Ant Problem

Hi Mommies. How do you kill ants in your home/baby's nursery? Biglang dumami yung ants sa house namin after I brought my newborn home from the hospital. Idk kung dahil sa weather or attracted lang talaga yung ants sa milk. Anyway, hope maka suggest po kayo ng safe way to get rid of them. Na papraning kasi ako every time I see one. Thank you!
