The phrase encapsulates the process of utilizing a naturally occurring siliceous sedimentary rock, in a powdered form, to manage infestations of parasitic insects that commonly infest bedding and dwelling spaces. This process involves strategically distributing the fine powder in areas where these insects are likely to travel or reside, creating a barrier that compromises their exoskeletons and leads to dehydration.
Effective implementation of this method can contribute to a more sustainable and less chemically intensive approach to pest control. The substance presents a lower toxicity risk to humans and pets compared to many synthetic insecticides, making it a viable option for households seeking environmentally conscious solutions. Its historical use in agriculture and pest management demonstrates its enduring relevance in addressing unwanted insect populations.
