Explanation

Insecto is a diatomaceous earth product isolated from diatoms and is used to control the insects, which have their soft body parts exposed but covered by a waxy film to prevent dehydration. When they came in contact with diatoms in Insecto, the silica frustule break the waxy film on the insects causing them to dehydrate and die.
