Why Do Llamas Spit? What Makes Llamas and Alpacas Spit

Spitting is llama-to-llama communication

The llama is a herd animal with a pecking order that is always being tested. Instead of fighting every time there is a dispute, llamas use a ladder of signals: a hard look, ears laid back, the head raised, a puff of air and, finally, a spit. Most quarrels end long before anyone gets wet.

Spitting lets a llama say “back off” without the risk of injury that comes with biting, kicking or neck-wrestling. Females in particular rely on it to keep order in the herd, while males are more likely to escalate to chest-ramming and wrestling when they compete for status.

Llamas do not spit at random. Most spitting happens in a few predictable situations, and knowing them explains nearly every spit people see on farms and in zoos.

The main reasons llamas spit

• Food. The most common trigger is feeding time. When hay or feed is put out, llamas jostle for the best spot, and a higher-ranking animal will spit at one that crowds in.
• Rank and personal space. A llama that feels a herd mate is too close, too pushy or challenging its position may spit to restore the pecking order.
• Rejecting a male. A female that is already pregnant typically refuses a male by sitting up, running off and spitting at him. Breeders use this “spit-off” response as an informal sign that a mating has worked, although it is not as reliable as a veterinary pregnancy check.
• Fear or stress. A frightened or cornered llama, or one that is being handled in a way it dislikes, may spit as a last warning.

Alpacas, the llama’s smaller cousins, spit for exactly the same reasons. So do the wild guanaco and vicuña, which shows that spitting is an old camelid behavior rather than something created by domestication.

What is in llama spit?

Not all “spit” is the same. Llamas grade it to match their mood:

The full spit comes from the first of the llama’s three stomach compartments, where plant food ferments before being brought back up and chewed as cud. That is why a real llama spit is green, gritty and sour-smelling, and why the smell can cling to clothes for hours. As a rule, the more upset a llama is, the more stomach material it brings up.

Llama spit is unpleasant but not dangerous. It is not venomous or poisonous; it is simply fermented plant material and saliva. Llamas themselves seem to dislike the taste: after a big spit, a llama often stands with its lower lip hanging loose and its mouth open for a while, as if airing it out.

Warning signs before a llama spits

Llamas almost always signal their mood before spitting, which gives other llamas, and people, time to step back. Common signs include:

• Ears pinned flat back against the neck.
• The nose and chin lifted high, so the llama looks down its face.
• A tight, puckered or bulging mouth as material is brought up.
• Gurgling, clucking or puffing sounds.
• Stiff, side-on posture toward the target.

Relaxed llamas, by contrast, hold their ears upright or pointing forward and move calmly. Ears that flick forward with a raised head usually mean curiosity or alertness rather than anger.

Do llamas spit at people?

They can, but it is uncommon. Most people who get spat on are simply standing in the line of fire between two llamas arguing over food. Visitors at farms and trekking centers are far more likely to be hummed at or ignored than spat on.

A bigger problem arises with llamas that were bottle-raised or heavily handled as babies, especially males. These animals can fail to learn normal boundaries with people and, as adults, treat humans like rival llamas, pushing, kicking and spitting. Camelid breeders call the extreme form of this behavior aberrant behavior syndrome, sometimes nicknamed “berserk male syndrome”. It is one reason breeders generally let crias grow up with their mothers and the herd.

Llamas raised normally in a herd tend to be calm, curious and confident with people. That temperament is why they are trusted as trekking companions, show animals and livestock guardians; see what llamas are used for.

Llamas vs alpacas: which spits more?

Both species spit, and neither deserves its reputation for spitting at people. There is no reliable count showing that one species spits more than the other, and individual temperament matters more than species. Alpacas are generally more nervous and stay closer to the herd, while llamas are bolder and more independent and are handled more often for packing and trekking, so they meet people more often.

In both, spitting is mainly an animal-to-animal signal. The other differences between the two are covered in alpaca vs llama, and the alpaca profile describes alpaca body language in more detail.

Myths about llama spit

• Myth: llamas spit whenever they are annoyed with people. Fact: llamas save most spitting for their own kind, and warning signs nearly always come first.
• Myth: llama spit is just water. Fact: a real spit is stomach contents, which is why it is green and smells so strongly.
• Myth: only llamas spit. Fact: alpacas, guanacos and vicuñas all spit, and it is a shared camelid behavior.
