As the museum article points out: “The female Cupboard Spider could easily be mistaken for a Redback Spider, but lacks the distinctive red stripe on the back. Both spiders are from the same family, Theridiidae (also known as comb-footed spiders), so they are closely related. However, the Cupboard Spider is not considered as dangerous as its Redback relative.”
It also goes on to say: “Bites from Steatoda species occur infrequently. In the past they have not been considered particularly dangerous to humans, however in a few recent cases of Steatoda bites where the spider has been identified, more serious symptoms have been recorded. In two cases, Redback antivenom has been used successfully to treat these symptoms.”
