How to make blood splatter using projectors(or decals)

I have been spending days trying to find the proper way to do this, i simply want to spawn a projector that displays a blood splat when a particle hits the ground or a wall. I can make the projector spawn on the particle collision but it spawns hundreds of them. Here is what I have now:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class splatter : MonoBehaviour {
     
 public ParticleSystem particleHit;
 public GameObject splat;
 public List<ParticleCollisionEvent> collisionEvents;
 
     void Start()
     {
         particleHit = GetComponent<ParticleSystem>();
         collisionEvents = new List<ParticleCollisionEvent>();
     }
 
 
 
 void OnParticleCollision(GameObject other)
     {
         Debug.Log("particle HIt");
         int numCollisionEvents = particleHit.GetCollisionEvents(other, collisionEvents);
         int i = 0;
 
         while (i < numCollisionEvents)
         {
             GameObject BloodSplat = Instantiate (splat, collisionEvents[i].intersection, Quaternion.Euler(90,0,0));
             i++;
         }
 
     }
 
 }
