Diatomaceous earth is a natural, non-toxic substance that can be used to get rid of pests in your home and garden.
It's made up of the fossilized remains of tiny aquatic organisms called diatoms, which are rich in silica.
Diatomaceous earth works by dehydrating and killing pests, not by poisoning them.
This makes it a safe option for households with pets or children.
It's also a long-lasting solution, as it can be reused multiple times.
What is Diatomaceous Earth?
Diatomaceous earth is an all-natural pest product approved for organic gardens.
It's made from fossilized marine organisms, which is pretty cool.
You can find it in a fine, white powder form, similar to talcum powder.
This powder is a main ingredient in many products, including toothpaste and skincare products.
It's also used in some foods and beverages.
One of its primary uses is for garden pest control.
How to Use Diatomaceous Earth
To use diatomaceous earth effectively, it's essential to understand its limitations and applications. Diatomaceous earth only works when it stays dry, so moisture control is crucial outdoors.
Rain or morning dew can reduce its effectiveness, so apply it in areas that are sheltered from the elements. This means applying it to the perimeter of your patio or garden, paying special attention to cracks and crevices in your walkways or patio.
You can also apply it directly on plants to help control garden pests, but be sure to use it sparingly and in areas where it won't be disturbed. This will help prevent dust inhalation risks and ensure the powder stays effective.
For indoor use, apply thin layers behind appliances, under sinks and furniture, and along baseboards and in cracks and crevices. This will help target crawling pests and prevent them from traveling through the area.
When applying diatomaceous earth, use a bulb duster to get it deep into cracks and crevices, and place it behind electrical face plates and light switches. You can also use it to rub into carpets and mattresses, but be sure to vacuum it up afterward to avoid it being blown or moved around too much.
Here are some specific areas to focus on when using diatomaceous earth:
- Perimeter of the patio or garden
- Cracks and crevices in walkways or patio
- Behind appliances
- Under sinks and furniture
- Along baseboards and in cracks and crevices
- Carpet areas (lightly sprinkle and leave for a few hours before vacuuming)
Remember to use diatomaceous earth strategically and safely, and always follow the manufacturer's application instructions for safety.
Pest Control and Safety
Diatomaceous earth is a natural and effective way to control pests, but it's essential to use it safely and correctly. Always choose food-grade diatomaceous earth, as industrial-grade can be harmful if inhaled.
Protect your skin when applying diatomaceous earth by using personal protective equipment, such as dust masks and gloves. Follow the instructions on the product label, as different products may have varying usage guidelines.
To avoid inhaling the dust, don't breathe in the powder, even food-grade diatomaceous earth, as prolonged exposure can irritate the lungs. Store unused diatomaceous earth in an airtight container to maintain its effectiveness.
Here are some key safety precautions to keep in mind:
- Protect your skin and avoid inhaling the dust.
- Follow the instructions on the product label.
- Store unused diatomaceous earth in an airtight container.
- Keep children and pets out of treated areas until cleanup is complete.
- Reapply diatomaceous earth after rain or heavy dew, as it loses effectiveness when wet.
Pests for Pest Control
Diatomaceous earth is a versatile pest control tool that can help control a wide range of crawling pests. It works by physically damaging the exoskeleton of insects, making it effective against many common household pests.
Here are some of the specific pests that diatomaceous earth can help control:
- Ants
- Bed bugs
- Cockroaches
- Fleas
- Ticks
- Silverfish
- Earwigs
- Slugs
- Beetles
It's worth noting that diatomaceous earth is not effective against flying pests or rodents, so it's essential to consider other control methods for these types of pests.
To get the most out of diatomaceous earth, it's best to apply it as a dry powder or mix it with water and apply it with a sprayer to hard-to-reach spots.

Best Practices and Safety Precautions
When using diatomaceous earth for pest control, it's crucial to choose the right grade. Always select food-grade diatomaceous earth, as it's safe for use around pets and people when applied correctly.
Industrial-grade diatomaceous earth is harmful if inhaled, so it's essential to avoid using it altogether. Pool-grade diatomaceous earth has been heat-treated and can be hazardous to your lungs and skin, so it's not suitable for pest control either.
To protect your skin, use personal protective equipment like dust masks and gloves when applying diatomaceous earth. This will prevent any potential irritation or harm.
Follow the instructions on the product label carefully, as different products may have varying usage guidelines. There are over 160 pest control products that utilize diatomaceous earth, so make sure to consult the label for specific instructions.
A thin layer of diatomaceous earth is all you need to deter pests. Avoid piling it up, as this can actually deter pests from walking through it.

Diatomaceous earth loses its effectiveness when wet, so reapply it after rain or heavy dew. This will ensure it continues to work effectively in controlling pests.
If you're using a vacuum to clean up diatomaceous earth, check the instructions first to ensure it can handle the fine particles. Some vacuum cleaners may blow the dust everywhere, so use a damp rag for cleaning indoors if necessary.
To keep children and pets safe, keep them out of treated areas until cleanup is complete. Food-grade diatomaceous earth is considered generally safe for use around pets and people when used properly.
Remember to store unused diatomaceous earth in an airtight container to maintain its effectiveness. This will help you get the most out of your product and ensure it remains safe to use.

Choosing and Applying Diatomaceous Earth
To get the most out of diatomaceous earth, you'll want to choose the right applicator for the job. A DE applicator will give you more precise results than applying it by hand.
You can apply DE as a dry powder or mix it with water and spray it on hard-to-reach spots. However, keep in mind that DE only works when it's dry, so avoid using it when it's wet.
Here are some steps to follow when applying DE:
- Create a ring of DE around plants to keep pests away.
- Spread DE in light layers around plants and only lightly dust leaves so they can still absorb sunlight.
- Reapply DE after watering or rainfall, as heavy rains can wash it away.
Which DE to Buy?
When purchasing diatomaceous earth, ensure you're working with food-grade diatomaceous earth, as "pool grade" or "crystalline silica" DE isn't safe for garden use.
To avoid any confusion, look for the label "food-grade" or "100% natural" when shopping for DE. This will guarantee that you're getting a safe and effective product for your garden.
