Javelina (collared peccary)

Pecari tajacu · Artiodactyla: Tayassuidae[5][3]

Javelina, or collared peccaries, are native hoofed mammals of the desert Southwest and Texas brushlands. They wander into neighborhoods for lush plants, birdseed, garbage, water and shade, and herds that learn to find food at homes can cause real trouble, especially for dogs.[1][2][3]

How to identify it

  • A stocky hoofed mammal weighing about 40 to 60 pounds and standing about 19 inches tall.[1][3]
  • Coarse hair is peppered black, gray and brown, with a faint band of lighter hair around the shoulders that looks like a collar.[1][3]
  • Unlike pigs, it has small, rounded ears, no visible tail and only one dewclaw on each hind leg.[4][3]
  • Young javelina are called reds because of their reddish color.[3]
  • A scent gland on the rump gives off a musky odor used to mark territory and recognize herd members.[3][1]

Look-alikes

Look-alikeHow to tell them apart
Feral hogHogs are much bigger, with mature animals often reaching 190 pounds or more, and have longer, pointed ears and an easily seen tail.[4]

Where it lives

Found in Arizona, New Mexico and Texas and through much of Latin America; in Texas they live in the South Texas Plains, Trans-Pecos, Edwards Plateau and Rolling Plains.[3]

Biology and life cycle

Javelina belong to the peccary family, a group of hoofed mammals that originated in South America; they are not pigs.[1][3][4]

They live in herds of a few to more than 20 animals, which help with defense, staying warm and social contact.[1][3]

Their eyesight is very poor, but their sense of smell is keen.[1]

They are most active at night but may be out during the day in cold weather.[1]

They eat mostly plants, including prickly pear and other cacti, succulents, bulbs, roots, mesquite beans and seeds, plus some insects, grubs and garbage.[1][3]

Javelina can breed year-round, with litters usually of two young, and live about 7 to 10 years.[3][1]

Damage and signs

  • They dig up and eat garden plants, flowers, bulbs and succulents, and they raid birdseed, pet food, table scraps and garbage.[1][2]
  • They also come for water from hoses, pools and irrigation, and shelter under porches, mobile homes, crawlspaces and other cave-like spots.[1]
  • Javelina drawn to one yard often visit neighboring lots too.[2]

Health risk

Dogs and javelina can seriously hurt or kill each other; javelina may act defensively when cornered, protecting young, or when they hear or smell a dog. Anyone bitten by a javelina must seek medical attention immediately.[1]

Control

Prevention

Plant bulbs javelina dislike, such as iris and narcissus, instead of favorites like tulips.[2]

If you meet javelina while walking a dog, stay away from them and quickly lead your dog in another direction; keep pets leashed or supervised outdoors.[1][2]

Keep them out

A single strand of electric fence about 8 to 10 inches off the ground is the most effective way to protect a garden.[1]

For the whole yard, use a 4-foot block wall or chain-link fence with a concrete footer buried 8 to 12 inches deep, and close off openings under porches and buildings.[1][2]

Sanitation

Never feed javelina. Store garbage securely, feed pets indoors, and keep birdseed and water off the ground and out of reach.[1][2]

Traps and physical control

Scare them off with loud noises, a garden hose, small rocks, or a squirt gun of vinegar or diluted ammonia (1 part household ammonia to 9 parts water).[1][2]

When to call a professional

Call Arizona Game and Fish if a javelina is acting aggressively toward people, is trapped and can't leave on its own, or is in someone's possession.[1]

If javelina are in your yard

Give a confined javelina a way out: open a gate, have everyone leave the area, and let it leave on its own.[1]

Because their eyesight is poor, javelina may seem to charge when they are really trying to escape.[1]

Ask neighbors to remove food and water sources too, since herds move between nearby lots.[2]

Legal status

Javelina are a native big game species in Texas, hunted only with the proper license and in set seasons and counties.[3][4]

In Arizona it is unlawful to injure or kill game animals outside legal provisions, and it is unlawful to trap javelina.[1]

In Pima and Maricopa counties, intentionally feeding wildlife other than birds and tree squirrels is a petty offense under the No Feeding Wildlife Law.[2]

Common questions

Are javelina wild pigs?
No. They are peccaries, a separate family of hoofed mammals; they are smaller than feral hogs, with round ears, no visible tail and a pale collar.[1][4]
Are javelina dangerous to my dog?
They can be. Dogs are natural predators of javelina, and the two can seriously injure or kill each other, so keep dogs leashed and steer them away.[1]
Why do javelina keep coming back to my yard?
They are after food, water and shade. Lush plants, birdseed, garbage, pet food and hose water can all keep a herd returning.[1][2]
