Diatomaceous Earth for Crickets

Updated: Nov 7

Crickets can be both a boon and a bane depending on their environment. While they play a vital role in the ecosystem as decomposers and a food source for other animals, they can also be a nuisance indoors, chirping through the night and damaging fabrics, plants, and paper. If you’re looking for an eco-friendly, non-toxic way to get rid of crickets, diatomaceous earth (DE) offers an effective solution to reduce the cricket population in and around your property. This natural remedy is not only safe for humans and pets but is also environmentally responsible. Let's dive into what diatomaceous earth is, how it works on a house cricket problem, and how you can use it effectively to create a natural barrier.



What is Diatomaceous Earth?

Diatomaceous earth is a fine, powdery substance made from the fossilized remains of diatoms, a type of ancient algae. These fossilized remains form a sedimentary deposit that results in DE powder when mined and crushed. The silica-based substance has sharp, microscopic edges that are harmless to humans and pets but lethal to many pests, including household crickets and even camel crickets, cockroaches, earwigs, whether indoor or outdoor.


DE is used in various industries for filtration and insulation, and it is even a mild abrasive in products like toothpaste. However, its use as a natural insecticide has made it particularly popular among those seeking chemical-free, natural cricket control.



How Does Diatomaceous Earth Work on Crickets?

While diatomaceous earth looks like a harmless powder, it has razor-sharp edges at the microscopic level. When crickets come into contact with DE, the powder clings to their exoskeletons, and the sharp particles cut through their waxy outer layer. This causes the cricket, even mole crickets, to lose moisture and dehydrate, eventually leading to its death.


Because DE works mechanically rather than chemically, insects cannot develop a resistance to it, making it a long-term solution for cricket control. Additionally, it remains effective as long as it stays dry, so it’s perfect for use in indoor areas and dry climates. Cricket eggs do need to hatch for that nymph or adult to come into contact with DE.



Benefits of Using Diatomaceous Earth for Crickets


  • Non-Toxic and Safe for Humans and Pets: Diatomaceous earth is non-toxic and safe to use in homes, gardens, and even around food preparation areas. This makes it a popular choice for pet owners and families looking for a safe alternative to chemical pesticides.


  • Eco-Friendly: Unlike chemical pesticides, DE doesn't pollute the environment or pose a threat to wildlife. It’s biodegradable and poses no long-term environmental risks.


  • Long-Lasting: As long as DE stays dry, it remains effective. Unlike traditional pesticides that may need frequent reapplications or lose their potency over time, DE can keep working indefinitely under the right conditions.


  • Inexpensive: DE is affordable and readily available online compared to the hundreds of dollars pest control services charge you to even take a look at your property. A small amount goes a long way, making it a cost-effective pest control solution.





How to Use Diatomaceous Earth for Cricket Control


To effectively control a cricket infestation using diatomaceous earth, follow these steps:


1. Identify Problem Areas

Crickets are most active at night, so their chirping will often give away their hiding spots. Look for them in dark, damp areas such as basements, garages, crawl spaces, and around pet food or food you have left out. They may also hide in closets, under furniture, or behind appliances. To help identify a cricket, first look for the long antennae that they have.


2. Apply Diatomaceous Earth

Once you've located the areas where crickets are present, lightly sprinkle a thin layer of diatomaceous earth. Focus on the following areas:


  • Entry points: Doors, windows, and cracks where crickets may enter.

  • Hiding places: Behind furniture, along baseboards, under appliances, and in closets.

  • Outdoors: Around the perimeter of your home, especially near doors and windows, and in gardens or mulch beds where crickets are common.


Use a duster or shaker to apply DE, as it helps create a fine, even layer. The goal is not to pile it up but to spread a light coating so that crickets will crawl through it.


3. Reapply as Needed

If using DE outdoors, you may need to reapply it after rain or if it becomes damp, as moisture can reduce its effectiveness. Indoors, a single application may be sufficient for ongoing protection, but you can reapply every week or so if crickets persist.


4. Monitor and Clean Up

After a few days to a week, you should begin to notice fewer crickets. Dead crickets can be swept up, and if DE becomes dusty or unsightly in visible areas, you can vacuum or wipe it away. However, leaving a thin, invisible layer of DE in less-trafficked areas will continue to protect your home and prevent future infestations. Also, a great idea to put some sticky traps around entryways and corners of rooms to work in conjunction with diatomaceous earth.



Precautions When Using Diatomaceous Earth


While DE is safe to handle, it’s important to not use filter grade diatomaceous earth, especially in homes with pets and children. We recommend using our crawling insect control diatomaceous earth. Avoid breathing in the dust when applying, as it can irritate the lungs. Wearing a mask or applying DE with a duster can help prevent inhalation. If you’re using DE outdoors, reapply after heavy rain, as moisture diminishes its effectiveness.



Diatomaceous Earth for Cricket Prevention


Once you’ve managed to eliminate crickets in your home, diatomaceous earth can serve as a preventative measure. Regularly applying it in entry points, around doors and windows, and in other potential hiding spots will discourage new crickets from entering. By combining DE with other preventative measures such as sealing cracks and crevices, reducing moisture, and removing clutter, you can significantly reduce the likelihood of future infestations.



Conclusion


Diatomaceous earth is a safe, natural, and effective solution for controlling crickets in and around your home. Whether you’re dealing with a cricket infestation or looking for a preventative measure, DE offers long-lasting results without the risks associated with chemical pesticides. By understanding how to apply it properly and maintaining consistent use, you can enjoy a cricket-free environment while keeping your home safe for your family and pets.


If crickets are driving you up the wall with their incessant chirping, try using diatomaceous earth—it's a simple yet powerful remedy that brings peace and quiet back to your home.
