Fungus Gnat Larvae Treatment Drops – Tanlin 20ml | CX Horticulture

Tanlin Drops – Fungus Gnat Larvae Treatment, Just a Few Drops at a Time

Type: Biological. A highly concentrated, non-toxic fungus gnat treatment that stops the larvae from developing into adult flies.

Fungus gnats are the flies nobody invited: tiny, black and suddenly everywhere around your houseplants. The adults are just a nuisance. The real problem is their larvae, living in damp compost and chewing fine roots. Tanlin goes after the larvae. Add a few drops to your watering can and it's taken up as you water; when the larvae feed, they stop developing into adults. No adults, no eggs, no next generation. It isn't instant (the population falls over a couple of weeks), but it breaks the cycle properly. And because a 20ml bottle treats up to 2,000 litres, it's one of the cheapest fixes there is, per watering.

Perfect For

• Houseplants with fungus gnats, especially in damp, peat-based compost
• Seedlings, cuttings and propagation trays
• Indoor gardens and greenhouses, as a preventative with every feed
• Growers in soil, coco and hydro, including edible crops

Why It Works

• Stops larvae from developing into adult flies, breaking the life cycle
• Non-toxic and safe for plants, people and pets
• Extremely concentrated: 20ml treats up to 2,000 litres
• Can be used right up to harvest

How to Use

Soil and coco: 1 drop per 2 litres of water. Drench the growing medium thoroughly. Repeat weekly, or every 3 days for a bad infestation.

Recirculating systems: 1ml (40 drops) per 100 litres of nutrient solution.

Don't use it alongside hydrogen peroxide, which makes it much less effective.

🌿 Rose's Pro-Tip: Tanlin deals with the larvae; a yellow sticky trap deals with the adults already flying. Use both, and let the top of the compost dry out between waterings, and you'll be gnat-free within a few weeks.
