Diatomaceous Earth INS is a fantastic organic insecticide. Diatomaceous Earth INS is made from 100 % Natural Fresh water Diatomaceous Earth. Diatomaceous Earth as it's known, was used very effectively for about one hundred years before chemical pesticides were introduced. Since chemical pesticides tend to leave residue in our food supply and poison the heck out of mammals, bees, fish and any wildlife they come in contact with, Diatomaceous Earth is back in fashion in agricultural circles as it does not contain any toxic chemical. How it works For Bed bugs you spread a newspaper on Bed (Wooden Surface) and sprinkle some powder on it (For this you can use any old talcum powder container) and then again put one more newspaper on it and then mattress. Keep this powder for 10 days and then replace it. Also in corner openings of wooden part of bed you can apply some powder. If you have bed bugs in switch box and behind tube light you can apply on that. In kitchen also just sprinkle in drawers using newspaper and near wall of cupboard and allow to remain for long time. As this is completely organic product and does not have any chemical and kills insects and pests mechanically by scratching their outer shell and absorbing there fluid and dehydrating them it will take time to get completely rid of them. In 2-3 days only bed bugs will stop biting and slowly none will be visible. In Kitchen continuous use will clear cockroaches also. This is the only insecticide which you can eat also and nothing will happen rather it will be beneficial. Do not inhale it as any dust inhaled causes irritation and it should not go in eyes else it will cause irritation. If you have pets at home then you can apply the powder on their skin and keep it for 2 days and then bath them. Pets will get rid of ticks.
