Yes. Diatomaceous earth can effectively drive away mice, rats, moles, voles, and other rodents. It is a natural way of keeping your garden or yard free from these stubborn pests. Compared to essential oils, diatomaceous earth is more efficient in warding off rodents.

Diatomaceous earth kills bugs and pests by dehydrating them to death. But it is the smell that repels mice and other rodents. It is an effective pest control substance because of its abrasive and physio-sorptive properties.

Diatomaceous earth is dust with microscopic sharp edges. These cut through the protective membranes or bugs or mice, leading to drying out. This approach to controlling mice and other rodents is efficient because the pests cannot develop resistance against it.

What Is Diatomaceous Earth? (DE)

Diatomaceous earth is fossilized remains of aquatic organisms such as ancient, sea-dwelling algae. Their skeletons are made of silica. These accumulate in sediments of rivers, oceans, seas, lakes, and streams, where they are mined and ground into fine powder.

Diatomaceous earth mostly comes from amorphous silicon dioxide. A pesticide with that compound was first made in 1960 and effectively killed insects and mites.

Where Does Diatomaceous Earth Come From?

Diatomaceous earth is ancient phytoplankton found in sedimentary rocks. It is mined for various applications in the industries. The main constituents of diatomaceous earth include the following:

  • 33% silicon
  • 19% calcium
  • 2% iron
  • 5% sodium
  • 3% magnesium.

This product comes in many grades for different purposes. The one we use in our gardens to drive away bugs and rodents is the food-grade diatomaceous earth.

How Long Has DE Been Around?

Step 3: Apply The Mixture To Areas Where Have Mice

Place your diatomaceous earth mixture where the mice live. If you can identify their holes or where they eat in your yard or drain, pour the DE mixture there. But if they disturb you indoors, just place the container in the areas they frequent and leave it open.

The essential oil-infused diatomaceous earth gives off a scent that mice and other rodents will not withstand. That is what will chase them away. They don’t get poisoned but simply pack and leave your property for a better place.

Tips for Using Diatomaceous Earth to Get Rid of Mice

The potency of your diatomaceous earth will fade over time. So, how do you make it last longer or replenish its smell?

  • Keep the diatomaceous earth mixture you are not using in an airtight container.
  • Add water and a few drops of diatomaceous earth to the one whose potency has faded to renew its scent.
  • Reapply the diatomaceous mixture after it rains. Rainwater can wash it away and reduce its effectiveness.
  • Diatomaceous earth powder will remain effective as long as it does not rain or you don’t water your garden.

Other Uses of Diatomaceous Earth

Apart from repelling mice and other rodents, you can use diatomaceous earth for other purposes. Some uses include pest control, water filtration, and human benefits. Let’s get into details of the most common ones.

For Pets

Food-grade diatomaceous earth is an essential mineral source for pets. You can feed it to your dogs, cats, and horses, but the dosage varies depending on the pet and size.

The dosage for dogs is as follows:

  • Under 25 lbs: ½ tsp
  • 25 – 50 lbs: 1-2 tsp
  • 50 – 100 lbs: 1 Tbsp
  • Over 100 lbs: 1-2 Tbsp

The dosage for cats is as follows:

  • Under 7 lbs: ½ tsp
  • 7 – 13 lbs: 1 tsp
  • Over 13 lbs: 1½ tsp

Add 3 ounces of diatomaceous earth to every 10 pounds of feed for horses.

You can also use diatomaceous earth to kill fleas in dogs and cats. Dust your dog’s beddings and other areas frequented with DE. Any flea that gets into contact with it dies.

Human Benefits

Food-grade diatomaceous earth is safe to eat. This natural substance is speculated to have many benefits to humans but not enough evidence to support the claims. Arguably, DE helps with the following:

  • Reduces cholesterol level
  • Encourages healthy skin, nails, teeth, bones, and air.
  • Aids removal of dead skin cells

If it is your first time taking DE or you have not been doing so for some time, the recommended dosage is one teaspoonful 1-2 times a day. You can increase it after about a week when your body has adjusted.  

Taking an overdose of diatomaceous earth can cause constipation. So, stick to the recommended dose to avoid that.

Pest Control

Diatomaceous earth is an effective pesticide that can kill many bugs in your garden. Aphids, ants, thrips, mites, snails, earwigs, and many others cannot survive when they touch it. And the advantage is that it never harms worms or beneficial microorganisms.

The application of diatomaceous earth for pest control is usually printed on the package and is straightforward. You can apply it as a powder or mix it with water for spraying.
