The cupboard spider is a common house spider that lives in dark corners and builds messy, three-dimensional webs. It is often mistaken for the dangerous black widow, but its bite is usually minor. Its name shows that it is found in many parts of the world, including Europe, temperate Asia and areas where it has been introduced.1

Com reconèixer-lo

Adult females are 6 to 10.5 mm long, dark coloured and round-bodied, with a bulbous abdomen.1
Typical colour ranges from purplish brown to black, with light-coloured markings.1
It has no bright red hourglass pattern or other bright, distinctive markings.1
Males are thinner and can be nearly as long as females, at 4.1 to 10 mm.1
Sexually mature males have lighter, more reddish legs than females.1

Sovint es confon amb: It is often confused with black widows and redbacks (Latrodectus species), which have a bright red hourglass pattern that this spider lacks. Steatoda borealis is similar in shape but slightly smaller and found in colder climates. It has coloured markings on the top of the abdomen rather than the underside.1

The bite is minor in humans and has no long-lasting effects. Symptoms can include blistering at the bite site and pain. A few cases have included fever, nausea, sweating and a general feeling of being unwell that lasted several days.1

The spider is not aggressive. Most injuries to people happen when a spider is accidentally squeezed or pinched and bites in defence. It is possible that a spider may bite a finger pushed into its web by mistake.1

Bona notícia: els metges tenen un medicament (l'antiverí) o un tractament per a això.1

Què fa quan té por?

It usually flees when a large creature comes near, and it bites when it is squeezed or pinched.1

Estigues segur

No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
Si te'n mossega un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.

Dades

Director Sam Raimi chose this spider to play the radioactive spider that bites Peter Parker in the 2002 film Spider-Man. The filming spider was painted with red and blue makeup.1

The spider reportedly preys on black widows, which can make it useful to have around.1

It can go several months without feeding, as long as it has access to water.1

Females can live up to six years, while males typically live 1 to 1.5 years and often die shortly after mating.1

Desmuntamites

Mite: It is a dangerous widow spider, just like the black widow.

Veritat: Its bite is minor in humans and has no long-lasting effects, although it can cause pain, blistering and, in a few cases, several days of feeling unwell.1
