TL/DR: Is this a baby Parasteatoda tepidariorum?
I've been noticing cob webs in my room in the corners of the ceiling. I have slight arachnophobia that I'm trying to get rid of, but I'm terrified of the idea of spiders crawling on me while I sleep. So, naturally I decided to catch and keep it. The spider is very tiny, so I'm not sure what to feed it and I'm not sure about air holes. ( I read spiders can go days without air. Is it true?)
