URBANNS Pest Guard uses Food Grade Diatomaceous Earth for Pest Control. Food Grade Diatomaceous Earth (FGDE) comes right from the earth. It is amorphous silica, or a loose, powdery substance that can be used in several ways. Because it is natural and contains no additives, you can feel confident using it around the home or garden. It is also known as diatomite, fossil fleur or kieselgur/kieselguhr. At home it can be used for a natural way to control various pests that infests your home, pets or garden. It can be used for taking care of bed bugs, ants, fleas, dog ticks, flies, spiders, etc. Unlike available bed bugs killer sprays in the market, the effect of FGDE stays longer when left dry acting on bedbug longer than other sprays. This bed bug powder can provide more longer term relief as it can be spread liberally across the home and left for days. Some pure varieties are also used for human consumption and in animal feed to kill worms and improve digestion.
