Keep particles to defined area, destroy on collision

I'm trying to create some particles that are obtained in an area and I think the best way to do this is creating a collider on a few cubes and turn off the mesh render. Now, is there a way that I can have these particles (not the whole system, but individual particles) delete themselves when they come into contact with the colliders? C# script would be best. I am using Unity's Standard Assets particles.
