Dear Jose and Konstantinos, Thank you so much for the information and insight. Just to add to the information, that after termite treatment at my home, ant infestation of my home and in my terrace garden also ceased completely, and subsequently the infestation of these scale insects. They have died out completely without any treatment (termite treatment was done inside the house and garden is on terrace adjacent to rooms). How ever thanks as this understanding has come only after I was informed by you that the insects are Coccidae.
