The house centipede is a long-legged, yellowish-grey centipede that often shares homes with people. It comes from the Mediterranean region and has spread across much of the world. It is fast, has very long legs, and eats household pests, so it is useful to have around.1

すんでいる場所

Native to the Mediterranean region. Now found across much of Europe, Asia, North and South America, and introduced to Australia.1

ホーム

Outdoors, it prefers cool, damp places such as under rocks, woodpiles, bark dust, and piles of leaves or compost. Indoors, it is found mostly in dark or dimly lit areas such as basements and garages, and also in bathrooms, kitchens, bedrooms and offices. It often emerges during garden watering, and it is most often seen in spring and autumn.1

何を食べるの？

It eats spiders, bed bugs, termites, cockroaches, silverfish, ants and other household arthropods. It hunts mostly at night, relying mainly on its antennae, and catches prey by jumping onto it or by using its legs in a 'lassoing' technique.1

毒パワー

かむ

かむときに、毒が牙や歯から出るよ。

その毒（かむ・刺す毒）はどうなるの？

It has a mild venom, which it injects through small claw-like structures called forcipules. Its venom is used mainly to subdue prey. In a bite on a person, the effect is limited to mild pain and swelling in the local area, similar to a bee sting.1

人にとってどれくらい危険？

人への危険: 軽いハチに刺されたくらいか、それ以下。人にはほぼ無害。

House centipedes pose essentially no threat to people. They are not aggressive and usually flee when disturbed. Stings are rare and usually happen only when the centipede is cornered or handled roughly. Their forcipules have difficulty penetrating human skin. Allergic reactions have been reported but are rare, and nearly all successful bites heal quickly without complications.1

こわいとき、どうするの？

When disturbed, it usually runs away quickly, and it can detach any legs that have become trapped.1

かまれたら

かまれたところを洗い、冷やすか、痛みにはぬるま湯につけて、悪くなったら医療の助けを受けよう。

安全に過ごそう

野生の動物には、小さくても、ねているように見えても、死んでいるように見えても、ぜったいにさわったり、つかまえたり、からかったりしないこと。
近づかないで。出会ったら落ちついて、ゆっくりあとずさりして、そのまま行かせてあげよう。

知っておく価値あり

データ

It can detach its own legs if they become trapped, which helps it escape danger.1

It can tell harmful prey from safe prey, and it changes how it feeds depending on the danger. With wasps, it retreats after stinging to let the venom take effect.1

Its tail-like hind legs look like antennae, so when it is at rest it is hard to tell its head end from its tail end.1

Unlike most centipedes, it has well-developed faceted eyes, although it hunts mostly by smell and touch through its antennae.1

Its blood contains proteins that carry oxygen, which is unusual among centipedes.1

It can live its whole life inside a building, usually on the ground floor of homes.1

うそ・ほんとう

うそ： House centipedes are dangerous and likely to attack people.

ほんとう： They are not aggressive and usually run away. Their stings are rare and cause only mild, local pain and swelling.1
