Is this diatomaceous earth safe for pets and humans?

Yes. This is food-grade diatomaceous earth, which is safe for use around people, pets, and edible plants when used as directed. Always avoid inhaling the fine dust during application by wearing a mask.

How do I apply diatomaceous earth in the garden?

You can dust it lightly onto plants and soil, or mix it with water (about 1 cup per 4 litres) and spray it. Reapply after rain or heavy watering, as it only works when dry.

Diatomaceous Earth - Food Grade (1.25kg) - Natural, organic pest control & multi-purpose solution for your home, garden & pets.

Diatomaceous Earth (DE) is a fine, powdery substance made from the fossilized remains of tiny aquatic organisms called diatoms. This food-grade version is sourced from freshwater deposits and contains no harmful additives or chemicals. It consists primarily of natural silica with microscopic, razor-sharp edges that are completely safe for humans, pets, and the environment when used as directed.

Key benefits:

Effective, non-toxic insect control: Works mechanically by cutting through the exoskeletons of crawling insects, causing them to dehydrate and die. It targets common garden and household pests like aphids, thrips, ants, mites, bed bugs, snails, slugs, fleas, cockroaches, and more—without using harsh chemical pesticides.
Safe for organic gardening: Ideal for vegetable gardens, flower beds, and around edible plants. It leaves no toxic residues and won't harm beneficial insects when applied carefully.
Versatile household & pet use: Helps control fleas and ticks in pet bedding or carpets (food-grade is safe around animals). Can also be used as a gentle abrasive cleaner or for minor DIY applications.
Long-lasting when dry: Remains effective as long as it stays dry, providing ongoing protection in dry conditions.
Eco-friendly & sustainable: All-natural, non-toxic to mammals, birds, and earthworms. Great for chemical-free living.

How to use it:

In the garden (as a Dust or Spray):

Dry application: Lightly dust dry powder directly onto plants, soil, or around the base of plants where pests travel. Reapply after rain or heavy watering.
Wettable spray mix (recommended to reduce airborne dust): Mix 1 cup (approx. 236 ml) of DE per gallon (about 4L) of water. Stir well and keep agitated while spraying. Apply to leaves, stems, and soil. It can also be painted onto trees or shrubs for targeted protection.
Best applied in the evening to minimize impact on pollinators like bees.

For pets & home:

Sprinkle lightly in pet bedding, carpets, or cracks where pests hide. Vacuum after a few days and reapply as needed.
Always use food-grade DE for any areas around people or animals.

Safety tips:

Wear a dust mask and eye protection during application to avoid inhaling the fine powder.
Keep it dry for maximum effectiveness—moisture deactivates it.
Store in a cool, dry place.

This powerful, multi-use product is perfect for gardeners, pet owners, and anyone seeking natural solutions. One 1.25kg pack goes a long way... ideal for both small home gardens and larger applications. Grow healthier plants and enjoy a pest-free environment the natural way!
