Steatoda triangulosa I believe.Quite harmless
I don’t know which it is with enough certainly either. There are many Steatoda species that can be in California plus Asagena species. Our website is one of the top results in Google Lens image searches and I don’t want to put content based on educated guesses out as if it was definite. I don’t want to add to the “expert” junk info. MK, the “quite harmless” part is something we’re sure of.
