The American badger digs rattlesnakes out of their dens, absorbs their bites, and eats them. In South Dakota, it is considered the rattlesnake's most important predator.
A rattlesnake in its den is supposed to be safe. The burrow is narrow, dark, defensible, and the snake can coil and strike at anything that enters. Against a badger, the den is a trap. The badger does not enter the hole. It excavates around it. The same claws that can dig through blacktop and rip open a ground squirrel tunnel in seconds will peel the roof off a rattlesnake den and expose the coiled animal to open air, where the badger's jaws are waiting. The snake strikes. The badger takes the hit. The badger keeps digging.
DesertUSA describes this plainly: the badger hunts one of its favorite prey, the rattlesnake, with impunity because, with the exception of its nose, it seems to be immune to the serpent's venom.
The resistance is not fully understood. The badger's first line of defense is physical, not chemical. Its skin is extraordinarily thick, loose, and tough, a hide that moves independently of the muscle and bone beneath it. When a rattlesnake strikes a badger's flank or shoulder, the fangs often fail to penetrate through the loose skin deep enough to reach vascularized tissue where the venom would enter the bloodstream. The skin absorbs the strike the way a heavy leather jacket might absorb a thorn. Some researchers believe there is also a biological component, a resistance in the badger's bloodstream that neutralizes whatever small amount of venom does get through, but this has not been confirmed with the same molecular precision as the documented venom resistance in honey badgers or mongooses.
What has been confirmed is the outcome. Badgers eat rattlesnakes routinely across the western United States. They eat prairie rattlesnakes, western diamondbacks, and timber rattlesnakes in the regions where both species overlap. They dig them from winter dens where rattlesnakes congregate in large numbers, sometimes dozens of animals coiled together in a single hibernaculum. A badger that finds a rattlesnake hibernaculum in October or November has found a refrigerator stocked with slow, cold, barely responsive prey that cannot mount a fast strike because its muscles are too cold to contract at full speed. The badger digs in and feeds.
During warmer months, when rattlesnakes are active and their strike speed is at full capacity, the badger still hunts them. The approach is what Biology Insights describes as brute force: the badger uses its heavy build and powerful jaws to quickly subdue the snake before consuming it. There is no circling, no feinting, no careful avoidance of the head the way a roadrunner or a kingsnake might approach. The badger is built like a brick. It weighs 15 to 25 pounds, carries most of its mass low to the ground, and its muscular neck and flat skull give its jaws a leverage advantage over anything it can get its teeth around. It bites and it does not let go.
A rattlesnake in the jaws of a badger is dead in seconds.
The nose is the weak point. The skin on a badger's snout is thinner and more vascularized than anywhere else on the body. A rattlesnake bite to the nose can deliver venom directly into tissue with heavy blood flow, bypassing the armor that protects the rest of the animal. Badgers that are bitten on the nose may experience swelling, pain, and in rare cases, serious envenomation. Whether badgers have learned to protect their noses during snake encounters, by tucking the head and leading with the armored forehead and jaw, is not documented in the literature. But the pattern is consistent across multiple sources: everywhere else on the body, the venom does not seem to matter.
The Animal Diversity Web at the University of Michigan lists the American badger as a significant predator of venomous snakes and notes its role in controlling their populations. A single badger holding a territory that includes a rattlesnake hibernaculum can reduce the local snake population year after year by raiding the same den site every autumn. The snakes cannot relocate. They return to the same hibernaculum their mothers used because the sites with the right depth, temperature, and drainage are rare. The badger knows where they are. It comes back every year. The snakes come back every year. One side has venom. The other side does not care.
