2Diatomaceous Earth
Diatomaceous earth is a naturally occurring sedimentary rock that can be easily crumbled into an off-white powder. Made from diatoms, it can be an effective way to prevent bed bugs in your household. Although it looks like a powder, bed bugs often see them as shattered glass. Keep in mind that diatomaceous earth cannot kill insects, but it can keep them out safely. Pesticide-grade products are safe for animals and humans. However, you should avoid breathing in or eating it. Avoid food- or pool-grade diatomaceous earth because the grains can be too fine and harmful for your health. [2]
