Square clones not being removed outside of the screen?

Question

C++ / C#

Hello.
Is it possible to kill clones when they are off screen?
I have objects and it loads the application very much: it starts to freeze and the movement slows down.
Please tell me how to fix this problem? I've been trying for a long time and can't figure it out...

www.unity3d.ru/distribution/viewtopic.php?f=18&t=5601 here about removing everything that the player can't see. If your objects are moving, then you can simply delete them when they are far enough away. or after a certain time
