How do I my get kids to stop unfolding laundry and throwing toys all over the room?

I have 3 boys and they do not care how hard I try to keep their rooms and the house looking nice. They throw toys and do not even play with them right. I just do not get it. When I was a kid a car rolled on the floor it was not used to see who can make the biggest whole in the wall. Well most of their toys toys have now been taken away cause of this and the fact that they will not clean up no matter what is said or done.
Also I will wash their clothes but they keep taking the clothes off the shelves and throwing them all around the room. If I am not on top of it they will take off their dirty clothes and mix it with everything. I do not have any other help with this issue in my house I seem to be the only one who cares as I do not recall my husband saying much about this ever. I am at my wits end and I need anyone’s help.
I have been thinking about getting some trunks for toys and clothes and putting locks on them in their rooms. What would you do. I feel like pulling my hair out.
