How To Use Diatomaceous Earth To Kill Bed Bugs?

Before you use the diatomaceous earth, you need to seal proof of your home for two reasons, i.e., to make sure you kill all the bugs and prevent re-entry. You need to clean your home thoroughly by vacuuming and steaming. Then wash the infested fabrics. After cleaning and sealing all cracks, you can proceed to the process.

Application of DE is simple; you just need to sprinkle it around using the duster or any other tool that makes fine sprinkling possible. Carefully line the edges and places where the bugs live and move. Even load DE in electrical outlets and electrical appliances.

You can leave out DE for as long as you want, and it is effective till it gets wet. It is recommended to wait till the bed bugs complete a cycle. Vacuum it out using a fine filter vacuum, or you can simply wipe it out.


1. Does Diatomaceous Earth Kill Bed Bugs?

Diatomaceous earth kills bed bugs but not in the conventional way of other pesticides do. It does not affect it internally but disrupts its exoskeleton physically.

When the bed bug comes in contact with DE, the silica present in this powder attaches to the bug externally as it is superfine. Due to the dehydrating nature of silica, the shell dries up, leaving the bed bug vulnerable soon after it dies as it has no protection.

2. How Long Does It Take For D.E. To Kill Bed Bugs?

There are two phases to happen after you sprinkle DE all over the place. Firstly, the bug must come in contact with the powder. Therefore, make sure you sprinkle it in the most critical places where bugs move around is the key.

Secondly, after the bug comes in contact with DE, it needs to dry out and then die in about 4 hours but not instantaneous like in other pesticides. Meaning it takes anywhere from a day to a week for bed bugs to die.

3. Can I Use Diatomaceous Earth On The Bed?

Using it on the bed is harmless, however, as it is fine-textured and hence hard to get it out of the fabric. So, it is better to use it away from the mattress and bedsheets. The best way is to create a perimeter around the bed rather than using it on the bed directly.

4. Does It Kill Bed Bug Nymphs?

Yes, it kills bugs in all stages; however, they need to come in contact with diatomaceous earth. Even nymphs are killed similar to the adults once they touch the DE. You must make sure that the DE is away from moisture for it to be effective.

5. Is Diatomaceous Earth Safe?

There are two types of diatomaceous earth, food-grade, and pool grade. Pool grade DE is primarily used in filtration and contain toxins like arsenic and lead. Food-grade DE is safe for consumption as it does not contain harmful components.

Therefore, it’s advisable to choose food-grade diatomaceous earth if you’re to use it for killing bed bugs in your home.

The only precaution you need to take is not to inhale it directly as it is a fine powder and affects your lungs, similar to any other fine dust. To be safe, wear a dust mask when you’re sprinkling diatomaceous earth.


Diatomaceous earth is one of the safest and effective ways to kill bed bugs. If you’re using food grade DE by Harris or any in the list, you can set up a perimeter of protection that keeps you away from the bugs.
