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

Hidup di

Mediterranean and western Asia; now also Madagascar, south-east Asia, Australia, islands and North America1

Laman utama

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 yang ia makan?

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

Kuasa bisa

Gigitan

Bisa keluar melalui taring atau giginya apabila ia menggigit.

Apa kesan 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

Berapa bahaya ia kepada manusia?

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