Flickering point lights blender cycles

Hey guys, for some reason the point lights in the house are flickering at the beginning of my animation. I thought at first it was my particle system colliding with them and/ or casting shadows but I made the house a collision object that kills particles and used light linking groups so that point lights only affect everything except the particles and lastly I turned of shadows - however the issue still isn't resolved. Any ideas?
