The black-footed yellow sac spider is a small, pale yellow spider native to the Americas. It hunts at night and does not spin webs to catch food. It sometimes lives in homes, but its bites rarely cause more than local symptoms.1

Wat eet dit?

It feeds on a variety of arthropods, such as insects and other spiders. It does not use webs to catch prey. Instead, it actively hunts, detecting prey mainly through vibrations in the surface it sits on, and it can catch airborne prey while hanging from a silk line.1

As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

It hunts at night and builds a new small silk nest every day, in under 10 minutes.1

It can spread to new trees and shrubs by releasing a long silk thread that the wind carries, or by ballooning through the air on a silk line.1

It does not spin a web to catch prey. It hunts actively instead.1

Females mate only once and produce their first egg mass about 14 days after mating.1

Mite-breker

Mite: Cheiracanthium bites cause necrosis, the death of skin and tissue.

Waarheid: Bites cause only localised swelling.1
