These spiders are all over my house mainly in my basement I just want to know if they are poisonous or not
Hi, welcome to Spider ID. 🙂 This is a Long-bodied Cellar Spider, Pholcus phalangioides. Like most spiders they have venom but are not considered to be of medicial significance (everyone’s immune system is different though). They aren’t anything to worry over and are adept at catching less desirable bugs much larger than themselves.
