De-Gnat Advanced Insect Shield 10Kg

De-Gnat Advanced Insect Shield 10kg

De-Gnat Advanced Insect Shield 10kg is a natural, non-toxic substrate barrier made from Diatomaceous Earth (DE), a naturally occurring source of silica and calcium derived from earth minerals.

Designed for use with coco, peat and other growing media, De-Gnat forms an abrasive physical barrier across the surface of the substrate to help control unwanted insects and pests living or breeding within the growing medium.

Its specially sized DE granules create a long-lasting protective layer while also improving the physical properties of the root zone.

Key Benefits

• Creates a natural physical barrier over growing media
• Helps control unwanted insects within the substrate
• Provides a natural source of silica
• Improves substrate aeration and porosity
• Helps reduce compaction
• Supports nutrient uptake and absorption
• Encourages beneficial microbial activity
• Provides excellent thermal insulation
• Helps maintain more stable root-zone conditions
• pH stable
• Naturally sourced and refined
• Non-toxic
• Suitable for coco and peat-based growing media

How Does De-Gnat Advanced Insect Shield Work?

De-Gnat is made from specially sized Diatomaceous Earth granules that form a dry, abrasive layer across the top of your growing medium.

This physical barrier helps create an unfavourable environment for unwanted insects moving through or emerging from the substrate.

At the same time, the mineral structure of De-Gnat improves airflow within the medium, reduces compaction and contributes naturally occurring silica to the root zone.

Improve Root-Zone Aeration and Nutrient Availability

De-Gnat does more than provide a protective surface barrier.

When used within growing media, its porous mineral structure can help improve air movement around the roots and create a more open substrate structure.

This can support:

• Better root-zone aeration
• Improved nutrient availability
• Reduced substrate compaction
• More efficient nutrient uptake
• Beneficial microbial activity
• Improved thermal regulation

Natural Source of Silica

Diatomaceous Earth naturally contains silica, making De-Gnat a useful mineral amendment for growing media.

Silica can support stronger plant structure and overall plant resilience while the DE granules simultaneously improve the physical characteristics of the substrate.

How to Apply De-Gnat

For use as a surface barrier:

1. Apply an even 1cm to 3cm layer of De-Gnat across the top of the growing medium.
2. Ensure the entire surface of the substrate is fully covered.
3. Maintain an even layer throughout the plant's growing cycle.
4. Reapply or replenish De-Gnat when necessary.
5. If irrigation disturbs the DE layer, redistribute or add additional product to restore complete coverage.

For best results, keep the protective layer consistent across the entire substrate surface.

Secondary Use – Natural Alternative to Perlite

De-Gnat can also be mixed throughout coco or peat-based substrates as a natural alternative to perlite.

Mixing De-Gnat into the growing medium can help:

• Increase porosity
• Improve aeration
• Reduce compaction
• Improve drainage and root-zone structure
• Add a natural mineral source of silica

Approximate Coverage

One 10kg bag of De-Gnat Advanced Insect Shield can cover approximately:

• 6 × 30L pots
• 4 × 50L pots
• 2 × 95L pots

Actual coverage may vary depending on pot dimensions and application depth.
