How should diatomaceous earth be applied to effectively eliminate bed bugs?

To effectively eliminate bed bugs using diatomaceous earth, it should be applied in a thin layer in areas where bed bugs are present, such as along baseboards, under furniture, and around the bed frame. The diatomaceous earth works by dehydrating and killing the bed bugs. It is important to reapply the diatomaceous earth as needed and to follow the manufacturer's instructions for safe and effective use.
