Centipedes, often misunderstood and sometimes feared, are fascinating arthropods playing a crucial role in their ecosystems. This article delves into the dietary habits of centipedes, particularly focusing on the giant centipede, exploring what they eat, where they live, and how they interact with humans. Understanding these aspects can help us appreciate their ecological significance and manage their presence in our living spaces.
Introduction to Centipedes
Centipedes are arthropods characterized by their elongated bodies and numerous pairs of legs. Often mistaken for millipedes, they are distinguished by having one pair of legs per body segment, while millipedes have two. Centipedes are primarily carnivorous, actively hunting and preying on a variety of smaller creatures.
Centipede Diet and Prey: A Carnivorous Lifestyle
Centipedes are primarily carnivorous arthropods, consuming a variety of insects and small animals. Their diet reflects their role as efficient predators, crucial for maintaining ecological equilibrium.
What Do Centipedes Eat?
Centipedes eat various insects and other small animals and invertebrates. The scutigera coleoptrata, commonly known as the house centipede, feasts on crickets, cockroaches, silverfish, moths, and earthworms. Centipedes consume a variety of invertebrates and small insects as part of their diet, preying on creatures such as ants, spiders, bed bugs, termites, and cockroaches.
Dietary Preferences Among Species
Centipede species exhibit a diverse range of dietary preferences influenced by their size, species type, and prey availability in their surroundings. Smaller varieties tend to consume insects and assorted small invertebrates as part of their diet, while larger types of centipedes may hunt down amphibians or even small mammals.

The Giant Centipede's Appetite
The name “Giant Centipede” is applied to a variety of species. Those most commonly seen in trade are the Amazonian Giant Centipede (Scolopendra gigantean) and the Vietnamese or Red-headed Centipede (S. Large individuals of S. gigantea have been known to employ unique strategies to catch bats with muscular strength.
- Scolopendra gigantea: Also known as the Peruvian giant yellow-leg centipede or Amazonian giant centipede, this species is naturally found in northern South America. Scolopendra gigantea is a carnivore that feeds on any other animal it can overpower and kill, including other invertebrates such as large insects, worms, snails, spiders, millipedes, scorpions, and even tarantulas, but also small vertebrates including small lizards, frogs (up to 95 millimetres [3+3⁄4 in] long), snakes (up to 25 centimetres [10 in] long), sparrow-sized birds, mice, and bats.
Hunting Behavior and Predatory Strategies
Centipedes showcase a variety of hunting behaviors tightly linked to their environmental preferences and nocturnal lifestyles. Centipedes are agile hunters, relying on their speed and venom to overpower their victims. Equipped with forcipules, modified front legs evolved into venomous fangs, centipedes use these to deliver a venomous bite. The forcipule's puncture allows them to inject venom directly into the prey, immobilizing or killing it before consumption.
Their rapid movement and nimbleness enable them to pursue potential prey swiftly, often ambushing them unexpectedly. Thanks to this deadly blend of agility and venom potency, centipedes are proficient in capturing a vast range of prey items that include tiny insects as well as sizeable arthropods.
Cannibalistic Tendencies
Various species of centipedes have exhibited cannibalistic tendencies, with bigger specimens preying on their smaller or wounded counterparts. The practice of cannibalism in centipedes reflects their capacity to adjust and persist, guaranteeing that the most robust members prosper.
Centipedes as Scavengers
Centipedes in the wild are also scavengers. They readily accept pre-killed food or even "prepared food". For babies in particular some people freeze some crickets, cut them into pieces and divide them among deli cups with baby Scolopendras in them. To insure a wider variety of nutrient in the diet some supplement with a mixture of Gerber's baby food with fish flake food.

Habitat and Environmental Preferences
Centipedes are attracted to crevices and dark places, seeking out habitats that provide adequate moisture, such as soil, leaf piles, rocks, and compost areas.
Where Do Centipedes Live?
Centipedes thrive in dark, moist environments such as basements, soil, leaf piles, rocks, and compost areas. The house centipede adapts well to indoor spaces like basements where humidity is higher, while wild centipedes tend to favor outdoor settings, including lush tropical regions, where they can burrow to maintain their moisture levels. Scolopendra gigantea can be found in tropical or sub-tropical rainforest and tropical dry forest, in dark, moist places such as in leaf litter or under rocks and logs. They climb readily and will utilize hiding spaces under bark in trees.
Importance of Moisture
Centipedes must live in humid environments, such as the underside of rocks or in the soil. Centipedes have spiracles located at segments 4,6,8,11,13,15,17,19, and 21. Through these openings, centipedes can lose a lot of water quickly and dehydration can occur.
Centipedes and Human Interaction
For many homeowners, centipedes can be a nuisance. When centipedes venture into your home, they're usually seeking shelter or hunting for smaller household pests.
Benefits of Centipedes
Centipedes serve as natural pest control, targeting spiders, bed bugs, roaches, and other household pests. Their predacious lifestyle minimizes the need for chemical repellents, contributing to a balanced home ecosystem. Centipedes play a vital role in keeping pest populations in check and contributing to ecological equilibrium. They are essential in maintaining the ecosystem’s equilibrium by regulating the numbers of small invertebrate populations.

Risks Associated with Centipedes
While centipede bites may lead to swelling and pain, serious allergic reactions are rare. Centipede bites are typically not serious and occur rarely, usually subsiding quickly. However, at least one human death has been attributed to the venom of S. gigantea. In 2014, a four-year-old child in Venezuela died after being bitten by a giant centipede which was hidden inside an open soda can.
Centipede Control Methods
If the presence of centipedes in your home becomes a significant concern, pest control methods ranging from reducing moisture in the home to setting up traps can help in getting rid of centipedes.
- Preventative Measures: To keep centipedes from invading your house, you should implement a number of important measures. By closing any openings or cracks on the outside of your house, such as those near windows and doors, you can stop centipedes from entering. Maintaining cleanliness in outdoor spaces by clearing away rubbish and cutting back plants will help discourage these pests.
- Natural Strategies: Natural strategies for eliminating centipedes encompass applying diatomaceous earth that disrupts their outer shell causing them to dehydrate. Utilizing diatomaceous earth or boric acid is an effective approach as these substances erode the protective exoskeletons of centipedes and ultimately cause them to become dehydrated.
- Professional Assistance: As with any pest problem, calling a pest professional is the best way to ensure you get rid of centipedes for good. In situations where a substantial infestation occurs, it’s wise to seek assistance from a professional in pest management.
Addressing Infestations
To decrease the likelihood of centipedes taking up residence inside a home, it’s important to pinpoint how they’re getting in and address excessive moisture issues. House centipedes often infiltrate homes as they seek refuge or pursue various smaller pests found within households. These arthropods are particularly drawn to environments offering nourishment, humidity, and concealment. Should you regularly encounter house centipedes inside your living space, it may indicate a significant pest problem that warrants immediate attention.
Centipedes in Gardens
Centipedes found outdoors are voracious carnivores, feasting on various insects and small invertebrates that inhabit their surroundings. Reflecting the array of available prey within their environment, outdoor centipedes boast an eclectic diet. Centipedes in gardens are known to feed on a variety of soil-dwelling insects, larvae, worms, and slugs. When centipedes are found within a garden environment, it signifies an active ecosystem where natural pest control mechanisms are effectively functioning.
Dispelling Myths and Misconceptions
Despite the fact that centipedes possess pincers and are capable of biting, their bites tend to be non-critical and seldom lead to any grave health complications. It is critical to assess the actual threat they present as humans often view them as perilous due to their venom-bearing bites. While a bite from a centipede may result in some discomfort, it’s rare for an individual to have an allergic reaction. Understanding the true hazard posed by centipedes can aid in addressing their existence without undue alarm. Although experiencing a bite from one can cause pain, such incidents do not pose fatal risks.
Centipedes as Part of the Arthropod Family
Centipedes, including house centipedes, are part of the arthropod family and are relatives of spiders and scorpions. They are not insects.
Centipedes in Captivity
Centipedes will thrive on a diet of crickets, roaches and earthworms. Wild-caught insects may be offered to help balance the diet. In captivity they readily accept pre-killed food or even "prepared food".
Feeding Practices
That's literally how some people feed them - either directly tong-feeding them, or dropping the feeder right next to them.
Housing Considerations
It is generally recommended to use RUBs/plastic tubs for housing pedes.
