stay calm and do not run. Stand tall, make yourself look as large as possible, and make noise. Back away slowly while maintaining eye contact. If the mountain lion attacks, fight back aggressively using anything available as a weapon.
Do mountain lions attack humans?
While mountain lion attacks are rare, they can occur. Most attacks involve small children or people who are alone and unaware of their surroundings. Taking preventative measures and being prepared for an encounter can significantly reduce the risk.
What are the signs that a mountain lion is nearby?
Signs of mountain lion activity include tracks, scat (droppings), scratch marks on trees, and the presence of killed prey (often partially buried). Paying attention to your surroundings and being aware of these signs is crucial in mountain lion country.
Does human urine deter mountain lions?
While some anecdotal evidence suggests that human urine might temporarily deter mountain lions, it’s not a reliable or recommended method. Consistent and proven deterrents are far more effective.
Are there any plants that repel mountain lions?
There are no known plants that reliably repel mountain lions. While strong-smelling plants might temporarily discourage them from an immediate area, they are not a substitute for other preventative measures. Focus on eliminating attractants and creating physical barriers.
How do I protect my livestock from mountain lions?
Protecting livestock requires a multi-faceted approach. Secure livestock in barns or pens at night, use high fencing, consider livestock guardian animals (LGAs), and remove any potential attractants such as spilled feed. Vigilance and consistent management are essential.
Is it safe to hike alone in mountain lion country?
Hiking alone in mountain lion country is riskier than hiking in a group. Mountain lions are less likely to approach groups of people. If you must hike alone, make noise, be aware of your surroundings, and carry a deterrent such as an air horn or pepper spray. Always inform someone of your hiking plans.
How often should I inspect my property for signs of mountain lion activity?
Regular inspections are crucial, especially if you live in an area with known mountain lion populations. Inspect your property at least weekly, paying close attention to areas where mountain lions might find shelter or food. Early detection can help prevent problems before they escalate.
What is the most important thing to remember about coexisting with mountain lions?
The most important thing is to be respectful of their space and to take proactive steps to minimize the likelihood of encounters. Understanding their behavior, eliminating attractants, and being vigilant are key to safe coexistence. What keeps mountain lions away ultimately boils down to minimizing the incentive for them to approach in the first place.
