The noble false widow is a spider that looks a lot like the black widow, which is why it has its name. It is now found in many parts of the world, including Europe, the United States and New Zealand, and it is one of the world's most invasive spiders. Its bite can be painful, so it is worth knowing what it looks like.1

I-Yurophu, I-Afrika

Sidlani?
It eats both insects and other spiders, woodlice, and small vertebrates such as pipistrelle bats and a pygmy shrew. It catches prey with an 'attack wrap', wrapping silk around the victim while it bites, and its venom quickly paralyses the prey.1

Amandla obuthi

Ukuluma

Ubuthi buphuma ngamazinyo aso obuthi noma ngamazinyo uma siluma.

Ubuthi baso benzani?

Most of its venom is made of toxins similar to those of the widow spiders, mainly alpha-latrotoxin. This toxin makes holes in nerve cells, which releases chemical messengers and blocks the signals between nerves and muscles, causing paralysis. In people, the venom is most noticeable as pain at the bite site, along with swelling, redness and fever.1

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKungaba buhlungu ngempela, kodwa cishe akukaze kube kubi kakhulu.

It is considered moderately medically significant. Most bites cause symptoms similar to a bee or wasp sting, but some can be more serious, partly because of bacteria. It is considered one of the most dangerous spiders in western Europe. Bites from males are less severe than bites from females, and the bite itself is usually painless, with pain coming from the venom.1

Uma siluma

  • Without proper treatment, a bite wound can become infected and develop into gangrene or sepsis, so medical care should be sought.1
  • Geza inxeba lokulunywa bese ubeka iphakethe leqhwa phezu kwalo ngenxa yobuhlungu. Thola usizo lwezokwelapha uma ubuhlungu bunamandla, busabalala noma umuntu ezizwa engaphilile.

  • Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
  • Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.
