It has arrow on its back
Found Spider- Large, Orange With One Arrow Like Stripe Down Middle Of Back. Large Web Between Medium Size Scrubs. What Would It Be?
It sounds like it could be an Orb Weaver Spider, they are usually the same color you specified, large and can have a stripe or more along their bodies. I would google it if it worries you and if you see any more around the house. Although Orb Weavers are garden spiders and usually aren't found indoors. Good Luck!
This is a Garden Orb Weaver spider if it is found on medium-sized shrubs, you don't need to worry because they are not poisonous, they just cause minor skin irritation. When web is touched at night, the spider will jump into the middle of the web.
