You may be wondering, “Why does diatomaceous earth kill bed bugs?” It’s an easy way to get rid of bed bugs. It works by trapping the bugs in a small, dry layer. If you’re using diatomaceous earth as a powder, place a small pile around the bed, bedside table, or other areas where the bugs might be hiding. Make sure the diatomaceous earth is dry before you apply it.
Diatomaceous earth is an eco-friendly alternative to all other bed bug repellents. It works by deterring the bugs from laying eggs in your bed. However, it is not effective for eliminating a whole bed bug infestation in a matter of days. The reason is that bed bugs are attracted to heat, CO2, and the smell of people.
Diatomaceous earth is composed of small, hollow cylinders that are highly abrasive. The tiny particles scratch the insects and cause them to die. Because of this, the bugs cannot develop an immunity to diatomaceous earth. And since diatomaceous earth is a mineral, it will stay where it is applied. Therefore, sweeping up dead bed bugs will not affect the effectiveness of this method.
Another factor that makes diatomaceous earth effective is its ability to kill bugs in a dry environment. It won’t work effectively when applied outside or on humid surfaces. If you want to use diatomaceous earth as an outdoor bed bug spray, you will need to spray the area after it has dried. However, diatomaceous earth can be applied both indoors and outdoors. In a dry environment, diatomaceous earth will be more effective and last longer.
