What's the best way to stop particles?

So, I have a pretty simple problem but it's been a while since I used Unity. I have a 3D house placed on a terrain during a rainstorm particles. My problem is simple: some of the rain particles are somehow leaking inside the house even if it has its own Mesh Collider.

I remember I used to do Component -> Effects -> World Particle Colliders (and I can't remember if I had to add that on the particles or on the house mesh) but I noticed that now this component is under "Legacy particles" which makes me suspect there's a better way.

Sorry if the question isn't clear enough...
