The smallest centipedes grow to no longer than 0.4 inches (1 centimeter) long, while the longest may reach over 12 inches (30 cm) long. SizeĬentipedes and millipedes come in a large range of sizes relative to each other. Unlike their centipede cousins, millipedes lack a waxy layer on their exoskeleton that would help retain water. Millipedes, however, prefer moist soil and leaf litter in deciduous forests, although a few species are found in grasslands or deserts. They live exclusively on land, although at least one species of giant centipede has been known to swim.Ĭentipedes are found in all sorts of terrestrial habitats, even caves deep underground, but they are especially noticeable in extremely dry environments deserts are home to some of the largest centipedes. (Image credit: Shutterstock) Habitatīoth centipedes and millipedes are found on every continent except Antarctica. Since both pests prefer humidity, homeowners should reduce moisture levels to keep millipedes and centipedes away.Centipedes have modified legs on the first body section that are tipped with venomous claws called forcipules. Also, their darting movements and disturbing appearance tend to cause panic. ![]() They feed on insects, so their presence may indicate a more serious infestation is afoot. ![]() On the other hand, centipedes gather in dark, dank spaces like basements and bathrooms. Some millipede species also secrete a fluid that irritates skin and leaves an odour. These garden pests live in the soil, attacking roots and stripping stems on young plants causing plant damage. centipedes cause different problems for homeowners because their diets differ. Depending on the species, a millipede can have up to 400 legs. They have two pairs of legs on each body segment rather than the centipede’s single set. Commonly found in garden soil, millipedes are dark coloured with rounded bodies. A millipede has a distinctly different appearance and far more legs than a centipede. Millipedes are longer and have rounded bodies with each body segment bearing two pairs of short legs. A centipede has a flat body with a single pair of long legs per segment. Though centipedes and millipedes seem the same, the pests share few common traits. What is the difference between centipedes and millipedes? However, their presence is unsightly and they are considered a nuisance.ĭue to the persistent nature of centipedes, their ability to navigate very small cracks, and the fact their presence may indicate an insect problem, it is essential to get the help of a professional pest control service to eradicate them and any other infestations.Ĭentipede infestations in homes may indicate the presence of underlying insect problems. How worried should I be about centipedes?Īlthough they possess venom potent enough to paralyze and kill insects, centipedes do not bite humans unless grabbed or accidentally stepped on, and their venom is not toxic enough to be dangerous. As predators, they ambush and then disable their prey by catching them in poisonous claws. They prey on other household pests, including spiders, beetles, moth larvae, ants, and worms, but will also prey on other centipedes. There are more than 70 species of centipedes in Canada, and while most do not interact with humans, house centipedes commonly invade homes to escape dry conditions outdoors or cold weather.Ĭentipedes congregate where there are large amounts of insects and seek out dark, damp places with plenty of small crevices and cracks, like basements, garages, and mulched gardens. Commonly Asked Questions Why do I have centipedes? Immature centipedes grow additional body segments and legs as they age, going through several developmental molts before reaching adulthood. When young centipedes hatch, they look like smaller versions of adults, though they have fewer legs. Life Cycleįemales lay eggs in underground nests. Look for molted exoskeletons, Prevent other insects invading, Keep your home clean and sanitary, Cover exterior vents and holes, Seal cracked pipes and loose/worn outdoor seals, Seal crevices and cracks in walls, Remove brush, firewood, and mulch, Keep mulch and flower beds free of weeds, well aerated and do not overwater. Dark, secluded areas in basements, under cabinets, and collections of firewood are common places for centipedes to congregate. ![]() Homeowners might also find molted exoskeletons given a present infestation. The best way to determine if centipedes are present is to look for them at night when they’re most active. Signs of an infestationĪs they do not typically leave lasting signs of infestation, damage buildings, or contaminate food, centipede infestations may go unnoticed for some time. Each of their body segments has a pair of legs slightly longer than the pair before it, which helps the pests move quickly. ![]() Centipedes are segmented arthropods and their leg count typically ranges anywhere from 30 to nearly 400 limbs.
