What kind of spiders are these and what should I do to get them out of my house?

Yesterday, I was looking at one of my house plants and it was covered with yellow specks. At first I thought it was pollen, but after taking a closer look, I realized that it was baby spiders and they were covering the entire plant! I threw the plant outside and sprayed everything around it with furniture polish and windex. I don't know where the mom spider is though and I want to make sure that all the spiders are gone. What should I do? Does anyone know what kind of spiders they are? Thanks!
