Why is one part properly being destroyed but the other isn't?

I have a script that creates two Instance.new parts named "Zap" and "Zap2". These two will destroy themselves immediately if they hit another player but if they don't then they are supposed to just be destroyed five seconds later. I was able to manage to get the first Zap to destroy on it's own after five seconds, but the second one won't destroy on it's own it will just wait for it to come in contact with another player. This is really confusing me so please help.

Zap.Touched:Connect(function(Hit)
    local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
       if Humanoid == nil then return end
         if AlreadyTouched == false then
            AlreadyTouched = true
            if Humanoid.Parent == Character then
             AlreadyTouched = false
             print("Local Humanoid Touched")
             Humanoid.Health = Humanoid.Health - 0
       else
             if deb == true then return end
             deb = true
             print("Humanoid Touched")
             Humanoid.Health = Humanoid.Health - 30
             Zap:Destroy()  --Works
       end
       wait(5)
       deb = false
       Zap:Destroy()  --Works
      end
  end)

Zap2.Touched:Connect(function(Hit)
 local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
   if Humanoid == nil then return end
    if AlreadyTouched2 == false then
     AlreadyTouched2 = true
     if Humanoid.Parent == Character then
      AlreadyTouched2 = false
      print("Local Humanoid Touched")
      Humanoid.Health = Humanoid.Health - 0
  else
      if deb2 == true then return end
      deb2 = true
      print("Humanoid Touched")
      Humanoid.Health = Humanoid.Health - 30
      Zap2:Destroy()  --Works
   end
   wait(5)
   deb2 = false
   Zap2:Destroy()     --Doesn't Work
  end
end)
wait(0.2)
Debounce = false
end)
