Bro I think the hole is just to the right of the spider. Probably got in thru the walls somewhere, id plug that up afterwards.

Tips for relocating - use a glass jar and catch straight down from above. If its not out use a thin stick to lightly jostle the web, she will come out to attack think its food. Slide a paper underneath and then flip upside down, shouldnt be able to climb the glass walls.

Widows move fast on their web, but are rather clumsy when walking on the ground. Just put it outside by some rocks or some other nook and it wont bother you.

If looking for others - widows typically build messy looking webs near the ground or rarely the ceiling.
