How to apply diatomaceous earth effectively for bed bugs?

To apply diatomaceous earth for bed bugs, first, make sure the area is dry. Sprinkle a thin layer of diatomaceous earth around the bed frame, headboard, and other areas where bed bugs may hide. Reapply the powder every few days and leave it for at least a week to effectively kill the bed bugs. Vacuum the area thoroughly after a week to remove the powder and dead bugs.
