Destroy the Particle Object attached a Sprite

I want to destroy the particles when the bullet strikes the wall.

I do not know how.

the object always remains displayed particle

if you placed "particle destroy" destroys all the objects that exist particles

Step1: put the particles and the bullet_1 object in a container [groups->container]

Step2: delete this line

-> bullet_1: Spawn object Particles on layer 1 (image point 0)

Step3: forget about these sharing sites, and install dropbox.

Is there another way to make the particles are destroyed 3 seconds after the object ball?

present when the bullet is also destroys the particles are destroyed and is unrealistic.

thanks
