Does anyone know what type of young spider has two orange spots on it's underside?

Question

I live in Florida and outside of my house there are small little dark grey to black spiders that have two dark orange-y spots (they look like they're side to side but I don't think they're connected) and I don't know what sort of spider they are and if they're venomous, and I'd rather not stick my hand in their webs to find out. Does anyone know what they are?
