Yes, a loud blast is one of the methods wildlife agencies in both Arizona and Texas tell homeowners to use on javelinas. The catch is that javelinas don't see well, they move as a herd, and they react badly to dogs. So how and where you sound the horn matters as much as how loud it is.
What Arizona and Texas Wildlife Agencies Actually Recommend
Neither state agency mentions train horns by name, but both put loud noise first. Texas Parks and Wildlife's Trans-Pecos javelina page puts it plainly: when javelinas show up around your home, "attempt to scare them off by making loud noises and throwing rocks." It also asks you to tell your neighbors, because it often takes every household on the street to fully solve a javelina problem.
In Arizona, a University of Arizona Cooperative Extension guide lists what the Arizona Game and Fish Department recommends for unwanted wildlife:
- Make loud noises: shout, bang pots and pans, or rattle a can with pebbles in it.
- Wave your arms or objects like sticks and brooms.
- Throw small stones or cans.
- Spray the animal with a hose.
Game and Fish has repeated the same advice in Arizona news coverage: loud noises, rocks tossed toward the animals, or a garden hose. Some reports also mention spraying vinegar or diluted ammonia toward the herd, but never into their eyes and never near wetlands. A portable train horn is a louder, more repeatable version of the noise method. Nobody has to stand in the yard banging pots, and you can sound it from a doorway, a truck cab, or with a remote from inside the house.
Why Javelinas "Charge" (and Why That Changes How You Use a Horn)
Most javelina "attack" stories are really panicked herds. Texas Parks and Wildlife explains that when one animal sounds the alarm, the whole herd scatters in every direction. With 15 or 20 animals running at once, at least one is likely to come straight at you. The same TPWD material says javelinas usually aren't aggressive toward people and normally retreat unless they're cornered or startled.
Three facts from TPWD shape how you should use a horn:
- Poor eyesight. Javelinas see poorly and often stay near people longer than other wildlife do after being startled. One that runs toward you may simply be fleeing on the wrong line.
- Herds. Family groups usually hold 5 to 30 animals. Once the herd is alarmed, it can mill around making "whoof" sounds and popping its teeth until it feels safe again.
- Size and tusks. An adult can reach about 55 pounds and stand 18 to 20 inches at the shoulder. Its canine teeth are built for cutting, and they become weapons when the animal is cornered.
The practical takeaway: always sound the horn so the herd has a clear exit. Stand where you aren't blocking the gap they came in through, such as an open gate, a wash, or the gap under a fence. A blast from the side they need to leave toward can send panicked animals straight at you or into a dead-end corner of the yard.
Dogs Are the Biggest Risk Factor
If you only take one thing from this article, take this one: get the dog inside before you do anything else. TPWD notes that javelinas see dogs as coyotes, which prey on their young. Fights between a dog and a herd can leave the dog dead or badly injured, and other herd members often join in. An Arizona Game and Fish spokesperson told Phoenix-area media that dogs are the second leading cause of javelina bites on people. The first is people feeding them.
The order of operations matters:
- Bring dogs indoors or into a closed garage first. A barking dog plus a horn blast is the classic recipe for a herd that turns and fights.
- Get yourself behind a door, inside a vehicle, or on the far side of a wall.
- Then sound the horn in short bursts, two or three seconds each, with a pause between them so the herd can pick a direction and go.
Texas Parks and Wildlife also advises against letting dogs run loose or leaving them tied up anywhere javelinas can reach them. A dog on a tie-out can't escape a herd.
Picking a Horn and Setting It Up for Yard Duty
For javelinas, the goal is a sharp, sudden noise that makes the herd decide your yard isn't safe. You don't need maximum volume. Our Dual horns are rated at 130 dB, Quad horns at 140 dB, and Extreme/Boss Series at 150 dB and up. Each 10 dB step is roughly twice as loud to the ear. On a typical suburban lot, a Dual or Quad horn is usually plenty. Ranch and acreage owners trying to move a herd off a stock tank or out of a far pasture get more use out of the higher tiers.
The Quad Trumpet Train Horns are the middle option most homeowners pick. They come in versions for most major tool-battery platforms, so you can probably run one on the packs already sitting in your garage.
If you're on the Milwaukee® M18™ platform and want reach across open desert or a big rural lot, the Extreme Series Train Horn for Milwaukee® 18v Battery is the one we'd point you to. It's our 150 dB tier and runs on any M18™ pack you already own.
The real upgrade for javelina duty is the remote. Javelinas feed mostly at night in summer, according to TPWD, and their favorite spots tend to be dark corners: under a deck, beside the AC unit, or in the oleanders. A horn mounted at that spot and triggered with a remote from inside lets you move the herd without stepping out into the dark with them. Our wireless remote horns reach up to 2,000 ft with the long-range remote. If you want the horn to fire on its own when the herd walks in, our motion-sensor setup guide is linked at the end of this article.
A few rules for use around the house:
- Point the trumpets toward the herd and away from people, your own pets, and your neighbors' windows.
- Don't fire it right next to anyone's ears, including your own. The National Institute on Deafness and Other Communication Disorders lists sirens at 110 to 129 dB, and every one of our tiers is rated above that.
- Use it to move animals, not to chase them. Following a herd while you blast the horn is how people end up cornering one.
Noise Alone Won't Keep Them Away: Fix the Attractants
A horn moves a herd tonight, but the herd will be back if your yard still has food, water, and shelter. Texas Parks and Wildlife and the University of Arizona extension guide agree on the fixes:
| Attractant | Fix |
|---|---|
| Garbage and pet food | Store garbage securely and feed pets indoors. Put trash cans out the morning of pickup, not the night before. |
| Bird feeders and fallen seed | Move feeders where javelinas can't reach them and keep the ground under them clean. |
| Crawlspaces, decks, mobile homes | Block the openings. Use solid skirting under trailers and decks. |
| Low shrubs | Trim them up from the ground so they don't offer cover. |
| Holes under net-wire fences | TPWD notes javelinas generally reuse existing openings rather than digging new ones. Some landowners leave a pegged gap so the herd stops tearing new holes. |
Feeding is also a legal issue in Arizona. Under A.R.S. 13-2927, intentionally, knowingly or recklessly feeding or attracting wildlife is a petty offense in counties with more than 280,000 people. That covers the Phoenix and Tucson metro areas. The law exempts birds and tree squirrels, which is why a messy bird feeder can still get you in trouble if javelinas are cleaning up underneath it.
Leave the herd itself alone. Javelinas are a game animal in both states. In Texas, TPWD says they can be taken only with a hunting license, in season, and in counties that have a season. Many cities also ban firing a gun inside city limits. Scaring them off is legal and recommended. Trapping, injuring, or killing them on your own is not something to improvise.
FAQ
Will a horn make a javelina attack me?
It's unlikely if the herd has an exit. TPWD describes most "charges" as a startled herd scattering, with poor eyesight sending some animals the wrong way. Sound the horn from behind a door or wall, from the side away from their escape route, and keep dogs inside.
Will javelinas get used to the horn?
Repeated noise works best when you also remove the reason they came. If the yard still has garbage, pet food, or a cool crawlspace, the herd has a reason to put up with the noise. Fix the attractants and the horn becomes a reminder instead of a nightly battle.
Is a train horn better than banging pots?
It does the same job. Wildlife agencies recommend loud noise, and a battery horn is just louder, quicker to grab, and can be fired by remote. That last part matters with an animal you'd rather not meet face to face in the dark.
Does the same approach work on feral hogs?
Partly. Javelinas are not true pigs, and feral hogs are much larger and behave differently. Our guide on whether train horns scare wild hogs covers the differences.
Javelinas are just one of the yard and trail visitors a horn can move along. Our deer, coyote and wildlife guide below covers the rest. If you also want a horn for the truck, start with our best train horns for trucks roundup.
