Hog Night Hunting: Thermal Gear
Night hunting for feral hogs is open in some states, licensed in others and prohibited in a few. What five state agencies say, how thermal and night vision differ, and what the CDC says about handling and cooking the meat.
For hunting hogs at night, thermal is the better tool for finding animals - it shows body heat in complete darkness - while night vision costs less and gives a more natural picture for identifying what you are looking at. Before either matters, though, there is a prior question: whether you may hunt hogs at night where you are at all. The answer differs sharply from state to state.
This page is not legal advice. The state rules below come from the agencies’ own publications, checked on 10 October 2026, and they change.
Why It Matters
Feral hogs do enormous damage. The US Department of Agriculture puts it this way: costs from feral swine damage and control are an estimated $2.5 billion each year in the U.S. agricultural sector alone. The same page reports that 12 states have eradicated feral swine since 2014.
Hogs are often most active after dark, which is why landowners and hunters turn to night optics.
Is It Legal Where You Are?
Do not assume. Feral hogs are not classed the same way everywhere, and some states that want them gone have concluded that sport hunting makes the problem worse.
| State | What the agency says |
|---|---|
| Texas | On private property, with the landowner’s consent, no hunting license is required, and there is no closed season or bag limit |
| Alabama | No closed season and no bag limit by day on private and leased land. Night hunting needs a nighttime feral swine and coyote hunting license and is limited to a special season - from the day after gun deer season closes to the opening day of archery deer season in that zone |
| Tennessee | Wild hogs are no longer big game. Landowners may shoot them year-round in daylight; night shooting with light, night vision or thermal requires a wild hog exemption from the agency, and the basic one covers February 1 to August 15 |
| Missouri | Taking feral hogs is prohibited on conservation areas and other Department of Conservation land; elsewhere the Department strongly discourages hunting them and asks people to report hogs instead |
| Kansas | A US Department of Agriculture assessment notes that state law prohibits hunting feral swine except for pest control |
Sources: Texas Parks and Wildlife Department, Alabama Department of Conservation and Natural Resources, Tennessee Wildlife Resources Agency, Missouri Department of Conservation and USDA APHIS (Kansas).
Missouri explains its reasoning, and it is worth reading even if you hunt elsewhere: shooting one or two hogs scatters the sounder and makes trapping efforts aimed at catching the entire group at once more difficult, because hogs become trap-shy and wary of baited sites.
Before you go, check four things with your own state agency: whether hog hunting is open to you at all; whether night hunting is, and with which lights or optics; whether you need a license or permit; and what applies on public land, which is usually stricter than private.
Thermal and Night Vision: How They Differ
Thermal imaging forms a picture from heat. A warm animal stands out against cooler ground whether or not there is any light, and through thin cover. What it shows is a shape, not detail.
Night vision amplifies the little light there is - or, in digital units, records near-infrared light, usually with the help of an infrared illuminator. The picture looks like a monochrome photograph, which makes it easier to tell what you are looking at. It depends on moonlight, starlight or the illuminator.
In practice:
- For finding animals, thermal is far quicker.
- For being sure of the target and what is behind it, night vision or a good thermal at close range - and if you are not sure, you do not shoot. A warm shape at night can be a calf, a dog or a person.
Many hunters therefore carry a handheld thermal for scanning and a scope - thermal or digital - on the rifle.
Buying Optics
We have tested none of these devices, so we name no models and give no prices. What to compare on the makers’ own specification sheets:
- Sensor resolution - more pixels give a more detailed image at distance.
- Lens and field of view - a wide view for scanning, a narrower one for identifying.
- Stated detection range - and what it means. A maker’s detection range is the distance at which a warm object can be noticed, not the distance at which you can tell what it is.
- Battery life in the cold, and whether batteries can be swapped in the field.
- Recoil rating, for anything that mounts on a rifle.
- Warranty and service in your country.
Check, too, that the device is legal for hunting in your state: some states restrict electronic optics or lights for some species.
Rifles and Cartridges
Hogs are heavily built, and a mature boar has a thick shield of tissue over the shoulder. Use a cartridge and a bullet that your state allows for hogs and that you shoot accurately, and keep the distance short enough to be certain of the shot at night. Your state’s regulations and hunter-education material are the place for minimum calibers; we do not set our own.
On where to aim, see the anatomy in our shot placement guide.
Tactics
- Food and water. Crop fields, pasture, creek bottoms and wallows are where hogs show at night. Scan from a distance before you move.
- Bait. Legal in some states and not in others. Check before you put anything out.
- Wind. Hogs have a keen nose. Approach from downwind or crosswind.
- Know the ground in daylight - fences, livestock, houses, roads - before you ever hunt it in the dark.
From the Air
Texas regulates the taking of feral hogs from aircraft through its aerial wildlife management permit, and outfitters there sell helicopter hunts under that system. Ask any operator to show you the permit they work under.
FAQ
Can hogs see thermal or infrared devices? A thermal imager emits nothing. An infrared illuminator does emit light, outside the range people see; we know of no published test of whether hogs notice it.
Can I eat feral hog meat? Yes, cooked through: the CDC recommends at least 165°F (74°C) inside for wild game meat because of trichinellosis. Feral swine can also carry brucellosis, and the CDC’s advice to hunters is to wear eye protection and latex or rubber gloves when handling carcasses; freezing, smoking, drying and pickling do not kill the bacteria.
Is a suppressor legal for hog hunting? That depends on your state’s law and its hunting regulations. Federal rules on suppressors changed in 2026 - Congress set the federal tax on them to $0 from 1 January 2026, by the Congressional Research Service’s summary, and the ATF has issued new guidance since. Read the ATF’s current pages and your state’s rules before you buy.
How many hogs can I shoot? Where hog hunting is open, there is often no bag limit - Texas and Alabama set none on private land. Other states do not allow sport hunting of hogs at all. Check yours.
Conclusion
Night optics make it possible to find hogs when they are active. Whether you may use them, and whether shooting hogs helps or hinders control where you live, is for your state agency to say - so start there. Then be certain of every target, handle carcasses with gloves, and cook the meat thoroughly.
