Help with PIR sesor

I’m building a motion sensing spray bottle squirter. However the servo to pull the trigger sometimes randomly fires without the PIR sensor detecting motion or its lights lighting up. I think i had it working before but now it randomly fires.

any help would be great, Thanks

#include <Servo.h>
Servo servo1;
int start = 70;
int fire = 150;
int currPos;
int pirPin = 4;


void setup(){
  servo1.attach(3);
  pinMode(pirPin, INPUT);
 Serial.begin(9600);
 servo1.write(start);
 delay(10000);
 digitalWrite(pirPin, LOW);
}

void loop(){
  if(digitalRead(pirPin) == HIGH){
   servo1.write(fire);
  delay(500);
 servo1.write(start);
 delay(2000);
  }
}

Nvm stupid mistake. i fixed it
