Is having kids ages 2-4-6 in a house with black mold and the kids are constantly sick running noses and all what should be done

I lived in a house with black mold. My children had to see a allergist to get it documented. Ince it was on paper I called the environmental people and they investigated and made my landlord pay for the allergist and the removal of the mold. There is a spray you can get to get rid of it. If it's your house wash with bleach and use kills to paint over it. Good luck and please act quickly for the kids sake

She moved out one month after. We found mold it's all behind the walls and all so she just left and took the eviction just to get her kids out but thank y'all for the comments

Get rid of the black mold use bleach and ammonia don't mix the two, "Please"... And get the kids looked at medically...
