A black widow in my kitchen?

Tweet

I spied a spider napping in the middle of her web this morning.It was in my kitchen, in an empty take-out rice container that had been relegated to the garbage. She had a large shiny black abdomen and medium length legs The lighting was not good, so I could not see her web, nor could I see whether she had a red spot on her abdomen. Black widows are reclusive, and rarely bite humans. But I did not feel comfortable with a possible black widow among my garbage bags.I do not use gloves when I take out the garbage. I "captured" her in an empty Safeway grocery bag, rolled the top over several times, and took her to the outside dumpster. Do you have black widow spiders where you live?
