How to Use Diatomaceous Earth for Pest Control

We have 6 rescue cats with limited resources. I found that diatomaceous earth is inexpensive and very effective for fleas and all kinds of bug control. Not so good for sweet ants so we use something else for them. I feel safe using it because it is safe for pets and people. Usual bug control spray products are poisonous and some can cause cancer.

Diatomaceous Earth (DE) is a natural product that is not only eco-friendly but also economical. It’s a popular choice for organic pest control as it’s safe to use around wildlife, children, and pets ¹ ². Here’s how you can use DE for pest control in your home and garden.

What is Diatomaceous Earth?

Diatomaceous earth is the fossilized remains of diatoms, a type of algae that creates 20–50% of the world’s oxygen ². It’s rich in minerals and can be sourced from across the globe ². The best diatomaceous earth for insecticides is milled or micronized ².

How Does Diatomaceous Earth Work?

DE works by dehydrating insects’ exoskeletons ². When the DE makes direct contact with an insect’s exoskeleton, it dries them out and can kill them ². While DE can be used as a deterrent for most pests, thanks to its ability to dry up their climate, it’s especially effective for those with an exoskeleton like ants or roaches ².

How to Use Diatomaceous Earth in Your Garden

Always use food-grade diatomaceous earth, which is available from various sources ³. To apply, place it around plant stems, in furrows, or other areas on the soil surface where pests are likely to travel to reach garden plants ³. Make sure it is applied in an unbroken barrier around the plant ³.

You can also lightly sprinkle dry DE on the soil’s surface where slugs, newly emerged Japanese beetles, or other unwanted pests will come into direct contact with the dry particles ⁴. Renew after rain or heavy dew ⁴.

How to Use Diatomaceous Earth in Your Home

Apply little bits of diatomaceous earth in the crevices around your home and where bugs frequent ². DE can be an irritant, so keep it away from high-traffic areas and don’t use too much ².

Remember to exercise caution when using DE for pest control as it isn’t suited to all materials ¹ ². Avoid mixing DE with bleach or chlorine bleach products as the combination is highly toxic and shouldn’t be inhaled ¹ ².

In conclusion, diatomaceous earth is an inexpensive and eco-friendly alternative to commercial pest control products. Whether you’re protecting your garden or safeguarding your home, this natural product can help you maintain a pest-free environment while being kind to the environment.
