Play ParticleSystem on RayCastHit Object

I have a GameObject with a Particle System component on it (this is an enemy).

I have attached a blood Particle Effect to enemy so when I hit the enemy, the blood will show.

How can I play the Particle System on an object I hit with RayCastHit?

I have tried everything I can think of over the past hour or 2, no luck:

if(Physics.Linecast(playertarget.transform.position, attackrange.transform.position, out hit)){
    if(hit.transform){
        hit.transform.particleSystem.Play();

Thanks robertbu for the help.

I ended up going with this:

if (hit.transform.Find("Blood")){
hit.transform.Find("Blood").particleSystem.Play();
}
