What Are Javelinas?
Physical Characteristics
Javelinas are often mistaken for wild pigs, but they are actually part of the peccary family, which is native to the Americas.
These animals typically weigh between 35 to 60 pounds and have a stocky build with a bristly coat of dark hair.
The most distinguishing feature of javelinas is the “collar” of white fur around their necks, which gives them the name “collared peccary.”
They have sharp, short tusks that they use for both defense and foraging. [Will Javelinas Attack Humans?]
While they lack the strong eyesight of some other animals, javelinas have an acute sense of smell, which helps them locate food and navigate their environment.
Habitat and Range
Javelinas are well-adapted to arid and semi-arid environments, such as deserts, grasslands, and shrublands. [Will Javelinas Attack Humans?]
They are most commonly found in the southwestern United States, including Arizona, New Mexico, and Texas, as well as in northern Mexico.
Within these habitats, javelinas prefer areas with dense brush, cacti, and other desert vegetation that offers both food and cover from predators.
Javelinas are also known to venture into suburban areas, where they may be attracted by gardens, garbage, and other human food sources.
Understanding Javelina Behavior
Social Structure
Javelinas are social animals that live in groups known as herds or bands. These herds typically consist of 6 to 12 individuals, though larger groups have been observed.
Within these groups, javelinas engage in various social behaviors, such as grooming, nuzzling, and even vocal communication.
The close-knit nature of their social structure helps them protect one another from predators. They rely on each other for safety and companionship, often moving and foraging together.
If one member of the group senses danger, it can alert the rest, triggering a collective defensive response.
Diet and Feeding Habits
As herbivores, javelinas have a diet that primarily consists of desert plants, roots, fruits, and cacti. Prickly pear cactus is a staple food source for them, providing both nourishment and hydration, as its pads contain water.
They are opportunistic feeders and may also consume insects and small vertebrates if the opportunity arises. [Will Javelinas Attack Humans?]
In suburban areas, javelinas are known to scavenge for food in gardens, garbage cans, and pet food left outside, which can sometimes bring them into closer proximity with humans.
Activity Patterns
Javelinas are crepuscular, meaning they are most active during the early morning and late evening, avoiding the heat of the day by resting in shaded or sheltered areas.
This behavior helps them conserve energy and avoid the intense sun common in their habitats.
Because of their crepuscular nature, encounters with javelinas often occur during these times, such as early morning jogs or evening strolls.

Why Do Javelinas Attack Humans?
Perceived Threats
In general, javelinas are non-aggressive and prefer to avoid humans. However, like many animals, they will defend themselves if they feel threatened or cornered.
Javelinas have an instinct to protect their young and will react aggressively if they perceive a threat to their herd.
This is especially true if they have young with them, as the adult javelinas are highly protective of their offspring.
The presence of dogs can also trigger an aggressive response, as javelinas may see them as predators. [Will Javelinas Attack Humans?]
Defensive Behavior
Javelinas have several defensive behaviors they may display if they feel threatened.
These can include growling, raising the hair on their backs, showing their tusks, and even charging at the perceived threat.
These behaviors are usually warning signs, meant to deter the threat from approaching further. [Will Javelinas Attack Humans?]
In most cases, the javelina will stop short of making physical contact, but it’s essential to heed these warning signs and give them space.
Accidental Encounters
While intentional aggression is rare, accidental encounters can sometimes lead to javelina attacks. For example, if a person or pet surprises a javelina, the animal may react defensively out of fear.
This can happen when humans accidentally wander too close to a resting javelina or startle a herd. [Will Javelinas Attack Humans?]
In such situations, the javelina’s response is typically brief but can be intense, especially if they feel cornered or if escape routes are limited.
How to Avoid Javelina Encounters
Safety Tips
To minimize the risk of a javelina encounter, consider the following safety tips:
- Keep a Safe Distance: If you encounter a javelina, maintain at least a 20-foot distance. Observing from afar allows you to enjoy their presence without disturbing them.
- Do Not Feed Them: Feeding javelinas is not only dangerous but may also be illegal in certain areas. Feeding wild animals encourages them to lose their natural fear of humans, increasing the likelihood of future encounters.
- Secure Food Sources: Javelinas are attracted to garbage, bird feeders, pet food, and other food sources. Secure these items in animal-proof containers, and avoid leaving them outside.
What to Do If Confronted
If you find yourself in close proximity to a javelina, follow these steps to avoid an escalation:
- Stay Calm: Avoid making sudden movements, as these may be perceived as a threat.
- Slowly Back Away: Create distance without turning your back. If you need to, walk backward while keeping an eye on the javelina.
- Make Yourself Appear Larger: Stand tall, raise your arms, and speak in a firm voice. This can help deter the javelina by making you appear more intimidating.
Deterring Javelinas from Residential Areas
For those living in javelina-populated areas, here are some additional steps to help keep them at bay:
- Install Fencing: A sturdy fence, at least four feet high, can effectively keep javelinas out of your yard. [Will Javelinas Attack Humans?]
- Remove Attractants: Clean up any fallen fruit, secure garbage cans, and avoid leaving pet food outside.
- Use Non-Toxic Repellents: There are various animal repellents available that are safe for the environment and can help keep javelinas away from your property.

Injury Risks
Though javelinas are generally not a significant danger to humans, their sharp tusks can cause injuries if they make physical contact.
Most injuries from javelina encounters are minor and are the result of defensive behavior, such as a quick bite or tusk swipe. [Will Javelinas Attack Humans?]
It’s worth noting that javelinas are not known to carry rabies, which reduces some health risks associated with their bites.
Frequency of Attacks
Javelina attacks on humans are quite rare. When they do occur, they are typically brief and non-lethal. More commonly, javelina-related incidents involve pets, particularly dogs.
These animals can trigger a defensive reaction from javelinas, leading to aggressive encounters.
Wildlife officials emphasize that most incidents can be avoided by respecting the animal’s space and following safety guidelines.
Medical Treatment
In the unlikely event of an injury from a javelina, it’s essential to seek medical treatment, especially if the wound is punctured or bleeding.
Wound cleaning and treatment can help prevent infection. [Will Javelinas Attack Humans?]
While javelinas are not significant carriers of diseases transmittable to humans, medical attention is always recommended following an encounter with wildlife.
Do Javelinas Pose a Threat to Pets?
Interactions with Dogs and Other Animals
Javelinas are particularly wary of dogs, which they may perceive as a predator, similar to the coyotes that threaten them in the wild.
Even if your dog is on a leash, javelinas may feel provoked by barking or sudden movements. Pet owners should be cautious when walking dogs in areas where javelinas are known to reside.
Protecting Pets from Javelinas
To help keep pets safe from javelinas, consider the following:
- Leash Pets: Always keep dogs on a leash when walking them in areas with known javelina populations. This can prevent pets from chasing or approaching javelinas.
- Supervise Outdoor Time: Avoid leaving pets unattended in areas where javelinas might wander, especially during dawn and dusk.
- Fence Your Yard: A secure fence can help prevent javelinas from entering your property, reducing the likelihood of encounters with pets.
