1. How it Works 

Diatomaceous Earth (DE) is a naturally occurring, soft, siliceous sedimentary rock that is crumbled into a fine white to off-white powder. It is composed of the fossilized remains of diatoms, which are tiny, aquatic organisms with hard shells made of silica. When these diatoms die, their skeletal remains accumulate to form DE. 

The sharp, microscopic edges of DE particles are abrasive to insects but harmless to humans and pets. When insects come into contact with DE, it absorbs the oils and fats from their exoskeleton, causing them to dehydrate and die. Additionally, the sharp edges of DE can create microscopic cuts in the exoskeletons of insects, further accelerating their dehydration. 

2. Usage 

Diatomaceous Earth is a versatile substance and can be used both indoors and outdoors. 

To apply, lightly and evenly sprinkle DE on areas where pests are found or are likely to frequent. This could include bed frames for bed bugs, carpets for fleas, or garden soil for slugs and snails. Since DE works mechanically rather than chemically, pests cannot develop a resistance to it. However, DE loses its effectiveness when wet, so it’s crucial to reapply after rain or watering when used outdoors. 

Always wear a mask when applying indoors to avoid inhaling the fine particles, as prolonged inhalation can be harmful. 

3. Targeting Specific Pests and Diseases 

Diatomaceous Earth is effective against a wide range of pests, including but not limited to bed bugs, fleas, ticks, cockroaches, slugs, snails, and many types of crawling insects. Its natural composition makes it a preferred choice for those looking for non-toxic pest control solutions. 

It’s essential to note that DE does not discriminate between beneficial and harmful insects. Therefore, when using it in gardens, care should be taken to minimize its impact on beneficial insects like bees and ladybugs.
