Spray2Grow Gnat Off – Fungus Gnat Root Drench

Spray2Grow Gnat Off is a highly effective root drench designed to instantly eliminate fungus gnat larvae (maggots) in the root zone while helping plants recover quickly from pest damage. Fungus gnats are a common problem in hydroponics, soil growing, coco and greenhouse cultivation, where larvae feed on plant roots and organic matter in the growing medium. Left untreated, infestations can weaken plants, slow growth and damage root systems.

Gnat Off works as a powerful soil sterilant that targets fungus gnat larvae directly in the growing medium. Once applied as a root drench, the solution rapidly eliminates maggots while breaking down into plant-safe nutrients after a few hours. This ensures effective pest control without leaving harmful residues in the root zone.

Because the formula breaks down into plant-safe components, Spray2Grow Gnat Off is suitable for use on organic crops and can be used safely in a wide range of growing environments including hydroponic systems, soil-based growing, coco substrates and greenhouse cultivation.

Available in both 500ml and 5L concentrate sizes, Gnat Off provides a reliable solution for growers looking to control fungus gnats quickly while protecting root health and maintaining strong plant growth.

How Spray2Grow Gnat Off Works

Spray2Grow Gnat Off is applied directly to the root zone as a drench, targeting fungus gnat larvae living in the growing medium. The formula acts quickly to eliminate maggots that feed on plant roots, preventing further damage and helping restore healthy root development.

After application, the active components break down within a few hours into plant-safe nutrients, ensuring the root zone remains safe for continued plant growth while still delivering powerful pest control.

Application

Dilute the concentrate with water and apply directly to the growing medium as a root drench. This allows the solution to penetrate the root zone where fungus gnat larvae live and feed. Proper application helps quickly reduce infestations and protect plant health.
