Ants lived my home in last year. Rhey make many problem. But main problem is that they make hole everywhere in my house. For example, they make hole in wall, wall clock, plants, food. The holes look like black dots. That spoiled home decoration. Hole would be home for new ant. They spreaded quickly around hole. Also, their hole killed other living. For example, my mother like to growing plants like orchid. Because ant graw at their root and leaves, they were dying when my mother found them. So, my family were careful about putting food in kitchen.
