How Does the Mechanism of Diatomaceous Earth Work on Bed Bug Physiology?

Diatomaceous earth works on bed bug physiology by disrupting their outer protective layer. Diatomaceous earth contains tiny, soft, and chalk-like sedimentary rock particles made from the fossilized remains of diatoms. These particles have sharp edges that cause physical damage when bed bugs come into contact with them.

When bed bugs walk over diatomaceous earth, the sharp edges pierce their exoskeletons. This leads to dehydration. Without moisture, bed bugs can no longer regulate their internal water balance, resulting in their death. Additionally, the powder absorbs oils and fats from their bodies, further accelerating dehydration.

This mechanism effectively targets adult bed bugs, nymphs, and even eggs, making diatomaceous earth a versatile option for pest control. Bed bugs’ inability to develop resistance to this physical method contributes to its effectiveness.

Using diatomaceous earth requires careful application in locations where bed bugs hide. Optimal areas include bed frames, carpets, and cracks in walls. Effectiveness depends on maintaining the powder’s integrity and ensuring it remains dry, as moisture renders it ineffective.

Overall, diatomaceous earth functions as a desiccant for bed bugs, leading to their eventual elimination.
