Hi. your little friend is a female Steatoda triangulosa, one of he innocuous household cobweb spiders.
She has been a busy gal.
Welcome to the site.
Thank You Bugman Dan! Our home flooded during the Great Flood of August 2016 (we got nearly 4 1/2 feet of water). It took us over year to rebuild & ever since we moved back in we’ve had all kinds of spiders/bugs. I’m glad I found this website & will be sure to post more pics as I run across more spiders.
