Insect powder

Saturday, 6 April 2013

Insect powder (made from volcanic soil) works primarily by its ability to absorb oil. It destroys the wax layer which protects the insects from drying out, and they die due to water loss. Insect powder and other kinds of fine-grained mineral soil was used for disinsectisation since ancient times. The ancient Romans mixed fine road dust in the grain, which was supposed to be stored. One should try to be careful not to inhale the powder or getting the powder in the eyes.
