Diatomaceous earth is a popular natural solution for pest control, but will it actually work for you? It's made from the fossilized remains of tiny aquatic organisms called diatoms, which are rich in silica.

This powder is incredibly fine and can be easily breathed in, so be sure to wear a mask when applying it. Diatomaceous earth works by dehydrating pests, causing them to die from water loss.

It's highly effective against crawling insects like ants, bed bugs, and cockroaches. In fact, it can be used to kill these pests in a matter of hours.

What Is Diatomaceous Earth?

Diatomaceous earth, or DE for short, is the fossilized remains of single-cell microalgae that exist naturally in the soil and many bodies of water.

These tiny algae, called diatoms, have cell walls or shells constructed from silica that takes a form much like glass. Their sharp edges are capable of cutting into some small bugs.

Diatoms die and remain on the earth, where they're collected to create diatomaceous earth.

How It Works

Diatomaceous earth works by cutting through the outer layer of an insect's exoskeleton, causing them to dehydrate and die.

The microscopic edges of the fossilized diatoms in DE are what make it scratchy, which is why it irritates the skin and eyes.

This scratchiness is also what allows DE to effectively kill bugs, even those with hard shells on the outside.

The sharp particles in DE cause the outer waxy layer of an insect's exoskeleton to break down, leading to dehydration and death.

This mechanical action is what sets DE apart from chemical pesticides, which disrupt biological functions in a targeted manner.

DE doesn't introduce toxic substances into the environment, making it a safer choice for pest control.

However, when used in environments where bacteria are present, DE can still have an effect, although its impact on beneficial microbes is still being studied.

Uses and Effectiveness

Diatomaceous earth has been studied for its potential health benefits, including lowering blood cholesterol concentrations. In a study published in the European Journal of Medical Research, researchers found that diatomaceous earth reduced blood cholesterol levels in participants.

Diatomaceous earth can be used to treat fleas, but it's not a substitute for regular flea preventatives recommended by veterinarians.

For indoor flea control, dust the affected areas with diatomaceous earth using an applicator or a sock filled with the product.

You'll want to let the DE penetrate the areas for an hour or more before vacuuming it up, and repeat this process daily for maximum flea control.

It's essential to use caution when applying diatomaceous earth, as it can cause irritation to a dog's eyes, airways, and skin.

To avoid this, make sure the areas you're treating are completely dry and well-ventilated, and keep family and pets away during the treatment process.

Diatomaceous earth does not work on flea eggs, so it's not a foolproof solution for getting rid of all fleas in the environment.

Using It in the Garden

Using DE in the garden is a game-changer for pest control. DE is effective against a wide range of garden pests, including slugs and tomato hornworms.

Sprinkle DE at the base of plants or use it to create a barrier that pests won't cross. This can help protect against beetles by dusting the leaves of plants with visible signs of damage.

If it rains, you'll need to reapply DE. Unfortunately, DE will kill all insects with exoskeletons, so be extra cautious when applying and focus on single plants showing signs of pest damage.

Safety and Precautions

Diatomaceous earth is a natural and non-toxic substance, but it's still important to use it safely.

To avoid skin irritation and drying, don't apply diatomaceous earth products directly to your pet's skin or on their bedding.

You should also be careful not to inhale the dust, as it can cause sneezing, coughing, and even difficulty breathing in large amounts.

If you have asthma or lung issues, use caution when applying diatomaceous earth, as it can be irritating to those with respiratory problems.

To use diatomaceous earth safely, make sure to wear gloves and a mask to avoid skin contact and inhalation of the dust.

If you're using diatomaceous earth in your yard or around your home, keep pets away from the area until the dust settles.

Here are some guidelines to follow when using diatomaceous earth safely:

  • Wear a mask when applying DE powders or dust.
  • Run an air purifier in the room while DE is in place.
  • Avoid breathing in large quantities of DE.
  • Wear gloves to avoid skin contact with DE.

Remember, food-grade diatomaceous earth is the safest option for use around humans and pets, and should be used in accordance with the manufacturer's instructions.

Pest Control Methods

Diatomaceous earth is a versatile and effective pest control method that can be used in various ways. It works by dehydrating insects with an exoskeleton, causing them to dry out and die.

To use diatomaceous earth for pest control, you need to apply it directly to the surfaces where pests are crawling. This can be done using an applicator or a sock filled with the product. It's essential to let the DE penetrate the areas for at least an hour before vacuuming it up. Daily vacuuming is recommended for maximum flea control.

Diatomaceous earth is effective against a wide range of pests, including cockroaches, bed bugs, fleas, ticks, spiders, and more. However, it's not recommended for use on pets specifically, as it can cause irritation to their skin, eyes, and airways.

If you're dealing with a flea infestation, diatomaceous earth can be used to control the problem, but it's essential to note that it doesn't work on flea eggs and therefore doesn't treat the flea's entire life cycle. This means that multiple applications may be necessary to fully get rid of all fleas in the environment.

Here's a list of some of the pests that diatomaceous earth can kill:

  • Cockroaches
  • Bed bugs
  • Fleas
  • Ticks
  • Spiders
  • Mites
  • Lice
  • Silverfish
  • Ants
  • Millipedes
  • Centipedes
  • Earwigs
  • Crickets
  • Flies
  • Stink bugs
  • Aphids
  • Thrips
  • Grubs
  • Beetles (some varieties)

It's essential to note that diatomaceous earth can be drying to skin and may irritate eyes and nasal passages, so it's crucial to use it cautiously and consult with a veterinarian before using it on pets.

Types and Grades

When choosing diatomaceous earth for pest control, it's essential to understand the different types and grades available. The primary types of DE you may see in stores or online include those designed for safe use near humans and pets, as well as others with other intended uses.

Some DE products are labeled as "Food-Grade", which is the safest option for pest control around your home or business. Food-grade DE must contain less than 1% crystalline silica.

Types of

Types of diatomaceous earth are crucial to consider before use, especially in living spaces. Some types are designed for safe use near humans and pets.

You'll often find three primary types of DE in stores or online: these include food-grade, pool-grade, and non-food-grade DE.

Food-grade DE is the safest option for use around humans and pets, but it's not always the most effective for pest control.

Pool-grade DE is used to filter pool water, but it may not be suitable for use in living spaces due to processing.

Non-food-grade DE has other intended uses, but it's not effective for pest control due to processing.

Feed Grade DE

Feed Grade DE is a type of diatomaceous earth that's intended only for feeding animals. It's not suitable for use around living spaces due to lower safety standards.

You should still look for food-grade products when applying anywhere near your living or working space, even if you're using feed-grade DE for animal feed.

Feed-grade DE has different testing and safety standards than food-grade DE, which means it's not as safe for use around humans and pets.

I've used feed-grade DE to treat my cat for worms, and it works well. However, it's not always white, and I believe it's processed to make it white for aesthetic purposes.

Here are some key differences between food-grade and feed-grade DE:

It's essential to check with your vet before feeding DE to your pet, as what's good for one pet might be bad for another.

Potential Dangers and Precautions

Diatomaceous earth is a natural resource that's generally safer than chemical-based bug sprays and powders. However, it still contains a lot of silica.

Silica dust can be unhealthy if inhaled in large quantities or over a long period of time.

To use diatomaceous earth safely, it's essential to take precautions against inhaling the silica dust. This can be done by wearing a mask when applying it.
