In the realm of animal care, the use of natural and non-toxic solutions is gaining momentum, addressing challenges such as pest control and overall health maintenance. One such noteworthy substance making strides in this domain is diatomaceous earth (DE), hailing from the fossilized remnants of diatoms. This fine, white powder, primarily composed of silicon dioxide, is derived from the silica-rich skeletons of diatoms, microscopic aquatic organisms that accumulated over millions of years on the ocean floor.

Diatomaceous earth, when processed and finely ground, emerges as a versatile and eco-friendly option for enhancing the well-being of pets and livestock. Its applications span various aspects of animal care, making it a valuable tool in the pursuit of natural solutions. With its roots in amorphous silica, diatomaceous earth works as a multifaceted substance in the management of animals.

One notable application is its role in animal feed. Incorporating diatomaceous earth into feed formulations can contribute to the overall health and wellness of livestock and pets. The amorphous silica content in diatomaceous earth proves beneficial, acting not only as a source of essential trace minerals but also as an anti-caking agent in feed. This dual functionality addresses nutritional needs while preventing clumping and ensuring the consistency of the feed.

Furthermore, diatomaceous earth is often referred to as fossil shell flour, emphasizing its origins and underscoring its natural composition. As an anti-caking agent, it plays a pivotal role in preventing the formation of lumps in animal feed, ensuring that animals receive a well-distributed and nutritionally balanced diet.

In this comprehensive article, we delve into the diverse applications of diatomaceous earth for animals, exploring its safety and efficacy. Whether used as a feed supplement or for pest control, diatomaceous earth emerges as a reliable and environmentally friendly solution for various aspects of animal care. The table of contents provided enables readers to navigate swiftly to the information they seek, reflecting the depth and breadth of this exploration into the world of diatomaceous earth in animal care.  DE works with animals and we are happy to share this information with you.

The Role of Diatomaceous Earth in Pet and Livestock Care

Diatomaceous earth (DE) plays a crucial role in pet and livestock care, offering natural and non-toxic solutions to various challenges in animal husbandry. DE is a fine powder derived from the fossilized remains of diatoms and is gaining recognition for its versatility and eco-friendly attributes in promoting the health and well-being of animals. Its key applications include natural pest control, internal parasite management, pet and livestock food additive, bedding for animals, and pest control in poultry.


DE is known for its non-toxic nature, effectiveness, and safety, making it a valuable tool for animal enthusiasts and farmers seeking sustainable and natural solutions for animal care. Using food-grade DE and consulting with veterinarians for appropriate dosage are crucial safety considerations, ensuring its responsible and effective use in animal care. In summary, diatomaceous earth is emerging as an essential element in the toolkit of conscientious animal caregivers and livestock managers, contributing to healthier and happier animals.

Natural Pest Control

One of the most prominent applications of diatomaceous earth in pet and livestock care is natural pest control. DE has proven efficacy as an insect control agent. When applied to animals, it provides a non-toxic solution for repelling and eliminating external parasites like fleas, ticks, lice, and mites. DE's abrasive texture and desiccating action disrupt the exoskeleton of these pests, leading to their dehydration and eventual demise.


Benefits of DE for Pest Control:

  • Non-toxic: DE is a safe alternative to chemical pesticides, posing no harm to pets, livestock, or the environment.

  • Effective: Its broad-spectrum effectiveness makes it a valuable tool in combating various external parasites.

  • Residue-free: DE leaves no chemical residue on animals or their bedding.

Crawling Insect Control Diatomaceous Earth kills by physical action, not chemical.  After walking or crawling through the product, the tiny diatoms polish off the insect’s waxy coating when they move.  When the waxy coating is finally polished through the product sucks the body fluids from the insect, rendering it dead.

Drs. Kim Bloomer & Jeannie Thomason, hosts of the online radio show, Animal Talk Naturally, have this to say about our Perm-Guard Crawling Insect Control Diatomaceous Earth:

"Our work is based on natural, preventive care for animals, so of course we are always on the lookout for good, quality NATURAL products to help our clients and our listening audience that won’t break the bank.  We have long been proponents of Crawling Insect Control Diatomaceous Earth as a natural pest control for all animals. EARTHWORKS HEALTH has provided us the high quality and affordability in their Perma-Guard product that we look for in our own personal use as well as for our clients."

Thank you Dr. Kim Bloomer & Dr. Jeannie Thomason!

Internal Parasite Control

Food-grade diatomaceous earth is suitable for oral consumption by animals. It is believed to help control internal parasites, such as roundworms, tapeworms, and other gastrointestinal pests. The abrasive particles in DE may assist in disrupting the life cycle of these parasites, ultimately leading to their expulsion from the digestive system.


Benefits of DE for Internal Parasite Management:

  • Natural approach: DE offers a non-toxic and natural alternative to chemical de-wormers.

  • Digestive health: Some animal owners have reported improvements in overall digestive health after incorporating DE into their animals' diets.

Livestock Feed and Pet Food Additive

Diatomaceous earth can be used as a feed additive for livestock and mixed into pet food for dogs and cats. It is considered an effective means of promoting overall health and well-being. DE is believed to have benefits for gastrointestinal health, particularly in cattle, horses, and poultry. Its abrasive action can contribute to improved digestion, while its silica content may enhance bone and joint health.


Benefits of DE in Pet Food and Livestock Feed:

  • Improved digestion: DE's abrasive nature can help break down feed more effectively.

  • Enhanced bone and joint health: The silica content in DE may contribute to improved bone and joint health in livestock.
