Centipedes are eaten by a wide range of animals, from backyard birds and toads to tropical mammals and snakes. Despite their venomous bite and quick movements, centipedes sit squarely in the middle of the food chain and serve as a reliable protein source for dozens of predator species across nearly every habitat on Earth.
Mammals That Eat Centipedes
Small insect-eating mammals are among the most frequent centipede predators. Shrews and moles encounter centipedes regularly while tunneling through leaf litter and soil, and both will eat them without hesitation. Mice also consume centipedes opportunistically, especially in woodland and grassland environments where the two overlap.
In tropical regions, larger mammals hunt the bigger centipede species. The Amazonian giant centipede, which can reach 30 centimeters long, is preyed upon by coatis, kinkajous, and opossums. These animals are skilled arthropod hunters with tough skin and quick reflexes that help them avoid or tolerate a centipede’s venomous bite. Mongooses, known for tackling venomous snakes, will also take centipedes when they come across them.
Birds: From Chickens to Eagles
Birds are some of the most enthusiastic centipede hunters. The most common bird predator might be the least glamorous: the domestic chicken. Free-ranging chickens scratch through soil and leaf litter constantly and will snap up centipedes on sight. Chickens’ thick, scaly legs give them some natural protection from bites, and their pecking speed usually overwhelms the centipede before it can mount a defense.
Wild birds hunt centipedes too, across a surprising range of species. Flycatchers have been observed catching centipedes and carrying them back to feed nestlings. Blue-winged pittas, ground-foraging birds found in Southeast Asia, include centipedes in the mix of invertebrates they bring to their young. Common hoopoes, which probe soft ground with their long curved bills, occasionally pull up centipedes and stab them repeatedly before swallowing them. Even raptors get in on the action. Crested serpent eagles have been spotted swooping down to grab centipedes from forest tracks. Australian magpies show visible excitement when firewood is split open and centipedes scatter from the logs.
Ground-feeding birds in general are well positioned to encounter centipedes, since both tend to occupy the same zone of leaf litter, fallen wood, and loose soil.
Reptiles and Amphibians
Lizards, toads, salamanders, and small snakes all eat centipedes regularly. Toads are particularly effective predators because they hunt in the same damp, dark microhabitats where centipedes thrive. A toad’s sticky tongue can snatch a centipede before it has time to flee, and toads are generally unbothered by the venom of smaller species.
Salamanders prey on centipedes in forest floor environments, where both animals shelter under rocks and decaying logs. Small snakes, especially species that specialize in invertebrate prey, will also consume centipedes. Some snake species swallow them whole, venom glands and all, with no apparent ill effects. Lizards tend to target smaller centipede species, grabbing them behind the head to avoid the venomous front claws (called forcipules) before consuming them.
Other Arthropods and Invertebrates
Centipedes don’t just fall prey to vertebrates. Larger centipede species sometimes eat smaller ones, making cannibalism a real threat within their own group. Large spiders, ground beetles, and scorpions will also attack and consume centipedes when the size matchup is favorable. Ants can overwhelm even large centipedes through sheer numbers, swarming and subduing them cooperatively.
How Predators Handle the Venom
Centipedes defend themselves with a pair of modified front legs that inject venom, and a bite from a large species can cause real pain even in humans. So how do so many animals eat them safely? Most predators rely on speed and technique rather than any special venom immunity. Birds stab or shake centipedes to kill them before swallowing. Mammals like shrews attack so aggressively that the centipede is dead before it can deliver a meaningful bite. Toads engulf smaller centipedes in a single strike.
Size also matters. The venom of a small house centipede is negligible to a bird or a mouse. It’s really only the large tropical species, like the Amazonian giant centipede, where venom becomes a serious factor, and even those are taken down by predators like coatis and opossums that have experience handling dangerous prey.
When Cats or Dogs Eat a Centipede
Domestic cats and dogs will sometimes catch and eat centipedes out of curiosity. For most small house centipedes, this is not a major concern, but it’s not entirely risk-free either. A centipede bite inside the mouth or throat can cause localized pain and swelling. Some cats experience vomiting or diarrhea after eating a centipede, likely from irritation caused by the exoskeleton or a mild venom reaction. Allergic responses, including itching, swelling, or in rare cases difficulty breathing, are also possible.
If your cat or dog eats a centipede and shows signs like excessive drooling, vomiting, swelling around the face, or obvious distress, those are worth a call to your vet. Most of the time the animal will be fine, but larger centipede species carry enough venom to cause a more significant reaction, especially in smaller pets.
