Still have that diatomaceous earth handy from when you isolated you bed? Now is the time to use it. It will provide residual killing power on any bed bugs that might be left after you cleaned your bedroom.

Note: Your bed bug exterminator may have a different dust that he wishes to use as a residual killer. Discuss it with him before putting the DE down.

 Diatomaceous earth is a natural treatment for bed bugs.  It consists of the fossilized remains of tiny sea creatures, and while it is safe for humans, it is deadly to bed bugs.  As you can read by the user reviews of this product listing at Amazon, DE can be really effective.

Put the DE along the baseboards, in the cracks between the planks of the hardwood floor, around the closet, around any furniture, as well as inside any electrical sockets or light switches. You can also put it under the cushions in any upholstered furniture.

Don’t put DE in high traffic areas or areas where it is likely to be disturbed. It is a very light powder, after all, and even the breeze created by walking past it may disturb it.
