The Mediterranean recluse spider is a small spider that comes from the Mediterranean region. It has spread to many parts of the world through human travel and trade, and it is listed as one of the most invasive spiders in the world. Its bite can cause skin damage, so it is worth knowing what it looks like.1

It usually lives in caves, basements and tunnels, and prefers warm, generally dry weather. Where it is not native, it is often found in damp places such as basements, where it hunts cockroaches and silverfish. In 2021, spiders of this species were found in a university library basement, which led to the library closing for two days.1

Apa makanannya?

It is an active hunter that goes out at night to catch and kill insects, rather than waiting in a web. It mainly targets smaller insects, such as silverfish and cockroaches, because their soft bodies are easier to overcome.1

Kekuatan bisa

Gigitan

Bisanya keluar lewat taring atau gigi saat menggigit.

Apa efek bisanya?

Its venom contains an enzyme called sphingomyelinase D, which causes necrosis, meaning the death of skin and other tissue around the bite. Most cases are medically insignificant. In some cases, penetrating pain starts 2 to 8 hours after the bite, followed by burning, and the area becomes red and painful. A blister may form that turns dark blue with a sunken centre over several days. In rare cases, the blood and kidneys can be damaged, which can lead to kidney failure.1

Fakta

It is listed as one of the most invasive spiders in the world.1

It can survive for long periods without food and water, which makes it hard to control in homes.1

Young spiders shed their skins several times as they grow, and these skins often look pale and ghostly.1

Males hunt more actively than females, partly because they are also searching for a mate.1
