Diatomaceous Earth Powder for Fungus Gnats

Natural mineral dust to help manage soil pests in houseplants. Finely milled, food-grade diatomaceous earth that works by physical contact, not chemicals.

Why you’ll love it

  • 100% food grade amorphous silica

  • Targets the soil stage of fungus gnats

  • Also helpful around pots for slugs and at the soil line for root mealybugs

  • Packed in a resealable zip bag to keep it clean and dry

Best for

  • Breaking the fungus gnat life cycle in the top layer of houseplant soil

  • Creating a dry barrier around pots kept indoors or under cover for slugs

  • Intercepting root mealybug crawlers at the soil line during repotting

How to use

  1. Let the top 1 to 2 cm of soil dry. Lightly dust a thin, even layer over the soil surface and around the inner rim and drainage holes.

  2. For hotspots, work a small pinch into just the top layer. Avoid burying delicate roots.

  3. Reapply after each watering once the surface dries. Diatomaceous earth must be dry to be effective.

  4. Improve drainage and avoid overwatering. For heavy infestations, repot into fresh mix. We recommend Highland Moss premium potting mix.

How does Diatomaceous Earth work?
Diatomaceous Earth is a naturally occurring sand extract that forms over millions of years. It has a high silica content that absorbs lipids and fats from the waxy outer layer of the exoskeletons of many species of insects. This kills the fungus gnat and keeps your plants happy.
Notes: DE acts as a desiccant and abrasive. It works only while dry and undisturbed.

Also helps with

  • Slugs as a dry ring around pots in protected, dry spots

  • Root mealybugs during repotting when used as a light dust at the soil line, alongside sanitation

What’s in the bag

  • Ingredients: 100% food grade diatomaceous earth

  • Packaging: resealable zip bag

Safety and care

  • Avoid inhaling dust and keep away from eyes. A simple dust mask is sensible during application.

  • Store sealed in a cool, dry place.

Eco notes

  • We reuse and recycle packaging materials where possible.

  • Pair with our neem oil or eco friendly pest spray for leaf pests.

    Thank you so much for holding back the delivery due to it clashing with the funeral of my dear mother in law, it was truly appreciated. My wife was also taken aback by your thoughtfulness by including a lovely bouquet of dried flowers and card with kind words. The flowers will always remind us of Elaine and sit pride of place on the sideboard in our dining room. You are truthfully some of the very best people we have dealt with, online and on the phone.
