1. Eliminate Gnats

Amazing Uses of Diatomaceous Earth in the Garden 2

You can find these small, winged insects in crammed-up spots like garbage dumps, stale vegetables, overripe fruits, over-watered soil as well as potted plants with decaying soil. Basically, anything wet or damp forms a suitable habitat for these pests. Sometimes when you buy potted plants, they come with a batch of pesky gnats that lay eggs in the soil and feed on algae, fungi and decaying plant matter present in the soil. They are damaging to plant’s health.

Diatomaceous earth can help you to get rid of them. Just dust your potted plants with DE to keep the topsoil dry and desiccate gnats or larvae that land on the plant. When you water your plants, add some more DE to the soil again. This small measure goes a long way to tackle a severe gnat problem, in addition to a few other insects such as blackflies, whiteflies, and other flying insects. Here’s an article on it in detail!

2. Deter Wasps & Hornets

It’s important to emphasize that wasps too play a vital role in maintaining the natural balance of your garden and devouring pests like caterpillars and aphids. However, if there is a wasp population in your garden you can’t live with, you may need to get rid of them.

Thankfully, Diatomaceous earth is an effective wasp killer. Just apply a fair amount of DE in areas where wasps have caused a problem and make sure to provide sufficient coverage. It’s advisable to use the wet application if the climate is dry where you live. Research has shown that wasps and hornets do not build nests on DE-treated areas. Repeat this process every three weeks for continual prevention.

3. Get Rid of Flies

Flies can be incredibly frustrating. These teeny-weeny creatures feast on your valuable garden edibles and impact your plants’ health negatively, hence your best bet is to reduce, if not eliminate their colonization in your garden. Instead of using counter-productive chemical pesticides, use diatomaceous earth around the yard and farm to repel away flies naturally. Moisture and smell attract flies, but the use of DE prevent this effectively. Check out this article on Mother Earth News and this one too for help.

4. Get rid of maggots

Unused piles of manure and compost often house the larvae of several types of flies that infest them. Some of these, like the soldier fly, are largely harmless as they neither sting nor spread infectious disease. But unless you are sure of them, or have a coop of chickens to tackle the maggot problem for you, you might want to eliminate them as fast as you can. If you are all for organic products and hate the idea of subjecting your garden to harsh chemicals, then the diatomaceous earth is most probably your best bet. Just apply it all over the affected area and let it do its job.

5. Keep Slugs Out of Your Garden

6. Protect Your Home from Termites

One of the best ways to protect your home from termite colonies is to preclude them from entering in the first place. These pests basically lurk in the dark corners of your garden, where they serve an important role in breaking down decaying plant matter and digesting wood to form soil. Termites typically create the biggest problems during the swarming season, when they multiply quickly and infest your home interiors as well.

If you live in a place where termites are common, you probably know the harm they can cause. Well, Diatomaceous earth is an effective thing to help you in both preventing, as well as removing termite colonies. It’s economical, chemical-free, and easy to apply!

Ants swarm the family picnic, garden tea party, backyard BBQ and whatever little food they can get their tiny legs on. So, cleaning up what’s bringing them into your garden is half the battle won. The other half can be won by using diatomaceous earth, as it’s a natural ant repellent that works in a non-toxic, human-friendly way to disrupt non-discernible ant trails and prevent future ant problems. And all that too without contaminating your ornamentals and edibles! Simply, dust the plants and anthills with DE to get rid of them.

8. Increase Porosity of Soil

While it doesn’t offer much regarding nutrition, it does have the capacity to retain fertilizers and release it gradually to the roots. That, coupled to its porosity makes it a wonderful addition to the soil for container gardening and a good growing medium for bonsai and hydroponic culture. Just mix it with potting soil to improve drainage and air flow in the root zone.

9. Preserve and Dry Flowers

10. Deodorize Pest-Attracting Litter

In addition to acting as a mechanical pesticide, one of the most important diatomaceous earth uses in the garden is eliminating noxious odors. If you have a pet that tends to use the garden as its toilet, ensure to mix in some DE onto the topsoil or just apply it liberally over its favorite place. Also, using diatomaceous earth helps to deodorize the compost pile and keep it from acting as a potential habitat for nuisance pests.

11. Control Aphids

Aphids are the most prominent pests gardeners have to fight continuously. When overlooked they multiply rapidly and cause widespread damage to the garden in no time. Diatomaceous earth is an effective solution to get rid of aphids. Simply dust the infested area with the dry powder, or mix it with some water and apply with a sprayer. Repeat the procedure every few days for better results.

12. Get Rid of Rodents

Rodents like mice, moles, rats and rabbits can wreck your garden in no time, and if you don’t want to kill them, diatomaceous earth is here to help. Rodents hate the powerful smells of essential oils like peppermint and lemon citrus and as you might already know that diatomaceous earth is an excellent absorbent. These two ingredients can be combined to create the most powerful organic rodent repellent that can keep the rodents at bay.

The best thing is that it is highly cost effective, is completely safe and at the same time smells heavenly. Check out the recipe here.

13. Reduce Tick Population

Summer is commonly signified by a warm, sultry weather, bright flowers swaying in the gentle breeze and giant colonies of blood-sucking, parasitic arachnids, i.e. ticks. If you enjoy hiking, gardening, and playing in the backyard, you must have encountered these pesky little suckers. They are extremely difficult to handle once they attach themselves to your body. Plus, they often transmit incurable disease like Tularemia, Lyme disease, Rocky Mountain spotted fever and so on. One way to deal with their infestation is to dust the entire yard and lawn with a generous amount of diatomaceous earth. It’s advisable to use an applicator for this purpose and repeat the process once in every month during the flea season.

  1. Thanks for these useful tips!
    One of my problems in summer is the insufferable insect bites I get whenever I go outdoors.The stings, itchiness, and scars left on my skin.

  2. Barbara Simoes, if using food grade Diatomaceous Earth you don’t need a mask. It is perfectly safe for humans and pets.

  3. I live on Cape Cod and we have these red beetles. They have sort of a more oval shape to them instead of being round like a ladybug. They love to eat Lilies, especially Easter Lilies……that is until I sprinkled Diatomaceous Earth on them. I read the only thing to get rid of these beetles are Wasps, and who wants Wasps in their flower garden? I sprinkle some Diatomaceous Earth on my Lilies as soon as I see them pop up. If it rains I reapply. I just tried this method last year, and last year was the first year all my Lilies came to bloom in many, many years.

  4. I’m so confused! I want to use DE in my yard. If I apply it dry, and then it rains (or otherwise gets wet), I need to reapply. HOWEVER, I can apply DE mixed with water to the entire lawn, as well? I must be missing something. Does anyone know why you can apply it wet but if it’s dry and gets wet it must be reapplied?
