Diatomaceous Earth Food Grade is a natural 100 % safe non-toxic pest control product, it can be used for pets, garden, home & plants, it gets rid of ticks, fleas, ants, cockroaches, bedbugs, termites & many more.DE is a very fine off white powder and seeps into all the cracks required to eliminate pests, it is so safe that animals and children can consume it.I have heard two explanations of how diatomaceous earth works.One is that on a microscopic level, the diatomaceous earth particles are very sharp looking. These particles stick to an insect and get stuck between its exoskeleton joints. As the insect moves, it gets physically cut up.The other explanation is that diatomaceous earth sticks to the insect and somehow causes them to dry out. I think this approach involves scratching the insect’s waxy layer which then allows precious moisture within the insect to get out. So their teeny tiny bug-innards turn into teeny tiny bug-innards-jerky.
