What You'll Learn
Diatomaceous earth is a natural insecticide
Diatomaceous earth (DE) is a natural insecticide that has been used for years to control and kill insects. It is made from the fossilized remains of tiny, aquatic organisms called diatoms. Their skeletons are made of a natural substance called silica. Over time, these organisms accumulated in the sediment of rivers, streams, lakes, and oceans, forming large deposits that are mined to create diatomaceous earth. The silica content in DE ranges from 80 to 90%, with the remaining portions consisting of other minerals and trace elements.
DE is a lightweight, porous, and abrasive material, making it useful for a variety of applications. It is also a desiccant, meaning it can be used to deplete insects' exoskeletons of moisture, leading to their dehydration and eventual death. The sharp edges of the DE particles cut through the insect's protective outer layer, causing them to lose essential body fluids. As a result, the insects become dehydrated and die.
DE can be used to kill a wide range of insects, including fleas, mites, lice, ants, millipedes, cockroaches, bed bugs, and more. It can be applied by sprinkling or dusting it on infested areas, such as countertops, floors, carpets, and furniture. It is important to use food-grade DE for insect control, as other commercial grades may contain harmful additives. While DE is considered non-toxic to humans and animals, it can be drying and irritating to the skin, eyes, and nasal passages.
DE is an effective and natural alternative to chemical-based pest control methods in homes and gardens. It is versatile and can be used both indoors and outdoors to control pests. In addition to pest control, DE is also often used as a soil amendment to improve soil structure, drainage, and water retention.
When using DE, it is important to follow the manufacturer's guidelines and safety precautions. While it poses minimal health risks to humans, inhalation of the fine particles in large amounts can potentially cause silicosis, a lung disease. Therefore, it is recommended to wear a dust mask when handling DE and to supervise children during its application due to the risk of mild irritation.

It kills insects by dehydrating them
Diatomaceous earth (DE) is a natural insecticide that can kill insects by dehydrating them. It is composed of the fossilized remains of diatoms, which are microscopic, single-celled aquatic plants with hard silica shells. The sharp edges of DE particles cut through the insect's exoskeleton and remove the waxy coating that protects it from drying out, causing the insect to lose water and eventually die. This makes it effective against a variety of pests, including cockroaches, ants, bed bugs, fleas, and spiders.
DE can be used for pest control in the home and garden. When used as a pest control measure, it is important to regularly vacuum DE to prevent pets from inhaling or ingesting it, and it should not be applied directly to their fur or skin. It can be sprinkled on infested areas such as countertops, floors, carpets, and pet bedding. A thin layer should be applied and left undisturbed for several hours or overnight, and it should be reapplied every few weeks to maintain pest control.
DE is also effective against fungus gnats, which are a common pest when growing mushrooms indoors. It can be mixed into the soil before planting or sprinkled on the surface of potted plants to kill fungus gnats in all stages of their life cycle, including eggs, larvae, and adults. However, some sources suggest that DE is ineffective against gnats once it is mixed into the substrate. It is important to use food-grade DE for insect control, as other commercial grades may contain harmful additives.
DE is a lightweight, porous, and abrasive material with a high silica content, making it useful for various applications. It is non-toxic to humans and pets when used correctly and is an effective alternative to chemical-based pest control methods. However, inhalation of fine DE particles in large amounts can potentially cause silicosis, a lung disease, so it is important to wear a dust mask when handling the product.

It is effective against fungus gnats
Diatomaceous earth (DE) is a natural insecticide that can be used to kill insects and pests. It is composed of the fossilized remains of diatoms, or microscopic, single-celled aquatic plants or algae, that possess hard outer shells made of silica. DE is a lightweight, porous, and abrasive material, making it useful for various applications, including pest control.
DE is effective against fungus gnats, which are one of the most common and damaging insects encountered when growing mushrooms indoors. These gnats can destroy a fungus crop, leaving mushrooms brown, leathery, and inedible. DE can be used to kill fungus gnats in all stages of their life cycle, including eggs, larvae, and adults. It works by dehydrating the insects and cutting through their exoskeletons with its sharp particles, removing the waxy coating that protects them from drying out.
To use DE against fungus gnats, it is recommended to mix it with water to form a paste or sprinkle it on the soil around plants where gnats are found. It can also be used to create a barrier around plants, preventing gnats from crossing. It is important to apply it evenly and reapply as needed, especially after watering plants as DE can be washed away by water. For microgreens, add a teaspoon of DE per quart of soil or sprinkle it on the soil surface at the time of seeding.
When using DE, it is important to use food-grade DE and follow safety precautions. While it is non-toxic and safe for human consumption and use in the home when used correctly, inhalation of fine particles in large amounts can potentially cause silicosis, a lung disease. Therefore, it is recommended to wear a dust mask and eye protection when handling DE, and to vacuum regularly to prevent pets from inhaling or ingesting it.

It can be used to create a barrier around plants
Diatomaceous earth (DE) is a natural, effective, and non-toxic pest control option for use in the home and garden. It is made from the fossilized remains of diatoms, microscopic sea creatures with hard silica shells. The sharp-edged particles of DE can penetrate the exoskeletons of pests, causing dehydration and death.
DE can be used to create a barrier around plants to prevent pests from crossing. To do this, sprinkle a fine layer of DE around the plants, in an unbroken barrier. It can be placed around plant stems, in furrows, or other areas on the soil surface where pests are likely to travel. It is important to apply it evenly and thinly, as pests tend to avoid thick layers of DE powder. A light dusting can also be applied to leaves, but caution should be used not to apply so much as to limit or prevent sunlight from reaching exposed leaf surfaces for photosynthesis. DE should also be kept away from flowers to avoid harming pollinators.
DE is much less effective in moist or wet environments, so it will need to be replaced after rainfall or watering plants. It can be washed away by water, so it is important to reapply it after watering plants. It should also be reapplied after strong winds.
DE is generally safe for humans and pets, but it can be irritating to the eyes, skin, and nasal passages. It is important to wear protective glasses and a dust mask when applying it. It should also be kept out of the reach of children and pets to prevent ingestion.

It is important to use food-grade diatomaceous earth for insect control
Diatomaceous earth (DE) is a naturally occurring powder made from the fossilized remains of diatoms, which are microscopic, single-celled aquatic plants with hard silica shells. It is a popular and effective tool for pest control, especially for insects. When used as an insecticide, DE works by mechanically damaging the exoskeletons of insects, dehydrating and ultimately killing them.
While DE is generally safe, it is important to use food-grade DE for insect control. Food-grade DE is the safest form for human consumption and use in the home. It has undergone strict processing to ensure low levels of contaminants, such as heavy metals, and consists primarily of amorphous silica. Industrial-grade DE, on the other hand, may contain higher amounts of contaminants and crystalline silica, which could be harmful if inhaled.
The Food and Drug Administration lists food-grade DE as "Generally Recognized as Safe" for use in various products, including food, beverages, medicines, and water filters. Food-grade DE can be safely used to combat household pests like ants, cockroaches, bed bugs, and fleas. It can be applied to infested areas, such as countertops, floors, carpets, and pet bedding.
When using DE for insect control, it is important to follow the manufacturer's guidelines and safety precautions. This includes wearing a dust mask to prevent inhalation of the fine particles, which can cause lung irritation and potentially lead to silicosis, a lung disease, if inhaled in large amounts over a long period. Children should be supervised when using DE due to their developing lungs.
By using food-grade DE, you can effectively control insects and pests in your home or garden while minimizing potential health risks to yourself, your family, and your pets.
