Bed Bug Powder
Bed bug “dusts” can penetrate into voids and cracks and crevices to get to the bed bugs
There is no magical bed bug powder to control bed bugs. Any such powder should be combined with IPM principles; however there are dusts which have a valuable role in controlling this pest. Any dust to be considered must be registered with the US Environmental Protection Agency (USEPA) or in Canada, the Pest Management Regulatory Agency (PMRA). If it is a natural dust, it might be exempt from registration depending on the product and regulations.
The powders are typically called “dusts” and include natural and synthetic products. These include diatomaceous earth, pulverized diatoms or skeletons of very small animals found in the ocean and even some other natural dusts. Most commonly used, though, are synthetic dusts. These are small particulates which can penetrate into voids and cracks and crevices to get to the bed bugs. The advantage of dusts over liquids, as an example, is that the dusts penetrate into areas not accessible to liquids and the fact that the dust stays accessible and effective to the bed bugs for some time. So even if there is no exposure to the bed bugs when treated, the dust remains and if bed bugs wander into treated areas, they can be controlled. In addition, dusts can be used in areas that might not be appropriate for liquids such as in electrical outlets.
Few people prefer to have the bed treated; however, in most situations, dusts can penetrate into box springs and other tight areas more readily than liquids.
