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

Ahabanza

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

Ku butaka, ikigereranyo cy'ugereranyije

Irya iki?

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

Uko wayimenya

A medium-sized spider with three pairs of two eyes arranged in a triangle, instead of the usual eight eyes1
A violin-shaped pattern on the front part of the body (cephalothorax)1
Adults of both sexes grow to about 7 to 7.5 cm... no, 7 to 7.5 mm long1
Its web is very thin and fragile, made of silk strands laid in a disorganised way1

Ikunze kwitiranywa na: It is nearly indistinguishable in appearance from the brown recluse spider (Loxosceles reclusa). Pest control for one can often be adapted for the other.1

Imbaraga z'ubumara

Iraruma

Ubumara busohokera mu menyo yayo y'ubumara cyangwa mu yandi menyo iyo iriye.

Ubumara bwayo bukora iki?

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

Most bites are medically insignificant, but some people are affected much more seriously. In 2024, the species was blamed for the deaths of two people in Italy.1

Ibintu by'ukuri

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
